Measuring Efficiency using a Stochastic Frontier Latent Class Model

Abstract

Efficiency estimation in stochastic frontier models typically assumes that the underlying production technology is the same for all firms. There might, however, be unobserved differences in technologies and input/output qualities that can be inappropriately labeled as inefficiency if such differences are not taken into account. We address this issue by developing Stochastic Frontier Latent Class Model in a “panel data” framework. This model exploits the information contained in the data more efficiently compared to the traditional cluster analysis. An application of the proposed model is presented using Spanish banking data.
