We study the labor supply dynamics of elderly couples by means of a structural collective model.The model allows for general externalities with respect to spouses leisure.Preferences and the intrahousehold bargaining process are identified by using panel data with couples and individuals who...

In a stochastic economy with overlapping generations, fiscal policy affects the allocation of aggregate risks. The paper shows how to compute the welfare effects of marginal policy changes that shift risk across cohorts, in general and for an application to social security equity investments. I...

This paper studies the optimal trade-off between commitment and flexibility in an intertemporal consumption/savings choice model. Individuals expect to receive relevant information regarding their own situation and tastes - generating a value for flexibility - but also expect to suffer from...

How far is the US social insurance system from an efficient system? We answer this question within a model where agents receive idiosyncratic, labor-productivity shocks that are privately observed. When social security and income taxation comprise the social insurance system, the maximum...

This paper analyses the effects of reducing unfunded social security in a closed economy that consists of a service sector and a commodity sector.It is shown that if old agents mainly demand labour intensive services, a modest decrease of the pay-as-you-go pension scheme still raises long-run...

This paper analyses the effects of reducing unfunded social security and population ageing on economic growth and welfare, both for a small open economy and for a closed economy.The economy consists of a service sector and a commodity sector.Productivity growth only occurs in the latter sector...

In this paper decision making on public pensions is modeled within the framework of the well-known two-overlapping-generations general-equilibrium model with rational expectations. The model is used to analyze the effects of aging on the evolution of public pension schemes. Analytical results...
