Bertrand均衡模型 - 經濟

來源: 政大貿研

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?

問題: 因為MCa = 10 > MCb = 8

所以廠商B可以掠奪整個市場

因此在Bertrand下的均衡為 : 8 ≦ p < 10, 300 < Q ≦ 340

但為什麼廠商B的利潤會是0 ≦ π < 600

600是怎麼算出的阿??




煩請版友幫忙
