摘要：

This paper analyzes the relationship between market structure and welfare by developing a model of monopolistic competition in which exogenous entry costs and endogenous differentiation costs determine market concentration and market power. A non-monotonic link is identified between these costs and welfare under a decentralized equilibrium. These results detail new reasons why simple market concentration indicators are a misleading statistic for welfare evaluations. (C) 2015 Elsevier B.V. All rights reserved.
