  • Public or Private? Job Preferences Among Students in Côte d’Ivoire
    Last registered on June 06, 2026

    In Côte d’Ivoire, as in many developing countries, young graduates from elite schools face a choice between joining the public sector, perceived as a source of stability and social prestige, and turning to the private sector, which is associated with economic dynamism but often with greater insecurity. This study aims to analyze the preferences of high-achieving Ivorian students between public- and private-sector job offers by assessing the value they place on job attributes. We also tested these students’ beliefs by randomly assigning, through an RCT, the results of a similar study conducted in 2024. The questionnaire was administered to students at ENSEA, INPHB, and ESATIC in lecture halls where students had been specifically gathered for the occasion.

  • Waiting Instead of Working: Experimental Evidence on Willingness to Work after Delayed Task Access
    Last registered on June 06, 2026

    Legal or administrative barriers—such as employment bans for asylum seekers—can prevent people from working even when they initially would like to. This study examines whether such temporary barriers reduce people’s willingness to work both during periods of restricted access and after the barriers are removed and explores possible mechanisms driving these effects. In a multi-day online experiment, participants repeatedly choose between a well-paid work option and a lower-paid leisure option. In one treatment, participants are repeatedly prevented from carrying out the work option they choose and are instead assigned to leisure, creating a situation in which access to work is externally restricted. In a control group, participants always have full access to the work option. The main g...

  • Cost Efficiency in Microfinance Loan Recovery: Can a Simple Message Be Effective?
    Last registered on June 06, 2026

    Microfinance institutions (MFIs) serve as a crucial financial bridge for underserved populations, particularly in developing nations where traditional banking services are inaccessible. However, these institutions often face significant operational challenges, including the high costs associated with administering and recovering small loans. Intensive borrower monitoring, frequent field visits, and default risks contribute to higher interest rates and operational costs, making borrowing increasingly expensive for low-income individuals. This research aims to address the challenges of high operational costs by proposing a behavioural experiment that utilises faith-based nudges to enhance cost efficiency. This approach enables MFIs to lower interest rates or Islamic MFIs to reduce their m...

  • Improving worker conditions in Brick kilns: A Randomized Controlled Trial in Bangladesh
    Last registered on June 05, 2026

    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...

  • The income elasticity of energy use
    Last registered on June 04, 2026

    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.

  • Evidence and Influence
    Last registered on June 04, 2026

    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.

  • Systematic determinants of group and team performance in a portfolio allocation task
    Last registered on June 04, 2026

    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...

  • Characterization Failure, Confidence, and Choice: A Behavioral Welfare Analysis of Decisions Under Risk and Certainty
    Last registered on June 03, 2026

    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.

  • Family Understanding of College Financial Aid
    Last registered on June 03, 2026

    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.

  • Effects of Direct Seeded Rice on Farm Labor and Productivity
    Last registered on June 03, 2026

    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...
