Technical efficiency and farm size: a conditional analysis
研究了技术效率与农场规模的关系，通过控制变量分析发现技术效率影响利润最大化生产者的投入需求和产出供给，基于西班牙奶牛场面板数据。
The relationship between technical efficiency and size might be affected by farm heterogeneity. We analyse this relationship conditional on a set of control variables. These control variables are chosen using a production model where technical efficiency is introduced as a parameter. As a result, technical efficiency affects both the input demand and the output supply of a profit maximising producer. The empirical application explores these issues using panel data of dairy farms in Spain.
