Le but de l’article est de mesurer les niveaux d’efficacité d’entreprises de transport, urbain et interurbain, de passagers. Le modèle théorique permet de combiner des facteurs simultanément complémentaires et substituables. L’importance des liens de complémentarité entre certains facteurs de production apparaît. Les calculs des niveaux d’efficacité font ressortir l’amélioration des firmes concernées au fil du temps. [less ▲]

L’objet de cet article est d’étudier l’incidence redistributive que devrait avoir la substitution partielle des pensions publiques par des pensions privées, qui favorisent les salaires et les revenus les plus élevés relativement aux salaires et revenus les plus faibles. Dans la mesure où les pensions privées vont se développer, l’article évalue si elles ne vont pas accroître les inégalités dans les tranches d’âge les plus élevées par des simulations effectuées dans le cadre de la Belgique.

This paper studies the effects of variables pertaining to alternative bequest motives on the composition of households' portofolio. It relies on a 1986 survey on the assets structure of 5600 French households. The main conclusion is that bequest motives indeed influence the composition of households' wealth. However, available data does not allow one to sort out the influence of specific models of inheritance. [less ▲]

We estimate a factor requirement frontier for European railways using a panel data approach in which technical efficiency is assumed to be endogencously determined. This approach has two main outcomes. On one hand, it allows the identification of factors influencing technical efficiency, and on the other hand, it allows the estimation of alternative efficiency indicators free of these influences. In the case under study, a particular attention is devoted to an autonomy indicator representing the managerial freedom, with respect to public authorities, experienced by firms, that appears to be positively correlated with technical efficiency.

Cet article se propose d’évaluer l’importance des legs volontaires sur la base d’une enquête de l’Insee sur la structure des actifs financiers de 5 600 ménages. Cette mesure est alors analysée pour voir si elle correspond à nos a priori sur les legs intentionnels et si elle est conforme à quelques modèles d’héritage. [less ▲]

The purpose of this paper is to provide for both life and non life insurance a measurement of economies of scale and an assessment of productive performance of French companies. We use a translog cost function to check the presence of scale economies and a parametric approach to construct our yardstick of productive efficiency. Our panel data covers 84 life and 243 non life companies for the period 1984–89. The main findings indicate both the existence of increasing returns to scale and a wide dispersion in the rates of inefficiency across companies. Those two results are shown to be closely linked to a number of characteristics of the companies studied, particularly their institutional form. [less ▲]
