In this paper we analyze the levels of technical efficiency and productivity growth attained by Spanish insurance companies during a period of deregulation. We compute Malmquist productivity indexes using the estimates of parametric distance function for several specialized insurance branches....

Malmquistindexes of productivity are generally estimated using index numbertechniques or non-parametric frontier approaches. The aim ofthis paper is to show that Malmquist indexes can be estimatedin a similar way using parametric-deterministic or parametric-stochasticfrontier approaches. To...

En Belgique, une proportion importante de travailleurs quittent la vie active avant d'atteindre l'âge de 60 ans. Dans cette étude nous analysons les conditions de vie de cette tranche de la population à l'aide d'une série d'indicateurs. Il apparaît que plus d'un quart d'entre eux sont...

We simulate different reform scenarios of the Belgian pension system using a micro-simulation approach. Using a rich administrative dataset with extensive information on individual earnings histories, we evaluate the impact of the scenarios for the individuals as well as the system as a whole....

The quality of electricity distribution is being more and more scrutinized by regulatory authorities, with explicit reward and penalty schemes based on quality targets having been introduced in many countries. It is then of prime importance to know the cost of improving the quality for a...

The aim of this paper was to use a parametric stochastic frontier approach (coming from the economic literature) to explore the impact of the concept of activity (taken in a broad sense: i.e., including both professional and non-professional activities) on the constitution and the care of...

L’objectif de cette étude est de montrer l’influence du système de retraite sur la cessation d’activité. La première étape consiste à estimer les incitations financières implicites à ce système et ensuite à les introduire comme variables explicatives du départ à la retraite...

Monte-Carlo experimentation is a well-known approach to test the performance of alternative methodologies under different hypothesis. In the frontier analysis framework, whatever parametric or non-parametric methods tested, most experiments have been developed up to now assuming single output...
