AEA RCT Registry currently lists 11983 studies with locations in 170 countries.
The project examines the impact of information on prospects in working life - in terms of opportunities for professional reorientation. Randomly drawn individuals receive information and an access link to the Federal Employment Agency's online exploration tool New Plan - Inspirieren. New Plan - Inspirieren is designed to actively support people in their search for career reorientation opportunities. To this end, information on alternative occupations, such as earning potential, employment opportunities and job availability, is provided in a clear and individually tailored manner.
This study focuses on the impact of healthcare short-form videos on healthcare quality. It aims to design AI-generated short videos and a patient-customized AI video intervention model for healthcare delivery. We propose an intervention-based field experiment conducted in partnership with a major hospital in China and a leading AI technology firm to evaluate the impact of different interventions on health information dissemination and patient recovery outcomes.
Venezuelan migrants in Colombia often encounter xenophobia and exclusion, heightened by misinformation circulated on social media. To help counter these dynamics and improve public perceptions of migrants, the World Bank has partnered with a Colombian audiovisual company to produce a new edutainment intervention –a web series designed to engage and inform through storytelling, seeking to enhance message retention and emotional processing. Produced in Colombia, the series tackles challenges faced by migrants, emphasizing their resilience. Its novel format of short episodes distributed on digital platforms aims to reach audiences prone to misinformation on social media while remaining low-cost and scalable. To evaluate this intervention, researchers plan to vary the content and format...
Mobile phones can enable economic and social empowerment by lowering communication costs and reducing information frictions. Yet, gender gaps in smartphone ownership in sub-Saharan Africa are substantial. The high up-front cost of smartphone devices remains a primary barrier, especially for women. Credit is one way to overcome this barrier, but it is often difficult for lenders to extend credit to low-income borrowers, who lack collateral and therefore pose a risk to default on their loans. Recent research indicates that a “pay-as-you-go” (PAYG) structure -- which relies on technology that locks the asset being lent in the event of non-payment -- could be an effective means of lending to the large numbers in low- and middle-income countries with no credit history. However, the rigid nat...
This study investigates the effect of providing information and making costs associated with car use more salient. Specifically, we will study the impact of informing drivers about road toll prices over time on driving behavior and attitudes.
We estimate the long-term impacts of a foundational literacy program, the Early Grade Reading Study I (EGRS I), implemented in South Africa between 2015 and 2017. The project seeks to understand whether initial improvements in literacy skills from early-grade interventions translate into sustained academic progress and completion of high school. We will track students approximately 10 years after the program began, measuring outcomes in 2025 when non-repeating students would be in Grade 11, augmenting this data with administrative data on grade attainment and high school completion. Research questions. 1. What is the long-term impact of the early grade literacy intervention on the probability of completing high school with university eligibility? 2. What is the cost-effectiveness...
This study examines whether a structured AI-assisted advising session changes students' beliefs about their own academic ability and alters their course enrollment decisions. Students approaching a real course registration decision are randomly assigned to one of three arms: a control group (no session), a productivity arm (AI practice session without feedback), and a feedback arm (AI session with a personalized readiness assessment). The primary outcome is enrollment in a harder course track. Secondary outcomes include belief updating (posterior minus prior pass probability) and end-of-semester grades. The design tests a theoretical model in which AI functions as an endogenous information production technology: students who engage more intensively receive more precise self-assessments,...
This study examines how the presentation of delivery-time predictions affects user behavior and satisfaction on a large digital logistics platform. Online platforms often provide estimated delivery times, but these predictions are inherently uncertain. Platforms must decide how precisely to present this information—for example, as a specific time, a broader time window, or with additional shipment checkpoint updates. In collaboration with a large logistics information platform, we conduct a randomized controlled field experiment in which users are randomly assigned to different versions of the shipment-tracking interface. The experiment varies three main dimensions: the type of prediction model used, whether intermediate shipment nodes are displayed, and the precision of the predicted d...
Many workers report feeling stressed or threatened by AI, even though existing evidence suggests limited negative effects on overall employment or mental health. Such perceptions can slow the adoption of AI tools and reduce engagement with reskilling opportunities. This study asks whether simple informational interventions and transparent AI use policies can immediately increase AI adoption and influence both task outcomes and workers' experience of using AI in a workplace setting. Participants first complete a screening Survey (S0) designed to identify valid and attentive respondents. In Survey 1 (S1), participants are randomly assigned to one of four experimental conditions in a 2x2 factorial design crossing two independent interventions. The first is an informational intervention hi...
Interventions by governments, experts, and parents in the lives of others are commonly motivated by a desire to help. What factors influence individuals’ willingness to intervene in the decisions made by others? What factors influence individuals’ attitudes toward paternalistic interventions imposed upon them? We conduct an experiment in a general population sample of the U.S. to address these questions.
