The world's population is aging. Virtually no nation is immune to this demographic trend and the challenges it brings for future generations. Relative growth of the elderly population is fueling debate about reform of social security programs in the United States and other developed nations. In...

This paper describes how stochastic population forecasts are used to inform and analyze policies related to government spending on the elderly, mainly in the context of the industrialized nations. The paper first presents methods for making probabilistic forecasts of demographic rates,...

The aging of the global population is in the headlines following a report that China's population fell as deaths surpassed births. Pundits worry that a declining Chinese workforce means trouble for other economies that have come to rely on China's exports. France is pushing through an increase...

We examine the dynamic interaction of the population age structure, economic dependency, and fertility, paying particular attention to the role of intergenerational transfers. In the short run, a reduction in fertility produces a “demographic dividend” that allows for higher consumption. In...

Population aging is primarily the result of past declines in fertility, which produced a decadeslong period in which the ratio of dependents to working age adults was reduced. Rising old-age dependency in many countries represents the inevitable passing of this “demographic dividend.”...

The demographic transition that swept the world in the course of the last century has been identified as one of the prime forces in the transition from stagnation to growth. The unprecedented increase in population growth during the early stages of industrialization was ultimately reversed and...

We assess quantitatively the effect of exogenous reductions in fertility on output per capita. Our simulation model allows for effects that run through schooling, the size and age structure of the population, capital accumulation, parental time input into child-rearing, and crowding of fixed...

This study investigates the general equilibrium effects of a fertility shock under different intergenerational transfer schemes. The effects on lifetime income and utility for different generations, as well as the effects on factor prices, are analyzed in a three-period overlapping generations...

There is a rich literature analyzing the problems that will arise as the share of elderly and retired in the population increases in the near future. However, the locational decisions among the elderly as well as their implications in terms of taxes/transfers and of allocation of...

We analyze the effect of the projected demographic transition on the political support for social security, and equilibrium outcomes. Embedding a probabilistic-voting setup of electoral competition in the Diamond (1965) OLG model, we find that intergenerational transfers arise in the absence of...
