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 analyses the technical efficiency of Portuguese hospitals from 1997 to 2008 with the latent class frontier model, enabling the identification of different segments in the cost frontier. It is found that there are three statistically significant segments in the sample, leading to the...

In this paper, we examine the determinants of low-wage employment in Portugal. For this purpose, we use a data file of the European Community Household Panel (ECHP) for the years 1998 and 1999. In order to take into account unobserved heterogeneity in the data, a random-parameter logit model is...

We analyze the efficiency and productivity growth of a representative sample of Portuguese hospitals from 1997 to 2004, using an innovative approach by employing the directional distance function and the Luenberger productivity indicator. The primary advantage of our approach is that both input...

This paper seeks to analyse the relationship between wages and education at a European level, using a quantile regression in order to be able to extend the study along the whole wage distribution. This analysis is carried out for a sample of 14 European countries (Austria, Belgium, Denmark,...

Transportation, energy and environmental tax reforms represent an ongoing debate in contemporary policy. The main aim of this paper is to shed some light on this debate using micro-simulation tools to analyse consumer response and welfare effects of environmental policy consisting of an...

This paper examines the size o inter-regional wage dispersion in Portugal. For this purpose, we estimate a Mincer-type human capital wage equation, including controls for a large number of regions, and calculate a weighted and adjusted standard deviation (WASD) of inter-regional wage...
