This paper analyzes the pattern of player substitutions during a soccer match, using data from the First Division (Primera División) of the Spanish National Soccer League in the 2004-2005 season. To do so, an inverse Gaussian hazard model is adopted to analyze the first substitutions of each...

In this paper we estimate the total factor productivity of UK airports using a Malmquist index. Productivity change is factored into an index of efficiency change and an index of technological change. Technological change is further decomposed into indexes that measure the bias in the production...

In this paper, the innovative random stochastic frontier model is used to estimate the technical efficiency of UK airports. These airports are ranked according to their total productivity for the period 2000-2005 and homogenous and heterogeneous variables in the cost function are disentangled,...

This paper examines the technical efficiency of Argentinean pension funds management companies using a random stochastic frontier model to rank the pension funds management companies, taking into account heterogeneity in the data. The empirical findings reveal that efficiency measures have a...

This paper analyses the duration of flight delays at Spanish airports. To do so, several hazard models are adopted to take into account the delays observed. The results show that the most important factors are certain airport characteristics and contextual characteristics. The policy...

In this paper, we analyze efficiency and productivity of Italian and Portuguese airports, by using the directional distance function and the Luenberger productivity indicator. The key advantage of this approach is that both input contraction and output expansion are considered. The model...

This paper identifies different groups in a cost function framework of thermo energy plants belonging to EDP-Electricity of Portugal. In particular, we have clustered the sample - comprising data for years 1987 to 2006 - into two groups. To do so, we have implemented a stochastic frontier latent...

This study uses the Bootstrap methodology to measure the productivity changes of US airports with a Malmquist index, from the 2002-2007 adopting the Gillen and Lall (1997, 2001) approach. The results are mixed for the sample of airports analyzed. The study relates the results to the current and...

This paper proposes a framework for benchmarking European co-operative banks and the rationalization of their operational activities. The analysis is based on the Luenberger productivity indicator. A key advantage of this method is that it allows for both input contraction and output expansion...

This paper analyzes 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, Arias and Greene (2004) frontier model is used. These airports are ranked according to their...
