請問一題,有解答但是我想不出來
A、B廠商在同一產業內競爭(價格競爭),假設兩廠商所面對的需求函數如下:
A廠商之需求函數QA=12-APA+2PB
B廠商之需求函數QB=12-4PB+2PA
為簡化分析起見,每家廠商僅付出十元的固定成本,沒有變動成本
而賽局的答案如下
A\B | Nash訂價(PB=2) | 勾結訂價(PB=3)
__________________________________________________________________
Nash訂價(PA=2) | (6,6) | (22,0)
__________________________________________________________________
勾結訂價(PA=3) | (0,22) | (8,8)
(6,6)和(8,8)我求的出來
就Nash均衡,PA=PB=2,QA=QB=8
就聯合訂價,PA=PB=3,QA=QB=6
請問(22,0)和(0,22)怎樣求出
