technology". By separating the production of undesirable outputs from that of desirable outputs, not only do we ensure that … index also provides a meaningful way to decompose environmental productivity into environmental technological and efficiency …

The aim of this article is to study the technology of the sector represented by the Spanish national post-office and …, we analyse economic efficiency (technical and allocative) and scale economies of the production units (cost centres) of … input distance function and the technical and allocative efficiency terms …

. However, the standard cost frontier model yields biased efficiency scores because it ignores technological heterogeneity … between hospitals. In this paper, efficiency scores are derived from a random intercept and an extended random parameter … efficiency according to the standard model gain up to 12 percentage points, serving to highlight the importance of heterogeneity …

technology heterogeneity among large banks in the US We find that failure to consider unobserved technology heterogeneity results … asset size and returns to scale, due to the presence of technology heterogeneity. …

We study the effects of ownership forms on airports' cost efficiency by applying stochastic frontier analysis to a … airports would improve the efficiency of all airports …

Using Bayesian Monte Carlo methods, we augment a stochastic distance function measure of bank efficiency and … majority of banks, productivity growth – the sum of efficiency and technical changes – is negative, implying that the industry … would benefit from innovation. We show that greater technical efficiency is associated with higher profitability, higher …

This paper provides parametric estimates of technical change, efficiency change, economies of scale, and total factor … of the primal Divisia total factor productivity growth index into its three components - technical change, efficiency …
