In this paper, we develop the concept of the strategic industry supply curve, representing the locus of Nash equilibrium outputs and prices arising from additive shocks to demand. We show that the standard analysis of partial equilibrium under perfect competition, including the graphical representation of supply and demand, due to Marshall, can be extended to encompass imperfectly competitive markets. Our approach permits a unified treatment of monopoly, oligopoly and competition in linear supply schedules. Further, our model satisfies the five principles of incidence set out by Weyl and Fabinger [2013].

战略性行业供应曲线*

在本文中，我们提出了战略性行业供应曲线的概念，该曲线代表了纳什均衡产出和价格因需求激增而产生的价格的轨迹。我们表明，完全竞争下的部分均衡的标准分析，包括由于马歇尔而引起的供需关系的图形表示，可以扩展为涵盖不完全竞争的市场。我们的方法允许对线性供应时间表中的垄断，寡头垄断和竞争进行统一处理。此外，我们的模型满足了Weyl和Fabinger [2013]提出的五项发生率原则。
