  • Salience of toll ring prices
    Last registered on April 27, 2026

    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.

  • Long term impacts of a successful foundational literacy program in South Africa
    Last registered on April 27, 2026

    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...

  • AI Engagement, Belief Formation, and Human Capital Investment: Theory and Experimental Evidence
    Last registered on April 27, 2026

    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,...

  • AI Predictions, Strategic Disclosure, and Optimal Coarse Bracketing
    Last registered on April 27, 2026

    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...

  • Making Workers AI Ready: Behavioral Interventions and AI Adoption Among Workers
    Last registered on April 27, 2026

    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...

  • Paternalistic Interventions: Determinants of Demand and Supply
    Last registered on April 27, 2026

    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.

  • The Impact of Job Search Requirements and the Salience of Monitoring and Sanctions: Evidence from Integration Agreements for Job Seekers in France
    Last registered on April 27, 2026

    Integration agreements between job seekers and public employment services define mutual obligations for labor market integration, including job search requirements and the conditions under which compliance is monitored and sanctioned. We study how the content and framing of these agreements affect job search behavior and labor market outcomes in the context of the French “Contrat d'Engagement” (Engagement Contract), a mandatory integration agreement signed by job seekers and caseworkers upon registration with the French public employment service, France Travail. The agreement includes a personalized action plan specifying activities to support labor market integration. We implement a large-scale experiment across all France Travail agencies. We randomize agencies into three treatmen...

  • Should we start telling real stories? A survey experiment about Immigration and Redistribution in Austria
    Last registered on April 25, 2026

    We conduct an online survey experiment in Austria to test whether a positively framed narrative about a Syrian refugee shifts attitudes toward immigration and preferences for redistribution. Approximately 1,000 respondents are randomly assigned to watch either a short video telling the success story of a refugee who founded a bakery in Vienna (treatment) or a video about the voting age of 16 in Austria (active control). We measure immigration attitudes along three channels: labor market concerns, welfare state concerns, cultural concerns and elicit beliefs about support for immigration as well as preferred government spending allocations, income tax progressivity, and general support for redistribution. We also elicit prior and posterior beliefs about immigrant population sha...

  • Information Frictions, Algorithmic Matching, and Worker Preference: A Two-Stage Randomized Control Trial on Turnover and Productivity in Manufacturing
    Last registered on April 24, 2026

    High employee turnover remains a persistent barrier to productivity in manufacturing firms. This study investigates the roles of pre-employment information, financial growth incentives, and job assignment mechanisms in mitigating turnover and improving worker-job matches. We conducted a large-scale field experiment with approximately 2,000 newly hired workers in a Chinese electronics factory using a 3 × 3 cross-randomized design. In the hiring stage, we test the effects of information frictions and perceived career growth on selection. Applicants are randomized into: (1) a pure control group; (2) an information treatment viewing a video on factory life and strict workplace regulations; or (3) a "growth path" treatment combining the video with information on on factory life, position-spe...

  • Framing and Financial Incentives to Increase Influenza Vaccination Uptake: A Randomized Controlled Trial in Chinese Communities
    Last registered on April 24, 2026

    This study evaluates whether information framing and monetary incentives increase uptake of the seasonal influenza vaccine among community residents. Participants are individually randomized to one of four information arms: (i) no additional information, (ii) neutral factual information, (iii) positively framed information emphasizing the benefits of vaccination, and (iv) negatively framed information emphasizing the risks of non-vaccination. Participants are also exposed to an incentive module that offers either no subsidy or a randomly assigned subsidy or lottery amount ranging from RMB 10 to RMB 100. The study collects three survey waves: baseline, a midline follow-up 2–3 weeks after the intervention, and an endline follow-up at the end of the influenza season, approximately 3–4 m...
