Cash-in-advance constraints in the diamond overlapping generations model: neutrality and optimality of monetary policies.

This paper is a study of money in overlapping generations models with cash-in-advance constraints. We first offer a brief review of different features of the cash-in-advance constraint. Then we propose a general formulation and study the neutrality of money. We show that both neutrality and equilibrium dynamics depend on the form of the cashin-advance constraint. We then show that optimal intergenerational resources sharing can be implemented through monetary transfers. Finally, we find that the Chicago Rule is implied by optimal monetary policy.
