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.

Does Public Company Accounting Oversight Board Regulatory Enforcement Deter Low-Quality Audits?

The Accounting Review 2023 98(3), 335-366
Regulatory economics suggests that one benefit of public enforcement is the deterrence of improper conduct. Using a difference-in-differences (DiD) design, we investigate whether a deterrence effect follows the revelation of Public Company Accounting Oversight Board (PCAOB) enforcement. We find that large audit firm offices improve audit quality following enforcement naming another office within their firm while small firm offices improve following enforcement of local small firm competitors, with these responses varying by enforcement type. To understand potential mechanisms for the geographic deterrence effect, we examine the first occurrence of a revoked PCAOB registration within a market and find that results are stronger if there is greater news coverage or if nonsanctioned firms are in closer proximity to the sanctioned auditor. Supplemental tests reveal that results are stronger when nonsanctioned auditor clients are similar to the sanctioned firm’s clientele. Our findings suggest a positive but varied deterrence effect following PCAOB enforcement.

Is Attention Produced Optimally? Theory and Evidence From Experiments With Bandwidth Enhancements

Econometrica 2023 91(2), 669-707 open access
This paper develops and deploys a methodology for testing whether people correctly value tools that reduce attention costs. We call these tools bandwidth enhancements (BEs) and characterize how demand for BEs varies with the pecuniary incentives to be attentive, under the null hypothesis of correct perceptions and optimal choice. We examine if the theoretical optimality conditions are satisfied in three experiments. The first is a field experiment ( n = 1373) with an online education platform, in which we randomize incentives to complete course modules and incentives to utilize a plan‐making tool to complete the modules. In the second experiment ( n = 2306), participants must complete a survey in the future. We randomize survey‐completion incentives and how long participants must wait to complete the survey, and we elicit willingness to pay for reminders. The third experiment ( n = 1465) involves a psychometric task in which participants must identify whether there are more correct or incorrect mathematical equations in an image. We vary incentives for accuracy, elicit willingness to pay to reduce task difficulty, and examine the impact of learning and feedback. In all experiments, demand for reducing attention costs increases as incentives for accurate task completion increase. However, in all experiments—and across all conditions—our tests imply that this increase in demand is too small relative to the null of correct perceptions. These results suggest that people may be uncertain or systematically biased about their attention cost functions, and that experience and feedback do not necessarily eliminate bias.

Taking It to the Limit: Effects of Increased Student Loan Availability on Attainment, Earnings, and Financial Well-Being

American Economic Review 2023 113(12), 3357-3400
Growing reliance on student loans and repayment difficulties have raised concerns of a student debt crisis in the United States, but little is known about the effects of student borrowing on human capital and long-run financial well-being. We use variation induced by recent expansions in federal loan limits combined with administrative data-sets to identify the effects of increased access to student loans on credit-constrained students’ educational attainment, earnings, debt, and loan repayment. Increased student loan availability raises student debt and improves degree completion, later-life earnings, and student loan repayment, while having no effect on homeownership or other types of debt.

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.
