Under the assumption of no arbitrage exchange rate target zone credibility is tested by whether domestic interest rates fall within “rate-of-return bands” between the maximum and minimum home-currency rate of return on a foreign investment absent a devaluation. Under the assumption of uncovered interest rate parity credibility is tested by whether expected future exchange rates fall within the exchange rate band. These tests are applied on data about the Swedish target zone during January 1987-August 1990.

Abstract: addition, the expected future exchange rates are used to give an estimate of the

Trade liberalization in developing countries is frequently opposed on the grounds that, because it is likely to cause a deterioration in the external balance, it may not be a viable policy option for countries facing foreign exchange constraints. Recent literature suggests, however, an ambiguous relationship between tariff changes and the current account.
