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 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...

This paper re-examines the effects of population aging and pension reforms in an OLG model with labor market frictions. The most important feature brought about by labor market frictions is the connection between the interest rate and the unemployment rate. Exogenous shocks (such as aging)...

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...

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...

Empirical papers show that labor income and capital income are differently taxed all over the world. We investigate whether this may correspond to individual preferences. We tackle this question in an overlapping generations general equilibrium model with heterogeneous agents: young versus old...

Two social security schemes are compared in the long run, one based on a basic income and on the other on unemployment benefits. The analysis is carried out in an overlapping generations model in which agents have to decide whether to become skilled or remain unskilled, and how much time to...
