Assistant Professor of Finance
UCLA Anderson School of Management (since 2021)
I am an applied microeconomist with a background in labor economics and finance. My research focuses on new technologies, including Generative AI and robotics, and their impact on firms, labor markets and the economy. I also develop new AI-based tools and methodologies for research in finance and economics, and study housing markets and real estate technology.
Before academia, I worked as a strategy consultant at The Boston Consulting Group on projects implementing data analytics, surveys, and technology transformations.

How do recent advances in Generative AI affect firm value? We construct the first measure of firms' workforce exposures to Generative AI and show that an ``Artificial-Minus-Human'' (AMH) portfolio that is long high-exposure firms and short low-exposure firms earned daily returns of 0.44% in the two weeks following the release of ChatGPT. The labor-exposure effect is more pronounced for firms with greater data assets and is distinct from the effect of firms' product exposures to Generative AI. Highly-exposed workforces can be either substituted for or complemented by Generative AI technologies. We measure whether the exposed tasks are core or supplemental to assess relative substitutability. Examining firms' labor demand and profitability following the release of ChatGPT supports a labor-technology substitution channel for the increases in exposed firms' values that we document.
Abstract: Since ChatGPT’s release in 2022, demand for AI-related skills in finance has grown rapidly, as Generative AI drives significant technological changes in both financial research and the broader economy. We show that financial occupations are highly exposed to the productivity effects of Generative AI, review the literature on the impact of ChatGPT on firm value, and provide directions for future research investigating the impact of this major technology shock. Generative AI also holds great potential as a tool for finance researchers and practitioners: we review and describe innovations in research methods linked to improvements in AI tools, along with their applications. We offer a practical introduction to available tools and advice for researchers in academia and industry interested in using these tools.

What drives inequality in technology adoption among firms? In this study, I provide novel empirical evidence linking two of the biggest technology shocks to firms in the last decade: remote work and generative AI. I develop an IV approach to identify the causal effect of remote work and apply it to detailed job posting data to estimate large positive effects of remote work on generative AI skill demand. Conversely, I provide evidence from a synthetic difference-in-differences approach that firms that were more exposed to generative AI technology reduced their demand for remote workers after ChatGPT was released. I rationalize these results using a task-based model of firm investments in new technology. Moreover, I provide evidence for the mechanism through which this “organizational technology ladder” operates: When firms go remote, they invest in technology skills, which, in turn, enable a more rapid generative AI adoption. Firms that are less able to accommodate remote work because they have lower managerial or communication capabilities, or workers with lower individual decision-making skills, are more likely to adopt generative AI after they go remote, and are more likely to reduce their remote hiring after they are exposed to generative AI tools.

Career progression is important for people's lives and economic decisions. We develop an empirical measure of an occupation's local "career value" - the long-run value of the earnings that will result from working in that job and following the career ladder associated with it. We then document that career values have been stagnating over the 2000-2016 period, in spite of growing wages, due to a deterioration in career mobility. We estimate the effect of robot automation on career values over the same time period and find that one additional industrial robot per 1,000 workers lowered local career values by about 1.5 percent. The reason is that robotization reduces transitions into better-paid occupations and redirects workers toward similar- or lower-paid jobs. The impact is largest in high-manufacturing areas, for mid-experience workers, and for males. Demotions from management jobs that result from robotization are more likely for less-educated workers and for women, who are more likely to respond by upskilling. Declines in career values led to a reduction in housing construction and college enrollment and an increase in Republican vote shares in 2016, which highlights how the career effects of automation shape forward-looking household decisions.
Abstract: Politicians respond to increased robotization in the labor market: we find that the Republican presidential candidate in 2016 targeted campaign visits to areas with high robot exposure and that representatives in high-manufacturing areas shifted their policy positions rightward in response to automation.

We find that increases in employer concentration causally reduce wages, using a new instrument for employer concentration based on changes in large firms' national hiring patterns. We also show that measuring employer concentration within a single local occupation excludes important parts of workers' true labor markets. Moving from the median to the 95th percentile of employer concentration as experienced by workers causally reduces wages by 10.7 log points in low-outward-mobility occupations like registered nurses or security guards, and by 3 log points in high-outward-mobility occupations like bank tellers or counter attendants. We propose a new approach for defining mobility-adjusted labor markets, measuring employer concentration on clusters of local occupations identified through asymmetric mobility patterns (using new, highly granular data on occupational mobility from 16 million resumes). Overall, we estimate that around one in six U.S. workers face wage suppression of 2% or more as a result of employer concentration.

We show that partisan political identity has become an increasingly important determinant of where Americans choose to live. Using individual‑level voter‑registration records for 2012‑2022, we construct county‑to‑county migration flows by party and quantify the degree to which migration is ``politically-aligned''---moving to a county whose presidential vote share matches one’s own party. We use this data to estimate party-specific location preferences in a spatial equilibrium model and find a sharp increase in partisan preferences: in 2020‑2022 a 1 percent rise in a destination's Democratic vote share raises Democratic in‑migration by 1.8 percent and reduces Republican in‑migration by 0.8 percent. This partisan preference by Democratic movers represents a 29% increase relative to 2012‑2015, while Republican movers' partisanship only increased in magnitude by 6\%. This can explain the growth in county‑level partisan segregation, as the share of counties that were similarly attractive to both parties declined substantially during the decade.

We construct a novel dataset tracking households across property purchases covering 25 years of moves within the U.S. We find that information frictions in residential real estate markets cause movers with larger exogenous housing wealth to overpay for their next house, relative to both time varying local prices as well as time invariant characteristics of the property itself. These housing wealth driven overpayments are associated with larger positive price impacts to the immediately surrounding neighborhood and are larger for local movers relative to non-local movers. The aggregate effect of housing wealth inflows is to increase county-level house prices.

How do shocks propagate between city-level housing markets? I propose an explanation based on migration spillovers between U.S. cities. I derive an empirical measure of a city’s migration exposure to other cities, and use the network structure of migration to estimate that a 10 pp house price growth shock in a city’s network causes a 4.3 pp increase in house price growth in the focal city. I show that differences in migration networks can explain differences in local housing cycles, and show that accounting for spillover effects improves the ability to explain housing market effects in multiple applications from the finance literature, including 2002-2006 housing boom dynamics, and the effects of the Covid pandemic.

We study the causal effects of homeownership affinities on tenure choice, household sensitivity to credit shocks, and retirement portfolios. Exploiting exogenous variation in affinities across U.S. immigrants’ countries of origin, we find that a 10pp higher affinity causes a 1.5pp higher homeownership rate in the U.S. Using exogenous credit-supply shocks, we show that high-affinity households are more responsive to credit availability, and less likely to default on mortgage payments. By retirement, high-affinity households realize higher homeownership, greater total wealth, and larger real estate shares in their portfolios. These effects are largely driven by appreciation.
