This paper develops a quantitative Markovian overlapping generations model with altruistic individuals and incomplete financial markets in order to analyze the long-run distributional implications of two hypothetical public social security policy changes, made in response to impending future...

Comment assurer la pérennité de notre système de retraite par l'allongement de la vie active lorsque moins d'un salarié sur deux parvient aujourd'hui à prendre sa retraite sans passer préalablement par l'inactivité ou le chômage ? Nous montrons dans cet article qu'une partie du problème...

It is argued that the tax on continued activity should be removed by implementing actuariallyfair schemes. However, these schemes cannot fund the expected Social Security deficit. This paper proposes to give individuals a fraction of the actuarially-fair incentives in the case of postponed...

Gali et al. (2007) have recently shown in a quantitative way that inefficient fluctuations in the allocation of resources do not generate sizable welfare costs. In this note, we show that their evaluation underestimates the welfare costs of inefficient fluctuations and propose a biased estimate...

We investigate the welfare cost of business cycles implied by matching frictions. First, using the reduced-form of the matching model, we show that job finding rate fluctuations generate intrinsically a non-linear effect on unemployment: positive shocks reduce unemployment less than negative...

This paper presents a theoretical foundation and empirical evidence in favor of the view that the retirement age decision impacts on the employment of older workers before this age. Countries with a retirement age at 60 are indeed characterized by lower employment rates for workers aged 55-59....

En France, une année supplémentaire au-delà du taux plein dans le régime général ne donne droit à aucune augmentation de pension. Cette taxe sur le prolongement d'activité distort les choix des agents en faveur d'un âge de départ en retraite inférieur à celui qui prévaudrait dans un...

Phelps (1994) presented the case for a low-wage subsidy policy. Since the mid-1990s, France has experimented with this strategy. This paper evaluates the e®ect of this policy on employment and also on output and welfare. We construct an equilibrium search model incorporating wage posting and...

Sur la base de l'enquête emploi, nous montrons que la probabilité d'être en emploi dépend positivement de la distance à la retraite, en plus des variables d'intérêt traditionnelles. Cet exercice repose sur une stratégie permettant d'identifier la dimension exogène de la distance à la...
