| 摘 要： | 研究了在行动时机(先动还是后动)和策略变量类型(价格还是产量)都由参与人内生确定的双重内生选择下双寡头博弈的均衡,表明无论参与人在内生时机之前还是内生时机之后选择策略变量的类型,博弈的均衡结果是相同的,都为三种可能行动顺序的产量竞争,即同时行动和分别以两参与人为领头者的序贯行动的产量竞争。

| Abstract: | This paper studies the equilibrium outcomes of a duopoly game under double endogenous choices,i.e.both the strategic variables(price or quantity)and the move-timing(first-mover or second mover)are chosen endogenously.It is showed that,whether the strategic variables are chosen before or after endogenous timing,the equilibrium out comes are identical.The equilibrium outcomes are quantity competitions with three kinds of move orders,i.e.one simultaneous-move game and two sequential-move games with both leader-follower configurations. |
