AP Macro MACRO: Concepts and Models 2 — Questions and Answers
Question 1: In the circular flow model, which of the following represents a leakage from the spending stream?
- Consumer spending
- Business investment
- Household saving (Correct answer)
- Government transfer payments
Correct answer: Household saving
Saving is a leakage because it withdraws income from the circular flow rather than returning it as spending.
Question 2: Which model best illustrates the trade-off a society faces when deciding how much of each of two goods to produce?
- Circular flow model
- Production possibilities frontier (Correct answer)
- Aggregate demand-aggregate supply model
- Money market model
Correct answer: Production possibilities frontier
The production possibilities frontier (PPF) shows all combinations of two goods an economy can produce given its resources, illustrating opportunity cost trade-offs.
Question 3: A point inside the production possibilities frontier indicates that an economy is:
- Operating at full employment
- Using resources efficiently
- Operating with some unemployed or underutilized resources (Correct answer)
- Beyond its productive capacity
Correct answer: Operating with some unemployed or underutilized resources
A point inside the PPF means the economy is not using all available resources efficiently, indicating unemployment or underutilization.
Question 4: In macroeconomic models, the term 'ceteris paribus' means:
- All variables change simultaneously
- Only the price level changes
- All other variables are held constant (Correct answer)
- The economy is in long-run equilibrium
Correct answer: All other variables are held constant
Ceteris paribus is a Latin phrase meaning 'all other things being equal,' used to isolate the effect of one variable.
Question 5: Which of the following is the BEST example of a macroeconomic variable?
- The price of a Toyota Camry
- Apple's quarterly revenue
- The national unemployment rate (Correct answer)
- The wage paid to a specific nurse
Correct answer: The national unemployment rate
The national unemployment rate is an aggregate measure of the entire economy, making it a macroeconomic variable.
Question 6: The concept of opportunity cost in macroeconomics suggests that:
- All resources are free if the government provides them
- The real cost of a choice is the next best alternative forgone (Correct answer)
- Opportunity costs only apply to consumer decisions
- Governments face no opportunity costs when spending
Correct answer: The real cost of a choice is the next best alternative forgone
Opportunity cost is the value of the best alternative sacrificed when making any economic decision.
Question 7: If an economy is producing at a point on its PPF, any increase in production of one good necessarily requires:
- An increase in total resources
- A decrease in production of the other good (Correct answer)
- An improvement in technology
- An increase in foreign trade
Correct answer: A decrease in production of the other good
On the PPF, resources are fully employed, so producing more of one good requires reallocating resources and producing less of the other.
