The objective of this paper is to analyze the effects of alternative monetary rules on realexchange rate persistence. Using a two-country stochastic dynamic general equilibrium withnominal price stickiness and local currency pricing, we will show how the persistence ofpurchasing power parity...

This paper analyses predictions of a simple model of currency crises in which the peg will beabandoned when the currency overvaluation hits a certain threshold, unknown to the agents. Due tolearning about the threshold, some features usually observed in the data and identified with modelswith...

In a country with high probability of default, higher interest rates may render the currency lessattractive if sovereign default is costly. This paper develops that intuition in a simple model andestimates the effect of changes in interest rates on the exchange rate in Brazil using data from...

This paper shows that properly designed interest rate rules can be consistent withmaintaining exchange rate stability. It sheds light on the relation between interest rate rules,exchange rate regimes, and determinacy of the rational expectation equilibrium in a modernmacroeconomic framework.[...]

We propose a theory of exchange rate determination under interestrate rules in a two-country model. We first show that simpleinterest rate feedback rules can determine a unique and stableequilibrium without any explicit reaction to the nominal exchangerate.We characterize how the behavior of the...

This paper addresses the consumption–real exchange rate anomaly.International real business cycle models based on complete financialmarkets predict a unitary correlation between the realexchange rate and the ratio of home to foreign consumptionwhen subjected to supply-side shocks. In the data,...
