A binding quota sets the maximum quantity below the equilibrium quantity. Compared with the free market, the price tends to be:
A. Lower, because fewer goods always mean a lower price.
B. Unchanged, because a quota is not a price control.
C. Higher, because the restricted quantity meets demand further up the demand curve.✓ 答案
D. Zero, because trade above the quota is illegal.
解說
The quota caps quantity. Buyers’ willingness to pay at that smaller quantity is read off the demand curve, and it is higher than the old equilibrium price. A quota is not itself a price tag, but it changes the price that clears the allowed quantity.
