Political Institutions and International Patterns of Agricultural Protection
分析政治制度和权利如何影响不同商品、国家及时间上的农业保护模式，发现多元制度与更高保护水平相关，但呈非线性关系。
This paper analyzes the influence of political systems and rights in patterns of agricultural protection across commodities, countries, and over time. Four political systems and a qualitative index of political rights account for differences in political institutions. The analysis incorporates the effects of development, of constraints on tax collection feasibility, and of comparative advantages and terms of trade. Pluralistic systems are associated with higher agricultural protection levels, although in a nonlinear fashion. Access to pluralism appears to be important, although further democratization partly dissipates protection. Copyright 1994 by MIT Press.
