The Implications of Using Messy Data to Estimate Production-Frontier-Based Technical Efficiency Measures
使用杂乱数据估计基于生产前沿的技术效率：影响与后果
An empirical study of efficiency at the plant level, requiring production and financial data, was done using frontier function specifications. It is not evident from the implementation of the production-frontier models that different methodologies will consistently flag the same observations as being efficient or inefficient. As a result, outlier diagnostics for individual observations and for subsets of observations are used to achieve a relative index of influentiality…
