We present an analytically tractable two-country New Open Economy Macroeconomics model of a currency union featuring an overlapping gen- erations structure of the Blanchard (1985)-Yaari (1965) type. It enables us to study the transmission and spillover effects of a wider range of fiscal shocks...

In this paper, we describe a new multi-country open economy SDGE model named SIGMA that we have developed as a quantitative tool for policy analysis. We compare SIGMA's implications to those of an estimated large-scale econometric policy model (the FRB/Global model) for an array of shocks that...

In this paper, we use an open economy DGE model (SIGMA) to assess the quantitative effects of fiscal shocks on the trade balance in the United States. We examine the effects of two alternative fiscal shocks: a rise in government consumption, and a reduction in the labor income tax rate. Our...

In this paper, I review the literature on the formulation and estimation of dynamic stochastic general equilibrium (DSGE) models with a special emphasis on Bayesian methods. First, I discuss the evolution of DSGE models over the last couple of decades. Second, I explain why the profession has...

This paper presents a flexible-price small open economy model with a peso problem in productivity states. Agents rationally adjust their beliefs about future productivity growth after the arrival of news. A downward revision of expectations triggers a Sudden Stop, together with large declines in...

The paper reviews exchange rate options for Mercosur countries. We start from the observation that most of the countries in the region have a longstanding tendency to adopt fixed exchange rates, and ask how such a system could best be designed. The Argentine crisis has demonstrated that...
