Sticky Prices and Indeterminacy

Abstract

The aim of the present paper is to analyze the link between price rigidity and indeterminacy. This is done within a cash-in-advance economy from which we know that it exhibits indeterminacy at high degrees of relative risk aversion. I find that price stickiness reduces the scope of these sunspot equilibria: sluggish price adjustment requires degrees of relative risk aversion compatible with indeterminacy that prove too high to square with data.Cash-in-advance economies; Calvo-pricing; sunspot equilibria.
