We analyze the profitability of FX swaps used by the central bank of Brazil to shed light on the rationale for FX intervention. We find that swaps are profitable in expectation, suggesting that FX intervention is used to stabilize the exchange rate in the face of temporary excessive movements...

This paper examines the behavior of real interest rates in exchange-rate based stabilization programs. The analysis is based on a model with imperfect capital mobility and optimizing agents. A permanent reduction in the devaluation rate is first shown to have an ambiguous effect on real interest...

We present a model of a “soft” exchange rate target zone and interpret it as a stylized description of the post-August 1993 ERM. Our central bank targets a moving average of the current and past exchange rates, rather than the exchange rate’s current level, thus allowing the rate to move...

De facto (unofficial) dollarization, defined as the holding by residents of assets and liabilities denominated in a foreign currency, is a policy concern in an increasing number of developing economies.

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...

This paper analyzes the implications of devaluation and a variety of structural disturbances in a dual exchange rate economy. A key feature of the model developed is its explicit recognition of both private (fraudulent) and officially-sanctioned cross transactions between the two exchange...

This paper assesses the role of trade patterns in shaping the volatility of the effective exchange rate under two alternative peg regimes: a hard peg to a single currency and a peg to a basket of currencies. I link the changes in the nominal effective exchange rate of a pegged currency to the...
