2014年AP微观经济学真题部分内容：
1. Steverail, the only provider of train service operating between two cities, is currently incurring economic losses.
(a) Using a correctly labeled graph, show each of the following.
(i) Steverail’s loss-minimizing price and quantity, labeled Pm and Qm, respectively
(ii) The area of economic losses, shaded completely
(iii) The allocatively efficient quantity, labeled Qe
(b) If Steverail raised the price above Pm identified in part (a)(i), would total revenue increase, decrease, or not change? Explain.
(c) Assume a per-unit subsidy is provided to Steverail.
(i) Will Steverail’s quantity increase, decrease, or not change? Explain.
(ii) Will consumer surplus increase, decrease, or not change?
(d) Assume instead that a lump-sum subsidy is provided to Steverail. For the short run, answer the following.
(i) Will the deadweight loss increase, decrease, or not change? Explain.
(ii) Will Steverail’s economic losses increase, decrease, or not change?
(a. i) ap 微观经济学真题考查的是only provider(垄断企业)的生产收益情况。作出需求曲线D和MR曲线，由于垄断企业增加产量会有两种效应：需求量增大但是价格降低，所以边际收入是小于价格水平的，因此D曲线在MR的上方。
关于成本曲线，MC曲线形态为先减后增(边际成本特点，边际报酬递减理论)，ATC曲线同样先减后增，并且其最低点为与MC曲线的交点，这是因为当边际成本大于平均成本时，会使平均成本变大;而当边际成本小于平均成本时，会使平均成本变小。
