Money and the Open Economy Business Cycle: A Flexible Price Model

This paper develops an open-economy model of the business cycle. The nominal prices in the model are flexible and monetary nonneutrality is developed using information confusion about the sources of disturbances to demand coupled with differential persistence of demand shocks. Firms use inventories to smooth their production, and consumers follow a stochastic permanent income expenditure function. The major implication of the model is that unperceived monetary disturbances improve the terms of trade and increase real output in contrast to sticky price models in which the terms of trade deteriorates. This implication of the model is examined empirically.
