Distribution of Research Gains in Multistage Production Systems: Further Results
将Muth单阶段模型中的“营销”部门分解为“加工”和“分销”两个连续阶段，利用比较静态分析推导农民从下游研究中获益的充要条件，发现农场收益关键取决于研究针对的营销阶段。
Abstract The “marketing” sector in Muth's single‐stage model is disaggregated into two sequential stages: “processing” and “distribution.” Comparative statics are used to derive necessary and sufficient conditions for farmers to gain from downstream research. The farm benefits are shown to depend crucially on the stage in “marketing” to which research is directed.
