AEA RCT Registry currently lists 12198 studies with locations in 170 countries.
Bangladesh’s ~7,000 brick kilns contribute substantially to air pollution, responsible for 11% of the country’s particulate matter, 22% of black carbon, and 17% of total annual CO2 emissions . In our earlier work, we developed an intervention, Zigzag 2.0 (ZZK2.0), an intervention offering kiln owners and operators low-cost training and technical support in kiln management and insulation. In a randomized controlled trial with 276 kilns in Khulna Division (2022–2023), 65% adopted the two most important components. Adoption led to 24% less coal use per 100,000 bricks, with 21% reductions in both CO₂ and PM2.5 emissions. At the request of the Ministry of Environment, Forest and Climate Change, icddr,b scaled the intervention across 1000 kilns in 2023-25. Yet, brick kiln workers represen...
We provide cash transfers to select households in Cape Town to assess the income elasticity of electricity use, which we measure using administrative data. The RCT is embedded in a larger project to assess the impacts of subsidized electricity prices.
We investigate the attention and influence that scientific evidence receives in online settings. In an online experiment, participants in the role of "senders" view sets of articles based on research studies, and decide which articles to share and what content to provide alongside the article. We vary features of the articles and the communication process to shed light on the drivers of online attention to different types of evidence. In a separate experiment, participants in the role of "receivers" will choose which articles to click on to read more about.
In a 2x3 design, this study investigates three factors that may matter for group and team decision-making and performance in a portfolio allocation task: cognitive composition, independence, and aggregation. Participants are recruited via Prolific, with an emphasis on recruiting retail investors. They are given a hypothetical $1,000 and financially incentivized to design portfolios that maximize realized Sharpe ratios after 3 months. They design a portfolio alone in Round 1 of the task and again as part of a two-member team in Round 2. We plan to recruit 600 participants to form 300 teams. The two-condition treatment variable targets team cognitive composition, i.e., the distribution of thinking styles among teammates. We define thinking styles as approaches to processing information...
We conduct an online experiment where subjects make two types of choices: one involving monetary lotteries and another involving riskless alternatives, the values of which can be computed through simple mathematical operations. The objective of the study is to evaluate whether subjects display similar behaviors in these two environments and to understand why.
I administer an online survey to approximately three to four thousand parents of parents to measure perceptions of college financial aid, along with a few embedded treatments. The measured perceptions of college aid will inform one paper that measures the welfare cost of misperception of marginal aid phaseout rates. The embedded treatments - which include an information treatment, explainer treatment, savings variation, labor supply framing, and question ordering - may be analyzed in separate future papers.
Rice cultivation serves as a crucial source of livelihood and food security for rural populations. However, traditional farming methods often face significant operational and environmental challenges, including high water consumption and the intense labor required for manual paddy transplanting. Rising agricultural wages, water scarcity, and climate volatility contribute to higher production costs, making traditional cultivation increasingly expensive and less profitable for smallholder farmers. This research aims to address these challenges by proposing a cluster randomized controlled trial that provides technical training on Direct Seeded Rice (DSR) technology along with climate-resilient rice variety. This approach enables farmers to substitute technology for manual labor, reducing t...
This study examines how organizational management styles and artificial intelligence (AI) framing influence the decision-making behavior of street-level bureaucrats in citizen-facing contexts. Using an online survey experiment, participants will be randomly assigned to scenarios that manipulate management style (e.g., bureaucratic, innovative, and participatory) and AI system value framing. Participants will then respond to hypothetical situations and be asked to answer post-vignette survey questions, allowing researchers to assess how these factors shape their behavioral orientations and reliance on AI-assisted recommendations in a decision-making process. This research project involves three research questions: 1) how does organizational management style interacted with role percepti...
This project concerns the evaluation of a mathematics intervention in multi-digit arithmetic. The intervention is rolled out as a Randomized Controlled Trial (RCT) in the fall 2026 in around 100 schools in Denmark with the purpose of improving adaptivity, flexibility, accuracy, and mathematics achievement.
We study how identity salience affects preferences. In an online survey with approximately 2,000 respondents, we randomly assign participants to watch one of two short videos before completing incentivised economic tasks. After the video, respondents complete three tasks.
