Endogenous trade policy and lobby formation: an application to the free-rider problem

Abstract

This paper develops a model in which tariffs are determined through bargaining between a utility maximizing policy maker and an industry lobby. Individual firms only contribute to the lobbying effort if it is in their own self-interest so that both trade policies and lobby formation are endogenous. By introducing bargaining between the industry and the government, the paper provides microfoundations for the tariff-formation function approach taken by many authors in the political economy literature. Applied to the free-rider problem, the model identifies general conditions under which increasing the number of firms in an industry makes cooperation between them more difficult.
