ABSTRACTGeneralizing earlier approximation results, we establish exact relations between the Luenberger productivity indicator and the Malmquist productivity index under rather mild assumptions. Furthermore, we show that similar exact relations can be established between the Luenberger–Hicks–Moorsteen indicator and the Hicks–Moorsteen index.

We employ the Luenberger productivity indicator to estimate productivity growth and its decomposition into technical change and efficiency change components for savings banks sectors in ten EU countries between 1996 and 2003. The Luenberger indicator requires less restrictive assumptions than standard non-parametric productivity indexes, and it allows the assumption of profit maximisation to be made for sample firms. We estimate average productivity growth in the savings banks sector to be 2.78 percent per annum and driven almost entirely by technical change. Whilst the general results confirm earlier findings, this study is one of the earliest to identify cross-border differences in productivity growth in the savings banks sector.

AbstractThis paper analyses technical efficiency in Angolan banks from 2005 to 2010 with an innovative production frontier model, themodel. The intermediate approach is adopted. It is observed that the efficiency increases over the observation period, according to the international experience, market share and local markets. Policy implications indicate that competition and governance should be promoted in order to increase efficiency.

"This article analyses how long former university students stay unemployed, when searching for the new employment after leaving of the French higher education. Cox duration models are used to account for the proportional hypothesis. The main result of this paper is that the worker's recruitment is based more on the choice of the faculty of initial training than the educational level attainment. Some policy implications are derived from our results to give some recommendations for individual job search and policy-makers in education." [author's abstract]

In this paper, the innovative two-stage procedure of Simar and Wilson (2007) is used to estimate the efficiency determinants of Portuguese hotel groups from 1998 to 2005. In the first stage, the hotels' technical efficiency is estimated with DEA in order to establish which hotels have the most efficient performance. These could serve as peers to help improve performance of the least efficient hotels. In the second stage, the Simar and Wilson model is used to bootstrap the DEA scores with a truncated regression.
The paper contributes to the hotel industry literature by adopting a somewhat novel approach that has never been applied to this industry despite its managerial implications. The motivation for the analysis lies in the fact that during the period under analysis Portuguese hotels faced a number of threats. Knowing what the best practices are is then good news for managers and institutions.

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 contractions and output expansions are considered. Our model generates a productivity indicator that is decomposed into the usual constituents of productivity growth: technological change and efficiency change. The results show that, on average, Portuguese hospitals did not experience productivity growth during the period analyzed. In addition, the incidence of positive productivity growth across Portuguese hospitals was remarkably low.
