Working Paper
The Heterogeneous Effects of Government Spending : It’s All About Taxes
This paper investigates how government spending multipliers depend on the distribution of taxes across households. We exploit historical variations in the financing of spending in the U.S. since 1913 to show that multipliers are positive only when financed with more progressive taxes, and zero otherwise. We rationalize this finding within a heterogeneous-household model with indivisible labor supply. The model results in a lower labor responsiveness to tax changes for higher-income earners. In turn, spending financed with more progressive taxes induces a smaller crowding-out, and thus larger multipliers. Finally, we provide evidence in support of the model?s cross-sectional implications.

Working Paper
Foreign Effects of Higher U.S. Interest Rates
This paper analyzes the spillovers of higher U.S. interest rates on economic activity in a large panel of 50 advanced and emerging economies. We allow the response of GDP in each country to vary according to its exchange rate regime, trade openness, and a vulnerability index that includes current account, foreign reserves, inflation, and external debt. We document large heterogeneity in the response of advanced and emerging economies to U.S. interest rate surprises. In response to a U.S. monetary tightening, GDP in foreign economies drops about as much as it does in the United States, with a larger decline in emerging economies than in advanced economies. In advanced economies, trade openness with the United States and the exchange rate regime account for a large portion of the contraction in activity. In emerging economies, the responses do not depend on the exchange rate regime or trade openness, but are larger when vulnerability is high.

Working Paper
Sovereign Default: The Role of Expectations
We study a variation of the standard model of sovereign default, as in Aguiar and Gopinath (2006) or Arellano (2008), and show that this variation is consistent with multiple interest rate equilibria. Some of those equilibria correspond to the ones identified by Calvo (1988), where default is likely because rates are high, and rates are high because default is likely. The model is used to simulate equilibrium movements in sovereign bond spreads that resemble sovereign debt crises. It is also used to discuss lending policies similar to the ones announced by the European Central Bank in 2012.

Working Paper
Self-Fulfilling Debt Crises with Long Stagnations
We explore quantitatively the possibility of multiple equilibria in a model of sovereign debt crises. The source of multiplicity is the one identified by Calvo (1988). This type of multiplicity has been at the heart of the policy debate through the recent European sovereign debt crisis. Key for multiplicity in the model is a stochastic process for output featuring long periods of either high or low growth. We calibrate the output process in the model using data for the southern European countries that were exposed to the debt crisis. We find that expectations-driven sovereign debt crises are empirically plausible, but only in periods of stagnation. Multiplicity is state dependent: in periods of stagnation and for intermediate levels of debt, interest rates may be high for reasons unrelated to fundamentals.
