AEA RCT Registry currently lists 12910 studies with locations in 174 countries.
The existing evidence generally finds that when artificial intelligence (AI) tools are provided to workers, the least skilled gain the most (Brynjolfsson, Li, and Raymond 2025; Noy and Zhang 2023; Peng et al. 2023; Dell’Acqua et al. 2026; Cruces et al. 2026). Of course, that only happens if the least skilled workers adopt these novel tools. However, this same subset of workers appears to adopt AI tools the least. This randomized controlled trial measures the effect of endogenous AI adoption on the productivity distribution among 1,350 students at Cecyteg (Colegio de Estudios Científicos y Tecnológicos del Estado de Guanajuato), a network of technical-vocational upper-secondary schools distributed across Guanajuato, the sixth most populous state in Mexico. Eligible human subjects are Cec...
We run a set of survey experiments to evaluate participation in public consultation meetings and preferences for development projects
We conducted a series of survey experiments to identify individual's public policy preferences regarding AI regulation and AI deployment as a security tool.
Adolescence and young adulthood are formative periods for sexual and reproductive health and emerging autonomy. During this period, young people navigate changing social roles and relationships, including expectations around gender and sexuality and ideas about what constitutes acceptable behavior. Social approval and perceived expectations may therefore shape not only how young women feel able to express their own views, but also whether they feel able to act on those views when engaging with sensitive topics such as contraception. Importantly, individuals respond to the social environment as they perceive it, which may differ from the underlying distribution of attitudes in that environment. Such discrepancies may lead individuals to make decisions partly on the basis of inaccurate pe...
Generative AI can now be used to help citizens move from a mere social concern to a concrete, structured policy proposal. This creates a question for participatory politics: what changes when part of the work of generating a proposal can be supported by AI? AI may matter on the formulation side, by shaping the clarity, structure, feasibility, and appeal of the proposals citizens formulate. It may also matter on the reception side, by shaping how other citizens react to those proposals, especially when they know that AI was involved in producing them. We study these questions in the context of Le Primarie delle Idee, an Italian participatory platform launched in April 2026. The platform allows registered users to develop policy proposals either with the support of a generative AI a...
We study how job seekers evaluate job vacancies and form beliefs about application success. In an incentivized online vacancy-rating study, graduating Business and Economics students in the Rhine-Main area rate a series of experimentally constructed vacancies and report, for each, how likely they would be to apply and their perceived probability of receiving an offer. Based on their answers, participants receive a personalized list of five real vacancy recommendations. The hypotheses, design details, and analysis are specified in a pre-analysis plan and in hidden registry fields, which will be made public after data collection ends in order to avoid experimenter demand effects.
This study examines whether targeted financial information affects household demand for insurance protection, pension and long-term-care preparation, and financial information acquisition. We embed a four-arm randomized information experiment in a large household financial survey in Henan Province, China. Approximately 10,000 adult respondents will be recruited from urban communities, workplaces, county and township locations, rural survey sites, financial-service channels, and elderly or retirement-related settings. Before the experimental intervention, respondents complete a common set of questions measuring household demographics, assets and liabilities, financial fragility, financial literacy, risk and time preferences, economic expectations, insurance participation and protectio...
Money worries, crowded homes and long working days can leave people with little mental energy to spare. This study asks whether everyday stress makes it harder for parents to pick up information about their young children, and whether easing stress helps. We work with about 800 parents of pre-primary children at low-fee and municipal schools in the Mumbai Metropolitan Region. Some parents learn a short breathing routine, cued by a beaded bracelet; others receive the same bracelet as a thank-you gift. Every parent receives a deck of daily conversation cards to use with their child: some cards invite answers that are easy to check, such as counting or naming, while others ask open-ended “why” questions. Over about six months, we measure how parents’ views of their child change, their stre...
Impulso Chileno is a program run by Fundación Luksic that supports small business owners in Chile through a combination of non-reimbursable cash grants and access to a digital training platform called La Brújula ("The Compass"), which offers asynchronous content on topics such as value proposition, sales channels, accounting, and business management. The program targets formalized entrepreneurs with monthly sales between CLP 500,000 and CLP 2,000,000 (roughly USD 500–2,000). This study evaluates the seventh edition of the program (ICH7) using a randomized controlled trial. It seeks to answer two questions: first, whether receiving the program improves business performance compared to not receiving financial support; and second, whether larger grants produce larger effects than smaller ...
This study aims to understand how experimentation affects job search and career choices. We hypothesize that encouraging teenagers’ experimentation of different occupations will affect their job search and ultimately help them make better choices for their career. To test this hypothesis, we designed a field experiment in collaboration with firms where the treatment consists of experiencing the real-life work environment in an occupation that the student had not considered. We compare the treated group to a control group that instead experience an occupation similar (or identical) to their preferred occupation. We have already registered and submitted a pre-analysis plan (PAP) about a similar experiment we conduct with schools. This registration is for a second experiment that will be ...
