Factors Correlated With State-Level Variation In Grocery Consumption Changes During The Covid-19 Pandemic, Sun Young Byun

CMC Senior Theses

In this paper, I employ a two-part empirical strategy to explore the effects of the COVID-19 pandemic on grocery consumption across U.S. states. First, I use the United States Department of Agriculture's Weekly Retail Food Sales data from 2018-2023 to estimate a time-series panel model. I use the results to test three hypotheses regarding state-level variation in consumption changes and impacts in the initial pandemic period, the remaining pandemic period, and the post-pandemic period. Second, I use the estimated state-level effects as dependent variables in cross-sectional regressions to test three hypotheses linking variation in state-level consumption patterns to economic, demographic, …

Keeping America Ahead: The Global Chip Conundrum, Ethan Chen

CMC Senior Theses

Semiconductors underpin nearly every aspect of modern economic, military, and technological power. Yet while the United States pioneered chip innovation and design, it now heavily depends on foreign manufacturing, particularly Taiwan and the Taiwanese Semiconductor Manufacturing Company who produce more than 90% of the world’s leading edge chips. This thesis investigates how the U.S. lost its fabrication leadership, what risks its current dependence creates, and what strategies can most effectively restore domestic capacity and resilience in both the short term and long term. By going through historical analysis of industrial development, recent policy evaluation such as export controls and the …

The Lipstick Effect Across Economic Crises: An Empirical Study Of Cosmetics And Luxury Spending From 2004 – 2023, Richard M. Sweeney Iii

CMC Senior Theses

This paper examines whether consumers shift toward lower-cost beauty products during periods of economic uncertainty and whether this behavior moves with financial market volatility. Using household-level microdata and aggregate monthly expenditure data from the Bureau of Labor Statistics’ Consumer Expenditure Surveys (2004–2023), the study evaluates how cosmetics spending changes relative to jewelry across two major economic crises: the Global Financial Crisis and the COVID-19 pandemic. Across both datasets, cosmetics consistently become a larger share of discretionary spending when economic conditions deteriorate, supporting the presence of a lipstick-effect pattern. At the macro level, cosmetics spending is generally inversely related to market …

Maternity Leave And Women’S Leadership In A Changing Work Environment: Global Evidence, Josefine Byström

CMC Senior Theses

Family leave policies play a central role in shaping women’s participation and advancement in the labor market. This study investigates whether the relationship between maternity leave duration and women’s labor outcomes has changed before and after the COVID-19 pandemic. Using a cross-country panel spanning multiple years with fixed effects, this study examines two related outcomes: women’s labor force participation and representation in leadership. Prior to 2011, maternity leave duration displayed opposite non-linear patterns across these outcomes: an inverted U-shape for labor force participation, peaking at moderate leave lengths, and a U-shape for women’s leadership, which improved only at longer durations …

The Politics Of Russian Regional Development, Claire Moore

CMC Senior Theses

This thesis examines why Chechnya’s independence movement shifted from a secular nationalist struggle in the First Chechen War (1994–1996) to a religiously framed insurgency in the interwar period and Second Chechen War (1999–2000; 2007). Drawing on presidential speeches, interviews, archival materials, and secondary scholarship, it argues that religious radicalization cannot be explained solely by external influence or Russian military brutality. Instead, three underexplored variables–strategic economic appeals to the Islamic world, culturally-embedded practices of vengeance, and the enabling conditions of poverty and mass armament–collectively shaped this transformation. Chechen leaders increasingly emphasized Islamic identity to secure financial and military support from Middle …

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 …

From Static Λ To Moving Penalties: Dynamic Regularization In Mean-Variance Portfolio Choice, Ariel Santiago

CMC Senior Theses

This thesis evaluates whether dynamically tuned weight penalties can improve high-dimensional mean-variance portfolio choice. Classical Markowitz portfolios perform poorly when the number of assets is large relative to the data, because small estimation errors in means and covariances can generate extreme, fragile allocations. A common remedy is to regularize the weights using L1 (lasso), L2 (ridge), or elastic-net penalties, but these are typically chosen once and held fixed. Using monthly excess returns on the 48 Fama-French industry portfolios from January 2010 to June 2025, this thesis compares penalized mean-variance and minimum-variance strategies under long-only and long-short constraints, with and without …

Esg And Misvaluation In U.S. Equity Markets, Rohaan Bhojwani

CMC Senior Theses

Existing research has produced conflicting conclusions on whether environmental, social, and governance (ESG) characteristics are efficiently priced in equity markets. While some studies argue that ESG performance improves firm value through lower risk and stronger fundamentals, others suggest that investor demand has inflated valuations in the past beyond intrinsic worth. This thesis examines whether ESG-driven valuation gaps represent justified pricing through firm fundamentals or systematic mispricing using Bartram and Grinblatt’s Agnostic Fundamental Analysis Framework (2018).

For this paper, I analyze the top 1000 U.S public firms by market value. I regress the market value on 19 accounting fundamentals for these …

Magang Atau Pekerja? Menggugat Status Abu-Abu Tenaga Paruh Waktu Mahasiswa Di Fakultas Hukum Ugm, Patricia Nerissa Krisna Putri, Markus Togar Wijaya

Jurnal Hukum & Pembangunan

This study highlights the controversy surrounding the change in nomenclature for student workers at Gadjah Mada University, particularly within the Faculty of Law. The status of these workers has shifted from 'part-time' to 'student intern'. This unilateral change has created a legal grey area that could lead to students being subjected to disguised employment practices. Using socio-legal research methods, this article examines the validity of the 'internship' status based on the elements of an employment relationship (work, orders and wages) within the labour law regime, analysing it using the theory of structural injustice. The research findings suggest that reclassifying part-time …

The Steelerville Case: Applying Criminological Theory To Crime And Police Morale, Shamus Smith

Open Educational Resources

Students use a fictional town’s economic decline and rising crime to evaluate at least two criminological theories and their implications for policy. Role-playing as consultants, they develop research-supported recommendations to reduce crime and improve police morale.

Mapping Robusta Coffee (Coffea Canephora) Cropping Systems In Uganda: A Two-Step Pixel And Sub-Pixel Based Approach With Sentinel-2 Data, Getachew Kebede, Bester Tawona Mudereri, Onisimo Mutanga, Tobias Landmann, John Odindi, Natacha Motisi, Fabrice Pinard, Henri E.Z. Tonnang, Elfatih M. Abdel-Rahman

All Peer-Reviewed Publications

Coffee is a highly valued commodity and a widely consumed beverage, playing an important role in global trade. However, coffee farming landscapes are increasing transitioning into smaller-scale agricultural setups. This transformation highlights the critical need for accurate classification and mapping of coffee cropping systems (CS), especially in countries like Uganda, where dense vegetation and complex terrain present substantial challenges to traditional land survey methods. Moreover, understanding the spatial distribution of Robusta coffee (Coffea canephora) CS is essential for developing site-specific management strategies, guiding extension services, and informing evidence-based policy decisions. To address this gap, the present study aimed to enhance …
