Abstract

We consider fiscal sustainability by using an overlapping generations model with human capital accumulation (private and public education) and public debt. Based on this model, we explicitly show (i) the parameter region in which the economy cannot be fiscally sustainable for any initial endowment, and (ii) the threshold of initial endowment over (under) which the economy diverges (converges) to the steady state. Importantly, the threshold is neutral to the level of initial human capital. Further, we show the existence and uniqueness of the growth-maximizing level of each policy variable (i.e., the tax rate and public education/production ratio).
