The Ecological Impacts Of Un-Protecting Forests: The Case Of Gold Mining In Ghana, Tate Alexander Barend

Master's Theses

This paper estimates the causal effect of Ghana’s Legislative Instrument 2462 (L.I. 2462) on deforestation in protected areas. The policy redefined the regulatory regime governing small-scale gold mining in protected areas, moving from prohibition to discretionary permitting. I exploit the implementation of L.I. 2462 as a policy shock and apply a difference-in-differences event-study framework to a propensity score–matched sample of pixels derived from high-resolution satellite images. Contrary to widespread concerns that the policy would accelerate deforestation, the results provide no evidence of large-scale vegetation loss in exposed protected areas following the policy change. Instead, protected area pixels located within 5 …

Crop Yield Shocks And Conflict In Sub-Saharan Africa: Subnational Evidence From Satellite-Based Yield Predictions, Benson I. Adomako

Master's Theses

This paper examines whether crop yields affect violent conflict at the subnational level across seven Sub-Saharan African countries: Burkina Faso, Ethiopia, Mali, Malawi, Niger, Nigeria, and Tanzania, over the period 2010 to 2024. A central identification challenge is that observed yields are endogenous to conflict: armed violence disrupts planting, cultivation, and harvest. To address this, I train a machine learning model on observed maize yield and satellite and environmental features to generate predicted yields for 1,338 second-level administrative districts annually. These predictions serve as the key regressor in a two-way fixed-effects panel with district and year fixed effects. I find …

Spatial Analysis Of Maize Yields And Household Dietary Diversity In Sub-Saharan Africa: Causal Evidence From A Machine Learning Instrument, Addi Joof

Master's Theses

MAIZE YIELDS AND HOUSEHOLD DIETARY DIVERSITY IN SUB-SAHARAN AFRICA: EVIDENCE ON THE CAUSAL EFFECT FROM A MACHINE LEARNING INSTRUMENT

Addi Joof, University of San Francisco, May 2026

This paper provides estimates of the effect of maize yield on household dietary diversity across seven Sub-Saharan African countries, using data from 36,474 maize-growing households in the Living Standards Measurement Study Integrated Surveys on Agriculture (LSMS-ISA) panels for the period 2008--2021. OLS estimates which include district and country-by-wave fixed effects yield a positive and significant coefficient of 0.070 (SE = 0.006, p < 0.001), implying that a 10 percent increase in maize yield raises the Household Dietary Diversity Score (HDDS) by approximately 0.007 food groups. Because self-reported yields are subject to classical measurement error and unobserved household characteristics confound the OLS estimate, we construct an instrumental variable using a Random Forest model trained on satellite-derived agro-environmental features including the Enhanced Vegetation Index, Normalized Difference Vegetation Index, Growing Degree Days, precipitation, and soil moisture obtained from Google Earth Engine at the GPS-coordinate-by-year level. Our preferred 2SLS specification, which adds region fixed effects to absorb persistent sub-national geographic variation, returns a positive point estimate of 0.217 (SE = 0.206; 95% CI: -0.19 to +0.63, p = 0.294) larger than OLS and consistent with downward attenuation bias, but imprecisely estimated and statistically indistinguishable from zero at conventional levels. We interpret the OLS estimate of 0.070 as a credible lower bound on the true effect, with the IV evidence pointing to a moderately larger but uncertain magnitude. Heterogeneity analysis reveals a declining gradient across consumption quintiles the effect is strongest among the poorest households (Q1: 0.055, p < 0.01) and diminishes with wealth (Q5: 0.015, not significant) while showing no gradient across market-integration levels. These patterns are consistent with own-consumption, rather than market income from surplus sales, as the primary pathway from yield to dietary diversity. OLS estimates are positive and significant in five of six estimable countries. The findings suggest that maize yield improvements can serve as a nutrition co-investment, particularly for subsistence-oriented smallholders, though the available data do not permit a sharp causal quantification of the effect size.

Mitigating Agricultural Income Volatility: Evidence From Crop Insurance Adoption In India, Annoushqa Bobde

Master's Theses

Income volatility resulting from crop loss presents a significant threat to rural livelihoods in India, where nearly half of the workforce is employed in agriculture. This study examines the causal impact of crop insurance uptake on farm income using nationally representative data from the 70th and 77th rounds of the National Sample Survey, merged with satellite-derived climate data and Harmful Degree Days (HDD), which is used as a proxy for crop-damaging temperature. To address selection bias in insurance enrollment, Propensity Score Matching, Inverse Propensity Weighting, and a Two-Way Fixed Effects model are used. Results show that insurance uptake is associated …

The Long-Term Effect Of Universities On Local Technology, Dafina Rizvanolli

Master's Theses

This paper studies the long-term effects of universities on local economic complexity, contributing to new evidence on how higher education institutions shape local productive capabilities over time. While extensive research documents universities’ positive impact on development, fundamental questions remain about the mechanisms through which they operate. Our study employs the Economic Complexity Index (ECI), a measure that captures the diversity and ubiquity of regional economic structures, to provide novel insights into universities’ influence on local economies. Building on Andrews (2023), we exploit historical natural experiments in university site selection during the 19^th and 20^th centuries in the U.S. …

The Hidden Logic Behind Migration And Success, Elsa Russom

Master's Projects and Capstones

This research paper explores the hidden drivers of financial success among Eritrean migrants navigating uncertainty, displacement, and limited institutional access. Drawing on original survey data collected from diaspora communities across East African host countries, I apply a mixed-methods framework combining ordinal and binary logistic regression, random forest classification, bootstrapping, and Bayesian causal mediation; to identify the structural and cultural variables most predictive of financial stability. The findings reveal that participation in Ekub, a traditional rotating savings association, and engagement in communal support systems are the strongest predictors of financial success, outperforming conventional factors such as age, education, or employment status. …

What Gives? Trust, Risk, Altruism, And Reciprocity Across 76 Countries, Sherwin Mosavat

Master's Theses

Abstract:

The decades-long literature pertaining to gender-specific preferences lies at the intersection of economics and psychology with a primary focus on the correlation between economic development and gender-specific preferences. Better understanding of this correlation has helped researchers understand how individuals make decisions for their education, finances, and occupation. Falk & Hermle (2018) assess the correlation between GDP and various gender-specific preferences including trust, risk, altruism, and reciprocity. In order to better understand the relationship between economic development and gender-specific preferences, I expand on the Falk & Hermle 2018 framework by introducing new macroeconomic, prosocial, and cultural variables as additional explanatory …

To Burn Or Not To Burn: Causal Effect Of Farm Stubble Burning On Air Quality., Chaitanya Pasupala

Master's Theses

National Capital Region of India (NCR) experiences adverse air quality during winters with Air Quality Index (AQI) at hazardous levels. Though various factors like industrial and automobile emissions, biomass burning, and firecrackers during festive season contribute to NCR’s adverse air quality, farm stubble burning in neighbouring agricultural regions of Punjab and Haryana is considered a prominent one. The motivation and consequences of farm-stubble burning in Punjab and Haryana have been extensively studied but the causal effect of this burning on air quality of Delhi has neither been rigorously analyzed nor the effects quantified. This study aims to bridge this gap …

Exploring The Relationship Between Load Shedding And Crime In Gauteng, Bhavesh Ram

Master's Theses

This study investigates the impact of load shedding, a recurring power outage phenomenon in South Africa, on crime rates in the densely populated Gauteng province. Using a novel dataset that combines Eskom's load shedding schedules with detailed crime statistics from 2015 to 2022, a fixed-effects regression model is employed to examine the relationship between blackout hours and various crime categories. Findings reveal that while load shedding does not significantly affect overall crime rates, it significantly increases the incidence of contact crimes and sexual offenses, particularly during daylight hours. Additionally, our results provide evidence that load shedding diminishes the ability of …

Impact Of Temperature On Children’S Nutrition: A Comparative Study Of Three Ecological Regions Of Nepal, Prakriti Shakya

Master's Theses

Nutrition obtained during the growth period of childhood significantly influences long-term well-being and overall productivity, ultimately contributing to the economy of a society. However, weather shocks can wreak havoc by damaging crops, changing yields of important crops and disrupting market access, which directly impacts the food intake of both adults and children. When these adverse events occur during childhood, short term and long term inadequacy in nutrition as well as disease incidence can cause malnutrition leading to stunted growth and cognitive impairment that may persist into adulthood, affecting the labor market and increasing health expenditure. To address this issue, we …

The Impact Of Female Political Leadership On Intimate Partner Violence In India, Khushboo Patel

Master's Theses

Abstract:

This study employs an instrumental variable approach to examine the impact of female political leadership on women’s experiences of Intimate Partner Violence (IPV). It finds that in rural areas with more female leaders, incidents of sexual and psychological IPV increase. The analysis investigates the drivers behind this impact, revealing that entrenched gender norms and expectations, such as a husband’s preference for more sons, may exacerbate IPV. Additionally, despite the increase in female leaders, attitudes toward violence remain largely unchanged. These findings highlight the need for research and policy initiatives that not only encourage female political participation but also specifically …

The Impact Of Refractive Error Correction On Harvest Productivity In The Guatemalan Coffee Sector, Bryce C. Everett

Master's Theses

Providing refractive error correction has the potential to bolster productivity within developing countries. Current literature is in agreement that interventions targeting those with uncorrected visual impairment can realize benefits in various sectors, with particular regard to agriculture. The design of this experiment attempts to derive the intent-to-treat (ITT) effect stemming from the provision of glasses to coffee harvesters in Guatemala. Methodology incorporates two distinct approaches: an ANCOVA model with basic controls and a fixed effects model with a control for farm-specific harvest trends. With daily harvest weight observations serving as a proxy for productivity, and a sample of 321 participants …

The Impact Of Index Based Livestock Insurance (Ibli) On Child Nutrition In Marsabit County, Kenya, Jackson Kadyampakeni

Master's Theses

The study uses six rounds of Index-Based Livestock Insurance (IBLI) panel surveys (2009 – 2015) for Northern Kenya’s Marsabit county to investigate the impact of IBLI on child nutrition and household food security. We employ Ordinary Least Squares (OLS) and Instrumental Variable (IV) regressions to account for potential endogeneity in IBLI uptake. The results indicate that while IBLI uptake significantly improves the intake of key nutrients such as Vitamin A, protein, iron, and fruits and vegetables, it does not translate into significant improvements in child nutrition status, as measured by Mid-Upper Arm Circumference (MUAC) z-scores. Significant negative effects of age …

What The Stork Brought: Endogenous Fertility Preferences, Lucas Fortier Borden

Master's Theses

Where most existing literature on fertility preferences has described how fertility preferences shape outcomes, this paper provides insight into how the sex of a recent birth affects a mother’s fertility preferences. Utilizing data from the Demographic Health Survey from 1985-2020 in 81 countries containing 309,238 mothers who gave birth in the past 12 months and who have equal to or fewer than three children, I employ OLS with two-way fixed effects as my primary specification, examining the effects of the plausibly exogenous sex of a recent birth on sibship sex composition preferences. Results show that a recent daughter birth increases …

Leveling Up Financial Literacy: Evidence From Game-Based Intervention With Aspiration Treatment Amongst Rural Women In India, Akash Shaji

Master's Theses

In India, rural women exhibit notably low financial literacy levels, necessitating effective and scalable educational interventions. Our randomized controlled trial evaluated a novel approach, combining game-based financial literacy education with a video documentary-based aspirations intervention, targeting women in self-help groups in Karnataka. The study included 348 participants and employed an ANCOVA model adjusted for clustering to analyze the effects. The results demonstrate significant improvements in financial literacy and aspirations, particularly when interventions are combined. The game-based intervention alone significantly enhanced digital literacy, financial confidence, and behavioral indices such as agency, pathways, and aspirations. The aspirations intervention also independently affected financial …

Matrilineal Ethnic Affiliation And Female Empowerment: Investigating Attitudes Towards Female Autonomy And Health In Ivorian Households, Martine Hind Stølan

Master's Theses

Kinship structure is a fundamental aspect of anthropology, however, there is still a gap in literature on its impact on economic research, particularly regarding female autonomy and health. This study aims to address this gap by examining the influence of matrilineal ethnic affiliation on attitudes towards female autonomy and health within Ivorian households. Using data from the 2011 IPUMS Demographic and Health Survey for the Ivory Coast, using female responses, this study investigates the complex dynamics shaping attitudes towards female autonomy and access to health care. Analysis on these aspects is done using ordinary least squares (OLS) and logistic estimations. …

Assessing The Economic Consequences Of Sewage Overflows On California Housing Values, Nathalie M. Nyanga

Master's Projects and Capstones

Sewage overflows (SSOs) represent a critical environmental challenge in California, and the impact of SSOs on housing prices is a vital issue. The study aims to determine how the frequency of sewage overflow events affects housing price fluctuations and conduct an event study. Employing linear, lasso, ridge, and random forest regression analyses, the study predicts the severity of overflow. Notably, lasso regression emerges as the most effective model for predicting housing prices in the event of an SSO occurrence. Additionally, the event study analysis provides insights into the factors influencing housing prices.

Heat & Social Cooperation: The Effects Of Thermal Stress On Altruism, Alexander J. Courtman

Master's Theses

Recent literature has highlighted the effects of temperature on economic outcomes and violence in humans, on both the interpersonal and intergroup levels: as temperatures rise, humans are more likely to exhibit increased aggression and agitation. However, little research has been done on how pro-social behaviors like cooperation and altruism among humans might respond to increased temperatures. As extreme heat events increase in frequency, will humans and communities work together in the face of adverse shocks and crises? Leveraging experimental data collected randomized controlled trails held in 4 locations across the world, this paper seeks to establish a relationship between thermal …

Climate & Conflict: View Into A Warming World, Faelynn Carroll

Master's Theses

Unlike weather patterns, the El Niño Southern Oscillation (ENSO) is a large-scale, cyclical climate system that is now predictable for up to a year and a half in advance. ENSO cycles occur every two to seven years for approximately two years at a time, affecting large swaths of the globe with plausibly random variation in the exact location and strength of local effects. However, its systemic nature allows for aggregate effects to be accounted for by its outcomes. This research uses novel 0.5 x 0.5 degree ENSO teleconnection analysis for precipitation and temperature to uncover environmental mechanisms that underly the …

Tempers Rising: The Effect Of Heat On Spite, Jake C. Cosgrove

Master's Theses

The relationship between heat and harmful outcomes is well documented, with research connecting various adverse economic outcomes to the climate. In the presence of increasing global warming and climate change, understanding why the climate leads to negative economic outcomes is essential for forming peaceful institutions of the future. We study how behavioral economic outcomes change in the presence of heat through a lab experiment involving 1,110 observations conducted in five different countries. This paper specifically focuses on the social preference outcome of spite. We find that increased time exposure to the treatment effect of heat is required to elicit an …

Charity Begins At Home: Investigating How Culture Shapes In-Group Bias In Altruistic Behavior, Angira Shukla

Master's Theses

The paper builds a structural model of altruistic transfers based on identity matches with another individual and estimates the weights that people place on the characteristic matches. We also take a comparative look at the role of culture in these transfers. The culture here is trying to contrast a traditional society versus a cosmopolitan one. I run an experiment in India to examine these differences. I find that in both the urban and rural samples individuals tend to give more to girls and donate largely on the basis of the need of the receiver. I also find that the rural …

Charcoal, Droughts, And Deforestation: Evidence From Mozambique, Kaitlin N. Paull

Master's Theses

Mozambique is prone to harsh weather conditions due to its geographic location, and these conditions are expected to worsen in the face of ongoing climate change. Many of Mozambique’s farmers rely on rain-fed agriculture, meaning their livelihoods are highly vulnerable to worsening weather trends. Some farmers have diversified their incomes with charcoal production, making use of Mozambique’s abundant forest resources. This study measures how reliance on charcoal as an income diversification strategy affects forest loss, and found inconclusive effects of rainfall on deforestation. However, the study does find that a one-unit increase in hot degree days increases the probability of …

Feeling The Heat: Heterogeneous Treatment Effects Of Heat On Human Cooperation, Scott K. Klaus

Master's Theses

The goal of this paper is to examine how increased temperatures affect human behavior in terms of cooperation. Currently, there is an abundance of literature regarding increased aggression in humans as temperatures rise. However, there is ambiguity concerning whether a similar effect exists in altering levels of cooperation in human interactions. Additionally, people of different characteristics may be influenced by heat at varying levels. First, we run a baseline model of prosociality on different heat measurements, such as standard and wet-bulb temperatures. Included in this model are experimental specification variables, a “trigger”, and characteristics. The trigger is defined as losing …

Sweet And Timely Insurance: The Role Of Honey In Reducing Coffee Producer Food Insecurity Exposure In Mexico, Grant Xavier Storer

Master's Theses

Smallholder coffee producers face a combination of pre- and post-harvest risk factors that leaves them particularly vulnerable to food insecurity. A popular form of on-farm diversification is honey production through beekeeping, that has both nutritional and commercial value. This study investigates the role of honey production as means of food security management due to the heightened pollinating activity during the coffee flowering stage that follows the annual coffee harvest provides an additional non-contemporaneous source of income. Using primary data collected in coffee-producing regions of Chiapas, Mexico, I find that during the honey harvest months, which occurs during the early stage …

Impacts Of Rising Temperatures On Human Behavior With A Focus On Gender Differences, Stephanie Marie Emilia J. Hermoso

Master's Theses

Climate change is one of the biggest and most pressing issues the world is facing today. While its economic implications are substantial, it is also important to investigate the effects of climate change on human behavior. This paper examines the relationship of rising temperatures and its effect on an individual’s cooperative behavior – specifically egalitarianism, generosity, selfishness, and spite. This study will focus on the differences between how males and females react to the temperature. Research indicates that there are substantial behavioral differences between men and women. How do the economic decisions of men and women differ when interacted with …

Early Life Exposure To Enso And Adult Human Capital, Ashley J. Stewart

Master's Theses

Do El Niño Southern Oscillation conditions during a woman's early childhood lead to negative health outcomes in adulthood? This study poses as an extension of the 2021 paper by Anttila-Hughes et al. titled “ENSO impacts child undernutrition in the global tropics” and utilizes data from the same DHS, UDEL temperature and precipitation, and NOAA Center for Weather and Climate Prediction datasets. It proposes to investigate whether the undernutrition effects found in children persist into adulthood by measuring the effects on their mothers and the intergenerational effects on their offspring. Results indicate that a 1℃ increase in sea surface temperatures in …

Heating Systems And Households’ Expenditure, Svitlana Holyk

Master's Theses

The heating energy expenditure has been frequently taken to the consideration across different studies of poverty reduction. However, there is an unresolved question related to understanding how households’ expenditures might be distinct due to the heating system characteristics. This research implements matching methods to investigate the causal effect of the heating system on households’ gas and electricity expenditure in Ukraine. The result indicates that there is a significant difference in the utility expenditure between the District heating system (DHS) and the Individual heating system (IHS) households. The inherited from the past the Soviet District heating system Model in Ukraine doesn’t …

Does My Skin Tone Really Matter? A Socioeconomic Analysis In Nigeria., Mutiu O. Fakorede

Master's Theses

Abstract: Does my skin tone really matter? If it does, to what extent and direction does skin tone predict socioeconomic outcomes, especially amongst people of color who have experienced colonial rule with its white supremacy agenda? In this research, we examined if skin tone measured in individual typology angle (ITA) does not affect employability, income, partner selection, and political representativeness. With a focus on Nigeria, the most populous black nation, a former British colony, we addressed this broad question through a survey. Using the iterative capability of Qualtrics which randomly picks a set of three pictures with known ITA and …

Do Conditional Cash Transfers Increase School Enrollment? Evidence From Brazil, Jeanette L. Silvernale

Master's Theses

Conditional cash transfer programs have been widely deployed across the globe. They seek to bolster human capital by providing benefits contingent upon a variety of actions such as school attendance and regular health checkups. Bolsa Familia is the most extensive conditional cash transfer program, serving 46 million Brazilian citizens. Despite its expansive size, there have been seldom large-scale micro evaluations of the program. Limited data has resulted in small sample sizes drawn from a single point in time. Our study diverges from the rest and utilizes a novel administrative dataset with an overall sample of nearly 60 million and a …

The Health Costs Of Political Identity: Evidence From Public Safety Responses In The Us And A Natural Experiment In California, Sahiba Chopra

Master's Theses

The Covid-19 pandemic has brought political polarization in the US to the forefront of the battle against coronavirus. We find that for every one percentage point increase in votes for Trump there are 881 more Covid-19 cases and 17 more Covid-19 deaths. We find that these results are motivated by political identity as it is mediated through public safety behaviors like maskwearing and social distancing. In addition, a natural experiment in California during the first half of the pandemic in the US finds that 36% of the Covid-19 cases at the census tract level in California can be associated with …
