Dans cet article, nous étudions l’impact des différences de longévité sur la conception des politiques publiques, en particulier celles liées au départ à la retraite. Nous montrons premièrement qu’alors même que l’espérance de vie a augmenté de manière très importante tout au...

This paper analyzes and compares the macroeconomic performance of defined-benefit and defined-contribution pay-as-you-go pension systems when population ages. When the fertility rate decreases or longevity rises, it is shown that a shift from defined benefit (defined total benefit or defined...

Although the optimal policy under endogenous fertility has been widely studied, the optimal public intervention under endogenous childbearing age has remained largely unexplored. This paper examines the optimal family policy in a context where the number and the timing of births are chosen by...

This paper shows how the role of the market, the state and the family in providing financial support at old age has evolved over time with changes in factors such as the reliability and the effectiveness of family support, the rate of interest, the cost of public funds and earning inequality. We...

Derived pension rights exist in most Social Security systems but with variable generosity. They are mainly targeted towards non-working wives and widows and are viewed as a means to alleviate poverty among older women living alone. The purpose of this paper is to explain how they can emerge from...

We study the optimal design of a social security system when individuals differ in health status and occupation. Health status is private information but is imperfectly correlated with occupation: individuals in harsh occupations are more likely to be in poor health. We explore the desirability...

One of the greatest success stories in our societies is that people are living longer, life expectancy at birth being now above 80 years. Whereas the lengthening of life opens huge opportunities for individuals if extra years are spent in prosperity and good health, it is however often regarded...

This paper studies the optimal linear pension scheme when society consists of rational and myopic individuals. Myopic individuals have, ex ante, a strong preference for the present even though, ex post, they would regret not to have saved enough. While rational and myopic persons share the same...

This paper shows that the combination of habit formation – present consumption creating additional consumption needs in the future – and myopia may explain why some retirees are forced to "unretire", i.e., unexpectedly return to work. It also shows that when myopia about habit formation...

In this paper we study the optimal design of a long term care policy in a setting that includes three types of care to dependent parents: public nursing homes, financial assistance by children and assistance in time by children. The instruments are public nursing homes and subsidies to aiding...
