Education Subsidies and Endogenous Growth : Implications of Demographic Shocks

In this paper we develop a three-period overlapping generations model in which individual decisions about education are the engine of growth. In this setting, it is first shown that an education subsidy combined with a hunJrsum redistribution from adults to retirees makes it possible to reach the optimum in a market context. Then we examine how these transfers should be adjusted in the presence of unexpected natality shocks. Especially, in the case of a " baby boom-baby bust" shock, the sharing of the shock burden requires increased transfers to retirees when the share of elderlies peaks.
