Microeconomics of Agricultural Grading: Impacts on the Marketing Channel
用自保护模型分析分级价格如何影响食品营销系统中产品转化技能的供给，发现资源分配可能互补且不确定性会抑制行业扩张，为农业推广人员的作用提供理论依据。
Abstract In this paper I focus on how grade prices affect the provision of product transformation skills in the food marketing system. A self‐protection model is used to show how resources are allocated to protect the potential value of commodities in the marketing channel. Resource allocations may be complementary, and complementarity may be exploited to expand an industry. Further, uncertainty concerning skill levels may inhibit expansion. Because two primary objectives of agricultural extension involve facilitating skill acquisition and disseminating market information, the model confirms roles for extension personnel. The optimal location of transformation skills in a sequence of operations is also studied.
