The present paper addresses two questions. First, how does exchange rate overshooting affect hysteresis in trade and competitiveness? Second, how does 'short-termism' alter the magnitude of such hysteresis effects? The paper models the dynamic processes of hysteresis in trade and competitiveness in terms of the presence of discrete, asymmetric lump-sum costs of entry, in response to unanticipated foreign policy shocks. The paper produces some important new insights into the role of short ran adjustment processes in understanding persistence effects in key macroeconomic indicators.
