Behavioral feedback interventions typically promote conservation by providing separate reports for individual resources such as electricity, gas, and water. We study whether integrating this information into a single communication improves household conservation. In collaboration with a large Italian multi-utility, we conduct a randomized controlled trial involving approximately 190,000 residential customers who already receive digital Home Reports for at least two resources. Customers assigned to treatment continue receiving the standard resource-specific reports and additionally receive a Consolidated Home Report (CHR), which summarizes overall environmental performance through a single Ecoscore while preserving resource-specific information. The primary outcome is standardized poo...
Advice as verbal communication, plays an important role in the functioning of organizations but is hard to assess and measure precisely. In this study we plan to measure advice-giving ability of individuals in a novel abstract setting by randomly assigning advice from a singlw advisor to many advisees, resulting in a quantitative measure of advice-giving skill. Then for the same advisors we will measure their advice-giving in a more naturalistic setting, resulting in a qualitative measure of advice-giving skill. We will explore if the quantitative measure and the qualitative measure correlate strongly, despite different surface features, a positive finding would suggest that we are measuring a real, transferable individual difference. Moreover, we will explore if advising skill is dist...
This study investigates behavior in first-price common-value auctions with fixed-equity contracts. Subjects will participate in laboratory sessions in groups of three, completing 30 rounds of the “wallet game” in which each bidder receives an independent private signal and the project value equals the sum of signals. Within each round, the seller requires the winner to pay both their cash bid and an equity share of the realized value, with the equity rate randomized across 0%, 20%, 40%, and 60%. In addition, a between-subject treatment varies how point earnings are converted to cash: in the baseline, conversion is linear, while in the treatment it becomes concave, thereby inducing effective risk aversion.
This study aims to experimentally test whether financial constraint, attractiveness of worker benefits, and information and behavioural frictions are significant barriers to social security participation.
This study examines how pharmacists recommend brand-name versus generic over-the-counter pain medications and whether the way a consumer asks for advice affects the recommendation they receive. Although generic medications contain the same active ingredients as their brand-name equivalents and are often less expensive, consumers may still rely on familiar brand names when choosing over-the-counter medications. Pharmacists are well positioned to help consumers make these choices, but relatively little is known about how they communicate this information during everyday interactions. The study will take place in community pharmacies in Ottawa, Canada. Researchers will visit pharmacies while posing as ordinary consumers seeking advice about an over-the-counter pain medication. Pharmacie...
We study the role of skepticism in shaping the adoption of government programs and its diffusion to others, focusing on the context of crop insurance in India.
In this project, we plan to implement a large-scale randomized controlled trial (RCT) that provides newly elected mayors in Peru with training in managerial skills and democratic practices. The intervention, which will target mayors elected in October 2026, seeks to address shortcomings in local public service delivery and citizen dissatisfaction with democracy. Our experimental design will allow us to study three distinct questions: (1) whether strengthening public management skills enables mayors to improve the provision of public goods and services; (2) whether increasing mayors' knowledge of democratic institutions and practices, as well as their ability to negotiate with the political opposition, improves local governance and citizen satisfaction with democracy; and (3) whether man...
The study uses an between-subjects randomized online survey experiment. After completing a pre-test questionnaire on demographics and moral convictions, participants are randomly assigned to a treatment or control group and read a short informational text about hate crime. The treatment group reads an additional paragraph on anti-hate-crime legislation. Participants then complete an Implicit Association Test (IAT) and a questionnaire measuring attitudes related to hate crime. The main analysis examines whether exposure to information on anti-hate-crime legislation affects these attitudes and whether treatment effects are moderated by ex-ante measured moral convictions.
Armed conflict can increase within-group prosociality while reducing prosociality towards members of other groups (Bauer et al., 2016; Barceló, 2026). Although this pattern is well documented, the mechanisms underlying it remain poorly understood, and interventions targeting intergroup relations are rarely evaluated during active conflict. This study examines whether brief reflections on hardship experienced by one's own group or members of other groups affect intergroup attitudes and behaviour, and whether effects depend on the target of reflection. Approximately 3,000 adults across 150 villages in North, Central, and South Darfur, Sudan, are randomly assigned during a face-to-face household survey to reflect on (i) an ordinary daily activity (control), (ii) challenges experienced b...
This study evaluates whether the framing of household maintenance responsibilities affects investment in government-provided thermal housing modules in rural Peru. The modules, distributed through Peru's National Rural Housing Program (PNVR), are designed to improve thermal comfort in high-altitude and tropical communities, but their long-term benefits depend on regular household maintenance. We randomize approximately 1,700 households across approximately 150 communities into three arms: a control group that receives a placebo video, a Sphere arm that receives a video assigning maintenance activities to familiar household roles to promote role clarity and identity congruence, and a Coordination arm that receives a video reframing maintenance as a shared couple responsibility to address...
