A price ceiling is imposed below the equilibrium price. Which of the following is NOT a likely consequence?
A. A shortage of the good
B. Non-price rationing such as queuing
C. A black market may emerge
D. A surplus of the good✓ 答案
解說
A price ceiling below equilibrium creates a shortage (quantity demanded > quantity supplied). To allocate scarce goods, non-price rationing and black markets often arise. A surplus is associated with a price floor, not a ceiling.
