Dans l'ouvrage que Van Parijs a consacré en 1995 aux fondements philosophiques et économiques du projet d'allocation universelle, le chapitre IV est dédié au problème du financement « soutenable » d'une telle mesure. Les « rentes d'emploi » y sont présentées comme un troisième type...

We study the effects of pension reform in a four-period OLG model for an open economy where hours worked by three active generations, education of the young, the retirement decision of older workers, and aggregate per capita growth, are endogenous. Next to the characteristics of the pension...

We model how a Beveridgean pay-as-you-go pension system may be supported by a majority of heterogeneous voters in a general equilibrium OLG model. The introduction of heterogeneity creates intragenerational transfers among workers which may lead to different optimal taxation rates within young...

It is usually thought that a Beveridgean pension system redistributes income more than a Bismarckian one, since it ensures replacement ratios that decrease with income. We check the validity of this result when the fact that pension systems can redistribute also through their effects on labor...

Nous considérons un modèle à générations imbriquées en économie fermée avec des travailleurs qualifiés et des travailleurs non qualifiés. Il existe un système de retraite obligatoire qui se décompose en deux branches : une branche avec financement par répartition, cotisations...

Dans un modèle à générations imbriquées avec production «à la Diamond», on introduit de l’incertitude sur la durée de vie. En comparaison la dynamique d’une économie sans système de retraite avec celle d’une économie disposant d’un système de retraite par capitalisation, on...

With an overlapping generations model, Williamson and Jones [1983] demonstrated that the long-run savings ratio in the U.S. was not affected by the introduction and the reform of the unfunded social security system. This paper extends their model by including a production sector, endogenous...

We forecast income growth over the periode 2000-2050 in the US, Canada, and France. To ground the forecasts on relationships that are as robust as possible t changes in the environment, we use a quantitative theoretical approach which consists in calibrating and simulating a general equilibrium...

A transition from pay-as-you-go pension systems to more private funded systems is often suggested as a solution to finance pension systems threatened by ageing. This paper analyses alternative potential remedies linked to changes in labour market characteristics, within an international...

Early retirement is often explained as resulting from a voluntary labour supply choice of a utility maximizing individual. nonetheless, a lof of individuals perceive retirement as a forced instead as a voluntary decision. This paper tries to accomodate voluntary and unvoluntary labour supply...
