Aging, Growth and the Allocation of Public Expenditures on Health and Education

In this paper, I develop an overlapping generations endogenous growth model in which both public education and health are sources of growth by affecting the accumulation rate of the human capital stock and the savings rate over life expectancy. I first find that dynamic complementarities of public expenditures lead to minimum threshold levels of public education and health expenditures that ensure sustainable growth. I then show how governments can use the allocation of public expenditures as an alternative policy instrument to maximize growth without increasing the tax rate or the retirement age, as usually happens in aging economies.
