Health workers face elevated rates of anxiety, burnout, and low emotional wellbeing, yet few seek support, and specialized mental health services in El Salvador are scarce. This study evaluates strategies to increase voluntary demand for a free emotional accompaniment service, which consists of up to four brief individual psychoeducation sessions on stress, anxiety, trauma, and grief, delivered by trained lay counselors through calls or messages. The study population is public hospital workers in El Salvador who have previously completed general trauma-informed care training between 2022 and 2025. Respondents (N = 1,057) will be individually randomized, with equal allocation across three arms. All arms offer the same underlying service and differ only in the outreach they receive: a ...
This experiment tests whether choices between money sooner and money later depend on how the cost of receiving money sooner is described. It is motivated by Buy Now, Pay Later (BNPL) credit, whose cost is usually paid by merchants rather than shown to consumers as a fee. We plan to recruit 240 students across schools in Bangor University to supervised in-person sessions, completed on their own phones. Each participant answers three short reasoning questions (the Cognitive Reflection Test) and then earns a lottery ticket by counting the zeros in three number grids. The ticket has a 1-in-15 chance of paying a prize of up to £50; everyone receives £2 for taking part. Participants then make ten choices between an amount paid tonight and £50 paid in four weeks, both by bank transfer, with...
We measure cannabis users’ willingness to pay for legal cannabis using an incentive-compatible procedure. We also use a controlled experiment to study the causal impact of i) information about the prevalence of potential health risks in illegal-market cannabis and ii) consumption experience with legal cannabis on the demand for legal cannabis products.
Small and medium-sized enterprises (SMEs) often lack the time, financial resources, and expertise needed to identify suitable public funding opportunities and prepare competitive grant applications. These constraints may prevent promising firms from applying for funding or reduce their chances of success. This study examines how targeted outreach and application support can help firms overcome these barriers and improve their public funding outcomes. We first test whether different outreach messages increase firms’ interest in applying to a grant-support programme. Second, we test whether machine-learning methods can help identify and target firms with greater potential to succeed in competitive public grant programmes. Finally, we test whether providing firms with an AI-based grant-...
Generative AI can substantially raise individual productivity, but whether these gains translate into higher firm performance depends on how AI reshapes work within organizations. This project studies generative AI as an organizational technology through a randomized rollout of a retrieval-grounded legal-AI tool specialized to the country-specific case law, across ~300 small-to-medium-sized law firms. Firms are randomized to delayed access, partial access for approximately half of their lawyers stratified by seniority, or firm-wide access. The design identifies direct effects on users, spillovers onto coworkers who do not receive the tool, and firm-level effects of adoption within the same organizations. It also tests whether effects differ between junior and senior lawyers. To our know...
The cost of living underpins modern welfare measurement but assumes fully rational consumers. In this study, I embed bounded rationality into classical index-number concepts, yielding a behavioural cost-of-living index that is identified with traditional data via revealed preference and which reduces to the classical measure under full attention. Part of this project involves a simple survey experiment studying how accurately consumers perceive prices and inflation that is the subject of this registry entry. Specifically, an online survey of 750 UK adults will estimate prices for a range of everyday goods and services, with half of the sample randomly assigned to receive an informational intervention in the form of feedback comparing their estimates with benchmark prices. The experiment...
Rice straw burning is widely used to clear fields after harvest but contributes to local air pollution and greenhouse gas emissions. This study evaluates approaches to increasing farmers’ use of a microbial product that helps rice straw decompose in the field, providing an alternative to burning. In rice-growing villages in Vietnam, we use a cross-randomization design to evaluate two dimensions of the roll-out of a new technology. More specifically, we test: (i) whether farmers or local agricultural shops help to better spread awareness of and adoption of the product; and (ii) whether top-down (recommendation by village leaders) or bottom-up (peer nominations) invitation procedures for training farmers leads to greater adoption of the product. The study will assess whether these approac...
This study examines whether providing information on the evidence behind a program increases its adoption by government officials. To test this, we exploit the nationwide scale-up of an education campaign in the Dominican Republic and randomly vary whether school officials receive information on the existing evidence of the impact of the program. A treatment arm with financial incentives acts as a benchmark. Further, we analyze whether technical assistance and additional reminders increase take-up.
Female labour force participation rates (FLFP) in India remain substantially lower than global averages and those of similarly positioned countries. This study examines the role of social norms—a key supply-side factor—in declining female labour force participation in Uttar Pradesh, India. We investigate how these social norms and narratives that drive these norms are gendered and how they vary based on women's personal characteristics, specifically marital and parental status, as well as job location. The study further analyzes how making social norms salient influences the probability of job applications.
This study investigates whether consumers are willing to pay a premium for honey produced from ecosystem service practices that provide environmental benefits. We also test whether and how consumers' expected prices and external price information affect consumers' choices and willingness to pay. Participants will complete a series of purchasing decisions for honey with varying prices. This study also examines whether consumers' stated environmental and climate change attitudes align with their actual purchasing choices. The study is being conducted with adult consumers at farmers' markets.
