在1994年出版的一本书中，Production Frontiers、Fare和同事开发了一种基于产出的DEA（数据包络分析）技术来计算生产率变化。该技术使用法雷尔效率度量来构建Malmquist指数。法雷尔效率度量是从允许输出约束松弛的线性规划问题中导出的。在效率计算中，输出松弛存在的可能性是不理想的。因此，本文还构建了不考虑产出松弛的Russell和Zieschang效率测度，并将其与Farrell测度进行了比较。该分析使用了1983年至1994年期间日本非寿险公司的数据。
In a book published in 1994, Production Frontiers, Fare and colleagues developed an output-based DEA (data envelopment analysis) technique to compute productivity change. The technique constructs the Malmquist index using Farrell measures of efficiency. The Farrell efficiency measures are derived from linear programming problems which allow slack in output constraints. The possible existence of output slack is less than desirable in the computation of efficiency. Therefore, the present paper constructs also the Russell and Zieschang measures of efficiency, which disallow output slack and compares them with the Farrell measures. The analysis uses data on Japanese non-life insurance firms during the period 1983–94.
