Diseconomies of Size with Fixed Managerial Ability
通过生产模型和奶牛场数据，证明在管理能力固定时扩大农场规模会导致利润下降，为农场主和农业政策制定者提供了规模不经济的实证依据。
Abstract Managerial ability has important implications for farm growth. In this article we first show in a production model that increasing output with a fixed level of managerial ability can lead to a decrease in profits. Next, we discuss the effect that managerial ability has on economies of size. In the empirical part, economies of size are estimated for a sample of dairy farms using a proxy for managerial ability, which is calculated as a technical efficiency index. The results show that increasing farm size while holding managerial ability constant can be an important source of diseconomies of size.
