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 paper evaluates the production activities of Japanese airports by using a finite mixture model that allows controlling for unobserved heterogeneity. In doing so, a stochastic frontier latent class model, which allows the existence of different technologies, is adopted to estimate production...

This study examines the time series behaviour of oil production for OPEC member countries within a fractional integration modelling framework recognizing the potential for structural breaks and outliers. The analysis is undertaken using monthly data from January 1973 to October 2008 for 13 OPEC...

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...

In this paper, the random stochastic frontier model is used to estimate the technical efficiency of Japanese airports, with regulation and heterogeneity included in the variables. The airports are ranked according to their productivity for the period 1987–2005 and homogeneous and heterogeneous...

This article analyses regulation, ownership and unobserved managerial ability as factors affecting the performance of a representative sample of European airports by means of frontier models. The Alvarez et al. (2004) frontier model is used. These airports are ranked according to their technical...

This article analyses the determinants of banks' profitability in the Portuguese banking sector during the period 1990 to 2005. The study extends the established literature on modelling the banks'k performance by applying a Fourier approximation in order to detect for possible nonlinearities...

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...

A two-stage procedure is used to estimate the technical efficiency of Argentina's airports from 2003 to 2007, a period of intense economic crisis, during which the traffic fell by 50%. In the first stage, the airports' relative technical efficiency is estimated using data envelopment analysis to...

This study examines the degree of time persistence in U.S. disaggregated renewable energy consumption (hydropower, geothermal, solar, wind, wood, waste, and biofuels) using innovative fractional integration and autoregressive models with monthly data for the period 1994:2 to 2011:10. The results...
