THE ECONOMIC POLITY OF FARM POLICY
评述农业政策的“新政治经济学”，包括政府收入最大化模型、压力集团的集体行动以及政客与选民的互动，并解释为何富国补贴农民而穷国征税。
A review of the ‘new political economy’ of agricultural policies includes models of social income maximising governments, collective action by ‘pressure groups’, and the interaction between politicians and voters. An alternative explanation for Olson's “social by‐product” theory for why farmers received massive subsidies as a large group is also presented. An explanation for various patterns of farm policy interventions is given, including why rich countries subsidise and poor countries tax farmers. Finally, the role of public research expenditures and the interaction with commodity policy is explored.
