AEA RCT Registry currently lists 12333 studies with locations in 171 countries.
This study seeks to understand how intermediaries in the Medicare market advise clients and make Medicare plan recommendations. We also evaluate how intermediaries respond to different consumer cues and measure broker beliefs about how much consumers value different Medicare plan attributes. The results inform a broader study of how intermediaries shape Medicare plan choice.
This study examines how administrative requirements affect intended take-up and targeting of means-tested social benefits. We implement a vignette-based factorial experiment in the IAB Online Panel for Labour Market Research (IAB-OPAL). Respondents evaluate hypothetical minimum-income benefits that vary randomly in benefit amount and administrative requirements, including application obligations, form length, documentation requirements, documentation mode, language assistance, and application channel/travel time. The main outcome is whether respondents would apply for the benefit. We estimate average marginal component effects of administrative requirements on application intentions and express these effects as willingness to pay for avoiding specific requirements. We also study heterog...
This study aims to evaluate the impact of training programs delivered to members of micro and small enterprises (MSEs), as well as to the spouses of female MSE members, on the economic and non-economic outcomes of pastoralists and agro-pastoralists. The first treatment group receives soft skills and group cohesion training delivered through a technology-based (tech-led) modality, while the second group receives the same training delivered by human facilitators (human-led). Furthermore, to foster spousal support for female MSE members, the husbands of female participants receive what we refer to as “spousal support” training through a human-led modality. This is complemented by an edutainment component provided to a randomly selected half of the spouses
This RCT studies whether recommending additional vacancies to jobseekers in Addis Ababa based on a combination of jobseeker and firm preferences increases employment and vacancy filling rates simultaneously. We additionally study whether allowing jobseekers to signal their skills (with a focus on soft skills) through certificates further enhances the effects of recommendations.
This project studies how loan officers and credit professionals evaluate credit applications, and how applicant identity and additional hard information affect credit assessments. We implement an online randomized vignette experiment in Italy with respondents involved in the evaluation of credit applications. Each respondent evaluates three hypothetical credit requests randomly selected from four possible cases: two loans to micro or small firms and two first-home mortgage applications. Within each vignette, we randomize applicant identity using names that jointly signal gender and geographic origin, as well as age, firm age or current employment/self-employment tenure, and the applicant’s relationship with the bank. After an initial assessment, respondents receive additional randomized...
This study will develop and administer a survey of state legislators about health infrastructure, rural health care access, and related policy issues. The study will describe legislators’ views and test how incentives, follow-up efforts, and question framing affect survey responses. It will also examine how legislators' responses relate to health-related characteristics of the districts they represent.
In this project, we will examine how we students and parents can be supported when making early educational choices such as choosing students' field of concentration.
This study uses a lab experiment to examine whether failures of equilibrium reasoning affect support for carbon taxes in a Collective Risk Social Dilemma (CRSD) setting. Pairs of participants play a consumption-based CRSD game with a tipping point. Consumption produces a Byproduct, and exceeding the byproduct production threshold triggers a 70% probability of losing all tokens. The game is played in three variants: a baseline without tax, a game with tax that affects players equally, and a game with tax that creates inequality through redistribution. The tax alters the game's equilibrium, making both the private and social equilibria superior. If a failure of contingent thinking (Niederle and Vespa, 2023) is present, participants may still vote against it if they fail to anticipate how...
We evaluate the causal effect of an intervention that combines gender-sensitive teaching practices with the pedagogical use of Matific, a gamified mathematics platform powered by adaptive artificial intelligence, on reducing gender gaps in mathematics achievement through reductions in girls' mathematics anxiety among students in 3rd- and 6th-grade public schools in Uruguay.
This analysis plan pre-specifies the main analysis of a randomized controlled trial testing whether a larger Roth IRA seed contribution increases retirement saving among young workers in city-run summer employment programs. All study enrollees will be offered an initial $50 contribution conditional on opening a Roth IRA and successfully depositing the $50. Participants who complete this step will be randomly assigned to a higher contribution offer or to a comparison contribution condition. The design may also include an independent messaging-based cross-randomization to test whether reminder intensity or message framing affects Roth IRA engagement. The primary analysis estimates the intent-to-treat effect of assignment to the higher contribution offer on Roth IRA saving behavior, balanc...
