Job search frictions — including limited access to information, weak networks, and skills mismatches — are significant barriers to employment for technical diploma graduates in low- and middle-income countries, with women facing additional constraints around mobility, household responsibilities, and discriminatory norms. In Bangladesh, employment outcomes for technical diploma graduates remain weak despite substantial government investment in technical and vocational education and training, and use of digital job search platforms is limited. This study aims to identify scalable approaches to improving the school-to-work transition for technical diploma graduates in Bangladesh, with a particular focus on gender. The intervention introduces and trains final-year technical diploma stude...
We use a series of survey experiments embedded over multiple rounds of a panel survey to study the sources, causes, and remedies of measurement error in survey data. The topical focus of our surveys is on living standards, extreme climate events, and their interaction with welfare at the household and intra-household level. Within each survey round, we randomize survey mode (in-person vs. over the phone), collect a series of data quality proxies, and conduct a range of experiments to study mechanisms.
Cashew is one of Mozambique's most important agricultural export crops and a significant source of income for rural households, supporting roughly 1.5 million smallholder farming families concentrated in the northern provinces. Farmgate prices vary widely across locations and marketing channels, and farmers often sell without timely knowledge of the IAM reference price announced ahead of each harvest season, which may limit their ability to assess and negotiate the offers they receive. This study uses a village-level randomized controlled trial to measure whether providing smallholder cashew producers in Nampula Province with reference price information ahead of the selling season raises the farmgate prices they receive. Approximately 500 cashew-producing households across 70 villages ...
We use a randomized controlled trial to investigate the impact of a large call- and WhatsApp-driven intervention aimed at enhancing parental participation in their child’s education on foundational learning outcomes of children. The intervention consists of the following elements: a) telephonic assessment of the child using simple assessment tools, b) communicating result to the parents, c) sharing practice material over WhatsApp, and d) periodic calls to encourage parents to adopt specific practices to facilitate child’s learning. The baseline was conducted between November 2025 and January 2026. The endline will be conducted during August to September 2026. 5644 children spread across various locations in Delhi (India) were randomized in treatment and control groups. Children...
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...
