Managerial form, ownership and efficiency: a case-study of Argentine agriculture
利用阿根廷数据，研究了管理类型、所有权集中度和监督机制对农业效率的影响，发现这些因素对营销效率的影响大于对技术或成本效率的影响。
In agriculture, studies dealing with the separation of ownership from control have focused on sharecropping, paying little attention to the impact of management and ownership on efficiency. Using Argentine data, this study tests the hypothesis that efficiency is a function of type of management, concentration of ownership, and mechanisms for monitoring managers. Results show that management, ownership and monitoring have a greater impact on marketing efficiency than either on technical or cost efficiency.
