Devaluation,long-term contracts and rational expectations

This paper considers the effects of devaluation and expected devaluation on output, prices and foreign exchange reserves in a small open economy with overlapping two period wage contracts and rational expectations. A devaluation has an expansionary effect on output provided it is unanticipated by at least some contracts when it occurs. Expected devaluations, however, have no effect on prices until they take place. If a devaluation is expected, but fails to take place, output is reduced. Reserves increase in response to all devaluations; but the expectation of a devaluation causes a loss of reserves prior to its expected date.
