AP Macroeconomics Practice Questions

1. Which statement best captures why scarcity is considered the central problem in economics?
   • Because society's wants are virtually unlimited while the resources to satisfy them are limited
   • Because all goods eventually become more expensive as time passes
   • Because governments cannot produce enough money for everyone
   • Because consumers usually buy more than they actually need

   Correct answer: Because society's wants are virtually unlimited while the resources to satisfy them are limited

   Scarcity is the central economic problem because society's wants are virtually unlimited while the resources to satisfy them are limited. This gap between boundless wants and finite means is what forces every individual, firm, and government to make choices about how resources are used. Rising prices, money supply, and overconsumption are downstream phenomena rather than the underlying cause that defines economics.

2. When the government decides to use a fixed budget to build a new highway instead of a new hospital, the value of the hospital that was not built represents what concept?
   • Sunk cost
   • Marginal cost
   • Opportunity cost
   • Fixed cost

   Correct answer: Opportunity cost

   The value of the hospital that was not built is the opportunity cost of choosing the highway, because opportunity cost is the value of the next-best alternative forgone when a decision is made. Since the budget could fund only one project, selecting the highway necessarily meant giving up the hospital. A sunk cost is already spent and unrecoverable, a marginal cost is the cost of one additional unit, and a fixed cost does not vary with output, so none of those describe a forgone alternative.

3. An economy is operating at a point that lies outside its current production possibilities curve. What does this indicate?
   • The economy is using its resources efficiently
   • The economy has unemployed resources
   • The point is unattainable given current resources and technology
   • The economy is experiencing increasing opportunity costs

   Correct answer: The point is unattainable given current resources and technology

   A point outside the current production possibilities curve is unattainable given the economy's existing resources and technology. The curve marks the maximum combinations of two goods that can be produced when all resources are fully and efficiently used, so any point beyond it cannot be reached without acquiring more resources or better technology. Points on the curve are efficient, points inside reflect unemployed resources, and the curve's bowed shape shows increasing opportunity costs.

4. A production possibilities curve is drawn as a straight, downward-sloping line rather than bowed outward. What does this shape imply about opportunity cost?
   • Opportunity cost is constant as production shifts between the two goods
   • Opportunity cost increases as more of one good is produced
   • Opportunity cost falls to zero at the endpoints
   • Opportunity cost cannot be determined from a straight line

   Correct answer: Opportunity cost is constant as production shifts between the two goods

   A straight-line production possibilities curve implies that opportunity cost is constant as production shifts between the two goods. A constant slope means each additional unit of one good always requires giving up the same amount of the other, which happens when resources are equally suited to producing both goods. A bowed-outward curve, by contrast, signals increasing opportunity costs as resources become less interchangeable.

5. Maria can knit 4 scarves or 8 hats in a day, while Jon can knit 2 scarves or 6 hats in a day. Who has the comparative advantage in producing scarves?
   • Jon, because his opportunity cost per scarf is lower
   • Maria, because her opportunity cost per scarf is lower
   • Both have the same opportunity cost per scarf
   • Neither, because Maria can make more of both goods

   Correct answer: Maria, because her opportunity cost per scarf is lower

   Maria has the comparative advantage in scarves because her opportunity cost per scarf is lower. For Maria, one scarf costs 2 hats (8 hats divided by 4 scarves), while for Jon one scarf costs 3 hats (6 hats divided by 2 scarves), so Maria gives up fewer hats per scarf. Comparative advantage depends on lower opportunity cost, not on who can produce more in total, so Maria's higher overall output does not by itself decide the question.

6. Suppose Country A can produce more of both wheat and steel per worker than Country B. What does this situation describe?
   • Country A has a comparative advantage in both goods
   • Country A has an absolute advantage in both goods
   • Country B should refuse to trade with Country A
   • Neither country can gain from specialization

   Correct answer: Country A has an absolute advantage in both goods

   Country A having greater output per worker in both wheat and steel means it has an absolute advantage in both goods, since absolute advantage is the ability to produce more with the same resources. This is distinct from comparative advantage, which depends on opportunity costs, and a country cannot hold the comparative advantage in everything. Even though Country A is more productive overall, both nations can still gain by specializing according to comparative advantage and trading.

7. A nation classifies its economic resources into categories such as natural resources, the workforce, machinery and tools, and the risk-taking organizers of production. These categories are collectively known as what?
   • The components of aggregate demand
   • The four factors of production
   • The functions of money
   • The phases of the business cycle

   Correct answer: The four factors of production

   These categories are collectively known as the four factors of production: land (natural resources), labor (the workforce), capital (machinery and tools), and entrepreneurship (the risk-taking organizers). Together they are the inputs used to produce goods and services in any economy. The components of aggregate demand describe spending, the functions of money relate to its uses, and the business cycle describes fluctuations in output, so none of those name productive resources.

8. Which scenario is the clearest illustration of the law of demand?
   • A coffee shop raises its prices and sells fewer cups per day, all else equal
   • A new health study causes more people to buy oranges at every price
   • Rising household incomes increase the demand for restaurant meals
   • A frost destroys part of the orange crop, reducing supply

   Correct answer: A coffee shop raises its prices and sells fewer cups per day, all else equal

   A coffee shop raising its prices and selling fewer cups, all else equal, is the clearest illustration of the law of demand, which states that quantity demanded falls as a good's own price rises. This describes movement along a single demand curve caused only by a price change. The health study and higher incomes shift the entire demand curve, and a frost affects supply rather than demand, so none of those isolate the price–quantity relationship.

9. An economy that is currently producing at a point inside its production possibilities curve moves to a point on the curve. What is the most accurate description of this change?
   • The economy has experienced long-run economic growth
   • The economy has reduced its productive capacity
   • The economy has increased its opportunity costs
   • The economy has moved from inefficiency toward full and efficient resource use

   Correct answer: The economy has moved from inefficiency toward full and efficient resource use

   Moving from a point inside the curve to a point on the curve means the economy has moved from inefficiency toward full and efficient resource use, putting previously idle or underused resources to work. This is not economic growth, because growth requires the entire curve to shift outward as productive capacity expands. The curve itself has not moved, so productive capacity is unchanged and the shape determining opportunity cost is unaffected.

10. In a two-country model, Country P gives up 3 bushels of corn for each bicycle it makes, while Country Q gives up 5 bushels of corn for each bicycle it makes. Which trade pattern allows both countries to benefit from specialization?
    • Country P specializes in bicycles and Country Q specializes in corn
    • Country P specializes in corn and Country Q specializes in bicycles
    • Both countries should produce only bicycles
    • Neither country should trade because corn is more valuable

    Correct answer: Country P specializes in bicycles and Country Q specializes in corn

    Both countries benefit when Country P specializes in bicycles and Country Q specializes in corn, because each then focuses on its comparative advantage. Country P gives up only 3 bushels of corn per bicycle versus Country Q's 5 bushels, so P has the lower opportunity cost in bicycles. That leaves Q with the lower opportunity cost in corn, so Q should produce corn, and trade between the two raises total output for both.

11. Why does the principle of scarcity apply even to a very wealthy individual who can afford almost anything?
    • Because wealthy people always want to pay lower prices
    • Because the individual's time and other resources remain limited, forcing trade-offs
    • Because inflation erodes the value of large amounts of money
    • Because taxes reduce the total amount a person can spend

    Correct answer: Because the individual's time and other resources remain limited, forcing trade-offs

    Scarcity applies even to the very wealthy because their time and other resources remain limited, forcing trade-offs about how to use them. A person cannot attend two events at once or be in two places at the same moment regardless of wealth, so choices and their opportunity costs persist. Inflation and taxes affect purchasing power but are not what makes scarcity universal, and the desire for lower prices is unrelated to the limited nature of time itself.

12. Which definition best describes gross domestic product as used in national income accounting?
    • The total income earned by a nation's citizens regardless of where they work
    • The market value of all final goods and services produced within a country in a given period
    • The sum of all wages paid to workers in the manufacturing sector
    • The total value of all goods, including used and resold items, traded in a year

    Correct answer: The market value of all final goods and services produced within a country in a given period

    Gross domestic product is the market value of all final goods and services produced within a country in a given period. It counts production occurring inside the country's borders, uses market prices to express different goods in common terms, and includes only final goods to avoid double counting. Income earned abroad belongs to gross national product, wages in one sector are far too narrow, and used or resold items are excluded because they were counted when first produced.

13. In a simplified economy, consumer spending is $700 billion, investment is $150 billion, government purchases is $200 billion, exports are $90 billion, and imports are $60 billion. Using the expenditure approach, what is GDP?
    • $1,080 billion
    • $1,200 billion
    • $1,140 billion
    • $1,050 billion

    Correct answer: $1,080 billion

    GDP equals $1,080 billion. The expenditure approach adds consumption, investment, government purchases, and net exports, where net exports is exports minus imports. Here net exports is $90 billion minus $60 billion, or $30 billion, and adding $700 plus $150 plus $200 plus $30 gives $1,080 billion. The other totals come from forgetting to subtract imports or mishandling the net exports term.

14. An economy's total output of goods and services valued at the prices that prevailed in the year the output was produced is known as what?
    • Real GDP
    • Potential GDP
    • Nominal GDP
    • Per capita GDP

    Correct answer: Nominal GDP

    Output valued at the prices prevailing in the year it was produced is nominal GDP, sometimes called current-dollar GDP. Because it uses current prices, nominal GDP can rise simply because prices increased even if physical output did not change. Real GDP instead values output at constant base-year prices to strip out price changes, potential GDP is the full-employment output level, and per capita GDP divides output by population.

15. The labor force in a country is 150 million people, and 9 million of them are unemployed. What is the unemployment rate?
    • 9.0 percent
    • 5.0 percent
    • 6.0 percent
    • 15.0 percent

    Correct answer: 6.0 percent

    The unemployment rate is 6.0 percent. The unemployment rate equals the number of unemployed divided by the labor force, then multiplied by 100. Dividing 9 million by 150 million gives 0.06, which is 6.0 percent. The other figures result from dividing by the wrong base or confusing the count of unemployed with the rate itself.

16. A factory worker is laid off because automation permanently eliminated her position, and her skills no longer match the jobs employers are hiring for. Which type of unemployment does this best illustrate?
    • Frictional unemployment
    • Cyclical unemployment
    • Seasonal unemployment
    • Structural unemployment

    Correct answer: Structural unemployment

    This best illustrates structural unemployment, which arises when workers' skills no longer match the jobs available because of changes in technology or the structure of the economy. Automation permanently removing a job and creating a mismatch between skills and openings is the defining case. Frictional unemployment involves short transitions between jobs, cyclical unemployment results from downturns in the business cycle, and seasonal unemployment follows predictable changes in the time of year.

17. The natural rate of unemployment is best described as the unemployment rate that exists when which condition holds?
    • Cyclical unemployment is zero and the economy produces at full-employment output
    • All forms of unemployment, including frictional and structural, have been eliminated
    • The economy is in a deep recession with widespread layoffs
    • Inflation has been driven all the way down to zero

    Correct answer: Cyclical unemployment is zero and the economy produces at full-employment output

    The natural rate of unemployment exists when cyclical unemployment is zero and the economy produces at its full-employment output. At this point only frictional and structural unemployment remain, since these reflect normal job search and skill mismatches rather than a downturn. The natural rate is never zero because some frictional and structural unemployment always persists, it does not describe a recession, and it is unrelated to driving inflation to zero.

18. Which statement best explains what the consumer price index measures?
    • The total quantity of goods a typical household produces each year
    • The average change over time in the prices paid by urban consumers for a fixed market basket of goods and services
    • The interest rate banks charge their most creditworthy customers
    • The market value of all final goods and services produced in the economy

    Correct answer: The average change over time in the prices paid by urban consumers for a fixed market basket of goods and services

    The consumer price index measures the average change over time in the prices paid by urban consumers for a fixed market basket of goods and services. By tracking the cost of a representative basket, the CPI captures how the cost of living changes and serves as the main gauge of inflation faced by households. It is not a measure of household production, an interest rate, or total economy-wide output, which is GDP.

19. A market basket cost $200 in the base year and $230 in the current year. What is the value of the consumer price index in the current year?
    • 130
    • 30
    • 115
    • 87

    Correct answer: 115

    The current-year consumer price index is 115. The CPI equals the cost of the basket in the current year divided by its cost in the base year, multiplied by 100. Dividing $230 by $200 gives 1.15, which becomes 115 after multiplying by 100. The figure 115 reflects that prices rose 15 percent above the base year, while the other answers mix up the percentage change with the index value or invert the ratio.

20. The consumer price index rises from 120 in one year to 126 the next year. What is the inflation rate over that period?
    • 6.0 percent
    • 5.0 percent
    • 4.8 percent
    • 12.6 percent

    Correct answer: 5.0 percent

    The inflation rate is 5.0 percent. The inflation rate equals the change in the price index divided by the starting index, multiplied by 100. The index rose by 6 points, and dividing 6 by the original 120 gives 0.05, or 5.0 percent. Using 6 points as the rate ignores the base, and dividing by the later value of 126 produces the incorrect 4.8 percent.

21. During which phase of the business cycle does real GDP reach its lowest point before beginning to rise again?
    • Peak
    • Expansion
    • Recession
    • Trough

    Correct answer: Trough

    Real GDP reaches its lowest point at the trough, the turning point at the bottom of the business cycle just before recovery begins. From the trough the economy enters expansion, during which output and employment rise. The peak is the high point where expansion ends, and a recession is the period of falling output between a peak and a trough rather than the lowest point itself.

22. Suppose a borrower agrees to a loan with a nominal interest rate of 8 percent during a year when the inflation rate turns out to be 3 percent. What is the approximate real interest rate?
    • 11 percent
    • 5 percent
    • 3 percent
    • 8 percent

    Correct answer: 5 percent

    The approximate real interest rate is 5 percent. The real interest rate roughly equals the nominal interest rate minus the inflation rate, which captures the true increase in purchasing power. Subtracting 3 percent inflation from the 8 percent nominal rate leaves 5 percent. Adding the two rates gives the incorrect 11 percent, and using either rate alone ignores the adjustment for inflation.

23. In the simple circular flow model of a private economy, what flows from households to firms through the product market?
    • Wages, rent, interest, and profit
    • Spending on goods and services
    • Land, labor, capital, and entrepreneurship
    • Tax revenue and government transfers

    Correct answer: Spending on goods and services

    In the circular flow model, spending on goods and services flows from households to firms through the product market. Households purchase the output that firms produce, sending consumption dollars into the product market. The reverse direction sends goods and services back to households, while wages, rent, interest, and profit along with the resources land, labor, capital, and entrepreneurship move through the resource market, not the product market.

24. Why can nominal GDP rise from one year to the next even if the economy produced no additional physical output?
    • Because nominal GDP is adjusted to remove the effect of price changes
    • Because the population grew during the year
    • Because nominal GDP values output at current prices, so higher prices alone increase it
    • Because imports were subtracted from total spending

    Correct answer: Because nominal GDP values output at current prices, so higher prices alone increase it

    Nominal GDP can rise without more physical output because it values output at current prices, so rising prices alone increase its dollar value. Since nominal GDP is not adjusted for inflation, an increase may reflect higher prices, more output, or both. Real GDP is the measure that removes price effects, population growth does not directly raise the dollar value of output, and subtracting imports lowers rather than raises the total.

25. Which statement best describes why the aggregate demand curve slopes downward?
    • A lower price level raises the real value of wealth, lowers interest rates, and makes domestic goods cheaper relative to foreign goods, increasing the quantity of real output demanded
    • Higher prices encourage firms to supply more output along the curve
    • A lower price level reduces the cost of inputs for producers
    • Higher incomes shift the entire curve to the right

    Correct answer: A lower price level raises the real value of wealth, lowers interest rates, and makes domestic goods cheaper relative to foreign goods, increasing the quantity of real output demanded

    The aggregate demand curve slopes downward because a lower price level raises the real value of wealth, pushes interest rates down, and makes domestic goods relatively cheaper than foreign goods, all of which increase the quantity of real output demanded. These are the wealth effect, the interest-rate effect, and the net-export effect. Producer behavior describes aggregate supply, lower input costs relate to supply shifts, and higher incomes shift the whole curve rather than explaining its slope.

26. Which of the following would shift the aggregate demand curve to the right?
    • A decrease in consumer confidence about the future
    • An increase in government spending on infrastructure
    • An increase in the price level of domestic goods
    • A rise in interest rates that discourages borrowing

    Correct answer: An increase in government spending on infrastructure

    An increase in government spending on infrastructure shifts the aggregate demand curve to the right because government purchases are a component of aggregate demand, and more of it raises total spending at every price level. Falling consumer confidence and higher interest rates reduce spending and shift the curve left, while a change in the price level causes a movement along the curve rather than a shift of it.

27. An economy has a marginal propensity to consume of 0.8. What is the value of the spending multiplier?
    • 1.25
    • 8
    • 5
    • 0.2

    Correct answer: 5

    The spending multiplier is 5. The spending multiplier equals 1 divided by 1 minus the marginal propensity to consume, which is the same as 1 divided by the marginal propensity to save. With a marginal propensity to consume of 0.8, the marginal propensity to save is 0.2, and 1 divided by 0.2 equals 5. The value 1.25 comes from using 0.8 directly as a denominator, and 0.2 is the marginal propensity to save itself.

28. If households spend 75 cents of every additional dollar of disposable income, what is the marginal propensity to save?
    • 0.75
    • 0.40
    • 1.75
    • 0.25

    Correct answer: 0.25

    The marginal propensity to save is 0.25. The marginal propensity to consume and the marginal propensity to save always sum to 1, because each additional dollar of disposable income is either spent or saved. If 75 cents of each dollar is consumed, the marginal propensity to consume is 0.75, leaving 0.25 to be saved. The value 0.75 is the propensity to consume, not the propensity to save.

29. An economy with a marginal propensity to consume of 0.9 experiences an initial increase in investment spending of $20 billion. By how much will real GDP ultimately change, assuming a simple closed economy with no taxes?
    • $20 billion
    • $180 billion
    • $200 billion
    • $22 billion

    Correct answer: $200 billion

    Real GDP will ultimately rise by $200 billion. The total change equals the initial spending change multiplied by the spending multiplier, which is 1 divided by 1 minus the marginal propensity to consume. With a marginal propensity to consume of 0.9, the multiplier is 1 divided by 0.1, or 10, and $20 billion times 10 equals $200 billion. The $180 billion figure leaves out the initial round of spending, and $20 billion ignores the multiplier altogether.

30. What is the underlying reason an initial change in spending leads to a larger total change in real GDP through the multiplier effect?
    • Because prices automatically rise to amplify the original spending
    • Because one person's spending becomes another person's income, which is then partly spent again in successive rounds
    • Because the government always matches private spending dollar for dollar
    • Because banks are required to lend out all new deposits immediately

    Correct answer: Because one person's spending becomes another person's income, which is then partly spent again in successive rounds

    The multiplier effect occurs because one person's spending becomes another person's income, and that income is partly spent again, creating successive rounds of new spending throughout the economy. Each round is smaller than the last because some income is saved, but the rounds add up to a total change larger than the initial injection. Automatic price changes, government matching, and bank lending requirements are not the mechanism behind the spending multiplier.

31. Which determinant would shift the short-run aggregate supply curve to the left?
    • A decrease in the prices of key raw materials such as oil
    • An increase in worker productivity
    • A sharp increase in nominal wages across the economy
    • An increase in business subsidies

    Correct answer: A sharp increase in nominal wages across the economy

    A sharp increase in nominal wages across the economy shifts the short-run aggregate supply curve to the left because higher wages raise per-unit production costs, reducing the quantity firms are willing to supply at each price level. Lower raw-material prices, higher productivity, and increased subsidies all lower production costs or raise output, shifting short-run aggregate supply to the right instead.

32. What does the long-run aggregate supply curve represent in the AD-AS model?
    • The level of output at the economy's full-employment or potential level, independent of the price level
    • The positive relationship between the price level and output in the short run
    • The total spending in the economy at each price level
    • The maximum output that can be produced only during an expansion

    Correct answer: The level of output at the economy's full-employment or potential level, independent of the price level

    The long-run aggregate supply curve represents output at the economy's full-employment or potential level and is vertical, meaning that level of output is independent of the price level. In the long run, wages and prices fully adjust, so the economy produces at potential regardless of the price level. A positive price-output relationship describes short-run aggregate supply, total spending describes aggregate demand, and potential output is not limited to expansions.

33. An economy is producing at a short-run equilibrium level of real GDP that is below its full-employment level of output. This situation is best described as which of the following?
    • An inflationary gap
    • Long-run equilibrium
    • A budget surplus
    • A recessionary gap

    Correct answer: A recessionary gap

    Producing below full-employment output is a recessionary gap, the amount by which real GDP falls short of potential output. A recessionary gap is associated with higher cyclical unemployment and downward pressure on prices over time. An inflationary gap occurs when output exceeds potential, long-run equilibrium happens when output equals potential, and a budget surplus is a fiscal concept rather than an output gap.

34. When short-run equilibrium real GDP exceeds the full-employment level of output, the economy is experiencing which condition?
    • A recessionary gap
    • Structural unemployment
    • A liquidity trap
    • An inflationary gap

    Correct answer: An inflationary gap

    When real GDP exceeds full-employment output, the economy has an inflationary gap, the amount by which actual output rises above potential. Producing beyond potential strains resources and places upward pressure on the price level. A recessionary gap is the opposite case of output below potential, structural unemployment relates to skill mismatches, and a liquidity trap is a monetary-policy phenomenon, not an output gap.

35. An economy's potential output is $800 billion, but its current real GDP is $760 billion. What is the size and type of the output gap?
    • A $40 billion inflationary gap
    • A $760 billion output gap
    • A $40 billion recessionary gap
    • A $1,560 billion inflationary gap

    Correct answer: A $40 billion recessionary gap

    The economy has a $40 billion recessionary gap. The output gap is the difference between actual real GDP and potential output, and here $760 billion minus $800 billion equals negative $40 billion, meaning output falls $40 billion short of potential. Because actual output is below potential, the gap is recessionary rather than inflationary. Adding the two figures or treating actual GDP itself as the gap produces the incorrect answers.

36. Which combination of actions represents expansionary fiscal policy?
    • Increasing government spending and cutting taxes
    • Decreasing government spending and raising taxes
    • Raising the required reserve ratio and selling bonds
    • Lowering the discount rate and buying bonds

    Correct answer: Increasing government spending and cutting taxes

    Increasing government spending and cutting taxes represents expansionary fiscal policy, which aims to raise aggregate demand and close a recessionary gap. Both actions put more spending power into the economy. Decreasing spending and raising taxes is contractionary fiscal policy, while changing the reserve ratio, the discount rate, or buying and selling bonds are monetary-policy tools used by the central bank, not fiscal policy.

37. A government wants to close a recessionary gap using fiscal policy. If the marginal propensity to consume is 0.75, how much should government spending increase to raise real GDP by $120 billion?
    • $120 billion
    • $90 billion
    • $480 billion
    • $30 billion

    Correct answer: $30 billion

    Government spending should increase by $30 billion. The spending multiplier is 1 divided by 1 minus the marginal propensity to consume, which is 1 divided by 0.25, or 4. To raise real GDP by $120 billion, the required initial spending equals the desired change divided by the multiplier, so $120 billion divided by 4 equals $30 billion. Spending the full $120 billion ignores the multiplier, and $480 billion multiplies instead of divides.

38. In the aggregate demand-aggregate supply model, an increase in aggregate demand while the economy is on the upward-sloping portion of the short-run aggregate supply curve will most likely cause what?
    • A decrease in both the price level and real output
    • An increase in the price level and a decrease in real output
    • An increase in the price level and an increase in real output
    • No change in either the price level or real output

    Correct answer: An increase in the price level and an increase in real output

    An increase in aggregate demand along the upward-sloping short-run aggregate supply curve raises both the price level and real output. As total spending rises, firms respond by increasing production and raising prices. A simultaneous fall in both would require a leftward demand shift, the combination of higher prices and lower output reflects a negative supply shock, and the model predicts a clear change rather than no change.

39. The marginal propensity to consume is best defined as which of the following?
    • The total amount of income a household spends on consumption
    • The fraction of total income that is saved each year
    • The fraction of each additional dollar of disposable income that is spent on consumption
    • The ratio of consumption to investment in the economy

    Correct answer: The fraction of each additional dollar of disposable income that is spent on consumption

    The marginal propensity to consume is the fraction of each additional dollar of disposable income that is spent on consumption. It measures how spending changes in response to a change in income, which is why it drives the size of the spending multiplier. Total consumption spending is a level rather than a marginal concept, the fraction saved is the marginal propensity to save, and the consumption-to-investment ratio is unrelated.

40. A negative supply shock, such as a sudden spike in global oil prices, would most likely have which effect in the short run?
    • Shift short-run aggregate supply left, raising the price level and lowering real output
    • Shift short-run aggregate supply right, lowering the price level and raising real output
    • Shift aggregate demand right, raising both prices and output
    • Leave the AD-AS equilibrium completely unchanged

    Correct answer: Shift short-run aggregate supply left, raising the price level and lowering real output

    A negative supply shock like a spike in oil prices shifts short-run aggregate supply to the left, raising the price level while lowering real output. Higher input costs reduce the quantity firms supply at every price level, producing both higher prices and falling output at once. A rightward supply shift would result from lower costs, a demand shift would not capture rising costs, and the shock clearly changes the equilibrium.

41. Why is the long-run aggregate supply curve drawn as a vertical line?
    • Because in the long run all input prices, including wages, adjust so that output returns to its full-employment level regardless of the price level
    • Because firms cannot change output once prices are set
    • Because aggregate demand has no effect on the economy in the long run or short run
    • Because the price level is fixed in the long run

    Correct answer: Because in the long run all input prices, including wages, adjust so that output returns to its full-employment level regardless of the price level

    The long-run aggregate supply curve is vertical because in the long run all input prices, including wages, fully adjust, so the economy returns to its full-employment level of output regardless of the price level. Once costs adjust, changes in the price level no longer affect the quantity of real output produced. Firms can change output in the short run, aggregate demand does affect the short run, and the price level is not fixed in the long run.

42. To combat an inflationary gap, which contractionary fiscal policy action would be appropriate?
    • Increasing transfer payments to households
    • Reducing government spending
    • Cutting personal income tax rates
    • Increasing spending on public works projects

    Correct answer: Reducing government spending

    Reducing government spending is an appropriate contractionary fiscal policy to combat an inflationary gap, because lower government purchases decrease aggregate demand and ease upward pressure on the price level. Increasing transfer payments, cutting income taxes, and boosting public works all raise aggregate demand, which would worsen an inflationary gap rather than close it.

43. If an economy's marginal propensity to save is 0.4, what is the value of the spending multiplier?
    • 0.6
    • 2.5
    • 1.67
    • 4

    Correct answer: 2.5

    The spending multiplier is 2.5. The spending multiplier equals 1 divided by the marginal propensity to save, so 1 divided by 0.4 equals 2.5. A marginal propensity to save of 0.4 implies a marginal propensity to consume of 0.6, but the multiplier uses the saving figure in the denominator directly. Using 0.6 in the denominator gives the incorrect 1.67, and 0.6 itself is the propensity to consume.

44. Starting from long-run equilibrium, a sharp decline in business and consumer confidence reduces aggregate demand. In the short run, what happens to the price level and real output?
    • Both the price level and real output rise
    • The price level rises while real output falls
    • The price level falls while real output rises
    • Both the price level and real output fall, opening a recessionary gap

    Correct answer: Both the price level and real output fall, opening a recessionary gap

    A decline in aggregate demand causes both the price level and real output to fall in the short run, opening a recessionary gap as output drops below potential. Less total spending means firms sell less and cut both prices and production. Rising values would require an increase in demand, and the mixed combinations describe supply shocks rather than a leftward shift in aggregate demand.

45. When the economy is producing beyond its full-employment output in the short run, what self-correcting adjustment tends to occur over time without policy intervention?
    • Aggregate demand automatically shifts right to sustain the higher output
    • The long-run aggregate supply curve shifts left to meet the higher output
    • Nominal wages and input costs rise, shifting short-run aggregate supply left until output returns to potential
    • The price level falls until output rises even further above potential

    Correct answer: Nominal wages and input costs rise, shifting short-run aggregate supply left until output returns to potential

    When output exceeds potential, an inflationary gap puts upward pressure on nominal wages and input costs, and as those costs rise the short-run aggregate supply curve shifts left until output returns to its full-employment level. This is the economy's self-correcting mechanism. Aggregate demand does not automatically rise, the long-run aggregate supply curve reflects potential and does not chase the gap, and prices rise rather than fall during this adjustment.

46. Which of the following is a component of aggregate demand in the AD-AS model?
    • The wages paid to workers in the resource market
    • The reserve requirement set by the central bank
    • The natural rate of unemployment
    • Net exports, equal to exports minus imports

    Correct answer: Net exports, equal to exports minus imports

    Net exports, equal to exports minus imports, is a component of aggregate demand, which consists of consumption, investment, government spending, and net exports. These four categories of spending together make up total demand for an economy's output at each price level. Wages are factor payments, the reserve requirement is a monetary tool, and the natural rate of unemployment is a labor-market concept, so none of them are components of aggregate demand.

47. A change in taxes generally has a smaller effect on real GDP than an equal-sized change in government spending. What is the main reason for this difference?
    • Taxes never affect consumer spending at all
    • Government spending is always financed by borrowing while tax cuts are not
    • The tax multiplier is larger than the spending multiplier
    • Part of any tax cut is saved rather than spent, so the first round of new spending is smaller

    Correct answer: Part of any tax cut is saved rather than spent, so the first round of new spending is smaller

    A tax change has a smaller effect because part of any tax cut is saved rather than spent, so the first round of new spending is smaller than with direct government spending. Government spending enters the economy fully in the first round, but a tax cut only boosts demand by the portion households choose to consume. Tax cuts do affect spending, financing method is not the reason, and the tax multiplier is smaller in magnitude than the spending multiplier.

48. An increase in worker productivity that lowers per-unit production costs across the economy would have which effect on aggregate supply?
    • It shifts both short-run and long-run aggregate supply to the right
    • It shifts short-run aggregate supply to the left only
    • It shifts aggregate demand to the left
    • It causes a movement along the short-run aggregate supply curve only

    Correct answer: It shifts both short-run and long-run aggregate supply to the right

    An increase in worker productivity shifts both short-run and long-run aggregate supply to the right, because greater productivity lowers per-unit costs and raises the economy's potential output. Higher productivity expands what the economy can produce at full employment, moving the long-run curve, while also lowering costs in the short run. It does not shift supply left, does not affect aggregate demand directly, and is a shift rather than a movement along the curve.

49. In the aggregate demand-aggregate supply model, the economy is in long-run equilibrium when which of the following is true?
    • Aggregate demand intersects short-run aggregate supply at a point on the long-run aggregate supply curve, with output at potential
    • Aggregate demand intersects short-run aggregate supply to the right of potential output
    • Real output is below the full-employment level
    • The price level is at its lowest possible value

    Correct answer: Aggregate demand intersects short-run aggregate supply at a point on the long-run aggregate supply curve, with output at potential

    Long-run equilibrium occurs when aggregate demand intersects short-run aggregate supply at a point that lies on the long-run aggregate supply curve, so real output equals potential output. At this point there is no recessionary or inflationary gap and no pressure for wages or prices to adjust further. Equilibrium to the right of potential is an inflationary gap, output below full employment is a recessionary gap, and the lowest price level is not a condition for long-run equilibrium.

50. Suppose the marginal propensity to consume rises from 0.6 to 0.8. What happens to the value of the spending multiplier?
    • It stays the same because the multiplier does not depend on the marginal propensity to consume
    • It increases from 2.5 to 5
    • It decreases from 5 to 2.5
    • It falls because a higher propensity to consume reduces spending rounds

    Correct answer: It increases from 2.5 to 5

    The spending multiplier increases from 2.5 to 5. With a marginal propensity to consume of 0.6, the multiplier is 1 divided by 0.4, or 2.5, and with 0.8 it becomes 1 divided by 0.2, or 5. A higher marginal propensity to consume means more of each dollar is re-spent in successive rounds, which strengthens the multiplier rather than weakening it or leaving it unchanged.

51. Which of the following lists the three primary functions of money in an economy?
    • Medium of exchange, unit of account, and store of value
    • Reserve requirement, discount rate, and open market operations
    • Currency, demand deposits, and savings accounts
    • Consumption, investment, and government spending

    Correct answer: Medium of exchange, unit of account, and store of value

    The three functions of money are medium of exchange, unit of account, and store of value. Money serves as a medium of exchange by being widely accepted in transactions, as a unit of account by providing a common measure of value, and as a store of value by holding purchasing power over time. The reserve requirement and discount rate are monetary policy tools, the currency-and-deposits list describes measures of money rather than its functions, and consumption and investment are components of aggregate demand.

52. When a price tag lists a backpack as costing $40, which function of money is being demonstrated?
    • Store of value
    • Medium of exchange
    • Unit of account
    • Fractional reserve

    Correct answer: Unit of account

    Listing the backpack's price as $40 demonstrates money's function as a unit of account, because money provides a common measuring stick that lets goods be priced and compared in the same terms. Store of value refers to holding purchasing power for later, medium of exchange refers to actually using money to complete a purchase, and fractional reserve is a banking practice rather than a function of money.

53. In the United States measures of the money supply, which of the following is included in M1 but not counted as part of the narrow definition of currency in circulation?
    • Large-denomination time deposits
    • Stocks held in brokerage accounts
    • Corporate bonds
    • Checkable demand deposits

    Correct answer: Checkable demand deposits

    Checkable demand deposits are included in M1 but are not physical currency in circulation. M1 consists of the most liquid forms of money, including currency held by the public and checkable deposits that can be spent quickly. Large-denomination time deposits are far less liquid and fall outside M1, while stocks and corporate bonds are financial assets that are not classified as money at all.

54. How does the broader money measure M2 differ from M1?
    • M2 includes only physical currency, while M1 includes deposits
    • M2 excludes checkable deposits that are part of M1
    • M2 includes everything in M1 plus less liquid assets such as savings deposits and small time deposits
    • M2 measures only the reserves banks hold at the central bank

    Correct answer: M2 includes everything in M1 plus less liquid assets such as savings deposits and small time deposits

    M2 includes everything in M1 plus additional, less liquid assets such as savings deposits and small-denomination time deposits. Because M2 adds near-money that is not as easily spent as the items in M1, it is a broader measure of the money supply. M2 does not exclude currency or the checkable deposits found in M1, and it is not limited to bank reserves held at the central bank.

55. In a fractional reserve banking system, what does a bank do with the portion of deposits it is not required to hold as reserves?
    • It keeps all of it locked in the vault as excess reserves indefinitely
    • It sends it to the central bank to be destroyed
    • It converts it into government bonds it is required to buy
    • It lends it out, which creates new money in the banking system

    Correct answer: It lends it out, which creates new money in the banking system

    Under fractional reserve banking, a bank lends out the portion of deposits it is not required to keep as reserves, and this lending creates new money in the banking system. When the loaned funds are deposited again, they support still more lending, expanding the money supply. Banks do not hold all deposits idle, deposits are not sent to the central bank to be destroyed, and banks are not required to convert excess funds into government bonds.

56. Which feature most directly distinguishes a fractional reserve banking system from a system of full reserve banking?
    • Banks keep only a fraction of deposits on hand and lend out the rest
    • Banks are prohibited from accepting any new deposits
    • Banks must hold the entire amount of every deposit in reserve
    • Banks are not allowed to charge interest on loans

    Correct answer: Banks keep only a fraction of deposits on hand and lend out the rest

    A fractional reserve system is defined by banks keeping only a fraction of deposits on hand as reserves and lending out the rest. This lending is what allows the banking system to expand the money supply beyond the original deposits. Full reserve banking would require holding the entire amount of every deposit, accepting deposits is central to banking, and charging interest is permitted in both systems.

57. If the required reserve ratio is 20 percent, what is the value of the simple money multiplier?
    • 20
    • 0.2
    • 5
    • 2

    Correct answer: 5

    The simple money multiplier is 5. The money multiplier equals 1 divided by the required reserve ratio, so 1 divided by 0.20 equals 5. This means that, in the best case, a new deposit can ultimately increase the money supply by up to five times its amount. The value 0.2 is the reserve ratio itself, and 20 confuses the percentage with the multiplier.

58. A bank receives a new deposit of $1,000 and the required reserve ratio is 10 percent. Assuming banks lend all excess reserves and all loaned funds are redeposited, by how much can the money supply ultimately increase from this deposit?
    • $1,000
    • $900
    • $10,000
    • $100

    Correct answer: $10,000

    The money supply can ultimately increase by up to $10,000. The maximum expansion equals the initial deposit multiplied by the money multiplier, which is 1 divided by the required reserve ratio. With a reserve ratio of 10 percent the multiplier is 10, and $1,000 times 10 equals $10,000. The figure $900 is only the first loan from the initial deposit, and $1,000 ignores the multiplier process entirely.

59. A bank holds $50,000 in checkable deposits and the required reserve ratio is 12 percent. How much must the bank hold in required reserves?
    • $6,000
    • $44,000
    • $600
    • $12,000

    Correct answer: $6,000

    The bank must hold $6,000 in required reserves. Required reserves equal the required reserve ratio multiplied by checkable deposits, so 0.12 times $50,000 equals $6,000. The remaining $44,000 represents the deposits not required to be held, which can support lending, and $600 results from misplacing a decimal in the calculation.

60. How does lowering the required reserve ratio affect a bank's ability to create money?
    • It forces banks to hold more deposits idle, reducing lending
    • It increases the money multiplier and allows more loans from a given deposit
    • It has no effect on the amount banks can lend
    • It decreases the money multiplier and shrinks lending capacity

    Correct answer: It increases the money multiplier and allows more loans from a given deposit

    Lowering the required reserve ratio increases the money multiplier and allows banks to make more loans from a given deposit. A smaller ratio means banks must keep less of each deposit in reserve, freeing more funds to lend and expanding the money supply more strongly. A lower ratio does not force banks to hold more idle deposits, does leave the lending capacity unchanged, and raises rather than lowers the multiplier.

61. In the money market model, the money supply curve is typically drawn as a vertical line. What does this shape imply?
    • The quantity of money supplied rises automatically as interest rates increase
    • The central bank sets the quantity of money independently of the interest rate
    • The money supply depends entirely on household saving decisions
    • The money supply falls as the price level rises

    Correct answer: The central bank sets the quantity of money independently of the interest rate

    A vertical money supply curve implies that the central bank sets the quantity of money independently of the interest rate. Because the monetary authority controls the money supply directly, the quantity offered does not change as the interest rate changes, producing a vertical line. The supply does not rise automatically with interest rates, is not determined by household saving, and is not driven down by a higher price level in this model.

62. In the money market, if the central bank increases the money supply while money demand is unchanged, what happens to the nominal interest rate?
    • It rises as the supply curve shifts left
    • It stays the same because the interest rate is fixed
    • It falls as the supply curve shifts right
    • It rises because money demand increases

    Correct answer: It falls as the supply curve shifts right

    An increase in the money supply with unchanged demand causes the nominal interest rate to fall as the vertical money supply curve shifts to the right. At the original interest rate there is now a surplus of money, which pushes the equilibrium interest rate down until the quantity demanded again equals the larger supply. An increase in supply shifts the curve right, not left, the interest rate is not fixed, and money demand does not rise on its own here.

63. Which set of actions describes expansionary monetary policy carried out by a central bank?
    • Selling government bonds, raising the discount rate, and raising the reserve requirement
    • Increasing income taxes and reducing government spending
    • Lowering income taxes and increasing transfer payments
    • Buying government bonds, lowering the discount rate, and lowering the reserve requirement

    Correct answer: Buying government bonds, lowering the discount rate, and lowering the reserve requirement

    Expansionary monetary policy involves buying government bonds, lowering the discount rate, and lowering the reserve requirement, all of which increase the money supply and lower interest rates to stimulate borrowing and spending. Selling bonds and raising the discount rate and reserve requirement are contractionary. Changing income taxes, government spending, and transfer payments are fiscal policy actions, not monetary policy.

64. A central bank is concerned about high inflation and wants to slow the economy. Which monetary policy action is most consistent with that goal?
    • Reducing the reserve requirement to encourage lending
    • Lowering the discount rate to make borrowing cheaper
    • Increasing government spending on public projects
    • Selling government bonds to reduce the money supply and raise interest rates

    Correct answer: Selling government bonds to reduce the money supply and raise interest rates

    Selling government bonds to reduce the money supply and raise interest rates is contractionary monetary policy, the appropriate tool for slowing an economy facing high inflation. Higher interest rates discourage borrowing and spending, easing upward pressure on prices. Reducing the reserve requirement and lowering the discount rate are expansionary actions that would worsen inflation, and changing government spending is fiscal rather than monetary policy.

65. Through what mechanism does expansionary monetary policy ultimately affect real GDP in the short run?
    • Increasing the money supply lowers interest rates, which raises investment and consumption, shifting aggregate demand right
    • Increasing the money supply directly shifts long-run aggregate supply to the right
    • Raising interest rates encourages firms to borrow and invest more
    • Reducing the money supply lowers interest rates and boosts spending

    Correct answer: Increasing the money supply lowers interest rates, which raises investment and consumption, shifting aggregate demand right

    Expansionary monetary policy works by increasing the money supply, which lowers interest rates and makes borrowing cheaper, raising interest-sensitive investment and consumption and shifting aggregate demand to the right. The result is higher real output in the short run. Monetary policy operates on aggregate demand rather than directly shifting long-run aggregate supply, higher interest rates discourage rather than encourage borrowing, and reducing the money supply raises rather than lowers interest rates.

66. Open market operations, the most commonly used tool of monetary policy, refer to which central bank activity?
    • Setting the maximum interest rate banks may charge borrowers
    • Buying and selling government bonds to change the money supply
    • Printing currency to directly pay government bills
    • Requiring banks to hold a fixed percentage of deposits in reserve

    Correct answer: Buying and selling government bonds to change the money supply

    Open market operations are the central bank's buying and selling of government bonds to change the money supply. Buying bonds injects reserves into the banking system and expands the money supply, while selling bonds withdraws reserves and contracts it. Setting a ceiling on loan rates is not open market activity, printing currency to pay bills is not how the tool works, and requiring a reserve percentage is the reserve requirement rather than open market operations.

67. When a central bank buys government bonds from banks through open market operations, what is the immediate effect on bank reserves and the money supply?
    • Bank reserves fall and the money supply contracts
    • Bank reserves are unchanged and only interest rates fall
    • Bank reserves rise but the money supply contracts
    • Bank reserves rise and the money supply expands

    Correct answer: Bank reserves rise and the money supply expands

    When the central bank buys government bonds, it pays banks for the bonds, so bank reserves rise and the money supply expands. The new reserves give banks more funds to lend, which multiplies through the banking system and increases the money supply. Buying bonds does not reduce reserves or contract the money supply, and reserves clearly change rather than staying fixed.

68. The loanable funds market brings together which two groups to determine the real interest rate?
    • Importers who demand foreign currency and exporters who supply it
    • The central bank that supplies money and households that demand it
    • Firms that supply goods and consumers who demand them
    • Savers who supply funds and borrowers who demand funds for investment

    Correct answer: Savers who supply funds and borrowers who demand funds for investment

    The loanable funds market brings together savers, who supply funds, and borrowers, who demand funds for investment, and their interaction determines the real interest rate. The supply of loanable funds comes from saving, while the demand comes from the desire to borrow for investment projects. The other choices describe the foreign exchange market, the money market, and the product market rather than the loanable funds market.

69. In the loanable funds market, an increase in private saving by households would have which effect, holding other factors constant?
    • The supply of loanable funds increases and the real interest rate falls
    • The demand for loanable funds increases and the real interest rate rises
    • The supply of loanable funds decreases and the real interest rate rises
    • Both supply and demand fall, leaving the interest rate unchanged

    Correct answer: The supply of loanable funds increases and the real interest rate falls

    An increase in private saving increases the supply of loanable funds, shifting the supply curve to the right and lowering the real interest rate. More available funds for lending puts downward pressure on the price of borrowing, which is the real interest rate, and the lower rate encourages more investment. Saving affects supply rather than demand, an increase raises rather than lowers supply, and the change clearly moves the interest rate.

70. A large increase in government budget deficits, financed by borrowing, is expected to have what effect in the loanable funds market?
    • It decreases the demand for loanable funds and lowers the real interest rate
    • It increases the demand for loanable funds and raises the real interest rate
    • It increases the supply of loanable funds and lowers the real interest rate
    • It leaves the loanable funds market completely unaffected

    Correct answer: It increases the demand for loanable funds and raises the real interest rate

    A larger government deficit financed by borrowing increases the demand for loanable funds, shifting demand to the right and raising the real interest rate. The government competes with private borrowers for the available pool of savings, pushing the real interest rate up. Government borrowing adds to demand rather than reducing it or adding to supply, and it clearly affects the market.

71. The quantity theory of money is most often expressed through which equation?
    • $GDP = C + I + G + X_n$
    • $M \times V = P \times Q$
    • $\text{Multiplier} = \frac{1}{1 - MPC}$
    • $\text{Unemployment rate} = \frac{\text{unemployed}}{\text{labor force}}$

    Correct answer: $M \times V = P \times Q$

    The quantity theory of money is expressed through the equation of exchange, $M \times V = P \times Q$, where M is the money supply, V is the velocity of money, P is the price level, and Q is real output. This relationship links the quantity of money to nominal spending in the economy. The first equation is the expenditure approach to GDP, the third is the spending multiplier, and the fourth is the unemployment rate formula.

72. According to the quantity theory of money, if velocity and real output are assumed constant, a 6 percent increase in the money supply will most likely cause what?
    • A 6 percent decrease in the price level
    • No change in the price level
    • A 6 percent increase in the price level
    • A 6 percent increase in real output

    Correct answer: A 6 percent increase in the price level

    If velocity and real output are constant, the quantity theory predicts that a 6 percent increase in the money supply causes a 6 percent increase in the price level. In the equation $M \times V = P \times Q$, holding V and Q fixed means changes in M translate directly into proportional changes in P. The money increase raises rather than lowers prices, does change the price level, and does not affect real output when output is assumed constant.

73. In the equation of exchange used in the quantity theory of money, what does the variable V represent?
    • The velocity of money, or the average number of times a unit of money is spent in a period
    • The total volume of goods imported during the year
    • The variable cost of producing additional output
    • The value of government bonds held by banks

    Correct answer: The velocity of money, or the average number of times a unit of money is spent in a period

    In the equation of exchange, V represents the velocity of money, the average number of times a unit of money is spent on final goods and services during a period. Velocity links the money supply to the level of nominal spending, since the same dollars can be used in many transactions. V is not import volume, variable cost, or the value of bonds held by banks.

74. An economy has only frictional and structural changes and the central bank announces it will keep the money supply fixed. Which factor would still cause the nominal interest rate in the money market to rise?
    • A decrease in real GDP that reduces transactions
    • An increase in real GDP that raises money demand for transactions
    • A fall in the price level that reduces money demand
    • A central bank purchase of government bonds

    Correct answer: An increase in real GDP that raises money demand for transactions

    With the money supply fixed, an increase in real GDP raises money demand for transactions, shifting the money demand curve right and pushing the nominal interest rate up. As output and incomes rise, people need more money to carry out a greater volume of transactions, increasing demand against a fixed supply. A decrease in real GDP or a falling price level would reduce money demand, and a central bank bond purchase would increase the money supply rather than leave it fixed.

75. Why is the actual increase in the money supply from a new deposit often smaller than the maximum predicted by the simple money multiplier?
    • Because the central bank automatically reverses every new loan
    • Because banks may hold excess reserves and borrowers may hold some funds as cash rather than redepositing them
    • Because the required reserve ratio is always greater than 100 percent
    • Because loans are never redeposited into any bank

    Correct answer: Because banks may hold excess reserves and borrowers may hold some funds as cash rather than redepositing them

    The actual money expansion is often smaller than the maximum because banks may choose to hold excess reserves and the public may hold some loaned funds as cash rather than redepositing all of it. Both leakages reduce the funds available for further lending, weakening the multiplier process. The central bank does not automatically reverse loans, the reserve ratio cannot exceed 100 percent, and loans are frequently redeposited rather than never.

76. Which statement correctly contrasts what is determined in the money market versus the loanable funds market in the AP Macroeconomics framework?
    • Both markets determine the exchange rate between currencies
    • The money market determines the nominal interest rate, while the loanable funds market determines the real interest rate
    • The money market determines the real interest rate, while the loanable funds market determines the price level
    • Both markets determine the level of required reserves

    Correct answer: The money market determines the nominal interest rate, while the loanable funds market determines the real interest rate

    In the standard framework, the money market determines the nominal interest rate through the interaction of money supply and money demand, while the loanable funds market determines the real interest rate through the interaction of saving and borrowing for investment. Neither market sets the exchange rate or the level of required reserves, and the money market is associated with the nominal rate rather than the real rate.

77. A worker decides to keep part of her paycheck in cash so she can use its purchasing power for a purchase several months from now. Which function of money does this choice rely on?
    • Unit of account
    • Medium of exchange
    • Store of value
    • Reserve requirement

    Correct answer: Store of value

    Holding cash to preserve purchasing power for a future purchase relies on money's function as a store of value. A store of value lets people set money aside today and use it to buy goods later because it retains its worth over time. Unit of account refers to pricing goods in common terms, medium of exchange refers to using money to complete a transaction, and the reserve requirement is a banking rule rather than a function of money.

78. The short-run Phillips curve illustrates which relationship between two macroeconomic variables?
    • An inverse relationship between the inflation rate and the unemployment rate
    • A direct, positive relationship between inflation and unemployment
    • A direct relationship between real GDP and the price level
    • An inverse relationship between interest rates and investment

    Correct answer: An inverse relationship between the inflation rate and the unemployment rate

    The short-run Phillips curve shows an inverse relationship between the inflation rate and the unemployment rate, meaning that in the short run lower unemployment tends to be associated with higher inflation. This tradeoff mirrors the short-run aggregate supply relationship, where increases in aggregate demand push output and the price level up while pulling unemployment down.

79. What does the long-run Phillips curve look like, and what does that shape represent?
    • It is vertical at the natural rate of unemployment, showing no permanent inflation-unemployment tradeoff
    • It is downward sloping, showing a permanent tradeoff between inflation and unemployment
    • It is horizontal at zero inflation, showing price stability at all unemployment rates
    • It is upward sloping, showing that higher inflation causes higher unemployment

    Correct answer: It is vertical at the natural rate of unemployment, showing no permanent inflation-unemployment tradeoff

    The long-run Phillips curve is vertical at the natural rate of unemployment, indicating there is no permanent tradeoff between inflation and unemployment. In the long run the economy returns to its natural rate of unemployment regardless of the inflation rate, just as long-run aggregate supply is vertical at potential output.

80. An economy experiences a severe negative supply shock when world oil prices spike sharply. Which combination of conditions, known as stagflation, is most likely to result in the short run?
    • Rising prices together with rising unemployment
    • Falling prices together with falling unemployment
    • Rising prices together with falling unemployment
    • Falling prices together with rising output

    Correct answer: Rising prices together with rising unemployment

    Stagflation is the combination of rising prices and rising unemployment occurring together, which is exactly what a negative supply shock such as an oil price spike produces. The shock shifts short-run aggregate supply left, raising the price level while reducing output and increasing unemployment.

81. A large increase in government deficit spending raises the demand for loanable funds and pushes up real interest rates, leading firms to reduce their investment. This reduction in private investment caused by government borrowing is known as what?
    • The crowding-out effect
    • The multiplier effect
    • The wealth effect
    • Automatic stabilization

    Correct answer: The crowding-out effect

    The crowding-out effect occurs when government borrowing to finance a deficit raises real interest rates and thereby reduces private investment spending. Because higher interest rates discourage firms from borrowing to invest, the expansionary impact of the deficit spending is partly offset.

82. In the AD-AS model, long-run economic growth is best represented by which of the following?
    • A rightward shift of the long-run aggregate supply curve
    • A leftward shift of the aggregate demand curve
    • A movement up along the short-run aggregate supply curve
    • A leftward shift of the short-run aggregate supply curve

    Correct answer: A rightward shift of the long-run aggregate supply curve

    Long-run economic growth is shown as a rightward shift of the long-run aggregate supply curve, reflecting an increase in the economy's potential output. This corresponds to an outward shift of the production possibilities curve and results from gains in the quantity or quality of resources and improvements in technology.

83. Which of the following would shift an economy's long-run aggregate supply curve to the right, increasing potential output?
    • An increase in the economy's capital stock and labor productivity
    • A temporary increase in consumer confidence and spending
    • A decrease in the money supply by the central bank
    • A short-term reduction in oil prices

    Correct answer: An increase in the economy's capital stock and labor productivity

    An increase in the capital stock and labor productivity shifts long-run aggregate supply to the right because it raises the economy's productive capacity. Such growth in the quantity and quality of resources, along with better technology, is what permanently expands potential output, unlike temporary demand changes.

84. According to the standard model, the long-run Phillips curve is positioned at which point on the horizontal axis?
    • At the natural rate of unemployment
    • At a zero unemployment rate
    • At the cyclical unemployment rate
    • At the rate where inflation equals zero

    Correct answer: At the natural rate of unemployment

    The long-run Phillips curve is vertical and located at the natural rate of unemployment. This reflects the idea that, once expectations fully adjust, the economy gravitates to its natural rate regardless of the inflation rate, so there is no permanent inflation-unemployment tradeoff.

85. A central bank pursues expansionary monetary policy that increases aggregate demand. Along a stable short-run Phillips curve, what is the expected short-run effect?
    • Inflation rises and unemployment falls
    • Both inflation and unemployment fall
    • Inflation falls and unemployment rises
    • Both inflation and unemployment rise

    Correct answer: Inflation rises and unemployment falls

    An increase in aggregate demand moves the economy upward along a stable short-run Phillips curve, so inflation rises and unemployment falls. This is the short-run tradeoff captured by the curve, mirroring the rise in the price level and output that accompanies higher aggregate demand in the AD-AS model.

86. Which point on the short-run Phillips curve corresponds to the economy producing at its full-employment level of output?
    • The point where unemployment equals the natural rate
    • The point where unemployment is zero
    • The point where inflation is at its highest
    • The point where inflation is negative

    Correct answer: The point where unemployment equals the natural rate

    The economy is at full-employment output where the short-run Phillips curve intersects the long-run Phillips curve, which is the point where unemployment equals the natural rate. At that point there is no cyclical unemployment, corresponding to production at potential output in the AD-AS model.

87. A persistent negative supply shock shifts the short-run Phillips curve in which direction, and why is this consistent with stagflation?
    • Leftward, because lower costs reduce both inflation and unemployment
    • Rightward, because higher costs raise both inflation and unemployment
    • It does not shift; the economy simply moves along the curve
    • Downward, because the natural rate of unemployment falls

    Correct answer: Rightward, because higher costs raise both inflation and unemployment

    A negative supply shock shifts the short-run Phillips curve rightward (outward), so at any given unemployment rate inflation is higher. This produces stagflation because the economy faces higher inflation and higher unemployment simultaneously, the same outcome shown by a leftward shift of short-run aggregate supply.

88. How does the crowding-out effect reduce the long-run benefits of government deficit spending?
    • By lowering the price level and discouraging consumption
    • By raising real interest rates and reducing private investment, which slows capital accumulation
    • By increasing the money supply and causing hyperinflation
    • By shifting the long-run aggregate supply curve to the right

    Correct answer: By raising real interest rates and reducing private investment, which slows capital accumulation

    Crowding out reduces long-run benefits because the higher real interest rates from government borrowing decrease private investment, slowing the accumulation of capital. Since capital formation drives long-run growth, less investment today means a smaller capital stock and slower expansion of potential output.

89. Which of the following best explains why there is no permanent tradeoff between inflation and unemployment in the long run?
    • The government permanently fixes wages and prices
    • Workers and firms eventually adjust their expectations, returning unemployment to its natural rate
    • Inflation always equals zero in the long run
    • The natural rate of unemployment continually falls toward zero

    Correct answer: Workers and firms eventually adjust their expectations, returning unemployment to its natural rate

    There is no permanent tradeoff because workers and firms eventually adjust their inflation expectations, which returns the economy to the natural rate of unemployment. Once expectations catch up, higher inflation no longer reduces unemployment, which is why the long-run Phillips curve is vertical.

90. An economy's real GDP grows steadily year after year while its potential output also expands. Which single factor is most directly responsible for sustained increases in potential output?
    • Repeated increases in aggregate demand
    • Growth in the quantity and quality of productive resources and technology
    • Frequent changes in the price level
    • A permanently lower natural rate of unemployment created by monetary policy

    Correct answer: Growth in the quantity and quality of productive resources and technology

    Sustained increases in potential output come from growth in the quantity and quality of productive resources and improvements in technology. These supply-side gains shift long-run aggregate supply and the production possibilities curve outward, unlike demand or price-level changes that only move the economy in the short run.

91. In the 1970s, the United States experienced simultaneous high inflation and high unemployment. Why did this episode challenge the original idea of a stable Phillips curve tradeoff?
    • It showed inflation and unemployment always move in the same direction
    • It demonstrated that supply shocks can raise inflation and unemployment at the same time
    • It proved the long-run Phillips curve slopes downward
    • It confirmed that aggregate demand alone determines both variables

    Correct answer: It demonstrated that supply shocks can raise inflation and unemployment at the same time

    The 1970s stagflation challenged the stable tradeoff because it demonstrated that supply shocks can raise inflation and unemployment simultaneously. The original Phillips curve assumed demand-driven movements along a single curve, but a leftward shift of short-run aggregate supply shifts the curve itself, breaking the expected inverse relationship.

92. Which statement correctly distinguishes the short-run Phillips curve from the long-run Phillips curve?
    • Both are vertical at the natural rate of unemployment
    • The short-run curve is downward sloping while the long-run curve is vertical
    • The short-run curve is vertical while the long-run curve is downward sloping
    • Both are downward sloping with the same slope

    Correct answer: The short-run curve is downward sloping while the long-run curve is vertical

    The short-run Phillips curve is downward sloping, reflecting a temporary inflation-unemployment tradeoff, while the long-run Phillips curve is vertical at the natural rate. The vertical long-run curve shows that, once expectations adjust, attempts to lower unemployment below its natural rate only raise inflation.

93. A government runs large, persistent budget deficits over many years. According to the crowding-out concept, what is the likely long-run consequence for economic growth?
    • Faster growth because higher interest rates encourage saving
    • Slower growth because reduced private investment shrinks future capital formation
    • No effect on growth because deficits only affect the price level
    • Faster growth because the long-run aggregate supply curve shifts right

    Correct answer: Slower growth because reduced private investment shrinks future capital formation

    Persistent deficits tend to slow long-run growth because the higher real interest rates crowd out private investment, shrinking future capital formation. With less new capital, the economy's potential output expands more slowly than it otherwise would, so long-run aggregate supply grows less over time.

94. Starting from the natural rate of unemployment, an unexpected increase in aggregate demand pushes unemployment below the natural rate in the short run. According to the Phillips curve framework, what happens as expectations adjust over time?
    • Unemployment stays permanently below the natural rate with higher inflation
    • Unemployment returns to the natural rate and the economy moves to a higher short-run Phillips curve
    • Inflation falls back to its original level and unemployment stays low
    • The long-run Phillips curve shifts left

    Correct answer: Unemployment returns to the natural rate and the economy moves to a higher short-run Phillips curve

    As expectations adjust, unemployment returns to the natural rate and the economy ends up on a higher short-run Phillips curve, with higher expected inflation. The temporary gain in lower unemployment disappears, leaving only higher inflation, which is why the long-run curve is vertical at the natural rate.

95. Which of the following is an example of a positive supply shock that would shift the short-run Phillips curve to the left, improving the inflation-unemployment combination?
    • A sharp rise in the price of imported oil
    • An increase in government deficit spending
    • A large unexpected drop in input costs due to a sudden fall in energy prices
    • A surge in consumer confidence and spending

    Correct answer: A large unexpected drop in input costs due to a sudden fall in energy prices

    A sudden fall in energy prices is a positive supply shock that lowers production costs across the economy, shifting the short-run Phillips curve leftward. At every unemployment rate inflation is now lower, the favorable opposite of the stagflation produced by a negative supply shock.

96. Which of the following would NOT contribute to long-run economic growth as shown by a rightward shift of long-run aggregate supply?
    • An increase in the size and skill of the labor force
    • Advances in production technology
    • A one-time increase in government spending that raises aggregate demand
    • Greater investment in physical capital

    Correct answer: A one-time increase in government spending that raises aggregate demand

    A one-time increase in government spending raises aggregate demand but does not by itself shift long-run aggregate supply, so it does not generate sustained growth. Long-run growth requires supply-side gains such as a larger or more skilled labor force, better technology, and more physical capital.

97. Which scenario best illustrates the natural rate of unemployment in the context of the long-run Phillips curve?
    • The unemployment rate when the economy is in a deep recession
    • The unemployment rate of exactly zero percent
    • The unemployment rate that persists when the economy produces at its potential output
    • The unemployment rate during a period of hyperinflation

    Correct answer: The unemployment rate that persists when the economy produces at its potential output

    The natural rate of unemployment is the rate that persists when the economy is producing at its potential output, with no cyclical unemployment. This is the unemployment rate marked by the vertical long-run Phillips curve, consisting only of frictional and structural unemployment.

98. Suppose the central bank repeatedly increases the money supply to try to keep unemployment below the natural rate. According to the long-run Phillips curve, what is the ultimate result?
    • A permanently lower unemployment rate with stable inflation
    • A permanently higher level of real output and lower prices
    • Accelerating inflation with unemployment eventually back at the natural rate
    • A leftward shift of the long-run Phillips curve

    Correct answer: Accelerating inflation with unemployment eventually back at the natural rate

    Repeated attempts to hold unemployment below the natural rate produce accelerating inflation while unemployment eventually returns to the natural rate. Because the long-run Phillips curve is vertical, expansionary policy cannot permanently lower unemployment and instead only raises the inflation rate over time.

99. Which of the following best describes the relationship between the production possibilities curve and long-run economic growth?
    • Economic growth is shown by a movement to a point inside the production possibilities curve
    • Economic growth is shown by a movement along a fixed production possibilities curve
    • Economic growth is shown by an outward shift of the production possibilities curve
    • Economic growth has no relationship to the production possibilities curve

    Correct answer: Economic growth is shown by an outward shift of the production possibilities curve

    Long-run economic growth is shown by an outward shift of the production possibilities curve, indicating the economy can now produce more of both goods. This parallels a rightward shift of long-run aggregate supply, since both reflect an increase in the economy's productive capacity.

100. Why is government deficit-financed spending more likely to crowd out private investment when the economy is already near full employment?
     • Because interest rates fall, making borrowing cheaper for firms
     • Because the money supply automatically expands to meet demand
     • Because there is little idle capacity, so added borrowing strongly pushes up real interest rates
     • Because the natural rate of unemployment rises

     Correct answer: Because there is little idle capacity, so added borrowing strongly pushes up real interest rates

     Crowding out is stronger near full employment because there is little idle capacity, so the government's added borrowing competes hard for scarce loanable funds and strongly pushes up real interest rates. The higher rates then discourage private investment, offsetting much of the spending's expansionary effect.

101. The original Phillips curve relationship suggested policymakers faced which kind of choice in the short run?
     • A choice between economic growth and price stability
     • A choice between higher exports and higher imports
     • A tradeoff between accepting higher inflation to achieve lower unemployment
     • A tradeoff between deficits and surpluses

     Correct answer: A tradeoff between accepting higher inflation to achieve lower unemployment

     The original Phillips curve suggested a short-run tradeoff in which policymakers could accept higher inflation in order to achieve lower unemployment. Moving up the downward-sloping short-run curve reduces unemployment but at the cost of higher inflation, the central policy dilemma the curve described.

102. An economy invests heavily in education, infrastructure, and research and development over a decade. What is the most likely long-run effect on the long-run aggregate supply and long-run Phillips curve?
     • Long-run aggregate supply shifts left and the natural rate of unemployment rises
     • Both curves remain unchanged because these are demand-side policies
     • Long-run aggregate supply shifts right and the natural rate of unemployment may fall, shifting the long-run Phillips curve left
     • Long-run aggregate supply shifts right but the price level necessarily rises permanently

     Correct answer: Long-run aggregate supply shifts right and the natural rate of unemployment may fall, shifting the long-run Phillips curve left

     Heavy investment in education, infrastructure, and research raises productivity and the capital stock, shifting long-run aggregate supply rightward; by reducing structural unemployment it can also lower the natural rate, shifting the long-run Phillips curve left. Both shifts reflect genuine supply-side improvements in the economy's capacity.

103. Which combination correctly pairs a macroeconomic event with its effect on the short-run Phillips curve?
     • A favorable supply shock shifts the short-run Phillips curve right
     • A negative supply shock shifts the short-run Phillips curve left
     • A decrease in aggregate demand shifts the short-run Phillips curve left
     • An increase in expected inflation shifts the short-run Phillips curve right

     Correct answer: An increase in expected inflation shifts the short-run Phillips curve right

     An increase in expected inflation shifts the short-run Phillips curve rightward, so at any unemployment rate the actual inflation rate is higher. By contrast, a favorable supply shock shifts the curve left, and changes in aggregate demand move the economy along the curve rather than shifting it.

104. A country devotes a larger share of current output to capital goods rather than consumer goods. How does this choice relate to its long-run economic growth?
     • It reduces growth because consumption drives potential output
     • It has no effect on growth because only technology matters
     • It only changes the price level, not real output
     • It tends to increase future growth by expanding the capital stock and potential output

     Correct answer: It tends to increase future growth by expanding the capital stock and potential output

     Devoting more output to capital goods tends to increase future growth because a larger capital stock raises the economy's potential output. By sacrificing some current consumption for investment, the country shifts its long-run aggregate supply and production possibilities curve further outward over time.

105. During a period of stagflation, why is it difficult for policymakers to use aggregate demand policy to fix both problems at once?
     • Because aggregate demand policy has no effect on either inflation or unemployment
     • Because stagflation only affects the long-run aggregate supply curve
     • Because inflation and unemployment always move in opposite directions
     • Because raising aggregate demand worsens inflation while lowering it worsens unemployment

     Correct answer: Because raising aggregate demand worsens inflation while lowering it worsens unemployment

     Stagflation is hard to address with demand policy because raising aggregate demand reduces unemployment but worsens already-high inflation, while reducing aggregate demand lowers inflation but worsens already-high unemployment. Since both problems exist together, demand-side tools cannot solve one without aggravating the other.

106. Which of the following correctly describes the long-run adjustment after the economy temporarily operates beyond full employment along the short-run Phillips curve?
     • The natural rate of unemployment permanently falls
     • Inflation falls and unemployment stays below the natural rate
     • The long-run Phillips curve becomes downward sloping
     • Nominal wages and expected inflation rise, returning unemployment to the natural rate at higher inflation

     Correct answer: Nominal wages and expected inflation rise, returning unemployment to the natural rate at higher inflation

     When the economy temporarily operates beyond full employment, nominal wages and expected inflation eventually rise, returning unemployment to the natural rate but at a higher inflation rate. This self-correcting adjustment is the reason the long-run Phillips curve is vertical at the natural rate.

107. How does a higher national saving rate generally affect the loanable funds market and long-run growth, in contrast to the crowding-out effect of deficits?
     • It shifts the supply of loanable funds left, raising interest rates and reducing investment
     • It shifts the demand for loanable funds right, crowding out private borrowers
     • It has no effect on interest rates or growth
     • It shifts the supply of loanable funds right, lowering interest rates and encouraging investment that supports growth

     Correct answer: It shifts the supply of loanable funds right, lowering interest rates and encouraging investment that supports growth

     A higher saving rate shifts the supply of loanable funds rightward, lowering real interest rates and encouraging private investment, which supports long-run growth. This is the opposite of crowding out, where government borrowing raises rates and reduces investment instead.

108. Which statement about the relationship between the AD-AS model and the Phillips curve is correct?
     • An increase in aggregate demand corresponds to a movement down the short-run Phillips curve
     • A negative supply shock corresponds to a leftward shift of the short-run Phillips curve
     • Long-run aggregate supply has no counterpart in the Phillips curve model
     • An increase in aggregate demand corresponds to a movement up the short-run Phillips curve toward lower unemployment and higher inflation

     Correct answer: An increase in aggregate demand corresponds to a movement up the short-run Phillips curve toward lower unemployment and higher inflation

     An increase in aggregate demand corresponds to a movement up the short-run Phillips curve, lowering unemployment and raising inflation. The two models are linked: changes in aggregate demand trace movements along the short-run Phillips curve, and the vertical long-run aggregate supply curve corresponds to the vertical long-run Phillips curve at the natural rate.

109. Which of the following best captures why economic growth is described as a long-run rather than a short-run phenomenon in AP Macroeconomics?
     • Because it always occurs during recessions
     • Because it depends only on the price level
     • Because it is caused by movements along a fixed short-run aggregate supply curve
     • Because it results from increases in potential output rather than temporary demand changes

     Correct answer: Because it results from increases in potential output rather than temporary demand changes

     Economic growth is a long-run phenomenon because it results from increases in potential output, shown by rightward shifts of long-run aggregate supply, rather than from temporary demand-driven swings in real GDP. Short-run fluctuations move the economy around potential output, but true growth expands that potential.

110. A nation finances ongoing budget deficits primarily by borrowing in domestic financial markets. Which chain of effects best describes the crowding-out mechanism?
     • Higher government borrowing lowers interest rates, increasing investment and growth
     • Higher government borrowing reduces the money supply, causing deflation
     • Higher government borrowing shifts long-run aggregate supply rightward
     • Higher government borrowing raises interest rates, reducing investment and slowing capital accumulation

     Correct answer: Higher government borrowing raises interest rates, reducing investment and slowing capital accumulation

     The crowding-out mechanism runs from higher government borrowing to higher real interest rates, which then reduce private investment and slow capital accumulation. Because investment builds the capital stock that drives long-run growth, sustained crowding out can weaken the economy's future productive capacity.

111. In the balance of payments, which account records a country's exports and imports of goods and services, along with net income from abroad and net transfers?
     • The current account
     • The capital and financial account
     • The official reserve account
     • The fiscal account

     Correct answer: The current account

     The current account is the answer. It tracks the flow of goods and services (the trade balance), net income earned on foreign investments, and net transfer payments between a country and the rest of the world. The capital and financial account, by contrast, records purchases and sales of assets, and there is no separate 'fiscal account' in the balance of payments framework.

112. A country sells $500 billion of goods and services to foreigners while purchasing $620 billion of goods and services from abroad during the same year. What does this situation describe?
     • A trade surplus of $120 billion
     • A balanced trade account
     • A capital account surplus of $1,120 billion
     • A trade deficit of $120 billion

     Correct answer: A trade deficit of $120 billion

     A trade deficit of $120 billion is correct. Because imports of $620 billion exceed exports of $500 billion, the trade balance (exports minus imports) is negative: $500 billion minus $620 billion equals negative $120 billion. A surplus would require exports to exceed imports, and the trade account is clearly not balanced.

113. In the foreign exchange market for the euro, the price on the vertical axis and the quantity on the horizontal axis are best described as which of the following?
     • The price is the interest rate paid on euro deposits, and the quantity is the number of euros saved
     • The price is the inflation rate in the eurozone, and the quantity is real eurozone output
     • The price is the exchange rate of the euro in terms of another currency, and the quantity is the amount of euros traded
     • The price is the eurozone tax rate, and the quantity is government spending

     Correct answer: The price is the exchange rate of the euro in terms of another currency, and the quantity is the amount of euros traded

     The exchange rate of the euro expressed in another currency on the vertical axis, with the quantity of euros traded on the horizontal axis, is correct. The foreign exchange market graph treats one currency as the good being bought and sold; its price is simply how much of another currency it takes to buy it. Interest rates, inflation, and tax rates are not the axes of the foreign exchange diagram.

114. If it takes more U.S. dollars than before to purchase one British pound, with all else equal, what has happened to the two currencies?
     • The dollar has appreciated and the pound has depreciated
     • Both currencies have appreciated
     • Both currencies have depreciated
     • The dollar has depreciated and the pound has appreciated

     Correct answer: The dollar has depreciated and the pound has appreciated

     The dollar has depreciated while the pound has appreciated. When more dollars are required to buy one pound, each dollar buys fewer pounds, meaning the dollar has lost value (depreciated) and the pound has gained value (appreciated). Currency value moves in opposite directions between any two currencies in a single exchange.

115. Holding other factors constant, an increase in the foreign demand for a country's exports will most likely have which effect in the foreign exchange market for that country's currency?
     • It will increase demand for the currency, causing it to appreciate
     • It will increase the supply of the currency, causing it to depreciate
     • It will decrease demand for the currency, causing it to depreciate
     • It will leave the exchange rate unchanged

     Correct answer: It will increase demand for the currency, causing it to appreciate

     Increased demand for the currency, causing it to appreciate, is correct. To buy a country's exports, foreigners must first acquire that country's currency, which raises demand for the currency in the foreign exchange market. A rightward shift in currency demand bids up its exchange rate, producing appreciation rather than depreciation.

116. Net exports, a component of aggregate demand in an open economy, are calculated as which of the following?
     • Exports plus imports
     • Imports minus exports
     • Exports minus imports
     • Total exports divided by total imports

     Correct answer: Exports minus imports

     Exports minus imports is the definition of net exports. This figure captures the net effect of foreign trade on a nation's spending: when exports exceed imports, net exports are positive and add to aggregate demand, while the reverse subtracts from it. Adding the two together or dividing them does not yield the net trade contribution.

117. Suppose a nation's currency appreciates significantly against its trading partners' currencies. Other things equal, what is the most likely effect on that nation's exports and imports?
     • Exports become cheaper for foreigners, so exports rise and imports fall
     • Both exports and imports rise
     • Exports become more expensive for foreigners and imports become cheaper, so exports fall and imports rise
     • Both exports and imports fall

     Correct answer: Exports become more expensive for foreigners and imports become cheaper, so exports fall and imports rise

     Exports falling and imports rising is correct. A stronger currency makes that nation's goods more expensive when priced in foreign currencies, discouraging exports, while making foreign goods cheaper for domestic buyers, encouraging imports. This combination typically pushes net exports downward following currency appreciation.

118. Within the balance of payments, when a foreign investor purchases shares of stock in a domestic company, this transaction is most appropriately recorded in which account?
     • The current account
     • The capital and financial account
     • The merchandise trade account
     • The net income account

     Correct answer: The capital and financial account

     The capital and financial account is the answer because it records international purchases and sales of assets, including stocks, bonds, and direct investment. A foreigner buying domestic stock is acquiring a financial asset, not buying a good or service, so it does not belong in the current account or its trade and income subcomponents.

119. In the foreign exchange market for the Japanese yen, a rise in U.S. interest rates relative to Japanese interest rates would most likely cause which change, holding other factors constant?
     • An increase in the demand for yen and appreciation of the yen
     • A decrease in the supply of yen and appreciation of the yen
     • No change in the foreign exchange market for yen
     • An increase in the supply of yen and depreciation of the yen

     Correct answer: An increase in the supply of yen and depreciation of the yen

     An increase in the supply of yen and depreciation of the yen is correct. Higher U.S. interest rates make U.S. financial assets more attractive, prompting Japanese investors to convert yen into dollars to invest abroad. This raises the supply of yen offered in the foreign exchange market, pushing the yen's exchange rate down.

120. A country consistently records that the value of the goods and services it imports exceeds the value of the goods and services it exports. This persistent condition is best described as which of the following?
     • A current account surplus
     • A balanced current account
     • An appreciation of its currency
     • A trade deficit

     Correct answer: A trade deficit

     A trade deficit is correct because it occurs whenever imports of goods and services exceed exports, making the trade balance negative. A surplus would require the opposite relationship, and a balanced account would require exports and imports to be equal; currency appreciation describes a change in exchange-rate value, not a trade flow.

121. In the foreign exchange market, the quantity of a currency demanded generally rises as the price of that currency falls. Which statement best explains this downward-sloping demand for a currency?
     • As the currency depreciates, the country's goods become cheaper to foreigners, increasing the amount of currency they need to buy those goods
     • As the currency appreciates, foreigners need more of it to buy the same goods
     • A lower exchange rate raises the domestic inflation rate directly
     • A lower exchange rate has no effect on the quantity of currency demanded

     Correct answer: As the currency depreciates, the country's goods become cheaper to foreigners, increasing the amount of currency they need to buy those goods

     The first explanation is correct: as a currency depreciates, the country's exports become cheaper for foreign buyers, so they demand more of that currency to purchase the now-cheaper goods. This inverse relationship between a currency's price and the quantity demanded gives the foreign exchange demand curve its downward slope.

122. Other things equal, a depreciation of a nation's currency is most likely to have which effect on that nation's net exports?
     • Net exports increase because exports become cheaper abroad and imports become more expensive at home
     • Net exports decrease because exports become more expensive abroad
     • Net exports remain unchanged because trade does not respond to exchange rates
     • Net exports decrease because imports become cheaper at home

     Correct answer: Net exports increase because exports become cheaper abroad and imports become more expensive at home

     Net exports increasing is correct. A weaker currency lowers the foreign-currency price of the nation's exports, boosting export sales, while raising the domestic price of imports, which discourages imports. With exports rising and imports falling, net exports (exports minus imports) tend to increase.

123. Which pairing correctly matches a balance-of-payments transaction with the account in which it is recorded?
     • A domestic firm exporting machinery abroad is recorded in the capital and financial account
     • A foreign tourist paying for hotel services in the country is recorded in the capital and financial account
     • A domestic resident buying a bond issued by a foreign government is recorded in the capital and financial account
     • Net investment income earned from assets held abroad is recorded in the capital and financial account

     Correct answer: A domestic resident buying a bond issued by a foreign government is recorded in the capital and financial account

     A domestic resident buying a foreign government bond being recorded in the capital and financial account is correct, because that account captures cross-border purchases of financial assets. Exporting machinery, foreign tourist spending on services, and net investment income are all current account entries, since they involve goods, services, or income flows rather than asset ownership.

124. A central bank unexpectedly raises its policy interest rate, attracting financial capital from abroad. In the foreign exchange market and in the trade sector, what is the most likely sequence of effects on the nation's currency and net exports?
     • The currency depreciates and net exports rise
     • The currency appreciates and net exports fall
     • The currency appreciates and net exports rise
     • The currency depreciates and net exports fall

     Correct answer: The currency appreciates and net exports fall

     The currency appreciating and net exports falling is correct. A higher interest rate draws foreign financial capital, increasing demand for the nation's currency and causing it to appreciate. A stronger currency makes exports pricier abroad and imports cheaper at home, which reduces net exports. The other sequences contradict this chain of cause and effect.

125. When a U.S. resident buys a new smartphone that was manufactured entirely in another country, how is this transaction recorded in U.S. GDP under the expenditure approach?
     • It adds the price to consumption and subtracts the same amount as imports, leaving GDP unchanged
     • It adds the full price of the phone to consumption with no offsetting entry
     • It is added to net exports because the phone crossed a border
     • It is excluded entirely because consumers are not counted in GDP

     Correct answer: It adds the price to consumption and subtracts the same amount as imports, leaving GDP unchanged

     The correct choice is that the purchase adds to consumption and subtracts the same amount as imports, leaving U.S. GDP unchanged. The expenditure formula is C + I + G + (X - M); spending on the imported phone raises C but is offset by a rise in M, so domestically produced output is unaffected, which is exactly what GDP is meant to measure.

126. A government statistical agency reports that this year's nominal GDP is larger than last year's, but real GDP is smaller. What can be concluded about the economy between the two years?
     • The economy produced less physical output while the price level rose enough to raise nominal GDP
     • The economy produced more physical output and prices fell
     • Both output and prices fell
     • Nothing can be concluded without the unemployment rate

     Correct answer: The economy produced less physical output while the price level rose enough to raise nominal GDP

     The correct conclusion is that physical output fell while the price level rose enough to push nominal GDP up. Real GDP holds prices constant and isolates quantity, so a decline in real GDP means less output; nominal GDP rising despite that decline must be driven by higher prices, since nominal GDP reflects both quantity and current prices.

127. Which of the following would be counted as investment (I) rather than consumption (C) in the GDP expenditure approach?
     • A family buying groceries for the week
     • A bakery purchasing a new commercial oven to expand production
     • A household paying its monthly electricity bill
     • A student buying a used laptop from a classmate

     Correct answer: A bakery purchasing a new commercial oven to expand production

     The correct answer is the bakery purchasing a new commercial oven, which counts as investment. In national income accounting, investment includes business purchases of new capital goods such as machinery and equipment used to produce output, whereas household purchases of goods and services are consumption and a used-good resale is excluded entirely.

128. An unpaid parent who stays home full time to care for their own children performs valuable work, yet this activity is not included in GDP. What is the primary reason?
     • Childcare is considered an intermediate service
     • It would be double counting other household spending
     • Care work is classified as a transfer payment
     • The work does not pass through a market and has no recorded price

     Correct answer: The work does not pass through a market and has no recorded price

     The correct reason is that the work does not pass through a market and has no recorded price. GDP measures the market value of final goods and services, so non-market household production, even when economically valuable, is omitted because there is no transaction price to record, which is a recognized limitation of GDP.

129. A retired person receives a monthly Social Security check from the government. How is this payment treated in calculating GDP?
     • It is added to government purchases (G)
     • It is added to consumption when received
     • It is excluded because it is a transfer payment, not a purchase of current output
     • It is subtracted as a negative export

     Correct answer: It is excluded because it is a transfer payment, not a purchase of current output

     The correct treatment is exclusion, because a Social Security check is a transfer payment, not a payment for currently produced goods or services. Government purchases (G) include only spending on output the government buys; transfer payments merely redistribute income and would double count when the recipient later spends the money on goods already eligible for GDP.

130. Real GDP per capita is sometimes criticized as an imperfect measure of well-being. Which limitation does this measure specifically fail to capture?
     • Changes in the overall price level over time
     • The size of the labor force
     • How total income is distributed across the population
     • The difference between nominal and real values

     Correct answer: How total income is distributed across the population

     The correct limitation is that real GDP per capita ignores how income is distributed across the population. Because it is an average of output per person, a country could show a high figure while most income is concentrated among a few people; the average says nothing about inequality, even though it does adjust for prices and population size.

131. In a four-sector circular flow model that includes households, firms, government, and the foreign sector, which flow represents the foreign sector's connection to the domestic economy?
     • Taxes paid by households to the government
     • Net exports, reflecting spending on domestic goods by foreigners minus domestic spending on foreign goods
     • Wages flowing from firms to households
     • Saving deposited by households into financial markets

     Correct answer: Net exports, reflecting spending on domestic goods by foreigners minus domestic spending on foreign goods

     The correct flow is net exports, which captures foreign purchases of domestic output minus domestic purchases of foreign output. In the four-sector model the foreign sector enters through trade, so net exports (X - M) is the link, while taxes, wages, and saving describe the household, firm, and financial-market relationships instead.

132. A worker quits a stable job to spend two months relocating and searching for a position in a different city. During this search she is classified as which type of unemployed?
     • Cyclically unemployed
     • Structurally unemployed
     • Frictionally unemployed
     • Not in the labor force

     Correct answer: Frictionally unemployed

     The correct classification is frictionally unemployed, because she is temporarily between jobs while searching for a suitable match. Frictional unemployment arises from the normal time it takes to find work and from voluntary transitions; it is not caused by a downturn (cyclical) or by a mismatch of skills to available jobs (structural).

133. An economy is operating at full employment. Which statement about the types of unemployment present is correct?
     • There is zero unemployment of any kind
     • Only cyclical unemployment remains
     • Frictional unemployment is zero while structural unemployment remains
     • Cyclical unemployment is zero, but frictional and structural unemployment still exist

     Correct answer: Cyclical unemployment is zero, but frictional and structural unemployment still exist

     The correct statement is that cyclical unemployment is zero while frictional and structural unemployment still exist. Full employment means the economy is at the natural rate of unemployment, which by definition includes ongoing frictional and structural unemployment; only the cyclical component tied to the business cycle has been eliminated.

134. A textile factory permanently closes because consumers have shifted to imported clothing, and its former workers lack the skills demanded by growing technology firms. These displaced workers are best described as experiencing which type of unemployment?
     • Frictional unemployment
     • Structural unemployment
     • Cyclical unemployment
     • Seasonal unemployment

     Correct answer: Structural unemployment

     The correct type is structural unemployment, which occurs when there is a fundamental mismatch between workers' skills or locations and the jobs available. The permanent shift in demand and the skills gap distinguish it from frictional unemployment (normal job search) and cyclical unemployment (caused by an economy-wide downturn).

135. A country has a working-age population of 250 million. Of these, 160 million are employed, 10 million are unemployed and actively seeking work, and the rest are not in the labor force. What is the labor force participation rate?
     • 64 percent
     • 94 percent
     • 60 percent
     • 68 percent

     Correct answer: 68 percent

     The correct answer is 68 percent. The labor force equals employed plus unemployed, or 160 + 10 = 170 million; the participation rate is the labor force divided by the working-age population, 170 / 250 = 0.68, which is 68 percent.

136. A discouraged worker who has stopped looking for a job after a long unsuccessful search affects the measured unemployment rate in which way?
     • It raises the measured unemployment rate
     • It lowers the measured unemployment rate because the person leaves the labor force
     • It has no effect on any labor statistic
     • It raises the labor force participation rate

     Correct answer: It lowers the measured unemployment rate because the person leaves the labor force

     The correct effect is that the measured unemployment rate falls, because a discouraged worker who stops searching is no longer counted as unemployed or in the labor force. This causes official statistics to understate true labor-market weakness, since the person still wants work but is excluded from both the numerator and denominator of the unemployment rate.

137. The consumer price index (CPI) and the GDP deflator can give different inflation readings in the same year. Which difference best explains why?
     • The CPI is always larger because it includes more goods
     • The CPI tracks a fixed basket of goods bought by typical consumers, while the GDP deflator covers all domestically produced goods and services
     • The GDP deflator excludes services entirely
     • The CPI includes imported goods but excludes domestic goods

     Correct answer: The CPI tracks a fixed basket of goods bought by typical consumers, while the GDP deflator covers all domestically produced goods and services

     The correct explanation is that the CPI tracks a fixed market basket of goods purchased by a typical urban consumer, including imports, whereas the GDP deflator measures prices of all goods and services produced domestically. Because they cover different sets of goods, the two indices can report different inflation rates in the same period.

138. A market basket cost $250 in the base year and $275 in the current year. What is the current-year consumer price index, and what does it indicate?
     • 100, indicating no price change
     • 90, indicating prices fell 10 percent
     • 110, indicating prices rose 10 percent since the base year
     • 125, indicating prices rose 25 percent

     Correct answer: 110, indicating prices rose 10 percent since the base year

     The correct answer is a CPI of 110, indicating prices rose 10 percent since the base year. The CPI equals the current basket cost divided by the base-year basket cost times 100, or (275 / 250) x 100 = 110; a value of 110 means the basket costs 10 percent more than in the base year.

139. A nation's CPI rises from 200 to 210 over one year. What is the inflation rate for that year?
     • 10 percent
     • 2.1 percent
     • 5 percent
     • 4.76 percent

     Correct answer: 5 percent

     The correct answer is 5 percent. The inflation rate is the change in the index divided by the starting index times 100; here (210 - 200) / 200 x 100 = 5 percent, so the price level rose by 5 percent over the year.

140. Substitution bias is a recognized reason the CPI may misstate the true cost of living. What does substitution bias cause the CPI to do?
     • Understate inflation because new products are added too quickly
     • Overstate inflation because the fixed basket ignores consumers switching to cheaper alternatives
     • Understate inflation because quality improvements are overlooked
     • Perfectly measure the cost of living over time

     Correct answer: Overstate inflation because the fixed basket ignores consumers switching to cheaper alternatives

     The correct answer is that substitution bias causes the CPI to overstate inflation. Because the CPI uses a fixed basket, it does not account for consumers switching away from goods whose prices rise toward cheaper substitutes; ignoring this behavior makes the measured increase in living costs larger than the true increase consumers actually experience.

141. A retiree relies on a fixed monthly pension whose dollar amount never changes. During a period of unexpectedly high inflation, how is this retiree affected?
     • Her purchasing power rises because nominal income is fixed
     • She is unaffected since inflation only hurts borrowers
     • Her purchasing power falls because the same dollars buy fewer goods
     • Her real income rises along with the price level

     Correct answer: Her purchasing power falls because the same dollars buy fewer goods

     The correct answer is that her purchasing power falls because the same fixed dollars buy fewer goods as prices rise. People on fixed nominal incomes, such as pensioners with non-indexed payments, are among those hurt most by unexpected inflation because their nominal income does not adjust upward while the cost of living increases.

142. Lenders who issued fixed-rate loans and savers holding cash are commonly identified as which group during a period of unexpectedly high inflation?
     • Winners, because their money gains value
     • Unaffected, because interest rates adjust instantly
     • Winners, because real interest rates rise
     • Losers, because they are repaid in dollars that are worth less than expected

     Correct answer: Losers, because they are repaid in dollars that are worth less than expected

     The correct answer is that they are losers, because unexpected inflation means lenders are repaid in dollars worth less than anticipated and savers holding cash see its real value erode. When actual inflation exceeds what was expected, value shifts from creditors and cash holders to debtors who repay with cheaper dollars.

143. If the nominal interest rate on a savings account is 6 percent and the inflation rate over the year is 4 percent, what is the approximate real interest rate?
     • 2 percent
     • 10 percent
     • 6 percent
     • 1.5 percent

     Correct answer: 2 percent

     The correct answer is 2 percent. By the Fisher relationship, the real interest rate approximately equals the nominal interest rate minus the inflation rate; here 6 percent minus 4 percent equals a real return of 2 percent, which reflects the true increase in purchasing power earned.

144. An economy moves from the peak of the business cycle into a period of declining real GDP and rising unemployment. This phase is called a what?
     • Recession (contraction)
     • Expansion
     • Trough
     • Recovery

     Correct answer: Recession (contraction)

     The correct answer is a recession, also called a contraction. After a peak, the business cycle enters a phase of falling real GDP and rising unemployment until it reaches a trough; expansion and recovery describe the rising phase, and the trough is the lowest point, not the downward movement itself.

145. At the trough of the business cycle, which combination of conditions is most likely present?
     • Real GDP at its highest and unemployment at its lowest
     • Real GDP rising rapidly with falling unemployment
     • Stable prices with full employment
     • Real GDP at its lowest and unemployment at its highest before the economy begins to recover

     Correct answer: Real GDP at its lowest and unemployment at its highest before the economy begins to recover

     The correct answer is real GDP at its lowest and unemployment at its highest before recovery begins. The trough is the bottom of the business cycle, marking the turning point where contraction ends and expansion starts, so output is at its low and joblessness is near its peak at this stage.

146. The total value of an economy's output measured at the prices that prevailed in the year the output was produced is known as what?
     • Nominal GDP
     • Real GDP
     • GDP per capita
     • Net domestic product

     Correct answer: Nominal GDP

     The correct answer is nominal GDP, which values current output at current-year prices. Because it uses the prices prevailing in the production year, nominal GDP can change due to changes in either output or prices; real GDP, by contrast, holds prices constant at a base year to isolate changes in output.

147. In a year, an economy's nominal GDP is $1,050 billion and its real GDP is $1,000 billion. What is the GDP deflator, and what does it imply about prices relative to the base year?
     • 105, prices have risen 5 percent since the base year
     • 95, prices have fallen since the base year
     • 150, prices have risen 50 percent
     • 100, prices are unchanged

     Correct answer: 105, prices have risen 5 percent since the base year

     The correct answer is a GDP deflator of 105, implying prices have risen 5 percent since the base year. The deflator equals nominal GDP divided by real GDP times 100, or (1,050 / 1,000) x 100 = 105; a value above 100 indicates the overall price level has increased relative to the base year.

148. Why do economists use real GDP rather than nominal GDP when comparing the size of an economy's output across different years?
     • Real GDP includes more categories of spending than nominal GDP
     • Nominal GDP cannot be calculated for past years
     • Real GDP counts intermediate goods that nominal GDP omits
     • Real GDP removes the effect of price changes so that differences reflect actual changes in output

     Correct answer: Real GDP removes the effect of price changes so that differences reflect actual changes in output

     The correct reason is that real GDP removes the effect of price changes so differences across years reflect actual changes in output. Nominal GDP can rise simply because prices increased even if no additional goods were produced; by holding prices at a constant base year, real GDP isolates genuine growth in production for valid comparisons.

149. An economic indicator that tends to change direction only after the overall economy has already turned, such as the average duration of unemployment, is best classified as which type of indicator?
     • Lagging indicator
     • Leading indicator
     • Coincident indicator
     • Composite price index

     Correct answer: Lagging indicator

     The correct classification is a lagging indicator, which changes direction after the broader economy has already shifted. The average duration of unemployment typically keeps rising for a time even after a recovery begins, confirming past turning points rather than predicting them as a leading indicator would.
