This paper constructs a small open two-sector overlapping-generations model with the subsistence level of consumption of agricultural goods and explains the following key stylized facts in the process of economic development: increases followed by declines in fertility rate, increases in human...

This paper examines how demographics affect economic growth in an OLG model with unfunded social security. We derive two interesting results. First, the relationship between population growth and per capita output growth is hump shaped. Second, the relationship between life expectancy and per...

Empirical studies show that the fertility rate (mortality rate) exhibits an inverted u-shaped dynamic in some countries, while it decreases monotonically in other countries. This paper formulates the concept of public health infrastructure and constructs a growth model that replicates various...

This paper constructs a simple rural-urban migration model that explicitly incorporates the interactions between the individual's migration decision, the risk of incurring an infectious disease and unemployment. We show that providing a subsidy for health investment in urban regions in the form...

This paper constructs a simple, overlapping generations version of an R&D-based growth model à la Diamond (1965) and Jones (1995), and examines how an increase in old-age survival probability impacts purposeful R&D investment and long-run growth by affecting fertility and education decisions....

This paper constructs a small open two-sector overlapping-generations model with the subsistence level of consumption of agricultural goods and explains the following key stylized facts in the process of economic development: increases followed by declines in fertility rate, increases in human...

This paper examines how pay-as-you-go (PAYG) pension reform from a defined-benefit scheme to a defined-contribution scheme affects economic growth in an overlapping generations model with endogenous growth. We show that in economies in which the old-age dependency ratio is relatively high and...
