Measuring Technical and Allocative Inefficiency in the Translog Cost System : A Bayesian Approach

Kumbhakar, Subal C.; Tsionas, Efthymios G. - 2004

In this paper, we propose simulation based Bayesian inference procedures in a cost system that includes the cost function and the cost share equations augmented to accommodate technical and allocative inefficiency. Markov Chain Monte Carlo techniques are proposed and implemented for Bayesian...
