Congestion Pricing And Traffic Safety: Evidence From New York City, Mirella Charros

Theses and Dissertations

This paper examines the impact of congestion pricing on motor vehicle collisions in New York City. Using a spatial difference-in-differences approach, the study finds evidence of increased collisions near the congestion boundary, suggesting potential spillover effects and changes in traffic patterns following policy implementation.

Treaty Database Project, Elisabeth Smith

Honors Capstones

International environmental governance is shaped by a complex network of treaties addressing issues such as water, agriculture, air and atmosphere, energy, wild species and ecosystems, mineral resources, and waste and hazardous substances, among many others.. However, information about these agreements is often fragmented across multiple sources, making it difficult for researchers, policymakers, and the public to understand how different treaties relate to one another. This project develops a structured database of environmental treaties that captures key attributes such as thematic focus, geographic scope, participating countries, and implementation mechanisms.

Building on this database, the project also provides an intuitive front-end interface …

Supersuit Up Or Get Left Behind: Why A Personal Agentic Os Is Required For Commercial Viability In The New Economy, Gary Sheng, Ron Roberts

Digital Laboratory: Publisher of Internet Journal

In my first article, The Writing on the Wall, we laid out the case: self-improving AI has arrived, the economy is splitting, and every organization faces an existential choice. This paper answers the question we heard most after that piece: “Okay, I believe you. What do I do on Monday morning?” The answer is your Personal Agentic OS. It is the minimum viable infrastructure that turns you from a passive consumer of AI into a sovereign operator of it. And in April 2026, three events converged to make this the most urgent professional skill in the world: Andrej Karpathy’s LLM …

Competition As A Solution To High Prices And Low Capacity In U.S. Healthcare: A Synthetic Control Analysis Of Certificate Of Need Repeal As A Lever For Hospital Market Reform, Eve Velasquez, Wyatt Greco

School of Public Policy Capstones

The U.S. healthcare system faces dual challenges: rising hospital prices and declining capacity. Between 2000 and 2024, average hospital expenses per adjusted inpatient day increased from approximately $1,000 to over $3,000, while hospital beds per capita declined from 3.11 to 2.45. This capstone evaluates three policy alternatives to address affordability and accessibility: restrictions on most-favored nation clauses in insurance-provider contracts, elimination of federal tax exemptions on employer-sponsored health insurance, and repeal of certificate of need (CON) laws. Through a comprehensive literature review and a synthetic control analysis of Indiana's 2019 nursing home CON reinstatement, we assess the empirical effects on …

A National Security Strategy For The Middle East, Vanessa Rice, Rudy Torres, Addy Horgan, Joy Omosa, Mark Westfall

School of Public Policy Capstones

This National Security Strategy addresses the persistent national security challenges the United States faces in the Middle East, a region vital for global energy supply, economic connectivity, and a source of anti-American extremism. Recognizing the failures of past "haphazard experimentation," the strategy proposes a thoughtful, pragmatic plan prioritizing five distinct and congruent interest areas: Maintaining Regional Access, Supporting Regional Stability, Ensuring Energy Security, Defending American Citizens and Personnel, and Preserving and Protecting Western Ideals. The strategy outlines actions such as: countering Chinese and Russian influence through intelligence sharing and defense incentives; containing Iran via a new, permanent nuclear deal and …

Optometry Associations And The Free Rider Problem Revisited, Matthew Mullis, Joshua Hall, Edgar Orozco

Graduate Student Scholarship

Members of professional associations pay dues to professional associations for a variety of reasons, including lobbying. This can lead to a free-rider problem if non-members enjoy the benefits without paying. Using 2023 data from 30 states, we revisit earlier work on the free-riding problem by analyzing how continuing education requirements, number of optometrists, benefit salience, and legal services affect membership rates. We find no significant relationship between continuing education hours or total optometrists and membership percentages. We introduce two variables measuring selective incentives: salience of advertised benefits and availability of legal services. Legal services exhibit a negative association with membership …

Converting The Social Security Trust Fund Into A Sovereign Wealth Fund: A Proposal To Secure The Future, Keanu Moore

Dartmouth College Master’s Theses

This thesis proposes the conversion of the Social Security Trust Fund into a sovereign wealth fund (SWF), paired with the phased creation of a mandatory retirement savings system for all working-age Americans. In response to forecasts projecting Trust Fund depletion by 2034, the proposed portfolio shift would diversify assets beyond U.S. Treasuries into global equities, real estate, alternatives, and fixed income, with the goal of enhancing long-term returns while remaining passively managed. While this reform would extend the Fund’s solvency, it is not, on its own, a permanent fix. To ensure structural sustainability beyond the exhaustion date, the thesis proposes …

Black Swans And Financial Stability: A Framework For Building Resilience, Daniel J. Barth, Stacey L. Schreft

Journal of Financial Crises

This article refines the concept of black swans, typically described as highly unlikely and catastrophic events, to be internally consistent. It explores features of the financial system that prevent the eradication of black swans. The main implication is the need to enhance the financial system’s resilience to withstand unforeseen events rather than focus on past crises. The article introduces a “resilience principle” for designing official-sector policies that can achieve such goals. The principle calls for policies that are adaptable, universal, and systemic. The article provides examples of policies with these features, assuming that the official sector is not better positioned …

Digital Public Service Delivery As An Institutional Outcome: Data Governance And Interoperability In The Egyptian Public Sector, Waad Hegazy

Theses and Dissertations

Moving beyond technology-centered theories of digital transformation, this thesis examines the institutional and governance factors shaping digital public service delivery in Egypt. It analyzes how governance structures, data governance arrangements, and interoperability frameworks influence the extent to which digital transformation initiatives result in integrated, scalable, and citizen-facing public services. Using a qualitative research design, the study draws on an analysis of relevant policy and program documents and semi-structured interviews with key stakeholders involved in digital transformation initiatives in Egypt. The findings indicate that persistent challenges in digital public service delivery are driven less by technological constraints than by fragmented governance …

Fiscal Decentralization, Foreign Capital, And Economic Development In Sub-Saharan Africa, Kwadwo D. Frempong

Theses and Dissertations--Public Policy and Administration

Economic development in Sub-Saharan Africa has been shaped by two transformative policy shifts: widespread fiscal decentralization reforms transferring revenue and expenditure authority to subnational governments, and the pursuit of foreign direct investment to supplement domestic capital. Despite the breadth of these reforms, their effectiveness in promoting sustainable economic development remains empirically contested. This dissertation examines three interconnected questions about fiscal governance and capital flows in Sub-Saharan Africa: what determines the extent to which governments decentralize fiscal authority; how county fiscal composition and revenue autonomy shape subnational economic performance; and how foreign direct investment interacts with domestic investment and growth.

The Economics Of Accountability: Learning From German Holocaust Reparations, Grace I. Gates

Scripps Senior Theses

Drawing on microdata from the Survey of Health, Aging, and Retirement in Europe, this study compares European Holocaust survivors who received reparations with similar Europeans who did not. It finds that, decades on, recipients are not systematically better or worse off on core outcomes like life satisfaction, savings, and debt. This is consistent with the argument that reparations restore parity rather than create new advantages. Where differences emerge, they point to stabilization in more vulnerable settings (e.g., lower likelihood of high debt in parts of Eastern Europe). The main takeaway from effective reparations is applicable to the United States debate: …

Towards Energy Access For All: Developing The Lived Energy Experience Index (Leei), Kentina Annie Ishimwe

Electronic Theses and Dissertations

Energy is the fuel that powers the engine of civilization. Energy access metrics ensure that nations continuously work towards providing access for all. However, the prevalent binary indicator fails to consider that energy needs to be usable, accessible, affordable, and reliable. As a result, numerous tiered and multidimensional metrics, such as the Multi-Tier Framework, came about to bridge the gap but proved to be complex and complicated to implement. This study presents the existing literature review, assesses the limitations of current energy access measurement frameworks, and compares household energy needs with reported access statistics. Based on the findings, the Lived …

Economic Inequality And Family Formation In The United States, Elizabeth S. Krause

Theses and Dissertations--Economics

This dissertation evaluates economic inequality and family formation in the United States in three essays. In Essay 1, I estimate the effect of providing subsidized access to immediate postpartum contraceptives on birth spacing and infant health among low-income teen mothers. The intent-to-treat estimates indicate a 20% reduction in the monthly short-interval birth rate among teens 12-14 months after policy enactment. I also find evidence that the policy increased the average interval between births and reduced preterm and low-birth weight births and NICU admission rates. In Essay 2, I provide evidence that single mothers and single women without children are important …

Good Food In The Neighborhood: Localizing Nutritious Food Access, Joseph Pool

Honors Program Theses

Given contemporary changes to federal budget priorities and recent challenges to federal food access funding, this research explores the potential benefits of entrusting state-level and municipal-level policymakers with food access policy. More specifically, this research suggests that “localizing” food access has the unique benefit of not just addressing the affordability of food, but the physical accessibility of it. As observed in the previous literature and expounded upon here, food provisioning requires consideration of nutrition, physical accessibility, and financial affordability. Programs that only address one of these priorities fail to adequately help people receive the food they need. Through policy analysis …

Improving Maternal Health: Investigating The Early Impacts Of Medicaid Coverage Of Doulas In Oregon, Miriam Akhmetshin

Scripps Senior Theses

While the U.S. spends more per-capita than any country on healthcare, we experience the worst maternal health outcomes of high-income nations. In addition to hefty healthcare bills, an overwhelming majority of mothers experience pregnancy-related health issues that decrease productivity and utility. Thus, it is critical to research cost-effective solutions that can improve maternal health and promote equitable outcomes. Doulas are trained non-medical professionals who support mothers and families before, during and after birth. As a growing body of medical literature points to the role of doulas in decreasing costly medical interventions, insurance companies have begun covering their services. In 2014, …

Expanding State Tax Authority: Public And Private Sector Impacts Of Wayfair, Maxwell Pastoria

Williams Honors College, Honors Research Projects

The 2018 Supreme Court decision in South Dakota v. Wayfair, Inc. (Wayfair) overturned the longstanding physical presence rule for state sales tax collection, enabling states to enforce tax obligations on remote sellers through marketplace facilitator and economic nexus laws (Oyez, 2018). This study investigates the effects of these two post-Wayfair tax laws on state sales tax revenues, entrepreneurship, and public expenditures across all 50 states. Using a two-way fixed effects difference-in-differences (TWFE DID) framework, this research analyzes how policy adoption influenced per-capita outcomes in tax revenue, firm formation, and government spending in social services, education, infrastructure, and …

Medical And Recreational Cannabis In Colorado: Evidence From County-Level Sales And Medical Cards, Ethan Sattley

CMC Senior Theses

This thesis examines how Colorado’s cannabis market transitioned after recreational legalization by analyzing county-level medical card registrations and the medical share of cannabis sales from 2010–2020. Using an event-study design, I find that medical participation remained stable for several years after recreational sales began in 2014, but then declined sharply, by roughly 50–60 cards per 10,000 residents, about ten quarters after legalization. Using annual sales data, I show that the medical share of total cannabis revenue collapsed much more quickly, falling by more than half between 2014 and 2015 and converging near zero in most counties by the late 2010s. …

The Tcja And Shareholder Payouts, Carson T. Bloom

CMC Senior Theses

Abstract

The Tax Cuts and Jobs Act (TCJA) provided corporations an estimated $233 billion in tax savings, yet relatively little is known about how firms allocated this cash windfall. This study examines whether growth and mature firms differed in whether they used these tax savings to distribute dividends and repurchase shares. Using panel data on publicly traded North American firms from 2016–2019, I classify firms as either growth or mature based on their cash-flow patterns and estimate the effects of the TCJA on their behavior using a difference-in-differences design.

The results indicate that mature firms increased shareholder payouts significantly more …

Three Essays In Labor Economics, Yoritsugu Shimazu

Electronic Theses & Dissertations (2024 - present)

The first chapter decomposes aggregate productivity growth into a pure-technology contribution and an allocative-efficiency contribution for Japan and the United States, applying a single estimation methodology symmetrically to comparable firm-level panels. Production functions are estimated by the Gandhi, Navarro, and Rivers (2020) gross-output procedure under monopolistic competition (GNR-MC), which recovers firm-level price markups and wage markdowns, and these enter the Baqaee–Farhi (2020) decomposition through the closed form of Aoki et al. (2024). Both panels are drawn from Compustat with identical pre-processing and estimation, and we close the markup-level identification gap that GNR leave open with a normalization anchored on the …

Does Immigration Enforcement Induce Legalization? Replicating And Extending The H-2b Evidence To Agricultural Guest Workers, Katherine E. Schwab

CMC Senior Theses

This thesis examines whether intensified interior immigration enforcement leads employers to increase demand for legal temporary foreign workers through the H-2 guest-worker programs. Using updated administrative data from the Office of Foreign Labor Certification, I first replicate the core findings of Amuedo-Dorantes, Arenas-Arroyo, and Schmidpeter (2021), who find that county-level enforcement significantly raises employer demand for H-2B non-agricultural workers, then apply the same empirical framework to H-2A, the agricultural equivalent.

My replication results are directionally consistent with the original study – the enforcement coefficient on H-2B demand is positive across specifications – though weaker in significance, reflecting routine vintage differences …
