Modelling Policy Issues in a World of Imperfect Competition
讨论当企业具有市场势力时，如何为寡头企业设定目标函数，特别是基于利润和股东总需求的真实财富最大化概念，为分析不完全竞争下的政策问题提供概念基础。
General equilibrium theory constitutes a sound basis for the discussion of policy issues if firms do not have market power. However, if firms influence prices strategically, the concept of profits loses its meaning due to the price normalization problem. Hence, it is unclear how to model the behavior of oligopolistic firms. In order to provide a conceptual foundation for the analysis of policy issues in the case of imperfect competition, we discuss ways to formulate the objective of a strategic firm. In particular, we investigate the concept of real wealth maximization that is based on profits as well as on shareholders' aggregate demand.
