Monopolistic Competition, Relative Prices, and Output Adjustment in the Open Economy

Working Paper: NBER ID: w1787

Authors: Joshua Aizenman

Abstract: The purpose of this paper is to explain price and output dynamics in an open economy characterized by a monopolistic competitive market structure in which pricing decisions incur costs. That lead producers to pre-set the price path for several periods. The paper derives an optimal pricing rule, including the optimal pre-setting horizon. It does so for a rational expectation equilibrium, characterized by staggered, unsynchronized price setting, for which the degree of staggering is endogenously determined. The discussion focuses on the critical role of the degree of domestic-foreign goods substitutability in explaining price and output effects of monetary and real shocks.
