Alternative Technical Efficiency Measures : Skew, Bias, and Scale
Feng, Qu - 2011
In the fixed-effects stochastic frontier model an efficiency measure relative to the best firm in the sample is universally employed. This paper considers a new measure relative to the worst firm in the sample. We find that estimates of this measure have smaller bias than those of the...
