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...
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....
We study what respondents in Denmark know and think about the functioning of the public pension system. Thanks to the match of survey responses to administrative data from Statistics Denmark, we can test whether respondents have accurate information about their own pension situation. We randomly provide a subset of respondents with information about their pension rights and features of the pension system, with a focus on fiscal sustainability, redistribution within and across generations, or pocketbook motives. We then study how information on these dimensions changes respondents’ views on pension policy and the role of government, and their stated political behavior. In a parallel, non-experimental component, we exploit quasi-random variation in individuals' normal retirement age ge...
This research studies how monetary penalties for inaccurate responses affect participants’ reliance on AI-generated recommendations. Participants complete a series of CAPTCHA-style object-counting tasks, with and without access to a pre-generated recommendation from an AI agent. The experiment permits within-participant comparisons of task attempts and accuracy across AI-available and AI-unavailable conditions. Participants are paid a piece-rate reward for each correctly completed task and are assigned to one of three treatment levels that differ in the penalty for incorrect responses. To study differences in AI reliance across participants, we elicit participants’ beliefs about the accuracy of the AI’s recommendations using an incentive-compatible quadratic scoring rule, as well as the...
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...
The purpose of this study is to evaluate whether a universal student support intervention that provides personalized video feedback, recommendations, and action-oriented tasks can improve students' academic and college experiences. The intervention is designed to address common challenges experienced by college students, including study strategies, time management, financial stress, social belonging, and other barriers to academic success. We will examine whether students who receive personalized support demonstrate improvements in outcomes such as academic performance.
This trial investigates whether relief from legal financial obligations associated with misdemeanor criminal offenses leads to decreased criminal justice system involvement and improved labor market outcomes.
Do people hold responsibility-sensitive fairness preferences regarding others' greenhouse gas emissions? We study this question in the context of the German heating transition through an incentivized survey experiment fielded in the German Heating and Housing Panel. In a randomized factorial design, participants allocate carbon pricing rebates between households that differ in responsibility-relevant conditions at the time of their heating technology choice. Exogenous variation in policy environments—information about future CO₂ costs and access to subsidies for climate-friendly alternatives—identifies how information and economic capacity shape judgments of responsibility and deservingness. This allows us to isolate responsibility-sensitive fairness preferences and compare them to inco...
This project aims to understand the drivers of the recent increase in worker collective action in the United States. Since 2020, there has been a surge in union organizing activity, particularly among low-wage retail and service sector workers, that has corresponded with two other shifts in the economy. First, labor market tightness increased dramatically, making it easier for workers to find new jobs. Second, organizing attempts received a great deal of media attention, particularly on social media. Each of these factors could independently facilitate organizing efforts, by lowering the costs of organizing and by improving beliefs about the likelihood that organizing will succeed. These factors could also reinforce each other, further driving increases in willingness to engage in colle...
