本文论述了技术效率的估计使用伪面板数据旋转面板数据瑞典种植农，每个单位观察最多四年。农场被分为89个队列，使用其共同的时不变的特性，队列被用作一个单独的单元中的实证分析。整体技术效率低下被分解为持久性和剩余成分。还考虑了一种随时间变化的技术效率低下的替代模型。除了技术无效率外，还得到了规模收益和技术变化的测度。
This paper deals with the estimation of technical efficiency using pseudo panel data constructed from rotating panel data on Swedish crop farmers where each unit is observed for a maximum of four years. Farms are grouped into 89 cohorts, using their common time-invariant characteristics, and the cohorts are used as an individual unit in the empirical analysis. The overall technical inefficiency is decomposed into a persistent and a residual component. An alternative model with time-varying technical inefficiency is also considered. In addition to technical inefficiency, measures of returns to scale and technical change are also obtained.
