The Strategic Industry Supply Curve*
提出战略性行业供给曲线概念，描述需求冲击下纳什均衡产量与价格轨迹，将完全竞争下的局部均衡分析扩展到不完全竞争市场，统一处理垄断、寡头及线性供给竞争。
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].
