Statistical inference for the Russell measure of technical efficiency: Journal of the Operational Research Society: Vol 71, No 3

Abstract

Abstract

Data envelopment analysis (DEA) has become a popular approach to nonparametric efficiency measurement. The statistical inference using bootstrap methods is readily available for the radial DEA estimator; however it is missing for the Russell measure, the nonradial DEA estimator. We propose a bootstrap based procedure for making statistical inference about the individual Russell measures of technical efficiency. We perform simulations to examine finite sample properties of the proposed estimator. Finally, we present an empirical study using proposed bootstrap procedure.

Keywords: Nonradial efficiency, Russell measure, data envelopment analysis, frontier efficiency models, statistical inference, bootstrap

Notes

1 Though we do not directly set the correlation between λ₁ and λ₂, our experiments with different constellations gave us a sense that setting the correlation between λ₁₀ and λ₂₀ directly influenced the correlation between λ₁ and λ₂.
