The Micro Anatomy of Macro Consumption Adjustments (NBER Working Paper)
with Pablo Ottonello and Diego Perez
Forthcoming, American Economic Review
We study crises characterized by large adjustments of aggregate consumption through their microlevel patterns. We document the cross-sectional patterns of consumption adjustment across the income distribution and  find large adjustments for top-income households, who exhibit consumption-income elasticities similar to or larger than the average. We construct a heterogeneous-agent open economy model of consumption under income fluctuations and show that the data patterns are largely consistent with theories that attribute the dynamics of aggregate consumption to changes in aggregate permanent income. We also discuss our findings' implications for theories based on the tightening of households' borrowing constraints and analyze policy implications.

Firms' Rollover Risk and Macroeconomic Dynamics (slides | thread)
Job Market Paper
2022 National Prize in Economics (Premio Raul Trajtenberg) Uruguay
This paper analyzes the macroeconomic implications of firms’ rollover risk. I develop a heterogeneous-firms macroeconomic model with rollover crises emerging from coordination failures among creditors. Rollover crises are events in which a firm defaults because creditors fail to roll over its debt, but would have repaid otherwise. I assess the quantitative relevance of rollover crises by employing a model-based identification strategy which argues that their incidence is informed by the observed distribution of firms’ bankruptcy outcomes, and find that roughly half of bankruptcy events are due to rollover crises. I validate the model using individual firms' observed investment dynamics during the last recessions and then use the model to assess the aggregate implications of rollover risk for the U.S. economy. I find that rollover risk can significantly amplify the impact of recessions. Lastly, I show that imperfectly-targeted credit policies can mitigate rollover crises but can exacerbate firms' debt overhang in the future.

Financial Frictions and the Market for Firms
with Federico Kochen
We study and quantify the aggregate implications of the trade of firms in the presence of financial frictions. In the U.S., one out of four entrepreneurs purchased their business. However, this number has decreased in the last three decades. In the cross-section, younger, smaller, and high return to capital firms have the highest trading rates. To explain these findings, we propose a model of entrepreneurship with a frictional market for firms in which gains from trade can arise from credit constraints and incomplete financial markets. Our results suggest that the better allocation of capital due to the trade of firms is significant, accounting for 9.1% of entrepreneurial output and 2.2% of TFP.

The Business Cycle Volatility Puzzle: Emerging vs Developed Economies

Working From Home and Contact-Intensive Jobs in Uruguay (spanish | slides | post | data + codes)
RISEP paper (Social Sciences Research Network to Confront Sequels of the Pandemic - Uruguay)
supplementary material: risky jobs in Uruguay (spanish)
coverage: CEPAL, UNDP, UNDP blog, ILO, En la Mira (TV), El Observador (newspaper), El Pais Uruguay (newspaper), Puntos de Vista (radio)
In this article, I estimate how many workers have jobs that can be performed at home (WFH) and jobs with close physical contact to other people (CI) in Uruguay. To identify the jobs that are WFH and CI, I adopt the methodology of Dingel & Neiman (2020) and Mongey, Pilossoph & Weinberg (2020) used for US. My baseline estimates show that around 78% of the workers in the private sector can’t WFH and 22% have CI jobs. Next, I find large heterogeneity in WFH and CI propensities across the income distribution, geographical locations, age groups, education levels, and production sectors. In addition, I study the relation of WFH and CI measures with household access to social insurance, hand-to-mouth propensity, intrahousehold insurance and job-automation risk. Lastly, I show that my baseline estimates of WFH are consistent with ex-post survey estimations during the Covid-19 pandemic lockdown in Uruguay.
