问题如下:
Upsilon Natural Gas, Inc. is a monopoly enjoying very high barriers to entry. Its marginal cost is $40 and its average cost is $70. A recent market study has determined the price elasticity of demand is 1.5. The company will most likely set its price at:
选项:
A.$40.
B.$70.
C.$120.
解释:
C is correct.
Profits are maximized when MR = MC. For a monopoly, MR =P(1-1/|E|) Setting this equal to MC and solving for P:
$40 = P[1 – (1/1.5)] = P × 0.333
P = $120
考题:利润最大化
解析:本题直接考察利润最大化,
直接套用公式,MR =P(1-1/|E|) ,代入数据得:
$40 = P[1 – (1/1.5)] = P × 0.333
P = $120
利润最大化为什么不是 MC = MR?
