[Abstract]: To understand the link between financial intermediation activities and the real economy, we build a general equilibrium model in which agency frictions in the financial sector affect the efficiency of capital reallocation across firms and generate aggregate economic fluctuations. We develop a recursive policy iteration approach to fully characterize the nonlinear equilibrium dynamics and the o_-steady-state crisis behavior. In our model, adverse shocks to agency frictions exacerbate capital misallocation and manifest themselves as variations in total factor productivity at the aggregate level. Our model endogenously generates countercyclical volatility in aggregate time-series and countercyclical dispersion of marginal product of capital and asset returns in the cross-section.
16. The effects of marriage-related taxes and Social Security benefits, with Margherita Borella and Mariacristina De Nardi, NBER working paper #23972
[Abstract]: In the U.S., both taxes and old age Social Security benefits depend on one's marital status and tend to discourage the labor supply of the secondary earner. We study the effects of eliminating these marriage-related provisions on the labor supply and savings of two different cohorts. To do so, we estimate a rich life-cycle model of couples and singles using the Method of Simulated Moments (MSM) on the 1945 and 1955 birth-year cohorts. Our model matches well the life cycle profiles of labor market participation, hours, and savings for married and single people and generates plausible elasticities of labor supply. We find that these marriage-related provisions reduce the participation of married women over their life cycle, the participation of married men after age 55, and the savings of couples. These effects are large for both the 1945 and 1955 cohorts, even though the latter had much higher labor market participation of married women to start with.

19. The changing opportunities and outcomes of non-college educated Americans, with Margherita Borella and Mariacristina De Nardi
[Abstract]: We show that white, non-college-educated Americans born in the 1960s face lower life expectancies and higher medical expenses compared to those born in the 1940s. In addition, men's wages for each unit of human capital declined much more than women's across these cohorts. We calibrate a life-cycle model of couples and singles to match the labor market and savings outcomes of the white, non-college-educated 1960s cohort and use it to evaluate the effects of these changes. The changes in wages depressed the labor supply of men and increased that of women, especially in married couples. The decrease in life expectancy reduced retirement savings but the increase in out-of-pocket medical expenses increased them by more. Single men experienced the largest welfare losses, requiring a one-time asset compensation corresponding to 12.5% of the present discounted value of their earnings. Single women experienced a 7.2% welfare loss. Couples had a welfare loss of 8%. Lower wages explain 47-58% of these losses, shorter life expectancies explain 25-34%, and higher medical expenses account for the rest.
