Post-retirement, the model in the main text (published in the Review of Economic Dynamics) reduces to the Merton (1969) problem, which has of course an exact solution. Pre-retirement, however, the agent holds an American option, namely, retire now or keep working. Problems involving American...

A model with leisure production and endogenous retirement is used to explain the declining labor-force participation rates of elderly males. Using the Health and Retirement Study, the model is calibrated to cross-sectional data on the labor-force participation rates of elderly US males by age...

This paper presents a method to estimate the effects of a counterfactual policy intervention in the context of dynamic structural models where all the structural functions (i.e., preferences, technology, transition probabilities, and the distribution of unobservable variables) are...

This paper estimates a life cycle model of labor supply, retirement and savings behavior in which future health status and wages are uncertain. Individuals face a fixed cost of work and cannot borrow against future labor, pension, or Social Security income. The method of simulated moments is...

This paper studies a quantitative dynamic general equilibrium life-cycle model where parents and their children are linked by bequests, both voluntary and accidental, and by the transmission of earnings ability. This model is able to match very well the empirical observation that households with...

In this paper we analyze tax and transfer choices in an OLG economy with capital accumulation and endogenous growth coming from public investment, such as education. We solve for a Markov perfect equilibrium when electoral competition targets the votes of young and old households. We find that...

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...

We examine the possibility of a Pareto-improving pay-as-you-go social security system, using an ex-ante welfare criterion. Our objective is to identify the conditions under which a suitably designed pay-as-you-go social security system is welfare improving, when markets are complete and...

The paper derives conditions for ex ante efficient intergenerational risk sharing in overlapping generations models. I show how the efficiency of a fiscal policy can be evaluated without distributional judgments, I derive efficiency conditions, and then examine specific models. For models with...

In all major industrialized countries the population is aging over time, reducing the fraction of the population in working age. Consequently labor is expected to be scarce, relative to capital, with an ensuing decline in real returns on capital and increases in real wages. This paper employs a...
