A Comparative Analysis of Productivity Change in Italian and Portuguese Airports

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 generates efficiency scores, ranking the airports in the sample. We conclude that inputs and outputs play a major role in airports efficiency. According to this methodology, it can be stated that some Italian and Portuguese airports are efficient and that productivity increased in most of the cases.Italian and Portuguese airports; Luenberger productivity indicator.

Exact Relations between Four De?nitions of Productivity Indices and Indicators

Generalizing 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.Malmquist and Hicks-Moorsteen productivity indices, Luenberger and Luenberger Hicks-Moorsteen productivity indicators, approximate relation, exact relation

Productivity Growth and Biased Technological Change in Hydroelectric Generating Dams

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 a picture of mixed productivity performance in the Portuguese energy sector. In a second step, we analyse the na- ture of this technical change by using the recent concept of parallel neutrality (Briec et al., 2006). We observe a global shift in the best practice frontier as well as evidence of input bias in technical change.hydroelectric energy; Portugal; Luenberger productivity indicator; parallel neutrality.

A Note on Productivity Change in European Co-operative Banks: The Luenberger Indicator Approach

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 determining relative efficiencies and productivity changes. Benchmarks are provided for improving the operations of those banks which perform worse than others. Several interesting and useful managerial insights and implications arise from the study. The general conclusion is that, between 1996 and 2003, productivity increased for the majority of European co-operative banks analyzed.Europe; Co-operative banks; Luenberger productivity indicator.

Heterogeneity in Technical Efficiency of the French Urban Transport: 1995 to 2002

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 a major role in transport efficiency and we find that the efficiency scores vary along the sample. Policy implication is derived.Urban Transport; France, Translog random Frontier Model and Decision-Making Unit.

A Luenberger index for the Greek life insurance industry

This paper uses the Luenberger productivity index to evaluate the productivity changes of Greek Life insurance companies between 1994 and 2003, combining operational and financial variables. It is found that the average annual productivity change was about 19% and was due to technological progress, whereas the impact of efficiency was minimal. It seems that deregulation, established by the Third Insurance Directive in 1994, provoked investments in new technologies which were not matched by superior managerial practices. For comparative purposes, a Malmquist productivity index is estimated.peer-reviewe

An Econometric Model of Tourism Demand in France

This case study gives an overview of the tourism demand in France by using an econometric model. The study covers the period between 1975 and 2003. Five developed countries have been selected, and the choice of the countries is based upon the fact that continuous data on all relevant variables are available only for those countries. The results show a positive relationship between tourist expenditures and generating country GDP, and a negative relation between tourist expenditures and relative prices

Allons-nous vers une société plus responsable grâce à la pandémie de Covid-19 ?

La question traitée dans cet article porte sur le monde d’après la pandémie... Représente-t-elle un moment décisif qui va nous faire basculer vers une société plus responsable sur les plans sociaux et environnementaux ? De nouvelles habitudes et de nouveaux comportements responsables vont-ils se mettre en place de manière durable ? Pour répondre à ces enjeux, cet article mobilise des théories plurielles associées aux changements d’habitudes. Des préconisations s’adressant autant aux entreprises, qu’aux décideurs publics ou citoyens sont proposées pour dessiner les contours d’un après-Covid-19 socialement et écologiquement plus acceptable
