  (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。

  由于企业economic losses,所以ATC曲线在D曲线上方,处于亏损状态。当MR=MC时,相对最优,因为边际成本小于边际收入时,增大产量会使企业获利;而边际成本大于边际收益时,企业不会增大产量。交点X轴坐标为Qm,Y轴坐标为Pm。
