AGRICULTURAL POLICIES IN OECD COUNTRIES: WHAT CAN WE LEARN FROM POLITICAL ECONOMY MODELS?
回顾政治经济学文献解释经合组织国家农业政策的能力，探讨保护的正向理论如何为规范政策分析提供信息，并指出政策内生性认识的三项重要功能。
The ability of the political economy literature to explain agricultural policies in OECD countries is reviewed, with a view to discerning how positive theories of protection can inform normative policy analysis. Recognition of the endogeneity of agricultural policy is seen to serve three important functions. First, it lays bare the fundamental constraints under which policymakers operate. Second, it implies a revision of the traditional calculus of welfare effects. Third, it may help reduce Downsian “rational ignorance” with respect to both policy causes and policy consequences. Whilst the literature suffers from practical limitations, political economy insights may form the basis for interdisciplinary research into the effects of procedural reform.
