If a normal good becomes more expensive while consumer income remains unchanged, the consumer's real purchasing power generally:
Correct answer: B. Decreases because the consumer can buy fewer goods
- A. Increases because the good earns more revenue
- B. Decreases because the consumer can buy fewer goods
- C. Remains fixed because nominal income is unchanged
- D. Increases because the substitution effect disappears
Explanation
A higher price reduces the quantity of goods that a fixed income can purchase, so real purchasing power falls. Unchanged nominal income does not mean unchanged real income.
