Robust Productivity Measurement: An Econometric Distance Function Approach

在一系列经济分析中需要对生产率进行准确的衡量。例如，在评估微观经济改革的成功时，或在公用事业和运输基础设施公司的价格上限管制中。在这个项目中，我们研究使用计量经济学距离函数作为获得改进的生产力措施的手段。这种新方法解决了替代方法的主要批评，例如生产函数方法中的单一输出限制，价值对偶方法和Törnqvist指数方法中嵌入的优化假设，以及数据包络分析方法的统计噪声批评。

Accurate measures of productivity are required in a range of economic analyses. For example, in the assessment of the success of microeconomic reforms, or in price-cap regulation of utility and transport infrastructure firms. In this project we investigate the use of econometric distance functions as a means of obtaining improved productivity measures. This new approach addresses the main criticisms of alternative approaches, such as the single output restriction in the production function approach, the optimisation assumptions embedded in both the value dual approach and the Törnqvist index approach, and the statistical noise criticism of the data envelopment analysis approach.
