本文研究了企业倒闭及其对供应链的破坏如何放大负面冲击。我们开发了一个非竞争模型，定制的制造商-客户关系提高生产率，并通过讨价还价划分企业和供应商之间产生的关系特定的盈余。生产率的变化改变了整个经济中剩余的分配，并决定了哪些公司处于失败的边缘。一个公司的失败可能会波及到它的供应商和客户，以及生产网络中其他部分的公司。我们提供了存在性，唯一性，和一系列的比较静态结果，并显示了如何响应的均衡生产网络可能会传播衰退冲击。JEL分类：D57、E23、E32
This paper studies how firm failures and the resulting disruptions to supply chains can amplify negative shocks. We develop a non-competitive model where customized supplier-customer relations increase productivity, and the relationship-specific surplus generated between firms and their suppliers is divided via bargaining. Changes in productivity alter the distribution of surplus throughout the economy and determine which firms are at the margin of failure. A firm’s failure may spread to its suppliers and customers and to firms in other parts of the production network. We provide existence, uniqueness, and a series of comparative statics results, and show how the response of the equilibrium production network may propagate recessionary shocks.
