This paper proposes a two-equation price-wage model that enables to test whether the inflationary pressure on wage rate is only present when the rate of inflation is greater than some threshold value. Since the likelihood function for this model is very nonstandard, we develop a small-sample...

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...

This paper develops Bayesian approaches to deal with linear elliptical regression models that differ in the covariance structure. A pretest method based on posterior model probabilities is compared with a pooling approach, and the data density is defined as a mixture of elliptical densities with...
