Stochastic frontier models: a bayesian perspective

TL;DR: In this article, a Bayesian approach to estimation, prediction, and model comparison in composed error production models is presented, where a broad range of distributions on the inefficiency term define the contending models, which can either be treated separately or pooled.
Journal ArticleDOI

Bayesian efficiency analysis through individual effects: Hospital cost frontiers

TL;DR: This paper develops Bayesian tools for making inferences about firm-specific inefficiencies in panel data models using Monte Carlo integration or Gibbs sampling to study the influence of the particular priors used on the firm effects.
Journal ArticleDOI

Modeling and Inference with υ-Spherical Distributions

TL;DR: In this article, a new class of continuous multivariate distributions on × ∈ ℜ n is proposed, called υ-spherical distributions, which generalize the classes of spherical and l q -spherical (when υ(·) is the l 2 norm) distributions.
Journal ArticleDOI

On the use of panel data in stochastic frontier models with improper priors

TL;DR: In this article, a Bayesian analysis of the stochastic frontier model with composed error is presented, and the existence of the posterior distribution and posterior moments is examined under a commonly used class of (partly) noninformative prior distributions.

Posterior analysis of stochastic frontier models using Gibbs sampling

TL;DR: It is shown how Gibbs sampling methods can greatly reduce the computational difficulties involved in analyzing stochastic frontier models with composed error.
