Using an optimizing model of a small open economy, this paper studies the macroeconomic effects of PPP rules whereby the government increases the devaluation rate when the real exchange rate defined as the price of tradables in terms of nontradables is below its long-run level and reduces the...

This paper shows that the risk of devaluation can be an important factor accounting for the stylized facts of exchange-rate-based stabilizations. This conclusion follows from studying the quantitative implications of a two-sector equilibrium business cycle model of a small open economy...

Recently a number of authors have criticized the role of devaluations in traditional stabilization programs. It has been argued that, contrary to the traditional view, devaluations are contractionary, and generate a decline in aggregate output. In spite of the renewed theoretical interest in the...

Recent macroeconomic models of developing countries have emphasized the possibility of contactionary devaluations, stressing that domestic aggregate demand is likely to be reduced by the devaluations while aggregate supply may respond only slowly to the change in relative prices brought about by...

The central hypothesis of this paper is that both the extent and speed of adjustment of the real exchange rate is affected by the way the central bank manages the nominal exchange rate. Specifically, a large discrete adjustment of the nominal exchange rate is more likely to result in fast...

Motivated by the long-standing debate on the pros and cons of competitive devaluation, we propose a new perspective on how monetary and exchange rate policies can contribute to a country's international competitiveness. We refocus the analysis on the implications of monetary stabilization for a...

This paper proposes a tractable and realistic nonlinear model of exchange rate dynamics, and argues that its predictions are consistent with available empirical evidence on exchange rate and interest differential behavior in real-life target zones. In our model, the exchange rate fluctuates...

A salient characteristic of sovereign defaults is that they are typically accompanied by large devaluations. This paper presents new evidence of this empirical regularity known as the Twin Ds and proposes a model that rationalizes it as an optimal policy outcome. The model combines limited...

This paper studies the behavior of inflation after nine large post-1990 contractionary devaluations. A salient feature of the data is that inflation is low relative to the rate of devaluation. We argue that distribution costs and substitution away from imports to lower quality local goods can...

What is the relationship between interest rates and the exchange rate? The empirical literature in this area has been inconclusive. We use an optimizing model of a small open economy to rationalize the mixed empirical findings. The model has three key margins. First, higher domestic interest...
