Determinants of Agricultural Protection: The Role of Democracy and Institutional Setting Alessandro Olper
研究了1982-1992年间35个国家的民主和制度质量对农业保护的影响，发现保护产权的制度质量是关键决定因素，而民主水平本身作用不大。
This paper deals with the effects of democracy and institutional setting on agricultural protection in 35 developed and developing countries during 1982–1992. Regression analysis is conducted to test the effects of three alternative measures of democracy and two composite indices of the quality of institutions that protect and enforce property rights. After controlling for many other political and economic determinants of agricultural protection, the paper shows that democracy affects protection positively, but it is not the level of democracy per se that seems to matter. On the contrary there is strong evidence that the quality of institutions that protect and enforce property rights is a key determinant of agricultural protection. This empirical result is robust to changes in institutional proxy, country sample and statistical problems.
