NAEP Economics Grade 4 — Questions and Answers
Question 1: When the price of smartphones falls significantly, many consumers choose to buy them instead of older flip phones. This reflects:
- The income effect only
- The substitution effect (Correct answer)
- A supply-side shock
- Diminishing marginal utility
Correct answer: The substitution effect
The substitution effect occurs when consumers switch to a relatively cheaper good as its price falls compared to alternatives.
Question 2: Which best explains why the U.S. dollar is considered a 'fiat currency'?
- It is backed by gold reserves held at Fort Knox
- Its value comes from government decree, not a physical commodity (Correct answer)
- It can be exchanged for silver at any bank
- Its value is determined solely by the stock market
Correct answer: Its value comes from government decree, not a physical commodity
Fiat currency derives its value from government declaration and public trust rather than being backed by a physical commodity like gold.
Question 3: A nation experiences rapid technological improvement in agriculture. On a production possibilities frontier graph showing food and electronics, this would:
- Shift the entire frontier inward
- Shift only the food axis outward, rotating the frontier (Correct answer)
- Shift only the electronics axis outward
- Not affect the frontier at all
Correct answer: Shift only the food axis outward, rotating the frontier
A technological improvement in only one sector rotates the PPF outward along that sector's axis, increasing maximum output of that good.
Question 4: Which of the following is an example of structural unemployment?
- A ski instructor unemployed during the summer
- A factory worker whose job was eliminated by automation (Correct answer)
- A recent graduate searching for a first job
- A worker temporarily laid off during an economic recession
Correct answer: A factory worker whose job was eliminated by automation
Structural unemployment occurs when workers' skills no longer match available jobs, often due to technological change or industry shifts.
Question 5: A business has total revenue of $50,000 and total costs of $45,000. It is operating in a competitive market. What should it do in the short run?
- Shut down immediately to minimize losses
- Continue operating since it is earning a profit (Correct answer)
- Reduce prices to gain market share
- Seek a government subsidy to survive
Correct answer: Continue operating since it is earning a profit
With revenue exceeding total costs, the business is profitable and should continue operating in the short run.

- The total output of the economy
- Changes in the average prices paid by consumers over time (Correct answer)
- The unemployment rate across industries
- Government budget deficits
Correct answer: Changes in the average prices paid by consumers over time
The CPI tracks price changes for a basket of goods and services commonly purchased by households, serving as the main inflation indicator.

- Absolute advantage
- Comparative advantage (Correct answer)
- Protectionism
- Economic nationalism
Correct answer: Comparative advantage
Comparative advantage states that countries benefit by specializing in goods with lower opportunity costs and trading for others.
