European monetary union and asymmetric shocks in a new Keynesian model

This paper attempts to quantify the costs imposed by asymmetricshocks under European Monetary Union compared to free floating.A simple two-country model is examined where policy is set inan optimal, time consistent manner. Nominal and real rigiditiesare present in both economies, but prices are set in a forwardlooking manner and expectations are rational. Results suggestthat the costs of asymmetric shocks under EMU may be significantlyhigher than under free floating, particularly if fiscal policyis not used for demand management.
