Curriculum Vitae

Welcome to my website! I am an Assistant Professor in the Economics Department at Clemson University. I received my Ph.D. in Economics from the University of Rochester in 2024.

My research interests are in macroeconomics and labor economics. My work combines structural estimation with micro and administrative data to study life-cycle labor supply, consumption behavior, and business cycle dynamics.

Consumption's Response to Permanent Income: The Role of Consumption Commitments

(December 2025)

The permanent-income hypothesis predicts consumption is proportional to permanent income, yet empirical elasticities are far below one. I provide evidence that this under-response reflects consumption commitments—hard-to-adjust goods that lock households into past choices. Four facts support this mechanism: consumption elasticity (i) declines with age, (ii) depends negatively on past permanent income growth, (iii) exhibits path-dependent expenditure composition toward easy-to-adjust goods, and (iv) all path dependences disappear among households that recently adjusted commitments. I use a quantitative life-cycle model to show that commitments are necessary to generate the age decline and history dependence. However, commitments are not sufficient to explain the average under-response; bequest motives and late-in-life luxury consumption are also quantitatively important. The calibrated model matches both micro consumption responses and aggregate wealth inequality.

Growing up with an Unemployed Mother

(with Nataliya Gimpelson)(May 2026)

We study the long-term consequences of maternal unemployment for children's labor-market outcomes. Using linked mother-child data from the National Longitudinal Survey of Youth, we document that children exposed to longer maternal unemployment spells have lower wages and employment probabilities as adults. We then unpack these relationships and investigate mechanisms. First, we show that these negative exposure effects are concentrated in adolescence. Second, we explore how mothers change their investment inputs. Third, we highlight how these relations persist after conditioning on family permanent income, suggesting mechanisms beyond income loss. Fourth, we use placebo tests and bunching diagnostics to address selection concerns. Overall, our results provide new evidence on the anatomy of the intergenerational impacts of unemployment and suggest important roles for non-income aspects of unemployment.

The Early Career and the Sources of Lifetime Inequality

(with Xiaonan Ma)(July 2026)

We study the years immediately following labor-market entry and their implications for measuring and understanding lifetime inequality. We estimate a life-cycle model with human-capital accumulation and frictional labor markets using data that follow workers from labor-market entry. We show that decompositions initialized several years after entry substantially overstate the role of initial conditions by reclassifying outcomes generated during the first years of work as initial heterogeneity. We also decompose the rise in early-career wage inequality and find an important role for sorting between human capital and match quality, as workers with higher human capital increasingly obtain better matches. This sorting arises because human capital raises job-finding rates, lowers separation risk, and shifts workers toward better offer distributions, generating incentives to work beyond those arising through wages alone.

Earnings Cuts Upon Transitions and the Role of Stepping-Stone Employers

(with Xiaonan Ma)(July 2026)[New draft coming soon]

This article studies the prevalence and drivers of earnings cuts upon job transitions (ECUTs) in the U.S. labor market. We argue that a significant fraction of ECUTs reflect strategic behavior: workers accept lower initial earnings to join stepping-stone employers -- firms whose departing workers systematically move to higher-paying employers. Using linked administrative data, we show that workers accept larger earnings cuts to join firms with higher upgrading rates and subsequently experience greater wage growth and upward mobility. Using a unique linked administrative-survey dataset, we identify workers' reported motivations for transitions, finding that 29% of transitions motivated solely by pecuniary reasons involve ECUTs and that these workers disproportionately target stepping-stone firms and achieve higher future earnings growth. To formalize this mechanism, we develop a random search model in which employers differ in both the quantity and quality of job-offer arrival rates. The quantitative results suggest that stepping-stone employers, particularly those with higher-quality offer arrival rates, provide an important pecuniary motivation for ECUTs.

Inflation Targeting under Fiscal Fragility

(with Aloísio Araujo, Victor Costa, Rafael Santos, and Serge de Valk)

American Economic Journal: Macroeconomics, April 2026.  

We propose a model to study an inflation-targeting regime under a high government debt burden. We assume that an altruistic policymaker chooses debt issuance, inflation, and public expenditure, while private agents dislike inflation and finance the government. We show that equilibrium inflation depends on debt level: (1) on-target when debt is low; (2) above the target when debt is high; (3) either above or on-target in between, a zone that we named fiscal fragility. Equilibrium inflation also depends on the target level: a higher target may improve welfare by preventing fiscal fragility and reducing debt-rollover costs.

The Quality-Adjusted Cyclical Price of Labor

(with Mark Bils and Marianna Kudlyak)

Journal of Labor Economics, October 2023.  

We estimate cyclicality in labor's user cost allowing for cyclical fluctuations in the quality of worker-firm matches and wages that are smoothed within employment matches. To do so, we exploit a match's long-run wage to control for its quality. Using NLSY data for 1980 to 2019, we identify three channels by which recessions affect user cost: It lowers the new-hire wage; it lowers wages going forward in the match; but it also results in higher subsequent separations. All totaled, we find that labor's user cost is highly procyclical, increasing by more than 4% for a 1 pp decline in unemployment.

Current Constraints on Growth

(with Armando Castelar Pinheiro)

in Antonio Spilimbergo and Krishna Srinivasan (eds.), Brazil: Boom, Bust, and the Road to Recovery, IMF, March 2019.  [Book]

After ranking among the world’s top-performing economies for most of the twentieth century, Brazil entered a prolonged period of low and volatile growth in the early 1980s that shows no sign of ending. This dramatic slowdown reflects a large decline in labor-productivity growth, symptomatic of the Brazilian economy’s inability to move enough workers into higher-productivity jobs despite rising levels of schooling. This chapter discusses three possible explanations for this poor performance: the failure to complete market-oriented reforms, the adoption of industrial policies focused on protecting inefficient incumbents, and the expansion of policies favoring small, unproductive firms. It concludes by highlighting six policy areas for restoring sustained growth.
