This paper analyzes the optimal time to abandon a fixed exchange rate regime in response to a fiscal shock that renders the peg unsustainable. We consider three variants of an optimization-based first-generation speculative attack model. In the first variant there are exogenous costs of...

This paper uses a unified analytical framework to assess, both qualitatively and quantitatively, the relevance of the different hypotheses that have been proposed to explain the real effects of exchange rate-based stabilizations. The four major hypotheses analyzed are: (i) the supply-side...

The influential Krugman-Flood-Garber (KFG) model of balance of payment crises assumes that a fixed exchange rate is abandoned if and only if international reserves reach a critical threshold value. From a positive standpoint, the KFG rule is at odds with many episodes in which the central bank...

Balanced growth models are commonly used in macroeconomics because they are consistent with the well-known Kaldor facts regarding economic growth. These models, however, are inconsistent with one of the most striking regularities of the growth process—the massive reallocation of labor from...

There is a well-known set of empirical regularities that describe the experience of countries that peg their exchange rate as part of a macroeconomic adjustment program. Following the peg economies tend to experience an increase in GDP, a large expansion of production in the non-tradable sector,...

The main purpose of this paper is to provide a simple analytical framework that can guide the development of indicators of fiscal policy sustainability in economies which operate in a highly volatile macroeconomic environment.
