This paper proposes an intertemporal and consistent framework in order to measure the incentives for returning to employment. A job seeker accepts a job which maximizes the sum of his discounted expected incomes, taking into account earnings associated with every job, worker?s mobility between...

We analyse back to work incentives taking into account intertemporal gains and worker mobility between jobs. Theoretically, we show that these incentives vary depending on the difference between replacement benefits and bad jobs wages. They are also sensible to the accessibility and stability of...

« Social freedom » and the respect of corresponding rights, as well as Pareto efficiency (a priori required by democracy), imply that taxes and subsidies (re)distributing income are based on given « natural resources », the main of which ?'by very far?' consists of individuals?' productive...

Pension systems imply an intra-generational redistribution of resources. In this way, it changes the distribution of wealth in the population, which can affect the behavior of agents, notably for their educational choices. In this paper, we show that if a pension system is progressive, then an...

We examine the determination of the optimal (from the point of view of social welfare) retirement age. We analyze the relationship between the choice of the retirement age and the choice of the nature of the pension system (relative shares of the pay-as-you-go and of the capitalized system). We...

We study the transition from an unfunded to a funded pension system in an endogenous growth overlapping generations model (with positive externality of aggregate capital stock on individual producers). We suppose that workers have different skill levels. We distinguish cases where the initial...

The first pillars of pension plans in the various European countries widely differ in their contribution rates and intra-generational redistribution. What would be the impact of these differences if EU citizens had a free access to the various systems? This paper aims to highlight some basic...

We modify the two period OLG model in order to distinguish the effects of individual ageing from changes in birth rate. We characterize optimal pension and retirement age policies in a dynamic framework. We consider a mixed pension scheme, fully funded but offering agents an actuarially fair...

It is often argued that implicit taxation on continued activity of elderly workers is responsible for the widely observed trend towards early retirement. In a first best world, it is certainly possible to eliminate this taxation and have a social security scheme that is redistributive and...

We extend McCall?s [1970] job search model by explicitly integrating life-cycle features and retirement decisions. Using simulations, we show that the effective tax on continued activity caused by the French social security system in conjunction with the generosity of unemploymentn benefits for...
