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...

In this paper, we analyze the heterogeneity in the technical efficiency of a sample of French urban transport companies with a translog production frontier model. The model generates efficiency disentangling homogenous and heterogeneous variables. Our study concluded that outputs and inputs play...

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 analyses productivity growth and the nature of techni- cal change in a sample of Portuguese hydroelectric generating plants over the period 2001 to 2004. In a ¯rst step, we employ the Luen- berger productivity indicator to estimate and decompose productivity change. The results paint...

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...

In this paper we examine the effects of asymmetric information on the nature of financial equilibrium and on the capital structure of firms. In the first model presented, the financial contracts on offer involve pooling equilibrium with no adverse selection. However, in the special case...

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

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 article analyses the determinants of the length of stay of Portuguese tourists taking vacations in Latin America, based on a questionnaire distributed on flights of a Portuguese charter airline, Air Luxor. A survival model is adopted to measure the relationship between vacation length and...

In this paper we analyse the socio-economic characteristics (e.g. age, gender, education, nationality) associated with the probability of subscribing to an art review, among visitors of the Visual Arts Biennale of Venice taking into account the heterogeneity of the data. The analysis uses a data...
