1. 1. Which of the following is a macroeconomic question rather than a microeconomic question?

   • A. Why did the price of avocados rise this summer?
   • B. How does a minimum wage affect employment at fast-food restaurants?
   • C. Why did the overall unemployment rate increase last quarter?
   • D. Should a firm hire one more worker given current wages?
   Show answer

   Correct answer: C. Why did the overall unemployment rate increase last quarter?

   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. 2. 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
   Show answer

   Correct answer: B. Falling real GDP and rising unemployment

   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.

3. 3. 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
   Show answer

   Correct answer: C. Contraction

   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.

4. 4. 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
   Show answer

   Correct answer: B. Real GDP falls because all three are leakages that drain spending from the flow

   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.

5. 5. In the expenditure approach to GDP, which of the following is classified as investment (I) rather than consumption (C)?

   • A. A household purchasing a new refrigerator
   • B. A household purchasing a newly constructed home
   • C. A household purchasing shares of stock in a technology company
   • D. A household purchasing groceries for the week
   Show answer

   Correct answer: B. A household purchasing a newly constructed home

   In GDP accounting (a framework formalized by Simon Kuznets in the 1930s and 1940s) residential construction counts as investment (I), not consumption. A new home is a long-lived asset providing services over decades, which is why economists treat it like business capital. Option A is a consumer durable good (consumption). Option C is a financial transaction not counted in GDP at all, because no new good or service is produced. Option D is non-durable consumption.

6. 6. Which of the following scenarios describes a situation where macroeconomic analysis is essential but microeconomic analysis alone would be insufficient?

   • A. A firm deciding whether to hire an additional worker based on the worker's marginal revenue product
   • B. A consumer choosing between two brands of cereal based on price and quality
   • C. The Federal Reserve raising interest rates to combat economy-wide inflation, which simultaneously affects housing markets, business investment, and the exchange rate
   • D. A city government evaluating whether to build a new park based on local cost-benefit analysis
   Show answer

   Correct answer: C. The Federal Reserve raising interest rates to combat economy-wide inflation, which simultaneously affects housing markets, business investment, and the exchange rate

   The Federal Reserve's interest rate decisions operate through economy-wide channels, affecting the aggregate price level, total investment, exchange rates, and employment across all sectors simultaneously. The Fed has set monetary policy for the entire U.S. economy since its founding in 1913, and analyzing those decisions requires macroeconomic tools. Option A is a firm-level labor demand decision. Option B is a consumer choice problem. Option D is a localized public finance question addressable with micro-level cost-benefit analysis.

7. 7. Country X can produce 100 units of wheat or 50 units of cloth with a given set of resources. Country Y can produce 60 units of wheat or 40 units of cloth. Which country has the comparative advantage in cloth?

   • A. Country X, because it can produce more cloth
   • B. Country Y, because cloth has a lower opportunity cost there
   • C. Country X, because it has absolute advantage in both goods
   • D. Neither; the countries should not trade
   Show answer

   Correct answer: B. Country Y, because cloth has a lower opportunity cost there

   Opportunity cost of one cloth: Country X gives up 100/50 = 2 wheat. Country Y gives up 60/40 = 1.5 wheat. Country Y has the LOWER opportunity cost for cloth, so it holds the comparative advantage there. Country X has comparative advantage in wheat. Absolute advantage is irrelevant to the direction of beneficial trade.

8. 8. The three fundamental questions every economic system must answer are:

   • A. How much to consume, save, and invest
   • B. What to produce, how to produce it, and for whom to produce it
   • C. When to raise taxes, cut spending, and intervene
   • D. How to grow, redistribute, and regulate
   Show answer

   Correct answer: B. What to produce, how to produce it, and for whom to produce it

   'What, how, and for whom' is the classic triad. Every society — market, command, or mixed — must decide which goods get produced, the mix of inputs used, and how the output gets distributed. Different systems answer these differently (market prices vs. central planning), but the questions themselves are universal.
