The public pension systems of the G7 countries were established in an era when the number of contributors far outweighed the number of beneficiaries. Now, for each beneficiary there are fewer contributors, and this trend is projected to accelerate. To evaluate the prospects for these economies...

In this paper, we examine the effects of introducing actuarially fair annuity markets into an overlapping generations model of endogenous growth. We find the complete annuitization of agents' wealth is not, in general, dynamically optimal; that the degree of annuitization that is dynamically...

In the last few decades in the United States birth rates have declined and longevity has risen while productivity growth has slowed. Given such changes, the increasing burden of funding programs for the elderly is likely to shift resources away from the young and toward the elderly. This paper...

The Social Security systems of the G7 countries were established in an era when populations were young and the number of contributors far outweighed the number of beneficiaries. Now, for each beneficiary there are fewer contributors, and this downward trend is projected to accelerate. To...

This paper examines international capital flows in the context of a simple Diamond-Dybvig model in which there are neither moral hazard nor adverse selection problems, thus isolating exchange rate risk as the propagator of capital flows. The model shows that adverse changes in exchange rate...

This paper develops a model to examine the effects of introducing a fully-funded government sponsored pension plan into an overlapping generations model with an extant pay-as-you-go social security system. We examine whether individual and social welfare can be improved by phasing out the...

We develop a model of an overlapping generations economy characterized by private pensions where risk averse agents face both longevity and investment risks. The government mitigates the effects of longevity risk by mandating that individuals purchase annuities. Investment risk arises since the...
