This online randomized crossover experiment examines how alternative collaboration arrangements and team incentive structures affect effort and performance in a timed visual retail task. Each participant completes four incentivized rounds under four collaboration conditions presented in a randomized, counterbalanced order. We plan to recruit up to 325 participants, targeting at least 264 analyzable participants.
This study examines how restrictions on tenant screening affect landlord behavior and discrimination in rental housing. We conduct a correspondence experiment in Maryland around the October 1, 2026 implementation of two statewide renter-protection laws: HB 315, which restricts the use of income and credit information when screening applicants receiving income-based housing subsidies, and the Fair Chance Housing Act, which restricts criminal-history and substance-use screening. Rental inquiries independently vary applicants’ race, disclosed Housing Choice Voucher (HCV) status, and signals of applicant quality. We measure landlord responses, response timing, invitations to proceed, requests for additional information, and response content, as well as screening and subsidy-related language...
This lab experiment investigates how price controls in emissions permit markets affect incentives for the adoption of new technology that lowers abatement costs. A theoretical model shows that the investment incentives depend on (i) the specific placement of the price collar (defined by price ceilings and floors) and (ii) the size (width) of the collar. The experimental setting includes uncertainty in emissions and abatement costs, and heterogeneous firms. Firms are more likely to adopt the new technology when the collar raises the expected permit price relative to a no-price-control baseline, especially when the high collar is narrow. Conversely, adoption incentives are weaker when the collar lowers the expected permit price, especially when the low collar is narrow. Prices are determi...
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.
