The aim of this paper is to compare the empirical results from three alternative parametric efficiency models using rank-sum test statistic. The comparison involves the technical efficiency scores and their hospitals ranking of the following models: a) Battese and Coelli (1992); b) technical...

This paper presents estimates of technical efficiency for Greek public hospitals using a non-neutral stochastic production frontier. In particular a translog production frontier is estimated for a panel data of 105 public hospitals over the period 1992-93. The estimated efficiency is found to be...

The recurring heavy precipitations which have struck the south of France these last few years highlight that the affected cities have little pertinent information on how to manage these emergencies, and therefore appear powerless. In response, the development of a local emergency operations plan...

This paper proposes an alternative model for separating technical change from time-varying technical inefficiency. The proposed formulation uses the general index, developed by Baltagi and Griffin (1988), to model technical change in the production frontier function and a quadratic function of...

This paper presents a procedure for measuring technical and allocative inefficiency in an input distance function framework. The procedure involves solving a system of equations to compute the unobserved cost minimizing input vector that is used to compute the cost of allocative inefficiency....

This paper represents a dynamic specification of the Almost Ideal Demand System (AIDS) based on recent developments on cointegration techniques and error correction models. Based on Greek meat consumption data over the period 1958-1993, it was found that the proposed formulation performs well on...

In this paper we develop radial and directional measures of the rate of technical change for the class of directional distance functions. For both types, we distinguish between primal and dual measures while the former are further divided into oriented (input- and output-based) and non-oriented....
