Abstract

A two-country dynamic general-equilibrium model with imperfect competition and price stickiness is considered. This work shows the conditions under which price stability can implement the flexible-price allocation as a Nash equilibrium. This is possible if and only if both countries maintain a certain positive degree of monopolistic competition. In such equilibrium, the monetary policymakers have no incentive to surprise price setters ex post.
