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 …

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 …

How Esg Performance Influences Financial Performance In Europe: Unpacking The Mediation Effect Of Green Innovation, Esa Panganti Widoretno, Anawinta Choirunnisa, Mirza Aulia Nur Fajri

Jurnal Akuntansi dan Keuangan Indonesia

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 …

Do Financial Concerns Make Workers Less Productive?, Dua Khowaja

2025 Fall Honors Capstones Projects - Archive

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 …

Aging In America: Implications For Family Resource Management, Becky Smith, Portia Johnson, Brandan Wheeler, D E Kiss, Ann A. Berry

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 …

Efek Program Pendampingan Umkm Terhadap Performa Ketahanan Pendapatan Dan Penyerapan Tenaga Kerja Umkm : Studi Kasus Program Jakpreneur Dki Jakarta, Farah Khoirur Fadhila, Muhammad Hanri

Jurnal Kebijakan Ekonomi

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.

Revisiting Kin And Ethnic Favoritism In The Bribery Experiment, Mahsa Akbari, Duman Bahrami-Rad, Erik O. Kimbrough

Economics Faculty Articles and Research

We report a conceptual replication of Akbari et al. (2020), who study the impact of co-ethnicity and kinship on behavior in an experimental “bribery game”. In the game, player A can offer a bribe to B, who can help A by inefficiently transferring resources from passive third-party C. We replicate the finding that by varying the relatedness of A, B and C, we can substantially modulate the willingness of A to offer the bribe and the willingness of B to reciprocate the bribe by harming C. The findings are consistent with theories of kin altruism and ethnic favoritism.

Sociohydrodynamics: Data-Driven Modeling Of Social Behavior, Daniel S. Seara, Jonathan Colen, Michel Fruchart, Yael Avni, David G. Martin, Vincenzo Vitelli

Data Science Faculty Publications

Living systems display complex behaviors driven by physical forces as well as decision-making. Hydrodynamic theories hold promise for simplified universal descriptions of socially generated collective behaviors. However, the construction of such theories is often divorced from the data they should describe. Here, we develop and apply a data-driven pipeline that links micromotives to macrobehavior by augmenting hydrodynamics with individual preferences that guide motion. We illustrate this pipeline on a case study of residential dynamics in the United States, for which census and sociological data are available. Guided by Census data, sociological surveys, and neural network analysis, we systematically assess standard …

Essays In Applied Microeconomics, William Cunningham

Economics Theses and Dissertations

This dissertation contributes to three interconnected areas of economic research: microeconomics, behavioral economics, and urban economics. Each chapter examines how individual decision-making processes may produce more pronounced economic patterns, while highlighting the role of psychological factors and spatial considerations in shaping outcomes. Chapter 1 studies the causes and dynamics of segregation in US neighborhoods. A conditional instrumental variables estimator allows for unbiased estimation of preferences for past neighborhood minority shares by addressing endogeneity concerns present in my theoretical model. I use estimated preference parameters to simulate neighborhood population dynamics for Texas. I regress measures of racial animus and xenophobia on …

Criminal Behavior Responses To Changing Penalties: Estimating The Impact Of Felony Theft Threshold Changes, Ezra R. Simmons

All Theses

This study estimates how criminal behavior changes in response to shifts in felony theft thresholds, contributing to broader evidence on the deterrent effects of criminal penalties. Using detailed incident-level crime reports, this study applies econometric techniques to evaluate how offenders responded to reduced penalties. Analyzed within is California’s Proposition 47, which raised the felony threshold for theft-related offenses from $450 to $950. The results show a significant increase in low-level shoplifting (approximately 21%) and more substantial rises (approximately 24% to 30%) in crimes within the threshold overlap ($450 to $950). Additionally, the value stolen in crimes below the $450 threshold …

Decision Field Theory For Human-Multi-Robot Collaboration: Human-Centric Decision-Making For Multi-Robot Systems, Ryan Mbagna Nanko

All Theses

At first glance, choosing between an apple and an orange appears to be a straightforward matter of personal taste; however, this seemingly simple preference opens a window into the multifaceted world of decision-making, revealing the complex interplay of cognitive processes, psychological, and behavioral-economic principles that guide our choices \cite{bandyopadhyayRoleAffectDecision2013}. By unpacking these nuanced perspectives, we uncover insights that can drive more effective human-robot interaction and collaboration.

Modeling human cognition requires understanding the evolution of choice utility and the influence of emotions. Decision Field Theory (DFT) stands out by capturing the fluctuating nature in human preferences over time, explaining why choices …
