If the government sets a price ceiling below the equilibrium price, the most likely result is:
A. A surplus
B. A shortage✓ 答案
C. No change in the market
D. An increase in equilibrium price
解說
A price ceiling below equilibrium makes the legal price lower than the market-clearing price, so quantity demanded exceeds quantity supplied, creating a shortage. A surplus occurs with a price floor, not a ceiling.
