A. A minimum price
B. A subsidy
C. A specific tax
D. A percentage tax


参考答案:  B


本题详细解析:

B

The imposition of the maximum price P${}_{Max}$ causes excess demand of Q${}_2-Q_1$. This excess demand is eliminated when the subsidy shifts the supply curve down.

Choice A is incorrect, as a minimum price could not be imposed if a maximum price is in effect. Further, effective minimum prices cause excess supply.

Choices C and D are incorrect as these indirect taxes would shift the supply curve to the left.
