The authors consider a Bayesian implementation of a new approach to estimating demand systems. This approach, suggested by Hal R. Varian (1990), is based on a generalization of Sidney Afriat's (1967) efficiency index. The model the authors propose leads to a very tractable posterior and...

In this paper we describe the use of modern numerical integration methods for making posterior inferences in composed error stochastic frontier models for panel data or individual cross- sections. Two Monte Carlo methods have been used in practical applications. We survey these two methods in...
