Inference in stochastic frontier analysis with dependent error terms

Technical Efficiency of Teaching Hospitals in Iran: The Use of Stochastic Frontier Analysis, 1999–2011

Background Hospitals are highly resource-dependent settings, which spend a large proportion of healthcare financial resources. The analysis of hospital efficiency can provide insight into how scarce resources are used to create health values. This study examines the Technical Efficiency (TE) of 12 teaching hospitals affiliated with Tehran University of Medical Sciences (TUMS) between 1999 and 2...

Comparative Analysis of Stochastic Frontier Partially non-parametric and Stochastic Frontier Parametric Methods Case Study: Measuring Cost Efficiency in Wheat Production in Iran

A double-copula stochastic frontier model with dependent error components and correction for sample selection

In the standard stochastic frontier model with sample selection, the two components of the error term are assumed to be independent, and the joint distribution of the unobservable in the selection equation and the symmetric error term in the stochastic frontier equation is assumed to be bivariate normal. In this paper, we relax these assumptions by using two copula functions to model the depend...

Maximum likelihood estimation of stochastic frontier models by the Fourier transform

The paper is concerned with several kinds of stochastic frontier models whose likelihood function is not available in closed form. First, with output-oriented stochastic frontier models whose one-sided errors have a distribution other than the standard ones (exponential or half-normal). The gamma and beta distributions are leading examples. Second, with input-oriented stochastic frontier models...

Determination of Technical Efficiency of Intensive Care Units in Hospitals Afilliated to Kerman University of Medical Sciences by Stochastic Frontier Analysis in 2008

Background & Aims: Hospitals are the most important centers that provide health services in the country. They have to use scientific and efficient management at all levels for promoting health. Intensive care units (ICU) are one of the most sensitive parts of the hospitals; therefore, paying attention to its efficiency is of particular importance. The purpose of this paper was to estimate the t...
