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 study analyses the persistence in the international monthly arrivals to the Azores Islands using a model based on fractional integration and seasonal autoregressions. The estimated fractional differencing parameter gives an indication of the long run evolution of the series. We use both...

This study applies the Dynamic Slacks Based Model (DSBM) developed by Tone and Tsutsui (2010) in order to assess the evolution of input saving/output increasing potentials in major Brazilian Banks from 1996 to 2011. We propose that these potentials or slacks can be used as proxies for an...

This paper presents an efficiency assessment of selected OECD countries using a Slacks Based Model with undesirable or bad outputs (SBM-Undesirable). In this research, SBM-Undesirable is used first in a two-stage approach to assess the relative efficiency of OECD countries using the most...

This paper analyses technical efficiency in French airports from 2005 to 2008 with the inverse B-convex model. This methodology is adopted permitting to relax the traditional convexity hypothesis common in DEA (data envelopment analysis) literature. The policy implications of the study is that...

This article analyses the efficiency of French nuclear energy plants belonging to EDF-electricity of France from 2004 to 2008 with a DEA-Data Envelopment Analysis model. The <inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" id="ILG0001" xlink:href="raec_a_892199_ilg0001.gif"/>-convexity model is used to investigate the technical efficiency of a representative sample of nuclear plants. The results...

This paper analyses the nature of technical change in the French labour market. Data Envelopment Analysis (DEA) is adopted to investigate productivity change in a sample of higher education leavers over the period 1999 and 2004. In a first step, the Luenberger Productivity Indicator (LPI) is...

This paper analyses house prices in Spain and Portugal over the last twenty years. In recent decades, housing prices have increased dramatically in the two countries; However, in 2007 the US subprime mortgage crisis broke out, which had worldwide influences, including Spain and Portugal. The...
