This paper revisits the literature on overlapping generations models in the demographic context of a continuous age distribution and a general age schedule of mortality. We show that most of the static results known for the 3 or N age-group models can be extended to the continuous model. Some...

The US population will age rapidly for several decades and then more slowly, with less aging than most rich nations. Health of the elderly has greatly improved, but disability stagnated after 2000. Retirement age reversed its decline in the mid-1990s and health status leaves ample room for...

Abstract At each age an organism produces energy by foraging and allocates this energy among reproduction, survival, growth, and intergenerational transfers. We characterize the optimal set of allocation decisions that maximizes fitness. Time preference (the discount rate) is derived from the...

This chapter discusses the possibility of long-run economic-demographic equilibrium, examines empirical evidence bearing on the key relationships hypothesized to establish equilibriumthe preventive check, the positive check, and a depressing effect of population growth on real wages reflecting...
