Who’s Afraid of the Minimum Wage? Measuring the Impacts on Independent Businesses Using Matched U.S. Tax Returns
Abstract A common concern surrounding minimum wage policies is their impact on independent businesses, which are often feared to be less able to bear or pass on cost increases. We examine how these typically small and medium-size firms accommodate minimum wage increases along product and labor market margins using a matched owner-firm-worker panel data set drawn from the universe of U.S. tax records over a 10-year period, and using state minimum wage changes as identifying variation. We find that on average, firms in highly exposed industries do not substantially reduce employment—they do not lay off workers but moderately reduce part-time hiring. Instead, these firms are able to fully finance the new labor costs with new revenues, leaving average owner profits unchanged. Higher wage floors, however, forestall entry, particularly for less productive firms, reducing the number of independent firms operating in these industries by roughly 2%. Yet these industries do not shrink; instead, incumbent responses and strong positive selection among entrants reshape industries that rely heavily on low-wage workers, yielding fewer but more productive firms after the cost shock. We also take a worker-level perspective to examine how potentially vulnerable individuals are affected by minimum wage increases. Using panels of low-earning and young workers, we find that their average earnings rise substantially with the minimum wage, while they are no less likely to be employed. Worker transitions indicate that minimum wage increases boost retention and that worker reallocation from independent firms toward corporations buffers disemployment impacts from reduced hiring at independent firms.

Marginal Returns to Public Universities
Abstract This article studies the returns to enrolling in U.S. public universities by comparing the long-term outcomes of barely admitted versus barely rejected applicants. I use administrative admission records spanning all 35 public universities in Texas, which collectively enroll 10% of all American public university students, to systematically identify and employ decentralized cutoffs in SAT/ACT scores that generate discontinuities in admission and enrollment. The typical marginally admitted student gains an additional year of education in the four-year sector, becomes 12 percentage points more likely to ever earn a bachelor’s degree, and eventually earns 8% more than their marginally rejected but otherwise identical counterpart. Marginally admitted students pay no additional tuition costs thanks to offsetting grant aid; cost-benefit calculations show internal rates of return of 26% for the marginal students themselves, 16% for society (which must pay for the additional education), and 7% for the government budget. Earnings gains are similar across admitting institutions of varying selectivity, but smaller for students from low-income families, who spend more time enrolled but complete fewer degrees and major in less lucrative fields. Finally, I develop a method to separately identify effects for students on the extensive margin of attending any university versus those on the margin of attending a more selective one, revealing larger effects on the extensive margin.
Enlightenment Ideals and Belief in Progress in the Run-up to the Industrial Revolution: A Textual Analysis
Abstract We trace the evolution of the language of science, religion, and political economy in the centuries leading to the British Industrial Revolution. Using textual analysis of 264,443 works printed in England between 1500 and 1900, we test whether British culture manifested a belief in progress associated with science and industry. Our analysis yields three main findings. First, there was a separation in the languages of science and religion beginning in the mid-eighteenth century. Second, volumes using language at the nexus of science and political economy became more progress-oriented during the Enlightenment. Third, volumes using industrial language—especially those at the science-political economy nexus—were more progress-oriented beginning in the eighteenth century.

Republican Support and Economic Hardship: The Enduring Effects of the Opioid Epidemic
Abstract In this article, we establish a causal connection between two of the most salient social developments in the United States over the past decades: the opioid epidemic and the political realignment between the Republican and Democratic parties. Drawing on unsealed records from litigation against Purdue Pharma, we uncover rich geographic variation in the marketing of prescription opioids that serves as a quasi-exogenous source of exposure to the epidemic. We use this variation to document significant increases in drug-related mortality and greater reliance on public transfer programs. This induced economic hardship led to substantial changes in the political landscape of the communities most affected by the opioid epidemic. We estimate that from the mid-2000s to 2022, exposure to the opioid epidemic continuously increased the Republican vote share in House, presidential, and gubernatorial elections. By the 2022 House elections, a one-standard-deviation increase in our measure of exposure led to a 4.5 percentage point increase in the Republican vote share. From 2012 until 2022, this increase in the House vote share translated into Republicans winning additional seats.

Permanent Capital Losses after Banking Crises
Abstract We study the mechanisms driving bank losses across historical banking crises in 46 economies and the effectiveness of policy interventions in restoring bank capitalization. We find that bank stocks experience large, permanent declines at the onset of crises. These losses predict commensurate long-term declines in banks’ earnings and dividends, rather than elevated future equity returns. Bank losses are primarily driven by write-downs of nonperforming assets, not asset sales during panics. Forceful liquidity-based interventions during crises predict only small, temporary increases in bank market value. Overall, these results suggest that bank losses during crises are not primarily due to temporary price dislocations. Early liquidity interventions can avert banking crises, but only under specific conditions. Once large bank equity declines have occurred, policy responses have historically failed to prevent persistent undercapitalization in the banking sector.

Diversifying Society’s Leaders? The Determinants and Causal Effects of Admission to Highly Selective Private Colleges
Abstract We use anonymized admissions data from several colleges linked to income tax records and SAT and ACT test scores to study the determinants and causal effects of attending Ivy-Plus colleges (Ivy League, Stanford, MIT, Duke, and Chicago). Children from families in the top 1% are more than twice as likely to attend an Ivy-Plus college as those from middle-class families with comparable SAT/ACT scores. Two-thirds of this gap is due to higher admission rates for students with comparable test scores from high-income families; the remaining third is due to differences in rates of application and matriculation. In contrast, children from high-income families have no admissions advantage at flagship public colleges. The high-income admissions advantage at Ivy-Plus colleges is driven by three factors: (i) preferences for children of alumni, (ii) weight placed on nonacademic credentials, and (iii) athletic recruitment. Using a new research design that isolates idiosyncratic variation in admissions decisions for waitlisted applicants, we show that attending an Ivy-Plus college instead of the average flagship public college increases students’ chances of reaching the top 1% of the earnings distribution by 50%, nearly doubles their chances of attending an elite graduate school, and almost triples their chances of working at a prestigious firm. The three factors that give children from high-income families an admissions advantage are uncorrelated or negatively correlated with postcollege outcomes, whereas academic credentials such as SAT/ACT scores are highly predictive of postcollege success.
Bargaining and Inequality in the Labor Market
Abstract We use novel surveys of firms and workers, linked to administrative employer-employee data, to study the prevalence and importance of individual bargaining in wage determination. We show that simple survey questions accurately elicit firms’ bargaining strategies. Using the elicited strategies for 772 German firms, we document that the majority of firms are willing to engage in individual wage bargaining. Labor market factors predict firms’ strategies better than firm characteristics. Survey responses from nearly 10,000 full-time workers indicate that most workers provide their salary expectations before they receive a job offer. Most outside offers are rejected, with the worker remaining at the incumbent firm. There is substantial heterogeneity in workers’ bargaining behavior, which translates into within-firm wage inequality. Firms that set pay via individual bargaining have a 3 percentage point higher gender wage gap.

Digital Distractions with Peer Influence: The Impact of Mobile App Usage on Academic and Labor Market Outcomes
Abstract Concerns about excessive mobile phone use among youth are mounting. We present estimates of behavioral and contextual peer effects, along with comprehensive evidence on how students’ own and their peers’ app usage affect academic performance, physical health, and labor market outcomes. Our analysis draws on administrative data from a Chinese university covering three student cohorts over four years. We exploit random roommate assignments, differential exposure to a policy shock (gaming restrictions for minors), and differential exposure to a discrete event (the introduction of a blockbuster video game) for identification. App usage is contagious: a one s.d. increase in roommates’ in-college app usage raises own usage by 5.8%. High app usage is harmful across all measured outcomes. A one s.d. increase in app usage reduces GPAs by 36.2% of a within-cohort-major s.d. and lowers wages by 2.3%. Roommates’ app usage reduces a student’s GPA and wages through both disruptions and behavioral spillovers, generating a total negative effect that exceeds half the magnitude of the impact from the student’s own app usage. Extending China’s three-hour-per-week gaming restriction for minors to college students would boost their initial wages by 0.9%. High-frequency GPS and app usage data show that heavy app users spend less time in study halls, are more frequently late or absent from class, and get less sleep.

The Price of Housing in the United States, 1890–2006
Abstract We construct the first annual market rent and home sales price series for American cities over the twentieth century using 2.7 million newspaper real estate listings. Our findings revise several stylized facts about U.S. housing markets. Real market rents did not fall during the postwar period in most cities and rose nationally by 60% from 1890 to 2006. We also document higher sales price growth between 1953 and 1987 relative to previous series. Real prices reached almost four times their 1890 level by 2006. Prices grew most in metros with high demand and low levels of construction. We find that the rent-to-price ratio fell from about 8% in the early twentieth century to 3% by 2006, consistent with declines in the cost of owning housing relative to renting. For the typical year in our period, the annual return to owning housing was 9%, driven mostly by rental returns of 7.7%, with capital gains contributing only 1.3%. While capital gains were close to zero from 1890 to 1940, they grew to nearly a third of total returns from 1970 to 2006.

Vanguard: Black Veterans and Civil Rights After World War I
Abstract Nearly 400,000 Black men were drafted into the National Army during World War I, where they toiled primarily as menial laborers in segregated units. Leveraging novel variation from the World War I draft lottery and millions of digitized military and NAACP records, we document the pioneering role these men played in the early civil rights movement. Relative to observably similar individuals from the same draft board, Black men randomly inducted into the Army were significantly more likely to join the nascent NAACP and become prominent community leaders in the New Negro era. We find little evidence that these effects are explained by migration or improved socioeconomic status. Rather, corroborating historical accounts about the catalyzing influence of institutional racism in the military, we show that increased civic activism was driven by soldiers who experienced the most discriminatory treatment while serving their country.
