Trust and trustworthiness are integral components of cooperation: a behaviour which drives economic growth and prosperity. However, the levels of such vary dramatically across the world. Drivers of trust heterogeneity include institutions, socioeconomics and cultural norms. In this experiment, I investigate intra- and inter-cultural trust levels across the so-called North-South divide in England using a risk-adjusted trust game. The setting is of high policy relevance due to the national government’s increasing focus and investment in spreading economic opportunity across the country. In reproducing results from the World Value Survey, I aim to decompose the trust differential into socioeconomic factors and belief asymmetries across the divide. I then study how specific trust differs ac...
We will evaluate the importance of women's economic development for their empowerment at the individual, household and community levels. For this purpose, we will evaluate a multifaceted programme which provides a conditional loan, free assets and training to ultra-poor women for their economic development. This programme helps women to engage in economic activities which might increase their empowerment at different levels. To test this hypothesis, we will estimate the impacts of this programme on women empowerment using a randomized control trial with three waves of surveys. A baseline and an endline surveys were conducted in 2016 and 2019, respectively and these surveys collected data on women empowerment, particularly, women's risk-aversion, patience, participation in intra-househol...
In Bangladesh, half of girls aged 20-24 were still married before the age of 18, according to the most recent national survey (Bangladesh Bureau of Statistics (BBS) and UNICEF, Bangladesh, 2019). Parents face strong social and economic pressures to marry their daughters early%, including financial needs and dowry obligations, limited availability of desirable grooms, fear of elopement, lower demand for older girls, an concerns about girls' safety. One aspect that has received limited attention is the girl's safety. While the security provided by a groom can be an important motivation for marriage, most people seem unaware that early marriage substantially increases the risk of intimate partner violence - that is, violence perpetrated by the future husband%, directly or indirectly thr...
Take-up of safety net programs in the United States remains incomplete, even among individuals who are already enrolled in other public benefits. In Connecticut, a substantial share of Medicaid beneficiaries are likely eligible for Supplemental Nutrition Assistance Program (SNAP) benefits, but do not participate, representing a missed opportunity to improve household well-being and potentially reduce downstream health care costs. This study will investigate whether low-cost, scalable outreach can increase SNAP enrollment among Medicaid beneficiaries in Connecticut, and whether providing access to application assistance is more effective than providing eligibility information alone. We will pilot a SNAP enrollment randomized controlled trial among a sample of 250,000 households e...
Climate change-induced salinization (CCIS) poses a significant public health threat in low-elevation coastal zones like Bangladesh, degrading drinking water quality and contributing to adverse outcomes, including hypertension and reduced productivity. While these risks are increasingly documented, critical evidence gaps persist regarding effective, scalable interventions that foster the sustained adoption of safe water alternatives, particularly given behavioural barriers such as cost sensitivity and taste acclimatization. This project aims to fill this gap through a cluster randomized controlled trial (cRCT) in Khulna, Bangladesh, an area severely impacted by CCIS. We propose to experimentally evaluate an innovative intervention that combines subsidies for desalinated water with target...
Workplaces are gendered. Women tend to work with 70% female colleagues, while men work with only 30% female colleagues. This significant gender segregation in the workplace is linked to the gender wage gap. A large body of literature also indicates that people tend to associate with others of the same gender, a tendency known as 'Gender Homophily.' This homophily may further contribute to gender segregation in the labor market, as it suggests a desire to interact with same-gender coworkers. We test this hypothesis in a lab experiment in which we allow participants to sort into teams endogenously. First, we measure gender homophily by studying whether women choose to team up with women, and men with men. Second, we delve further into the mechanisms behind gender homophily by introdu...
This study tests whether (a) providing residents with an informational door‑hanger about the City of San Diego’s 311 “Get‑It‑Done” (GID) system and (b) recent visible service delivery (a recent pothole repair on a resident’s street) change knowledge, attitudes, and City services requesting behavior. We will randomize street segments to receive door‑hangers and conduct door‑to‑door surveys on a weekly basis. The study population is City‑maintained residential street segments, focusing on single‑family homes, with coverage across all nine Council Districts over the course of about seven months. Primary outcomes are survey measures (GID knowledge and perceptions) and administrative behaviors (subsequent GID requests). Analyses compare door‑hanger vs control and recent‑fix segments vs unfix...
When interacting with others, individuals are uncertain about whether they will encounter pro-social or anti-social behavior. In such interactions, even a single observation can trigger biased beliefs about entire groups. We conduct a laboratory experiment in which participants simultaneously receive statistically irrelevant information about their in-group and out-group, with treatments varying whether both signals are pro-social or anti-social. Since the informational structure is identical across groups by design, any subsequent difference in cooperative behavior toward in-group versus out-group members must reflect asymmetric biased beliefs. We hypothesize that individuals overweigh signals that confirm existing group stereotypes, generalizing negative information about out-group me...
A growing body of evidence demonstrates the crucial importance of access to quality childcare services for child development, women’s economic opportunities, and by extension the wellbeing of families and communities (Aliga et al., 2023). Early childhood care has a central role in fostering children’s physical, intellectual and psychosocial development, with effects experienced along the life course (Black et al., 2017). As women fulfill most care responsibilities across societies, access to childcare services also has transformative potential for women’s engagement with the labor market (Evans, Jakiela and Knauer, 2021). The effects of interventions focused on early childhood care on children and mothers have been well documented across higher-income country settings (Del Boca, 2015...
Combating the overdose epidemic is a central challenge of US health care policy. The most effective treatment for opioid use disorder is medication assisted treatment (MAT), but barriers to access lead more than eighty percent of those in need of MAT not to utilize it. Providers are increasingly exploring the use of vans to provide mobile opioid outreach and MAT to communities where traditional brick-and-mortar provision is costly or otherwise challenging. However, there is no empirical evidence on the impacts of mobile opioid outreach and treatment (MOOT). In light of this, Pierce County Human Services (PCHS) has committed to randomizing the locations of two funded MOOT vans scheduled to be deployed in 2026-27---and hopefully beyond---serving approximately 300 opioid users per year....
