On the Indeterminacy of Equilibrium Exchange Rates

Abstract

In this paper we consider a particular international economic policy regime: the laissez-faire regime, the distinguishing features of which are unrestricted portfolio choice and floating exchange rates. And as we show, that regime, although favored by many economists, is not economically feasible. It does not have a determinate equilibrium. That is an implication of an over-lapping-generations model. But as we argue in the paper, that is no reason for doubting the indeterminacy of the laissez-faire regime equilibrium.
