标题[考试] Bertrand均衡模型
时间Fri Feb 8 12:04:04 2008
来源: 政大贸研
科目: Supposed that A anDd B each operate under condition of constant average
and marginal cost, but that MCa = 10, MCb = 8. The demand for the
firm's is given by Q = 500-20P. What is the profit for each firm?
问题: 因为MCa = 10 > MCb = 8
所以厂商B可以掠夺整个市场
因此在Bertrand下的均衡为 : 8 ≦ p < 10, 300 < Q ≦ 340
但为什麽厂商B的利润会是
0 ≦ π < 600
600是怎麽算出的阿??
烦请版友帮忙
