Optimal Fiscal Policy in Overlapping Generations Models
Session: C-5-7  Sunday 13 August 2000  by Garriga-Calvet, Carlos
This paper analyzes the optimal fiscal policy in overlapping generation economies with production where agents live I periods. The primal approach is used to characterize the optimal taxes in steady state and along the transition path to some steady state. The basic idea is to transform the government problem of choosing the optimal taxes, into a simple programming problem of choosing allocations subject to some constraints. The key findings is that if the set of taxes is complete and the utility is homothetic and separable, then capital taxes are zero along the transition path to the steady state after two periods. This result is an equivalent version of Chamley (1986) with overlapping generations. With additional assumptions in the discount factor and endowment of efficiency units, it can be shown that non-separable utility functions satisfy the zero capital taxes result in steady state, but not during the transition path. This is due to the fact that from the government point of view, under this assumptions, the overlapping generation economy is equivalent to an infinitely lived economy.
