Economic Drivers Of International Migration To Türkiye: A Regional Comparison Study, Bekir Gündoğmuş, Musa Bayir, Ahmed Yusuf Sarihan

Makara Human Behavior Studies in Asia

This study investigates the macroeconomic determinants of registered international migration to Türkiye by employing panel data regression techniques at the NUTS-2 regional level for the period 2016–2022. The results reveal that per capita income, employment, and the share of industry, services, and construction sectors in total production have a statistically significant and positive impact on migration inflows, while inflation exhibits a negative effect. However, agricultural production proportion and export performance do not appear to significantly influence regional migrant preferences. Causality tests further support the existence of both bidirectional and unidirectional relationships between economic indicators and migration. The findings underscore the …

A De-Dollarizing World: How Sanctions Catalyze De-Dollarizing Efforts In Russia And China, Karina S. Amaach

Senior Theses

For nearly a century, the United States has occupied the title as the world’s leading superpower nation. Such power has granted the US great economic responsibility, particularly highlighting the dollar’s dominant role as the international reserve and trade currency. However, the rise of competing powers– most notably China and Russia– have posed great threats to this continued economic dominance of the United States. This thesis examines how U.S. economic sanctions– often described as America’s greatest financial tool– have inadvertently motivated de-dollarization efforts led by these two nations. Drawing on interdisciplinary scholarship in foreign affairs, international political economy, and intergovernmental financial …

Essays On Development Economics, Environmental Economics, And Political Economy, Weihong Li

Economics Theses and Dissertations

Chapter 1 explores the strategic behavior of provincial leaders in China in response to visits by central government leaders. I find that such behavior is correlated with provincial leaders’ personal characteristics and their connections with the visitors. Meanwhile, acting strategically during these visits has a positive and significant effect on overall promotions, but a positive and insignificant effect on promotions to the most important positions in the Politburo.

Chapter 2 examines the impact of the Confucian norms on the spatial heterogeneity of fertility rates and sex-selective abortions in contemporary China. To overcome the challenge of quantifying cultural norms, I construct …

Bayesian Spatiotemporal Model For Counterfactual Estimation In Socioeconomic Studies, Duwani W. Gonzalez

Statistical Science Theses and Dissertations

Impact evaluations of regional development programs often require estimating counterfactual outcomes for a small number of treated regions using survey-based areal data. In practice, evaluators typically rely on two-group quasi-experimental methods such as propensity score matching (PSM) and Difference-in-Differences (DiD). These approaches perform poorly when only a few regions receive treatment, and when the set of observed covariates is limited or only partially relevant. Moreover, they typically do not explicitly exploit the spatial and temporal dependence present in survey-based areal data such as in ACS (American Community Survey). This dissertation develops a family of Bayesian spatial predictive models for directly …

Fueling Reactions: Three Empirical Essays On Behavioral Responses, Economic Shocks, And Energy Markets, Euclides Coelho De Medeiros Correia

Economics Theses and Dissertations

This dissertation examines how shocks in energy and commodity markets propagate through local economies and reshape human behavior, spanning three empirical essays that connect energy markets to electoral behavior, commodity price dynamics, and criminal violence.

Beyond Brain Drain: H-1b Visas, Innovation, And Human Flourishing, Joel Wong

Honors Projects

High-skilled migration has become one of the defining features of the modern global economy, especially in technology, engineering, and research-intensive industries. While public debate surrounding the H-1B visa program often centers on its effects within the United States, less attention has been given to how these migration flows affect the countries from which workers originate. This question is important because many sending countries invest heavily in the education and development of highly skilled workers while also seeking long-term economic growth and innovation. This study examines whether increases in H-1B visa migration are associated with changes in innovation outcomes in major …

Shelter From The Storm: Public Library Value And Community Adaptive Capacities, Margo Gustina

Economics ETDs

This dissertation contributes to theoretical framing within the discipline of library science, while building out empirical methods for quantitatively valuing broadly loved public libraries. Chapter 1 lays the foundation for understanding how analysis public libraries must always be set within regional contexts. Chapter 2 demonstrates that positive voter valuation of public libraries is driven by proximity to a library building by using data from public funding referendum events. Chapter 3 estimates a reduction of 0.75 percentage point (p=0.002) in graduation rates where public libraries were closed (but school instruction was in-person) from COVID closures. Chapter 4 builds on the previous …

Perception, Payment, And Pollution- Examining The Effects Of Air Quality On Health And Healthcare, Colin Sleeper

Economics ETDs

Abstract

This dissertation examines how air quality and public attention to environmental shock affect perceived health status and healthcare utilization. The first chapter uses publicly available survey data from BRFSS and a triple difference framework to analyze the effects of the 2018 wildfire season in Oregon on self-reported mental and physical health. Findings indicate that those in Oregon in 2018, during the period of heightened attention to wildfire smoke, experienced approximately 1.4 additional poor mental health days, on average. The second chapter includes Merative MarketScan commercial insurance claims data to test whether these changes translate into a behavioral response. Results …

Agricultural Water Management, Farmer Decision-Making And Climate Adaptation In Dryland Agriculture: A Case Of The Middle Rio Grande Basin, Oluwatosin A. Olofinsao

Economics ETDs

Agriculture in dryland regions faces mounting pressure from climate change, water scarcity, and shifting land-use demands. The Middle Rio Grande Basin (MRGB) of central New Mexico exemplifies these challenges, where irrigated agriculture relies on increasingly variable surface water supplies. This dissertation examines agricultural water use, farmer decision-making, and adaptation strategies across farm types and climate conditions in the MRGB. The first study presents a spatial descriptive analysis of farm size, crop patterns, groundwater access, evapotranspiration (ET), and effective ET, revealing a landscape numerically dominated by smallholder farms that account for a substantial share of irrigation water use. The second study …

Boundaries Of Inequality: The Political Economy Of Redlining And Modern Mortgage Credit, Kyle Guo

Harvey M. Applebaum ’59 Award

This paper investigates the legacy of historical redlining on contemporary access to mortgage credit across three distinct urban policy environments: Baltimore, Philadelphia, and Manhattan. I find that while historical redlining is associated with a statistically significant negative effect on mortgage approval rates, the magnitude of this direct effect is relatively small. In comparison, applicant race, particularly for Black applicants, is a stronger predictor of mortgage approval rates across cities and models. This study utilizes 1930s Home Owners’ Loan Corporation (HOLC) residential security maps and Home Mortgage Disclosure Act (HMDA) data from 2007 to 2017, and uses ordinary least squares (OLS) …

Welcome Tilly Norwood: Forecasting Hollywood’S Ai Policy Futures, Samuel P. Rooker

Senior Honors Projects, 2020-current

In late 2025, weekly trade publication Variety Magazine reported on the announcement of a new acting talent in Hollywood: Tilly Norwood. Norwood is an industry outsider and the pet project of Eline Van der Velden, who unveiled the actress’ existence to the world at the Zurich Film Festival. The announcement quickly gained media coverage while Van der Velden has since faced cyclical backlash from Hollywood trade unions, which does not seem entirely without reason. Tilly Norwood is a digital persona, a generative artificial intelligence (GenAI) program, designed by Van der Velden’s novel AI talent studio, Xicoia, to become the next …

Hammurabi’S Laws: Ancient Traditions Of Violence, Aaron Secrist

The Confluence

The tradition of enforcing private property through violence is truly ancient, and goes back thousands of years to the first civilizations. There exists a prevailing attitude that contemporary culture is more “civilized” than the first organized societies – and while it’s true in some ways, our laws are still remarkably similar to those practiced in antiquity. In the following essay, I analyze the Law Code of Hammurabi and examine its parallels to the way laws function today. First, I will provide context for the technological advances that made the first city-states possible, then give a cultural and economic overview of …

The Effects Of Food Insecurity And Child Health On Educational Achievement In Virginia Counties, Peyton T. Randall

Honors Projects

This study examines the relationship between county-level socioeconomic and demographic factors and student performance on Virginia Standards of Learning (SOL) math and reading assessments in 2023. Using data from 127 of Virginia’s 133 independent counties and cities, this study conducts an ordinary least squares (OLS) regression. The analysis shows a strong negative association between food insecurity, measured by the Identified Student Percentage eligible for free school lunch (ISP), and chronic absenteeism with SOL pass rates. These findings show food insecurity and absenteeism as key drivers for achievement disparities, suggesting a need for further interventions and broader research using school-level and …

Inflation, War Bonds, And Voter Backlash In The 1950s, Gillian Brunet, Eric Hilt, Matthew S. Jaremski

Economics: Faculty Publications

We study the role of war bonds and inflation in post-WWII federal elections. During WWII, the federal government conducted aggressive campaigns to convince Americans to invest their savings in war bonds. After the war, major bouts of inflation in 1946-48 and 1950-51 depressed the bonds’ real returns, provoking widespread frustration. In a difference-in-differences framework, we find that counties with higher war bond purchases shifted their votes towards the Republican Party in the postwar presidential elections. To address concerns related to the endogeneity of war bond purchases, we use an instrumental variables design, and obtain similar results. We also find that …

More Than The Sum Of Its Sexes: Functional Constraints, Embodied Capital, And Age-Structured Labor In Human Forager Economies, Eric Schniter, Hillard Kaplan, Brenda Bowser, Cari Goetz

ESI Publications

"The paper's rough consensus attributes the SDoL to differential variance in food returns across male- and female-typical foraging domains, sourcing this primarily to Bird and Codding (2015) and Kelly's (2013) reframe of the classic 'hunting vs. gathering' axis as 'risky vs. non-risky foraging.' Indeed, the data show that males more often pursue large game and honey, resources that yield higher caloric returns but with high unpredictability, injury risk, and failure rates. Females, especially those with dependent young, more often target plant foods and small game that produce steadier, lower-variance returns. But variance-buffering is a proximate ecological account, not a life …

Early Detection Of Alzheimer's Disease And Related Dementias From Spontaneous Speech Using Foundation Speech And Language Models: Comparative Evaluation, Jingyu Li, Lingchao Mao, Xi Mao, Hairong Wang, Zhendong Wang, Xuelei Sherry Ni

Economics and Finance Faculty Publications

Background: Alzheimer's disease and related dementias (ADRD) are progressive neurodegenerative conditions where early detection is critical for timely intervention and care planning. However, current diagnostic methods are often inaccessible, costly, and delayed, especially for underserved populations. There is a growing need for scalable, noninvasive tools that can support timely diagnosis. Spontaneous speech contains rich acoustic and linguistic markers that can serve as noninvasive behavioral markers for cognitive decline. Foundation models, pretrained on large-scale audio or text data, generate high-dimensional embeddings that encode rich contextual and acoustic information.

Objective: This study benchmarks open-source foundation language and speech models to evaluate their …

Solving Affordability Challenges In Education, Housing And Childcare, Brad J. Hershbein, Michelle Miller-Adams, Brian J. Asquith, Chloe R. Gibbs

Presentations

These three presentations emphasize that affordability challenges across education, housing, and childcare stem from structural market and policy frictions, and that effective solutions require coordinated public investment, simplified systems, and attention to both supply and demand. The first presentation argues that while college tuition growth has slowed and aid has increased, affordability challenges persist due to complexity, misperceptions, and uneven costs, and it advocates for simple tuition-free programs combined with investments in advising, streamlined pathways, and stronger school-to-work connections. The second presentation highlights a growing housing affordability crisis in the Rust Belt driven by aging housing stock and limited supply, …

Measuring The Exorbitant Privilege: A Unified Estimate Of The Financial Benefits Of Dollar Dominance, 1976–2024, Carson T. Weeks

Honors Theses

This paper constructs a unified annual time series of the major measurable components of the United States' exorbitant privilege from 1976 to 2024. Drawing on established econometric estimates from the literature, it measures three channels through which the international role of the dollar generates financial benefits for the United States: seigniorage from foreign holdings of physical currency, borrowing cost savings on federal debt arising from reserve-driven demand for Treasuries, and the return differential on the U.S. external balance sheet, covering both public and private holdings. All dollar figures are reported in real 2024 dollars, deflated by the Consumer Price Index. …

The "Missing Self-Employed": How Better Data Change The Picture Of Self-Employment In The United States, Katharine G. Abraham, Susan N. Houseman, Beth C. Truesdale

Upjohn Institute Policy Papers

How economically secure are self-employed workers? Accurate answers to this question depend on data that capture the full range of self-employed people, including business owners, independent contractors, and those working on an informal, often cash basis. Using data from the 2025 American Job Quality Study, we demonstrate that, because of the way standard survey questions are worded, a substantial number of self-employed people are likely miscoded as employees in existing surveys. Correctly including these “missing self-employed” increases the share of workers who are self-employed on their main job by nearly 50 percent. Compared to the self-employed captured by standard survey …

Centralization Vs. Decentralization: First Evidence From The Laboratory, Gabriele Camera, Gary Charness, Nir Chemaya

ESI Working Papers

The future architecture of financial systems is a subject of contention, with centralized and decentralized governance proponents. Here we ask: would the architecture affect the quality of decision-making? We propose a game where financial network participants demarcate the ownership of claims to income. This governance task can be decentralized (shared authority), centralized (single authority), or hybrid (alternating authority). Without communication all architectures supported poor outcomes. With communication, decentralization ensured good governance and maximum profits, while centralization did not—lowering communication’s potency in promoting socially optimal decisions. This indicates there is scope for decentralization in innovating financial institutions.

Undertaking Short-Term Finance Transactions In Brazil - An Historic And Modern Look At The Brazilian Economy And Associated Risks, Shawn M. D'Aversa

Student Research

The following report discusses the risks and construction of a hypothetical short-term trade finance transaction involving the five parties: Citibank N.A., Caterpillar Inc. (CAT), Banco Do Brasil, Paracatu Gold Mine and EXIM Bank. Fair warning: this is a long paper for a short-term transaction.

For the deal, Caterpillar Inc. (CAT) has approached Citibank N.A. in New York regarding a financing transaction for five 797F-400 short-ton haul trucks. The trucks are worth $5mn each, including the costs of training and spare parts, for a total of $25mn. Put simply, the trucks are beasts for mining. They will then be shipped to …

Climate Policy Uncertainty And Housing Prices: Analyzing Bidirectional Transmission Across U.S. Metropolitan Areas, Sourav Batabyal, Alper Gormus

Finance and Economics

This study examines the relationship between climate policy uncertainty (CPU) and residential housing prices across U.S. metropolitan areas using the U.S. CPU index developed by Gavriilidis in 2021 and monthly S&P CoreLogic Case-Shiller Home Price Indices, covering January 1991 to May 2024. Employing a Fourier-augmented Toda–Yamamoto causality framework that accounts for both abrupt and gradual structural breaks, we document significant CPU → housing prices transmission in multiple metropolitan markets, with bidirectional transmission dynamics emerging in Los Angeles, New York, San Diego, and San Francisco, as well as at the U.S. national level. The results reveal substantial spatial heterogeneity across various …

Resilience In Place Names: German-Hehe War Memories And Cultural Identity In Iringa Toponyms, Claudio G. Kisake, Sophilini M. Yisega, Spemba E. Spemba

Journal of Humanities and Social Sciences

Toponyms, or place names, act as vital markers of historical memory, cultural identity and resilience. In Iringa, Tanzania, toponymy offers valuable insights into the enduring impacts associated with the German-Hehe War (1890–1898), and colonial encounters on indigenous communities. This study explores how place names—such as Kitanzini (‘a place with a noose for hanging people’), Ilundamatwe or Lundamatwe (‘a collection of slaughtered heads’), and Gangilonga (‘the speaking stone’)—convey narratives of Hehe war superiority, resistance, and survival. Using a qualitative approach, the research incorporates archival sources, oral histories, and linguistic analysis to investigate the stories behind naming and renaming, the role of …

A Sturdy Future: Mangrove Restoration Against Climate Extremes, Gabriella Marie Siasoco

Student Theses 2015-Present

This paper addresses the impacts of climate change on natural disasters and examines how rehabilitation of mangrove forests in Mesoamerica and the Caribbean can mitigate those effects. Rising ocean and atmospheric temperatures contribute to higher sea levels and more severe hurricanes and tropical storms, characterized by increased frequency, duration, and intensity in peak winds, storm surges, and rainfall. Mangrove ecosystems act as vital buffers against coastal disturbances such as tsunamis and extreme storms, while contributing to climate change mitigation through carbon sequestration. Additionally, they improve water quality by filtering nutrients, preventing eutrophication. Despite their ecological and economic value, mangroves in …

Solid Waste Management In Greater Khartoum City, Sudan, Roba Mahmoud

Student Theses 2015-Present

This study investigates the rising solid waste management (SWM) dilemma in Greater Khartoum City (GKC), a critical environmental and public health issue caused by fast urbanization and inadequate infrastructure, with historical linkages to Sudan's colonial and postcolonial growth. Chapter 1 describes the current problem using quantitative and qualitative data, demonstrating that GKC produces approximately 3,340 tons of waste each day, with 56% organic matter, 8% plastics, and 16% paper. Collection efficiency remains severely poor, at 31.5%. Informal recyclers known as Nakasha or Barkata collect approximately 7% of total waste, supporting roughly 3,900 people, whereas filthy open dumps and unsorted medical …

Perception Of Asset Price Bubbles In Graphical Data, Cooper P. Vining

Honors Theses

This thesis studies how individuals judge asset price paths and bubbles from graphical data. It primarily investigates whether individuals can differentiate simulated asset price paths that are generated from pure random walks, and graphs that have a bubble element. This question is important because inventors and ordinary people often interpret price paths visually.

To test this, the project creates simulated asset price paths using random walks and bubble multipliers. The survey has four types of graphs: pure random walks, random walks with a 25% bubble, random walks with a 50% bubble, and random walks with a 75% bubble. The graphs …

Controlling Fiscal Destiny: Evaluating The Effect Of State Tax Composition On Resilience During Defined Shock Period, Calloway R. Bills

Honors Theses

State governments operate under strict fiscal constraints that limit their ability to respond to economic downturns through borrowing or monetary policy, making tax composition a key determinant of fiscal stability. This paper evaluates how variation in state tax revenue composition affects fiscal resilience during economic shocks, focusing on the Great Recession. While prior research shows that individual tax instruments differ in cyclicality, less is known about how overall tax structure shapes revenue performance during and after shocks. Using a panel dataset of U.S. states from 1988 to 2024, this study measures resilience through two outcomes: the magnitude of revenue decline …

Assessing College Tuition And Wage Prospects For Careers In Archaeology, Angelina H. Gutierrez

Honors Capstones

The pressures of rising college tuition are raising questions about whether a degree in higher education is worth the return on investment in today's society and economy. This study aims to acknowledge the issues of affording college and the opportunities granted in the face of college wealth premiums from the perspective of the field of archaeology. The college wealth premium is understood as additionalopportunities and increased salaries offered to those with a degree in higher education compared to those without. Using the Midwestern United States as a case study, I discuss the gender/race wage gap, college debt, loan inequity, and …
