Unexpected longevity can bring economic hardship to the elderly and affect the young through intergenerational policies. This paper studies the dynamic effects of longevity on policies and fertility, distinguishing between those of expected and unexpected longevity gains. In an...

Paul Samuelson made a series of important contributions to population theory for humans and other species, evolutionary theory, and the theory of age structured life cycles in economic equilibrium and growth. The work is highly abstract but much of it was intended to illuminate issues of...

We assess the impact of continued low fertility in China, versus a rebound in fertility due to the relaxation of the one child policy, on demographic and macroeconomic outcomes in a dynamic general equilibrium framework. We use a rich model of human capital investment, public health insurance,...

In their recent paper, Boldrin and Montes (2005) analyze the "return on human capital investment" theory and show that if borrowing for education is not possible, then a combined public education and pension system that uses lump sum taxes and transfers can replicate the first-best decentralized...

The pay-as-you-go social security system, which suffers from dwindling labor force, can benefit from immigrants with birth rates that exceed the native-born birth rates in the host country. Thus, a social security system provides effectively an incentive to liberalize migration policy. The paper...

This paper analyzes Singapore’s multi-pronged approach to managing prolonged low fertility which has led to population aging, labor force shortages, increasing elderly dependency ratios, and feminization of the elderly population. This approach has emphasized high growth, and has given...

The role of inherited wealth in modern economies has increasingly become under scrutiny. This study presents one of the first attempts to shed light on how demographic aging could shape this role. We show that, in the absence of retirement annuities, or for a given level of annuitization, both...

How are notional defined contribution (NDC) pension schemes and fertility correlated? How is the return rate of NDC account determined? This study elucidates the dynamics of the correlations between NDC pension schemes and fertility by considering endogenous labor supply in an imperfect labor...

Blacks, Hispanics, and divorced women have historically experienced double-digit poverty rates in retirement, and divorce and other demographic trends will increase their representation in future retiree populations. For these reasons, we might expect an increase in the proportion of...
