This study tests gain–loss-based reference dependence by examining whether an increase in a hypothesized reference point is offset by an equivalent increase in payoffs. The test does not require parametric assumptions about gain–loss value functions or probability weighting. It accommodates adaptive reference-point rules with parameters estimated from the data, heterogeneity in reference-point adoption, and stochastic reference points. Participants make sixty binary choices under risk. In each round a stock has a displayed current value. The participant either sells the stock at that value or keeps it and receives the value plus the outcome of a die roll. The two arms differ only in the decision screen. The Framed arm displays the current value as its difference from a situation benc...
Forced displacement is a profound economic, social, and psychological shock. Newly arrived refugees must learn how to generate income, access services, and navigate an unfamiliar environment. Many struggle because they lack information, local connections, and confidence. At the same time, more established refugees have accumulated settlement-specific knowledge, skills, and social networks, and may have time and a willingness to help. Search and matching frictions, lack of trust, geographic distance, and uncertainty about others' needs and abilities can nevertheless prevent mutually beneficial relationships from forming. We design and evaluate the Buddy Program, a matching intervention that pairs recently arrived refugee households with more established refugee households in Kyangwal...
This randomized evaluation investigates the impact of a bundled contract-farming model on smallholder farmers’ productivity and climate resilience in Upper Egypt. Farmers in this region face acute exposure to climate risks, particularly extreme heat and limited irrigation, and are often trapped in a cycle of low investment and poor market access. This intervention offers credit to finance climate-resilient inputs for cash crops, coupled with guaranteed contracts and extension services. We randomly assign farmers to one of four groups: (1) offer credit only, (2) offer credit with a recommendation to participate in contract farming and extension services, (3) offer credit conditional on uptake of contract farming and extension services, and (4) control group with no intervention. This...
The research team will be partnering with the American Economic Association to launch a three-year randomized controlled trial of the effects of author-anonymized peer reviewing, commonly referred to as "double-blind." This evaluation will involve the AER, AER: Insights, and the four American Economic Journals. In the treatment group, information revealing author identities will be excluded from materials provided to reviewers, and reviewers will be asked to refrain from seeking them out through web searches or other means. The experiment will test the effects of removing author identities from the information routinely provided to reviewers, while recognizing that reviewers may become aware of author identities in other ways. Key outcomes that will be examined include (1) autho...
This online randomized crossover experiment examines how alternative collaboration arrangements and team incentive structures affect effort and performance in a 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.
Despite constituting the majority of firms in Iraq and contributing to nearly 90% of private-sector employment, small and medium-sized enterprises (SMEs) remain underdeveloped. SMEs have the potential to act as catalysts for economic growth and development in Iraq and other post-war settings, aiding in recovery and generating resources to address socio-economic challenges associated with the return and reintegration of displaced populations. In collaboration with the International Organization for Migration (IOM), we are currently running an RCT involving SMEs that are seeking to expand substantially their business operations, and with a clearly specified set of investments and funding requirements.
We study how an intervention that teaches and encourages Instagram users to curate their own feed affects their content consumption, well-being, political attitudes, and gender norms. The study is a two-wave, individually randomized controlled trial with active Instagram users aged 18 to 35 from the United States (US). In the baseline wave, participants complete a survey and share data on their Instagram content; a randomly assigned treatment group is then shown how to use two built-in curation tools. Roughly six weeks later, an endline wave re-measures the same outcomes, measures further outcomes, and collects the same data on consumed content. We estimate intention-to-treat effects with baseline covariate adjustments and local average treatment effects using random assignment as an in...
Globalization and technological change are rapidly transforming the workplace, generating demand for new skills while rendering other skills obsolete. In this context, having access to training is essential for workers. This study seeks to analyze the influence of age on the likelihood of being accepted into vocational training programs and the impact of this training on hiring probabilities. We hypothesize that age-based discrimination may exist, supported by existing evidence of hiring biases against older workers. Studies reveal recruiters often have negative perceptions of older workers’ cognitive abilities, social and technical skills, flexibility, and salary expectations, leading to an overall negative view of their productivity. To test this, we will send fictitious applicatio...
This study examines whether generative artificial intelligence (AI) affects gender differences in employers’ performance beliefs and hiring decisions. The experiment uses applicant profiles generated from a previously conducted job-seeker experiment in which participants completed mathematics and logic tasks either with or without access to generative AI. Participants acting as employers will be randomly assigned to an AI or no-AI applicant environment and will make ten incentivized hiring decisions between pairs of applicants. They will observe applicant characteristics, including gender, age, high-school arts/science track, intermediate-task performance, and AI-use condition, and will predict each applicant’s subsequent advanced-task performance before making hiring decisions. The exp...
This study examines whether perceived government corruption and national identity causally affect political trust and related political attitudes among Canadians. We use an experimental design that induces exogenous variation in these two constructs to identify their downstream effects on trust, attitudes toward political institutions, and related policy views.
