The Supply-Side Effects Of Air Pollution On Local Non-Polluting Industries, Erin Hyman
Theses and Dissertations
This paper examines the relationship between PM2.5 and the production of goods and services across industries using a county–industry panel (1999–2013). Fixed effects regressions show higher activity in manufacturing but relative declines in non-polluting sectors, suggesting pollution reflects production intensity and a reallocation toward polluting industries.

The Effect Of Inbound Tourism On Consumer Prices In Japan, Serenity E. Thompson
Theses and Dissertations
This paper uses monthly prefectural data to estimate the effect of inbound tourism on Japan’s consumer prices. Results indicate that a 10% increase in foreign overnight stays is associated with a 0.01% increase in capital city prices. The paper discusses localized dual pricing as a response to these price pressures.

The Effect Of Prenatal Substance Use Policies On Women's Well-Being, Zukruf Alam
Theses and Dissertations
This paper examines the effects of punitive and priority treatment policies relating to the use of illicit substances during pregnancy on women's health and health-related behavior. Punitive interventions criminalize substance use during pregnancy, which can even lead to termination of parental rights. In contrast, priority treatment policies support pregnant women and grant them priority access to substance use disorder treatment programs. I use staggered difference-in-differences methods and data from the Behavioral Risk Factor Surveillance System data from 2004 to 2018 to estimate the impact of prenatal substance use policies on women's mental health, physical health, self-reported poor health, and cigarette …
Private Equity, State Enforcement, And Arbitration Outcomes Under The No Surprises Act: Evidence From Air Ambulance Disputes,

Private Equity, State Enforcement, And Arbitration Outcomes Under The No Surprises Act: Evidence From Air Ambulance Disputes, Peter Readman
Theses and Dissertations
The No Surprises Act (NSA) removed patients from responsibility for out-of-network surprise medical bills. In its place, the NSA established an independent dispute resolution (IDR) process through which providers and insurers submit competing payment offers to an arbitrator, who selects one offer in full. Using the universe of federal air ambulance IDR disputes from Q1 2023 through Q2 2025 (57,368 dispute line items), I examine whether provider ownership structure and enforcement jurisdiction jointly predict arbitration outcomes. The two outcomes, whether the provider offer prevails, and how large that prevailing offer is relative to the benchmark payment rate, the Qualifying Payment …

Air Pollution And Self-Reported Health Outcomes In The United States, Alina Dervisevic
Theses and Dissertations
This study examines the relationship between short-term PM2.5 exposure and self-reported health outcomes among U.S. adults using BRFSS data from 2000 to 2012 linked to county-level pollution and weather data. Results show that PM2.5 exposure is associated with worse mental health and gender specific behavioral responses.
Manipulation Or Monetization?: The Rise Of Stock Buybacks And Their Effects On Firm Valuation And Investment,

University of Arkansas, Fayetteville
Manipulation Or Monetization?: The Rise Of Stock Buybacks And Their Effects On Firm Valuation And Investment, Thomas H. Serrano
Economics Undergraduate Honors Theses
Abstract:
This thesis uses basic econometrics to examine the relationship between stock buybacks, firm valuation, and investment among publicly traded firms from 2000-2024. Using firm-level data pulled from Compustat North America and a fixed-effect multivariate regression, it evaluates whether buybacks are associated with higher valuation and stronger productive investment as defined in the paper. The results show that buybacks are positively associated with firm valuation the first year that they occur, but the relationship disappears when they are lagged for a year. Furthermore, the analysis does not find strong statistical evidence that repurchases are associated with changes in investment, or …

Herding In Artificial Intelligence, John Cotter
Honors Scholar Theses
This paper examines whether increased attention to artificial intelligence (AI) influences herding behavior in financial markets. As AI has become a dominant theme in both financial markets and public discourse, understanding how investor attention affects behavior has become increasingly important. Herding behavior is measured using the Cross-Sectional Absolute Deviation (CSAD) methodology developed by Chang, Cheng, and Khorana (2000). The analysis uses daily data from December 2019 through November 2025 and focuses on the Global X Artificial Intelligence & Technology ETF (AIQ) as a proxy for the AI sector. Investor attention is measured using a composite Google Search Volume Index (SVI) …
Fascism Usa: Class And Identity Politics In The Age Of Trump,

CUNY Graduate Center
Fascism Usa: Class And Identity Politics In The Age Of Trump, Marc Edelman
Publications and Research
This essay argues that Trump’s triumph in the 2024 presidential contest represents the consolidation of an oligarchical authoritarian project, backed by a multi-class and (surprisingly, for some) multi-racial electorate. It brought intensified state and freelance attacks on immigrants, labor unions, women, LGBTQ+ people, journalists, civil servants, assorted “political enemies,” and other groups that the MAGA movement targets. It is institutionalizing authoritarian governance structures in ways that will be exceedingly difficult to undo. The paper first addresses the experience of growing up in the shadow of fascism. It analyzes various sectors that supported Trump and the impacts of inflation, incumbency, economic …

Learning From 2002: County-Level Economic Analysis Of The Salt Lake City Winter Olympics And Implications For Utah 2034, Ronan Spencer
Undergraduate Honors Capstone Projects
This paper examines economic and distributional impacts and the existing literature on the 2002 Salt Lake City Winter Olympics to inform policy recommendations for the upcoming 2034 Utah Olympic Games. Using a difference-in-differences (DiD) framework on county-level data from 1995 to 2006, we compare Utah host counties to Colorado counties. Results indicate that the Games generated an average of 1,084 Leisure and Hospitality jobs per host county, suggesting approximately 5,420 total jobs across all five host counties. We saw a positive but marginally significant increase in tourism and hospitality GDP of $37.2 million relative to Colorado controls (p=0.078). We also …
Restorative Justice In Cache Valley: Building Community Resilience Through Restorative Practices,

Restorative Justice In Cache Valley: Building Community Resilience Through Restorative Practices, Rivkah Haubner
Undergraduate Honors Capstone Projects
Restorative justice as a field of study is primarily applied to criminal justice proceedings or similar topics. As such, its use as a tool in political organizing is an underdeveloped field. Due to its Indigenous history, restorative justice has intrinsically ant-colonial, anti-imperial, and anti-racist roots and is therefore already situated within the ethos of many progressive movements. Historically, radical movements within the United States and across the world experienced both internal and external pressures that undermined their goals. Restorative justice offers a framework through which to understand political action as a whole and specific tools to address internal conflict within …

Two Essays On Finance: The Dark Side Of The Ceo Inside Debt: Evidence From Stock Price Crash Risk And Cybersecurity Risk And Corporate Bond Yield Spreads, Amir Gholami
Theses and Dissertations
This dissertation comprises of two papers. In the first paper, I found that despite being thought of as a governance mechanism, CEO inside debt seems to distort firms’ information environment. My results indicate that the CEO inside debt creates an incentive for managers to hoard bad news to prevent technical defaults, leading to increasing stock price crash risk. My results are robust after addressing endogeneity using the instrumental variable (IV) approach, a difference-in-differences test based on the implementation of Internal Revenue Code Section 409A Final Regulations, and Oster’s omitted variable diagnostic test, and selection bias using the propensity score matching …

Two Essays On Finance: Co-Opted Directors And Mergers And Acquisitions And The Impact Of Biodiversity Risk On The Cost Of Bank Loans, Fariba Gholami
Theses and Dissertations
This dissertation comprises of two papers. In the first paper, co-opted board members, those appointed after the CEO assumes office, are poor monitors and, contrary to prior assumptions, ineffective advisors. I show that board co-option is associated with suboptimal merger and acquisition (M&A) decisions, adverse deal characteristics, and lower acquirer’s short- and long term returns and operating performance. These results are robust to the use of propensity score matching, entropy balancing, Instrumental variable using 2SLS, and difference-in-differences to address selection bias and endogeneity. Cross-sectional evidence indicates that the negative effects of board co-option are more pronounced when boards are less …

The Macroeconomics Of Intergenerational Mental Health Dynamics, Boaz Abramson, Job Boerma, Diego Daruich, Aleh Tsyvinski
Cowles Foundation Discussion Papers
We develop a quantitative macroeconomic theory of child mental health. The theory is grounded in child psychiatry, formalized in a life-cycle heterogeneous agent model of child development, and disciplined using micro data on mental health of children and parents. Intergenerational transmission of mental illness arises due to both biological factors and parental behavior. Parents experiencing mental illness have negative expectations and lose time due to rumination. As a result, they invest less in their child’s mental health. We use the model to evaluate policies designed to improve child mental health. We show that subsidizing mental health treatment for children generates …

Position: The Pre/Post-Training Boundary Should Govern Ip In Industry–Academia Ml Collaborations, Dirk Bergemann, Soheil Ghili, Nitzan Mekel-Bobrov
Cowles Foundation Discussion Papers
Industry–academia ML collaborations routinely fail to launch—not for scientific reasons, but because academics must publish while companies must protect models trained on proprietary data, and no standard contract framework resolves this tension. Because contracts are negotiated by legal departments alone, many apparent legal disputes are incentive misalignment problems that only scientists at the table can correctly diagnose. We propose PBOS (Protect-the-Business / Open-Source-the-Science), a community-adoptable contract template anchored to a single technically-grounded boundary: pre-training artifacts (architectures, training code, benchmarks, untrained weights) are open science; post-training artifacts (weights trained on proprietary data) are business IP. This boundary is technically meaningful, legally …

Class Peers As Competitors And Educators: The Consequences Of Rank-Based Academic Rewards, Mark R. Rosenzweig, Bing Xu
Cowles Foundation Discussion Papers
This paper examines the theoretical and empirical consequences of rank-based reward systems in schools in which students’ performance and effort are evaluated relative to their peers. In such environments, classmates act simultaneously as competitors—due to rank-determined rewards—and as educators through peer learning and assistance. Using nationally representative panel survey data from U.S. high schools, combined with administrative information on the location assignments of new refugee student cohorts, we exploit variation in school competition policies and class ability compositions to identify empirically their dual effects on student effort and peer learning. We develop a theoretical tournament model with heterogeneous students who …

Regional Economic Impacts And Emission Responses Under Solar Radiation Modification, Jenny Bjordal, Evelien Van Dijk, Henri Cornec, Anthony A. Smith Jr, Trude Storelvmo
Cowles Foundation Discussion Papers
Solar Radiation Modification (SRM) has been proposed as a potential tool to limit increases in global or regional temperatures caused by anthropogenic greenhouse gas emissions. While previous research has extensively examined the climate system’s response to various SRM strategies, as well as their aggregate economic consequences, the regional distribution of economic impacts has received less attention. In this study, we use NorESM2–DIAM—an Earth System Model coupled to a high-resolution integrated assessment model—to assess the economic impacts, measured in GDP per capita, in an idealised SRM scenario where incoming solar radiation is reduced by 1%. Our results suggest that, relative to …

Beyond Exposure: Predicting Ai Adoption Based On Comparative Advantage, Ilse Lindenlaub, Ryungha Oh, Maria Alejandra Rodriguez, Laura Veldkamp
Cowles Foundation Discussion Papers
We document and explain the gap between measures of AI exposure and measures of AI adoption in the workplace. This leads us to propose a new AI adoption index based on comparative advantage. Using the representative German DiWaBe employee survey linked to worker and establishment information, we compare worker-reported AI use to prominent exposure measures and find that the relationship is weak. Motivated by this gap, we develop a framework in which adoption depends not only on technical feasibility—AI’s absolute advantage measured by exposure—but on profitability—AI’s comparative (dis)advantage relative to a specific worker—balancing AI productivity against AI user costs and …

Towards A Methodology For Measuring Rental Property Ownership In The United States, Stephanie Kestelman, Rebecca Diamond, John Eric Humphries, Kate Pennington, Winnie Van Dijk, John Voorheis
Cowles Foundation Discussion Papers
Roughly one-third of U.S. households rent their homes, yet measuring who owns rental property is difficult: ownership is frequently obscured by LLCs, partnerships, and other intermediary entities that separate legal from economic control. We develop a method that traces ownership through administrative records—combining deeds and property assessments with the Census Bureau’s Business Register, IRS Schedule K-1 filings, and SEC filings on REITs—to identify ultimate owners and construct property portfolios across the full landlord size distribution. Applying the method to 11 large CBSAs, we find that individual landlords own a large majority of rental units, though their share varies meaningfully across …

Cowles Foundation Discussion Papers
How does wartime rebel governance shape post-conflict institutions? We study this in Nepal, where the Maoist People's War (1996–2006) dismantled a 240-year caste-based monarchy and ended with Maoists entering democratic politics. During the conflict, Maoists established sub-national “People’s Governments” that administered justice, collected taxes, and delivered local services. Using a spatial regression-discontinuity design, we show that exposure to People's Governments increased political knowledge and participation especially among historically marginalized indigenous groups (Janajatis). Exposure also reshaped party institutions and inter-party competition: candidate-selection committees in more exposed areas have 26 percent more Janajati members who, drawing on novel implicit-attitude data, exhibit less …
