Abstract The US tax system allows taxpayers to deduct local taxes from their taxable incomes. Using school district referendum results, we employ a continuous treatment two-way fixed-effects framework to provide causal evidence of a positive relation between the demand for local public goods and the share of residents deducting local taxes. We find that a 1 percentage point decrease in the share of residents deducting property taxes reduces tax and bond referendum approval rates by approximately 0.97 percentage points. Because these federal tax deductions disproportionately benefit higher-income individuals, they potentially widen disparities in public service provision across jurisdictions.

Abstract Despite the continuing U.S. hospital merger wave, it remains unclear how mergers change, or fail to change, hospital behavior and performance. We open the black box of hospital practices through a megamerger between two for-profit chains. Benchmarking the merger's effects against the acquirer's stated aims, we show they achieved some of their goals, harmonizing electronic medical records and sending managers to target hospitals. Postacquisition managerial processes were similar across the merged chain. However, these interventions failed to drive detectable gains in performance. Our findings demonstrate the importance of organizations for merger research in health care and the economy more generally.

Abstract Urban forests are ubiquitous, yet their impacts and values remain largely unknown. We study a massive urban afforestation policy in Beijing that planted 1/3 of a million acres of greenery in less than a decade. We conduct a remote-sensing audit of the program, finding that it contributes to a substantial greening up of the city. This causes significant downwind air quality improvement, reducing average PM2.5 concentration at city population hubs by 4.2%. Rapid vegetation growth unexpectedly led to a 7.4% increase in pollen exposure. Analysis of medical claims data shows that increased aeroallergens triggered emergency room visits, mirroring pollution effects though much less severe. Monetized net health benefits of the program amount to 1.5% of the city’s GDP. Urban forests are only partially capitalized in housing values, with buyers mainly appreciating proximity to green spaces but not the air quality improvements they bring.

Abstract This study explores the relationship between legalized sports gambling, unexpected emotional cues stemming from NFL home team upset losses and reported intimate partner violence (IPV). Using 1995–2022 crime data from NIBRS, replicating and extending Card and Dahl (2011)’s model, we find that legalized gambling increases the impact of upset losses on IPV by 10 percentage points. The e!ect is larger in states with mobile betting, where higher bets were placed, around paydays, and for teams on a winning streak. These results suggest that financial losses from gambling amplify emotional reactions to unexpected team losses.

Abstract We develop a new test for conditional moment restrictions via nonparametric series regression, with approximating functions selected by Lasso. A key novelty of our approach is to account for the effect of the data-driven selection, yielding a new critical value constructed on the basis of a nonstandard truncated-Gaussian asymptotic approximation. We show that the test is correctly sized and attains a well-defined sense of adaptiveness that may result in better power than existing methods. The improvement afforded by the new test is demonstrated in a Monte Carlo study and an empirical application on the conditional evaluation of inflation forecasts.

Abstract This paper documents the bias introduced by attrition of individuals from administrative data with an application to the labor market consequences of postsecondary education. Attrition due to crossstate migration is non-trivial, particularly for high-earners, graduates from selective universities, and certain majors. Consequently, the premium associated with graduating from a most selective university is 23% higher than in-state earnings suggests, though this magnitude differs across context. The impact of obtaining a 2-year CTE credential is also understated, as are earnings differences across majors. Differences in missingness are systematically related to bias in measurement; we evaluate approaches to quantifying that bias.

Abstract We study how public school teachers use paid sick leave. Most US sick leave schemes operate as individualized credit accounts: Paid leave is earned, and unused leave accumulates. We construct a unique dataset of daily leave balances and behavior among 982 teachers for 2010–2018. Sick leave use increases during flu season, and evidence indicates that the average teacher does not use sick leave for leisure, though some subsets of teachers (e.g., the young and inexperienced) do. Usage increases with leave balance; the elasticity is around 0.4. Further, teachers with higher balances are less likely to work sick, particularly during flu season.

Abstract We develop, validate, and quantify a tractable model of multinational firms that connects multinational production (MP) with foreign direct investment (FDI). Firms choose where to produce and how to finance the production. They can access external finance, but capital market imperfections prevent them from relying exclusively on it for affiliate production, giving rise to FDI. The model rationalizes the three-way relationship between MP, FDI, and financial market conditions that we document and leads to novel welfare implications. Quantification of the model highlights the relevance of these welfare implications and the importance of financial factors in shaping the activities of multinationals.

Abstract This study examines the impact of school choice on academic achievement. I use differences in the number of schools across similar Romanian towns, generating variation in school choice for local students, who compete for seats via test scores. I find that more school choice results in increased sorting of students by admission scores across different schools. Sorting widens achievement gaps between high- and low-admission score students. High-scorers having access to better teachers and peer effects are the primary factors explaining these widening gaps. Last, between-school competition via school choice does not increase average achievement levels.

Abstract We show that firms that face higher uncertainty adjust their investment less in response to monetary policy shocks. We find corroborating evidence of this differential effect from firm-level stock returns on FOMC announcement days. Our results are consistent with a real options (or wait-and-see) channel whereby higher uncertainty dampens the response to changes in business conditions. Consistent with this mechanism, the dampening effect is stronger for firms that face higher reversibility.
