Emerging market crises are characterized by large swings in both macroeconomic fundamentals and asset prices. The economic significance of observed movements in macroeconomic variables is obscured by the brief and extreme nature of crises. In this paper we propose to study the macroeconomic...

The first generation models of currency crises have often been criticized because they predict that, in the absence of very large triggering shocks, currency attacks should be predictable and lead to small devaluations. This paper shows that these features of first generation models are not...

We lay out a small open economy version of the Calvo sticky price model, and show how the equilibrium dynamics can be reduced to simple representation in domestic inflation and the output gap. We use the resulting framework to analyze the macroeconomic implications of three alternative...

We lay out a tractable model for fiscal and monetary policy analysis in a currency union, and study its implications for the optimal design of such policies. Monetary policy is conducted by a common central bank, which sets the interest rate for the union as a whole. Fiscal policy is implemented...

We construct a utility-based model of fluctuations, with nominal rigidities and unemployment, and draw its implications for the unemployment-inflation trade- off and for the conduct of monetary policy. We proceed in two steps. We first leave nominal rigidities aside. We show that, under a...

We develop and estimate a structural model of inflation that allows for a fraction of firms that use a backward looking rule to set prices. The model nests the purely forward looking New Keynesian Phillips curve as a particular case. We use measures of marginal costs as the relevant determinant...
