On measuring economic efficiency
提出一个包含生产前沿和要素份额方程的系统，同时测量企业技术效率和投入配置效率，并用菲律宾农业数据验证方法可行性。
Abstract This paper considers a system consisting of a production frontier and factor share equations to measure firm‐specific technical efficiency and input‐specific allocative efficiency simulataneously. In estimating the system as a whole, the joint distribution of all errors in the equations is used. This is more efficient than using the marginal distribution of a function of the errors as one does by estimating either the profit function of the production function alone. The workability of the method is illustrated by applying it to farm‐level data from Philippines agriculture.
