- (A) Why did the price of avocados rise this summer?

- (B) Household saving
- (C) Business investment in new equipment
- (D) Export revenue from foreign buyers
3. During a recession, which combination of indicators would you most likely observe?
- (A) Rising real GDP and falling unemployment
- (B) Falling real GDP and rising unemployment
- (C) Rising real GDP and rising unemployment
- (D) Falling real GDP and falling inflation only
4. A country where the government sets production quotas for all industries and determines prices centrally is best described as:
- (A) A market economy
- (B) A mixed economy
- (C) A command economy
- (D) A traditional economy
5. If the three macroeconomic goals are growth, low unemployment, and stable prices, which scenario illustrates a conflict between these goals?
- (A) A policy that raises GDP growth and lowers unemployment simultaneously
- (B) A central bank raising interest rates to fight inflation, which slows growth and raises unemployment
- (C) An economy at full employment with stable 2% inflation
- (D) A technological breakthrough that increases output without raising prices
6. An economy's real GDP peaked in March and has been declining for seven months. Unemployment has risen from 3.8% to 6.5%. This economy is most likely in which phase of the business cycle?
- (A) Expansion
- (B) Peak
- (C) Contraction
- (D) Trough
7. In the circular flow model, when households pay income taxes to the government, this represents:
- (A) An injection into the circular flow
- (B) A leakage from the circular flow
- (C) A transfer payment
- (D) An increase in aggregate demand
8. Country A has GDP of $500 billion and GNP of $540 billion. Which of the following best explains the $40 billion difference?
- (A) Country A imports $40 billion more than it exports
- (B) Country A's citizens earn $40 billion more from production abroad than foreigners earn from production inside Country A
- (C) Country A's government spends $40 billion on transfer payments
- (D) Country A's underground economy accounts for $40 billion in unreported output
9. In the circular flow model, a country simultaneously increases its savings rate, raises taxes, and expands imports. Assuming no offsetting changes in injections, what is the most likely effect on the economy?
- (A) Real GDP rises because savings fund future investment
- (B) Real GDP falls because all three are leakages that drain spending from the flow
- (C) Real GDP is unaffected because leakages always equal injections
- (D) The price level rises due to reduced supply of goods
10. An economy is at the trough of the business cycle. Which of the following combinations is most consistent with this phase?
- (A) High consumer confidence, accelerating GDP growth, and falling unemployment
- (B) Peak corporate profits, maximum capacity utilization, and emerging inflationary pressure
- (C) GDP has stopped declining, unemployment is at its highest, and idle capacity is at its maximum
- (D) GDP is declining rapidly, businesses are cutting inventories, and layoffs are accelerating
Basic Macroeconomic Concepts: answer key
1. (C) Macroeconomics studies economy-wide phenomena like the overall unemployment rate, national output, and the general price level. The other three options focus on individual markets or firm-level decisions, which belong to microeconomics. Avocado pricing is a single-market question. Fast-food employment under minimum wage is a labor-market-specific question. The hiring decision is a firm-level marginal analysis.
2. (B) Saving removes money from the consumption stream, reducing the circular flow. The three leakages are saving, taxes, and imports. Options A, C, and D are all injections: government purchases inject public spending, business investment injects capital spending, and exports inject foreign spending back into the domestic flow.
3. (B) Recessions are defined by declining real GDP. As firms cut production, they lay off workers, pushing unemployment higher. The 2008-2009 recession saw U.S. GDP contract roughly 4.3% while unemployment doubled from about 5% to 10%. Option A describes expansion. Option C is contradictory under normal circumstances. Option D ignores the labor market entirely.
4. (C) Central government control over production quotas and prices defines a command economy, which is the model the Soviet Union operated from the late 1920s until its dissolution in 1991. Option A relies on private decision-making and price signals. Option B blends both. Option D refers to economies organized around custom and tradition, not centralized government planning.
5. (B) When a central bank raises interest rates to tame inflation, as Volcker did in 1981, it deliberately slows growth and accepts higher unemployment. That is a direct conflict between the stable-prices goal and the other two. Option A shows goals aligning. Option C describes an ideal equilibrium. Option D is a supply-side improvement that advances all three goals simultaneously.
6. (C) Seven months of declining GDP and sharply rising unemployment are the hallmarks of a contraction. The peak already occurred in March. The economy has moved past it into recession. Option D (trough) would only apply once the decline bottoms out and stabilization begins, which has not happened yet.
7. (B) Taxes pull money out of the household spending stream, because dollars that would otherwise have been spent on goods and services flow to the government instead. That makes taxes a leakage. Option A is backwards; injections add to the flow (investment, government spending, exports). Option C is incorrect because transfer payments flow from government to households, not the reverse.
8. (B) GNP measures output by a country's citizens regardless of location; GDP measures output within borders regardless of citizenship. When GNP exceeds GDP by $40 billion, citizens earn that much more abroad than foreigners earn domestically. Option A confuses the trade balance with factor income flows. Option C is wrong because transfer payments are not counted in GDP or GNP, since no new production occurs. Option D fails because the underground economy is excluded from both measures equally.
9. (B) Saving, taxes, and imports are the three leakages. When all three increase simultaneously with no offsetting rise in injections, more money drains out of the spending stream than flows back in. Real GDP falls. Option A incorrectly assumes savings automatically become investment. Keynes identified this fallacy of composition in 1936 as the paradox of thrift. Option C states a long-run equilibrium condition, but with no offsetting injections, the economy contracts before reaching equilibrium. Option D describes a supply-side effect unrelated to demand-side leakages.
10. (C) The trough is the lowest point. Output has bottomed out, unemployment peaks, and factories sit idle, but the rate of decline has stopped. The U.S. economy reached its trough in June 2009 before the longest expansion in recorded history began. Option A describes mid-expansion. Option B describes conditions near the peak. Option D describes active contraction, which precedes the trough.
