When Investor Incentives and Consumer Interests Diverge: Private Equity in Higher Education

Review of Financial Studies 2020 33(9), 4024-4060
We study how private equity buyouts create value in higher education, a sector with opaque product quality and intense government subsidy. With novel data on 88 private equity deals involving 994 schools, we show that buyouts lead to higher tuition and per-student debt. Exploiting loan limit increases, we find that private equity-owned schools better capture government aid. After buyouts, we observe lower education inputs, graduation rates, loan repayment rates, and earnings among graduates. Neither school selection nor student body changes fully explain the results. The results indicate that in a subsidized industry, maximizing value may not improve consumer outcomes.

Owner Incentives and Performance in Healthcare: Private Equity Investment in Nursing Homes

Review of Financial Studies 2024 37(4), 1029-1077
Amid an aging population and a growing role for private equity (PE) in the care of older adults, this paper studies how PE ownership affects U.S. nursing homes using patient-level Medicare data. We show that PE ownership leads to a patient cohort with lower health risk. However, after instrumenting for the patient-nursing home match, we find that PE ownership increases mortality by 11%. Declines in measures of patient well-being, nurse staffing, and compliance with care standards help to explain the mortality effect. Overall, we conclude that PE has nuanced effects with adverse outcomes for a subset of patients.

All Clear for Takeoff: Evidence from Airports on the Effects of Infrastructure Privatization

Review of Financial Studies 2026 open access
We study privatization and corporate ownership in transportation infrastructure, focusing on global airports. Privatization in general does not improve performance. However, private equity (PE) ownership has strong and persistent positive effects on efficiency, volume, and quality, with positive externalities for the local economy. We address selection using close auctions where PE and non-PE firms bid. PE funds expand physical capacity and encourage larger planes while adding low-cost carriers and international routes. They are especially effective in countries with more corruption or state-owned flag carriers. In contrast, the poorer performance of non-PE acquirers may reflect private benefits and historical state ties.

Lender Automation and Racial Disparities in Credit Access

Journal of Finance 2024 79(2), 1457-1512
Process automation reduces racial disparities in credit access by enabling smaller loans, broadening banks' geographic reach, and removing human biases from decision making. We document these findings in the context of the Paycheck Protection Program (PPP), where private lenders faced no credit risk but decided which firms to serve. Black‐owned firms obtained PPP loans primarily from automated fintech lenders, especially in areas with high racial animus. After traditional banks automated their loan processing procedures, their PPP lending to Black‐owned firms increased. Our findings cannot be fully explained by racial differences in loan application behaviors, preexisting banking relationships, firm performance, or fraud rates.

Cutting the Innovation Engine: How Federal Funding Shocks Affect University Patenting, Entrepreneurship, and Publications

Quarterly Journal of Economics 2023 138(2), 895-954
This article studies how federal funding affects the innovation outputs of university researchers. We link person-level research grants from 22 universities to patents, publications, and career outcomes from the U.S. Census Bureau. We focus on the effects of large, idiosyncratic, and temporary cuts to federal funding in a researcher’s preexisting narrow field of study. Using an event study design, we document that these negative federal funding shocks reduce high-tech entrepreneurship and publications but increase patenting. The lost publications tend to be higher quality and more basic, whereas the additional patents tend to be lower quality, less general, and more often privately assigned. These federal funding cuts lead to an increase in private funding, which partially compensates for the decline in federal funding. Together with evidence from industry-university contracts, the results suggest that federal funding cuts shift university research funding from federal to private sources and lead to innovation outputs that are less openly accessible and more often appropriated by corporate funders.

Investor Tax Credits and Entrepreneurship: Evidence from U.S. States

Journal of Finance 2023 78(5), 2621-2671
Angel investor tax credits are used globally to spur high‐growth entrepreneurship. Exploiting their staggered implementation in 31 U.S. states, we find that they increase angel investment yet have no significant impact on entrepreneurial activity. Two mechanisms explain these results: crowding out of alternative financing and low sensitivity of professional investors to tax credits. With a large‐scale survey and a stylized model, we show that low responsiveness among professional angels may reflect the fat‐tailed return distributions that characterize high‐growth startups. The results contrast with evidence that direct subsidies to firms have positive effects, raising concerns about promoting entrepreneurship with investor subsidies.
