Abstract

Firms in many industries engage in corporate social responsibility (CSR). We consider a vertical market with one upstream firm committed to CSR and two downstream firms providing differentiated goods, and analyze the endogenous market structure (Cournot, Bertrand, or Cournot–Bertrand competition) between the downstream firms. Contrary to conventional wisdom, we show that Bertrand competition emerges in the downstream market when the degree of upstream CSR is high. Under Bertrand competition, consumer surplus is larger, and the upstream firm with CSR prioritizes consumer surplus, which results in a lower input price. Consequently, the downstream firms earn higher profits under Bertrand competition.

具有上游企业社会责任的内生市场结构

许多行业的企业都在履行企业社会责任（CSR）。我们考虑一个垂直市场，一个上游企业致力于企业社会责任，两个下游企业提供差异化产品，并分析下游企业之间的内生市场结构（古诺、贝特朗或古诺-贝特朗竞争）。与传统观点相反，当上游企业社会责任程度较高时，下游市场就会出现Bertrand竞争。在Bertrand竞争下，消费者剩余较大，具有CSR的上游企业优先考虑消费者剩余，导致投入价格较低。因此，在伯特兰竞争下，下游企业获得了更高的利润。

期刊介绍： Managerial and Decision Economics will publish articles applying economic reasoning to managerial decision-making and management strategy.Management strategy concerns practical decisions that managers face about how to compete, how to succeed, and how to organize to achieve their goals. Economic thinking and analysis provides a critical foundation for strategic decision-making across a variety of dimensions. For example, economic insights may help in determining which activities to outsource and which to perfom internally. They can help unravel questions regarding what drives performance differences among firms and what allows these differences to persist. They can contribute to an appreciation of how industries, organizations, and capabilities evolve.
