Symmetry, Presumptions, And The Judges Design, Murat C. Mungan
Faculty Scholarship
An instrumental variables approach called ‘the judges design’ used frequently in social sciences relies on an assumption called ‘average monotonicity’. This assumption pertains to how different judges’ (or other classifiers’) decision making processes relate to each other. Violations of it are hard to detect, which raises the importance of it being supported by a plausible theory. Decisions of judges who solve Bayesian decision problems violate average monotonicity as long as the signals they process are symmetric and they do not possess strong presumptions. This result is extended to cases where judge presumptions are symmetrically distributed and may include strong presumptions. …
Two Essays On Geopolitical Risk And Investment Decisions,

Two Essays On Geopolitical Risk And Investment Decisions, Jie Hu
Graduate Studies Theses and Dissertations 2026
My first essay studies how global institutional investors adjust cross-country equity allocations in response to rising geopolitical risk. Using quarterly equity holdings of institutional investors over 1997–2023, combined with news-based global and country-specific geopolitical risk indices, I find that following increases in geopolitical risk within a country, foreign institutions actively reduce their allocations in that country and the nearby region. Elevated global geopolitical uncertainty triggers both a flight-to-home response toward domestic equities and a flight-to-safety effect toward U.S. equities. Investor responses are heterogeneous: Institutions with higher geopolitical risk sensitivity respond more aggressively, whereas larger or better-performing hedge funds often maintain …

The Impact Of Student Achievement On Economic Growth: A Pisa-Based Analysis Of Gdp Per Capita, Emma Rose Nasr
Undergraduate Theses and Capstone Projects
This study investigates the extent to which international student achievement, measured through PISA assessments in mathematics, reading, and science, explains cross-country differences in economic development. Using an unbalanced panel data set combining PISA results from 2015, 2018, and 2022 with macroeconomic indicators from the World Development Indicators, I estimate multiple regression models, including pooled OLS, country and time fixed effects, and subsample analyses for developed and developing countries. Results from the pooled model indicate strong positive associations between PISA scores and GDP per capita, consistent with human capital theory. However, these relationships diminish under fixed effects specifications, suggesting that cross-country …

Shrinkflation And Consumer Demand, Aljoscha Janssen, Johannes Kasinger
Research Collection School Of Economics
This study investigates shrinkflation—the practice of reducing product size while maintaining or slightly changing prices—in the U.S. retail grocery market. We analyze a decade of retail scanner data to assess the prevalence and patterns of product size changes across various product categories. Our findings show that approximately 1.92% of products have been downsized. When comparing total sales, product downsizing is more than five times as prevalent as upsizing. Product downsizing typically occurs without a corresponding decrease in price and is widespread across product categories. Consequently, consumers end up paying more per unit volume. We further find that consumers are more …

The Impact Of Sports Betting Legalization On Marital Status, Hosea Gitonga Njogu
Theses and Dissertations
This study examines the causal Impact of sports gambling legalization on marital stability in the United States using data from the Current Population Survey Annual Social and Economic Supplement (CPS-ASEC) and the American Community Survey (ACS) from 2013 to 2024. The analysis leverages variation in the staggered adoption of state-level sports gambling laws and applies two-way fixed effects, event-study, and the Callaway and Sant’Anna (2021) difference-in-differences estimators, controlling for geographic and individual characteristics. Legalization increases divorce rates by 0.42 percentage points in the CPS and 0.51 percentage points in the ACS, corresponding to increases of 2.4% and 2.6%, or approximately …

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: …
Exporting And Productivity: Evidence From Firm-Level Data In Tanzania,

Exporting And Productivity: Evidence From Firm-Level Data In Tanzania, Josephat J. Hongoli, Vincent Leyaro
Tanzanian Economic Review
Using firm-level data (2006 – 2023), this paper examines the interactions between export behavior and productivity among manufacturing firms in Tanzania. Specifically, the study tests the hypothesis that more productive firms self-select into export markets and benefit from global markets through learning-by-exporting and economies of scale. The study employs a two-step procedure to estimate firm-level productivity and compares exporting firms with non-exporting firms, controlling for observable heterogeneity. The findings of the study reveal a high and significant productivity premium of approximately 32 percent, which is consistent with the existing empirical literature. The results remain robust even when considering partial productivity …

Background: Global sustainability challenges and EU regulations, such as Directive 2014/95/EU, drive firms to adopt ESG practices, yet their financial impact remains debated. ESG initiatives are increasingly important for transparency, competitiveness, and alignment with the UN Sustainable Development Goals. In this context, green innovation emerges as a potential pathway to transform ESG commitments into tangible business value. Method: This study employed a regression model using the SPSS PROCESS macro (Model 4) with bootstrapping (95% CI) to analyze direct and indirect effects of ESG, green innovation, and financial performance in European energy, utilities, materials, and industrial sectors. Findings: The results …

Reading Between The Lines: The Influence Of Financial News On Investor Decision-Making, Kalia Noble
Honors College Theses
This thesis investigates how financial media narratives shape investor sentiment and short-term market behavior. Drawing on behavioral finance and narrative economics, it examines whether the framing and tone of market news correlate with intraday volatility in the S&P 500 and Dow Jones Industrial Average. By pairing quantitative price data with contemporaneous headlines from major outlets such as Bloomberg, Yahoo! Finance, and CNBC, the study shows that emotionally charged or speculative narratives are closely associated with sharp market swings, even when fundamentals remain unchanged. These findings highlight the influence of media framing on investor decision-making and underscore the importance of financial …

Housing Burden And Insurance Expenditures, Melanie M. Lytell
Honors Capstones
Housing costs shape the way families spend on protection and security. This study looks at how the share of income devoted to housing, the housing burden, influences household spending on four types of insurance: vehicle, life, personal, and health. Using data from nearly 92,000 households and regression models that account for state differences, I find that even small increases in housing burden shift insurance choices in meaningful ways. A one‑percentage‑point rise in housing burden is linked to a 2.1% increase in vehicle insurance spending and a 0.5% increase in life insurance, but a 0.7% decrease in personal insurance and a …

Investigating The Relationship Between Noun Classes And Plant Folk Taxonomy In Chasu Language Of Kilimanjaro Region In Tanzania, Peter Rabson Mziray
Journal of Humanities and Social Sciences
The current study investigates the relationship between noun classes and plant folk taxonomy in Chasu (G 22). The study focuses on two objectives: the first objective is to describe the plant folk taxonomy in Chasu and the second objective is to determine the relationship between noun classes and plant folk taxonomy in Chasu. Data were collected from rural villages in Same and Mwanga districts by using free listing, field interviews (jungle-walk-and-identify), and written texts containing Chasu plant names. The findings reveal that Chasu folk taxonomy reflects different ethnobotanical categories; including a unique beginner which is mmea/mimea ‘plant(s)’, and three life …

Learning About Stability Of Risk Preferences, Levon Barseghyan, Francesca Molinari, Joshua C. Teitelbaum
Georgetown Law Faculty Publications and Other Works
Classical theories posit that risk preferences are stable across decision contexts. Two branches of empirical literature assess this claim. Structural approaches examine within-person consistency of model-based estimates of risk aversion, while “model-free” approaches examine within-person correlations of risky choices. We elucidate the latent structure underlying the model-free approach. Using this structure, we develop a new approach to assessing preference stability that has stronger testable implications, and we partially identify features of stability and heterogeneity of risk preferences. Our study illustrates a general principle: partial identification through minimal assumptions grounded in economic theory robustly bridges fully structural and model-free methods.

Does Idiosyncratic Volatility Follow A Random-Walk? Evidence From U.S. Stocks, Zihan Cao, Ossama Elhadary
Publications and Research
In asset pricing literature, idiosyncratic volatility (IVOL) measures the firm-specific risk that is not explained by broader market movements. In this study, I investigate whether the idiosyncratic volatility (IVOL) of individual stocks follows a random-walk. Using monthly residuals from the Fama-French three-factor model (Fama & French, 1993), I estimate IVOL for more than 11,000 U.S. stocks, and apply the Augmented Dickey-Fuller test (Said & Dickey, 1984) to determine whether IVOL behaves like a random-walk. While most stocks display random-walk behavior, the proportion varies across industries, with some sectors showing deviations from random-walk behavior. Stocks with different levels of average return …

The Social Impact Of Unconditional Cash Transfer: A Quasi-Experimental Approach, Andar Ristabet Hesda
Bulletin of Monetary Economics and Banking
This study investigates the social effects of the unconditional cash transfer program and analyzes the underlying mechanism. The empirical analysis indicates that those who consistently participated as program beneficiaries own greater social capital than those who did not maintain continuous enrollment in the program. One mechanism of this impact is enhanced personality, particularly in social behavior. Furthermore, the characteristic of social capital most impacted is heightened participation in communal activities. This study indicates that the program neither displaces private aid nor promotes altruism. These data contradict the claim that the targeted cash transfer program could incite societal discord by fostering …

Financial stress does not just affect people’s finances; it can change the way individuals behave. This project asks whether short-term financial difficulty damages worker performance or if alleviating it improves focus and accuracy. Using data from a field experiment in rural India, this study examine how labor payment timing variability is related to workers' productivity and error rates. The study randomized payment dates across a sample of employees, so that employees paid early can be compared to employees paid on standard or later dates. It investigates whether subsidy of payments relieves stress and enhances task performance by minimizing stress, enhancing …

Journal of Human Sciences and Extension
The Stanford Center on Longevity reports life expectancy has surged over the last 120 years. Unfortunately, living longer may not equate to living with a higher quality of life without considering the amount, type, and uses of all resources available to individuals and families as they age. Family Resource Management (FRM) is the science and art of how individuals and families make decisions to develop and allocate resources, including money, time, energy, space, material, and health assets, and networks of support to meet their goals. Living longer means making more decisions and developing and allocating more resources to enhance the …

This study discusses the effects of assistance program with business digitalization features, on the income resilience and labor absorption of the assisted MSMEs, case study of DKI Jakarta’s JakPreneur Program. Observation data from 2017-2021 tested business resilience under time and economic crisis challenge, cause of pandemic. Treatment group is 31 respondents of JakPreneur members who had participated since 2017 or 2018. Control group is SAKERNAS data from 2017-2021. The result shows that treatment groups had lower incomes but were able to retain workers compared to control groups. Their low income is due to limitations in implementing business digitalization and accounting.
