This paper presents a model where young and old workers compete for one type of jobs in the presence of retirement opportunity. Within this framework, we show that increased retirement opportunities (such as early retirement) has most of the time a depressing impact on the unemployment rate. Indeed the number of vacancies posted by firms is influenced by the probability that an old worker is going into retirement. We show that the degree to which younger workers are influenced by retirement of older workers depends on the relative productivity of young and older workers. It is only when older workers are much more productive than young workers that retirement may benefi t to unemployment. [less ▲]

Les effets redistributifs des systèmes de retraite en Europe

Les systèmes de retraite varient d’un pays à l’autre de l’Union Européenne selon différentes caractéristiques. Mais tous effectuent une certaine redistribution au sein des cohortes d’individus. Cet ... [more ▼]

Les systèmes de retraite varient d’un pays à l’autre de l’Union Européenne selon différentes caractéristiques. Mais tous effectuent une certaine redistribution au sein des cohortes d’individus. Cet article compare les performances redistributives intragénérationnelles des retraites publiques en utilisant les données du Luxembourg Income Study. L’analyse montre qu’il existe une grande variabilité entre les pays mais que ces différences peuvent être expliquée en partie par les caractéristiques propres aux systèmes. Il est aussi démontré que la redistribution ne favorise pas l’ensemble de la population retraitée de la même manière et que les femmes les plus âgées constituent la catégorie la moins favorisée.

The purpose of this article is to distinguish between two types of generosity of the welfare state towards the elderly. These are: average generosity and generosity towards the poor. We compare these indicators across about 20 countries and show how they relate to each other. In particular, we show that a social protection system that is contributive benefits from a large political support and tends to be generous towards the poor. [less ▲]

Political resistance to a progressive increase in the retirement age is widespread in a number of European countries. We present a simple model explaining why such a reform can be opposed even when it is profitable to a majority of citizens. Then, we try to explain the existence of wide differences in the average length of retirement across countries and over time. [less ▲]
