不对称信息条件下的纵向约束述评

A Review of Vertical Restraints Under Asymmetric Information

在现代产业组织理论中,纵向约束是指上下游企业之间对价格、数量或者服务水平进行约束的长期契约关系。纵向约束理论从20世纪80年代中期才逐渐发展起来,早期的纵向约束文献多集中于如何利用纵向约束消除外部性,而当前纵向约束研究的重点是在不对称信息条件下的纵向约束问题。本文回顾了纵向约束理论发展沿革,重点对四个经典的不对称信息条件下纵向约束模型进行了述评。

Among modern industrial organization theory,vertical restrains are a series of longterm contracts between upstream and downstream firms,which re- strict some variables such as prices,quantity,and service level.Vertical restraints theory developed gradually in middle 1980s.The emphasis of early literatures was how to use vertical restraints to eliminate externality,while now the research has focused on vertical restraints under asymmetric information.This paper is a survey of the evolution of vertical restraints theory,and especially a review of four vertical re- straints models under asymmetric information.
