Abstract. Evaluating the allocative effects of recessions is challenging due to the dynamic and jointly evolving distributions of workers and firms. Workers constantly gain or lose human capital, while the landscape of firms shifts with cyclical vacancy posting, entry and exit. We build a search model with aggregate risk and worker-firm heterogeneity, in which human capital accumulation depends on the sorting of workers to firms. The framework allows us to account for how workers' skills and firms' distributions jointly vary and impact business cycles. We estimate the model on administrative data and show that persistent negative effects on the productivity of worker-firm matches dominate cleansing effects, with distortions in sorting and human capital accumulation accounting for approximately 60% of cumulative output losses. Our model offers a rationale for the increased length of recessions and their heterogeneous welfare effects across age, income, and human capital distributions.

Abstract. Student debt decreases post-bachelor school enrollment and earnings growth but does not delay first-time home ownership. We introduce a life-cycle human capital model with heterogeneous wealth and financial frictions and show that high debt balances distort career choices because returns to further education depend on current income. Student debt impacts home ownership in two ways. First, it deters ownership via the traditional wealth channel. Second, it increases ownership by discouraging further education in favor of early labor market entry. Finally, we show that the impact of student borrowing is partly due to the design of US student loans.

On the Solution of High-Dimensional Macro Models with Distributional Channels
R & R at Computational Economics, also available at SSRN
Presentations: Computation in Economics and Finance Conference (Milan), Sparse Grids and Applications Conference (Munich), UZH Finance, SFI Research Days

Abstract. I propose a global solution method for the computation of infinite-horizon, heterogeneous agent macroeconomic models with aggregate uncertainty. Details of the algorithm are illustrated by presenting its application to a an example model of firm dynamics. In the model, aggregate dynamics depends explicitly on firm entry and exit, and individual choices are often constrained by a form of market incompleteness. Existing computational strategies are either unfeasible or provide inaccurate solutions to this class of models. Moreover, global solutions are computationally expensive because the minimal representation of the aggregate state space - and thus the aggregate law of motion - faces the curse of dimensionality. The proposed strategy combines adaptive sparse grids with a cross-sectional density approximation, and introduces a framework for solving the more general class of dynamic models with firm or household heterogeneity accurately.

Parental Health, Aging, and the Labor Supply of Young Workers

Abstract. To what extent are young workers affected by health shocks that happen to their parents? This paper studies the short and long-term spillover effects of parents' adverse health events on their adult children. We use the unique structure of the Panel Survey on Income Dynamics (PSID) to build family networks and construct a measure of sudden health changes. Exploiting news on parents' health status, we provide evidence of the existence of family insurance in the form of time and monetary transfers, and of the importance of family ties in shaping labor market outcomes. Following the deterioration of parents' health, time spent helping them goes up, while income and hours worked by children significantly decline.
