On the optimal design of transfers and income-tax progressivity
We study the optimal design of means-tested transfers and progressive income taxes. In a simple analytical model, we demonstrate an optimally negative relation between transfers and income-tax progressivity due to efficiency and redistribution concerns. In a rich dynamic model, we quantify the optimal plan with flexible tax-and-transfer functions. Transfers should be larger than currently in the U.S. and financed with moderate income-tax progressivity. Transfers are key to implement higher progressivity in average than in marginal tax-and-transfer rates, achieving redistribution while ...

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 ...

Sectoral Shocks, Reallocation, and Labor Market Policies
Unemployment insurance and wage subsidies are key tools to support labor markets in recessions. We develop a multi-sector search and matching model with on-the-job human capital accumulation to study labor market policy responses to sector-specific shocks. Our calibration accounts for structural differences in labor markets between the United States and the euro area, including a lower job-finding rate in the latter. We use the model to evaluate unemployment insurance and wage subsidy policies in recessions of different duration. We find that, after a temporary sector-specific shock, ...

Self-Fulfilling Debt Crises with Long Stagnations
We assess the quantitative relevance of expectations-driven sovereign debt crises, focusing on the southern European crisis of the early 2010s and the Argentine default of 2001. The source of multiplicity is the one in Calvo (1988). Crucial for multiplicity is an output process characterized by long periods of either high growth or stagnation, which we estimate using data for these countries. We find that expectations-driven debt crises are quantitatively relevant but state dependent, as they occur only during periods of stagnation. Expectations, and how they respond to policy, are the major ...

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.

International Trade and Gender Gaps in College Enrollment
A large body of work suggests that trade affects workers unevenly. By shifting economic activity across occupations, industries, or regions, freer trade can generate gains for some workers and losses for others.

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 ...
