NAEP Economics Grade 3 — Questions and Answers
Question 1: If the unemployment rate falls below the natural rate of unemployment, economists typically expect:
- Deflation and falling wages
- Inflation due to upward wage pressure (Correct answer)
- A decrease in consumer spending
- A reduction in government tax revenue
Correct answer: Inflation due to upward wage pressure
When unemployment falls below the natural rate, labor markets tighten, giving workers bargaining power to demand higher wages, which can fuel inflation.
Question 2: A musician spends $500 recording an album and sells 100 copies at $8 each. What is the musician's profit?
- $800
- $300 (Correct answer)
- $500
- $1,300
Correct answer: $300
Profit = total revenue minus total cost: (100 × $8) − $500 = $800 − $500 = $300.
Question 3: The Federal Reserve raises interest rates. Which of the following is the most likely direct effect?
- Businesses borrow more to expand
- Consumer spending on credit increases
- Borrowing becomes more expensive, slowing spending (Correct answer)
- The government collects more tax revenue
Correct answer: Borrowing becomes more expensive, slowing spending
Higher interest rates increase the cost of borrowing, which discourages consumer and business spending and slows economic activity.
Question 4: Which factor of production refers to the natural resources used in producing goods?
- Capital
- Labor
- Land (Correct answer)
- Entrepreneurship
Correct answer: Land
Land as a factor of production includes all natural resources — minerals, water, forests, and agricultural soil.
Question 5: A store sells its last unit of a product for $15 more than it cost to produce. This $15 represents the store's:
- Variable cost
- Fixed cost
- Marginal profit (Correct answer)
- Sunk cost
Correct answer: Marginal profit
Marginal profit is the additional profit earned from selling one more unit, calculated as marginal revenue minus marginal cost.
Question 6: Which scenario best illustrates specialization leading to greater efficiency?
- A worker performs every step of car production alone
- Assembly-line workers each master one specific task (Correct answer)
- A farmer grows every type of crop on the same land
- A country produces all goods it needs domestically
Correct answer: Assembly-line workers each master one specific task
Specialization, as seen in assembly-line production, increases efficiency because workers become highly skilled at their specific task.
Question 7: A city builds a new park that benefits all residents whether or not they contributed taxes. The park is best described as a:
- Private good
- Club good
- Public good (Correct answer)
- Merit good only
Correct answer: Public good
A public good is non-excludable (no one can be prevented from using it) and non-rival (one person's use doesn't reduce availability to others).
