Endogenous Commodity Policies and the Social Benefits from Public Research Expenditures
分析政府调整商品政策时，公共农业研究支出的社会收益如何变化，通过三种政府决策模型和两个政策案例，说明放松政策固定假设会改变研究收益的结论。
Abstract Standard analyses of social benefits of public agricultural research expenditures in the presence of commodity policies take the commodity policy as fixed. In reality governments adjust commodity policy levels when the research has important income distributional effects. We use two examples of commodity policies to analyze the consequences of endogenizing commodity policies under three alternative decision‐making models of government. Relaxing the assumption of fixed commodity policies has important impacts on conclusions regarding the social benefits of research in the presence of commodity policies.
