About
I am a PhD candidate at the MIT Sloan School of Management, affiliated with the Institute for Work and Employment Research. I study work, organizations, and inequality. My research examines how firms organize work—how jobs and tasks are designed, and how they change in response to consumer markets and technology—and how these employment strategies shape pay inequality between firms and workers. My work draws on restricted-access administrative data, mobile location records, online job postings, and resume data, often in novel combinations.
I am on the 2026–27 academic job market. My CV is available here.
Job Market Paper
“From Wallets to Wages: Consumer Income, Job Design, and Pay Disparities”

Pay differences between organizations are a key source of wage inequality. I propose a novel
perspective on these differences by theorizing that firms serving different consumers create
systematically different kinds of jobs. Firms that serve high-income consumers specialize
jobs into higher-paying and higher-skilled positions focused on quality, while those that serve
lower-income consumers emphasize cost minimization by requiring workers to perform a wider
range of general tasks. Matching consumer foot traffic data and establishment-level wage
records, I find that establishments serving higher-income consumers pay their workers more.
This effect holds comparing among establishments in the same neighborhoods and industries.
Longitudinally, establishments increase wages when they shift toward higher-income customers.
Analysis of online job postings further reveals that jobs at higher-income-serving firms involve
a narrower set of tasks that command higher market value. These findings show how consumer
markets shape firms’ internal job design and contribute to pay inequality across organizations in
the service economy.

“Rising Wages and the Decline of Low-wage Work.”
Accepted, American Sociological Review. (*equal first authorship)
From 2014 to 2024, the share of US hourly workers paid below $15 in real terms fell by
two-thirds, from 38% to 13%. Why? We first distinguish entry and exit from organizational
changes among incumbent employers. Organizational changes can, in turn, be imposed on
employers by external constraints, like labor market tightness, or emerge from the pursuit
of new opportunities. Using restricted-access panel data drawn from administrative records
and job reviews, we bring this framework to bear on the recent wage gains at the bottom of
the labor market. Contrary to creative-destruction predictions, employer exit contributed
little to rising pay at the bottom. Low-paying employers of low-wage occupations contracted,
but the main driver of rising pay was low- and middle-paying incumbent employers of low-wage
occupations increasing pay. These gains in low-wage occupations were associated with
tightening labor markets and increased minimum wages. But over and above these external
constraints, employers also pursued new opportunities for reorganizing work in low-skill
jobs. Notwithstanding organizational inertia, major gains for workers’ pay can come from
changes in existing workplaces.
“Declining Inequality and Persistent Inequality Structures.”

Prior research finds that rising labor market inequality in the United States was abetted
by structural changes in the economy: a consolidation of occupation and organizational bases
of advantage; rising within-job inequality; and declining pay and employment in middle-earning
jobs. In this article, we revisit these structural changes by asking whether they have been
reversed as labor market inequality fell over the last decade. Drawing on restricted-use
microdata from the Occupational Employment and Wages Statistics, we find that declining
inequality is due to declining inequality in occupation premiums. There has been only a small
reversal of consolidation and no decrease in inequality within jobs. Low-wage jobs gained on
shrinking middle-earning occupations, further eroding union, manufacturing, and public sector
wage premiums. These findings demonstrate a novel configuration of labor market inequality,
in which pay rose in low-wage jobs, but underlying inequality structures in the economy
persisted.
Working Papers
“Corporate Minimum Wages and Working Poverty.”
Revise & Resubmit, ILR Review.
Starting in 2014, large US retail and warehouse employers began publicizing new voluntary
corporate minimum wages. These minimums provided a new wage floor affecting millions of
workers. We draw on novel employer-linked household panel data to investigate the impact of
this new organizational policy on workers. Corporate minimums effectively reduce low-wage
work and narrow pay gaps within organizations. These policies deliver substantial reductions
in covered workers’ likelihood of poverty. Working poverty at adopting firms falls sharply
by 30% to 50%, relative to workers in similar jobs, labor markets and competitor employers.
Poverty reduction is not explained by shifting worker selection, pre-trends, or offsetting
decreases in hours or health insurance. However, adopters employ more college-educated
workers and intensify work. These findings show that wage-setting decisions by large
employers have substantial social consequences, shaping inequality at the bottom of the
labor market.
Work in Progress
“Technological Change and the Reorganization of Work.”
Links resume and patent data to show that new technologies concentrate affected tasks within the jobs that perform them, and that this reorganization limits workers’ upward mobility, as workers shed the tasks that help them climb job ladders.
