In this paper, we analyse the effects of demographic change on a PAYG pension system, financed with a defined contribution scheme. In particular we examine the relationship between retirement, fertility and pensions in a three-period overlapping generations model. We focus on both the case of...

This paper studies retirement and child support policies in a small, open, overlapping-generations economy with PAYG social security and endogenous retirement and fertility decisions. It demonstrates that neither fertility nor retirement choices necessarily coincide with socially optimal...

Since the 1990s, Lithuania lost almost a quarter of its population, and some regions within the country lost more than 50% of their residents. Such a sharp population decline poses major challenges to politicians, policy makers and planners. This study aims to get more insight into the recent...

We assess Africa's prospects for enjoying a demographic dividend. While fertility rates and dependency ratios in Africa remain high, they have started to decline. According to UN projections, they will fall further in the coming decades such that by the mid-21st century the ratio of the...

France experienced the demographic transition before richer and more educated countries. This paper offers a novel explanation for this puzzle that emphasizes the diffusion of culture and information through internal migration. It tests how migration affected fertility by building a decennial...

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...

Dynamic adjustments could be a useful strategy for mitigating the costs of acute environmental shocks when timing is not a strictly binding constraint. To investigate whether such adjustments could apply to fertility, we estimate the effects of temperature shocks on birth rates in the United...

This paper uses a model with overlapping generations to demonstrate that human capital accumulation can potentially attenuate factor price movements in response to birth rate shocks. Specifically, we show that if education spending per child is inversely related to the size of the generation,...

This paper explores gendered patterns of time use as an explanatory factor behind fertility trends in the developed world. We review the theoretical foundations for this link, and assess the existing evidence suggesting that a more equal division of labor within the home leads to more children,...

This paper reviews Gary Becker's contributions to the economic analysis of fertility, from his 1960 paper introducing the quantity-quality tradeoff to later work linking the economics of fertility to the theory of economic growth.
