This paper analyses technical efficiency of European banks over the period 1996-2003 with unbalanced panel data techniques. A latent class frontier model is used which allows the identification of different segments in the production frontier. We find that there are three statistically...

This article introduces the Data Envelopment Analysis (DEA) bootstrap procedure to analyze the technical efficiency of Brazilian first league football clubs. For comparison purpose the study also estimates the efficiency scores with the traditional DEA model. From the results, it is clear that...

This paper analyzes the cost efficiency of Brazilian first league soccer clubs using a Bayesian Varying Efficiency Distribution (VED) model. We confirm that the model fits the data well with all coefficients correctly signed and in line with the theoretical requirements. From the efficiency...

This study analyses and compares the cost efficiency of Japanese steam power generation companies using the fixed and random Bayesian frontier models. We show that it is essential to account for heterogeneity in modelling the performance of energy companies. Results from the model estimation...

This article looks at the efficiency of Portuguese tour operators focusing on firm size, group ownership, and mergers and acquisitions. It has been argued that changed market conditions in Europe make it hard for tour operators to achieve economies of scale and market growth without increasing...

This paper employs the two-stage procedure of Simar and Wilson (2007) to analyse the effects of deregulation on the efficiency of the Greek insurance industry. The efficiency is estimated by means of data envelopment analysis (DEA). The companies are ranked according to their CRS efficiency...
