[考試] 研究所考古題請教
來源: 98 高應大
科目:經濟學
問題:
7.Suppose for some firm that average total cost is minimized at Q1 units of
output. For a monopolistically competitive firm in long-run equilibrium,
Q1
A.is also the level of output at which marginal cost equals average total
cost.
B.exceeds the level of output at which there is a point of tangency between
the demand curve and the average total cost curve.
C.exceeds the level of output at which marginal revenue equals marginal cost.
D.All of the above are correct.
想法：獨占性競爭廠商產量會低於完全競爭廠商，因為在AC下降的地方生產，而不是
在AC最低點 ? 裡面似乎沒有這個選項 ?
13.For a monopolist , marginal revenue is
A.positive when the demand effect is greater than the supply effect.
B.positive when the monopoly effect is greater than the competitive effect
C.negative when the price effect is greater than the output effect .
D.negative when the output effect is greater than the price effect.
想法：需求效果 ? 供給效果 ? 獨占效果? 競爭效果? .....獨占有這些效果 ?
還是我會錯意了 @@?
麻煩各位先進了..
謝謝 !!!
