AEA RCT Registry currently lists 9394 studies with locations in 169 countries.
We conduct randomized survey experiments with US and Canadian residents to study attitudes toward market-based transactions, with a specific focus on whether and how people perceive and elaborate tradeoffs between competing values and goals. In our survey, participants will express their views and preferences over scenarios where companies increase the prices of certain goods in particular circumstances and scenarios where public authorities prohibit these price increases. Our sample will include 4,000 Americans and 4,000 Canadians and it will be representative of the respective populations in terms of gender, race and ethnicity, age, and educational attainment.
A first study in schools in rural Madagascar evaluated the effect of a bundle of hygiene-focused interventions in schools and showed substantial improvements in girls’ learning outcomes (+0.2SD). Building on these results, this study will run a second RCT to disentangle the effects of physical infrastructure from all the other components of the intervention (sensitization and sanitary pads). This separation is crucial for cost-effectiveness analysis (since physical infrastructure is expected to account for about 60% of the per-head intervention cost), and for understanding the mechanisms through which expanding access to infrastructure can complement female empowerment interventions. The study will measure effects on learning, psychosocial wellbeing, and a variety of secondary outcomes.
This study seeks to understand the role of intermediaries in the Medicare market. Specifically, we investigate how quality of insurance advice is correlated with consumer and agent characteristics.
This study examines the role of parental misperceptions and information gaps in contributing to the persistently high rates of child undernutrition in India. It is guided by two core hypotheses: 1) Parents systematically overestimate the nutritional status of their children (if parents form expectations about how healthy their child is by observing other children around them, then parents in areas with high levels of stunting and wasting may be more likely to believe that their own child is relatively healthy), and 2) Parents systematically underestimate the returns to child nutrition on long-term health, education, and labor market outcomes. These misperceptions, if proven true, may create a suboptimal equilibrium for child nutrition outcomes, trapping families in a cycle of inadequate...
In this online experiment, participants perform a perception task under incentives for exaggeration. I study the extent to which perception is influenced by the incentives, the participants' beliefs of such influence, and the effect of providing generic information about motivated perception on the participants' beliefs and confidence.
Raising agricultural productivity among smallholder farmers in Sub-Saharan Africa is widely recognized as an important component of inclusive wealth creation and structural transformation. Central to this endeavor will be the adoption of sustainable soil and land management to improve the sustainability, resilience and productivity of agriculture. As such, government advise farmers to increase soil productivity by embracing the use of fertilizers and implement proper soil health management practices. However, these recommendations mostly come in the form of blanket one-size-fits-all recommendations that ignore heterogeneity in soil characteristics that individual farmers face. Using a cluster randomize control trial, we evaluate the impact of a bundled intervention that involves offerin...
The present research aims to explore the role social distance plays in facilitating trust among customers of a major online retailer. In the context of online shopping, potential customers can not physically inspect the products they want to buy and they largely rely on the product reviews left by previous buyers for the first-hand insights on the product quality, suitability and decide whether the products are worth buying etc. However, product reviews, regardless how positive they are, will need to be trustworthy in the eyes of the potential buyers to have any effect given that 'fictitious product reviews' are now a wide-spread phenomenon in the competitive e-commerce business. In this setting, we explore whether a key social distance-reducing measure, that is showing the product revi...
Since the pandemic, working a couple of days per week remotely from home has become the norm in many organizations. This transition, while granting newfound flexibility, also presents challenges. Employees may feel compelled to remain constantly connected to the workplace, particularly because digital communication tools enable virtual accessibility from anywhere. Research suggests a correlation between employee well-being and productivity regarding email and meeting practices. In this research, we conduct a randomized controlled trial (RCT) within a Belgian public administration to assess the impact of nudges (focusses) aimed at alleviating digital communication overload. The study seeks to assess how these nudges affect employee productivity and well-being. The intervention involv...
We propose an experimental method, Strictly Concave Budget Restrictions, to determine preference parameters precisely with the lowest possible number of observed choices. Our approach extends a method that is commonplace in economics for estimating preference parameters: the analysis of choices that were made subject to linear budget restrictions. Compared to other elicitation methods, budget-based approaches allow for relatively precise estimation of the preference parameters that govern individuals’ choices. This is the case, however, only as long as individuals choose interior allocations. It has turned out across numerous experimental studies that the majority of choices from linear budgets are corner allocations. The main idea of Strictly Concave Budget Restrictions is to encourage...
There is evidence that non-cognitive characteristics of school peers, such as disruptiveness or engagement impacts other students' outcomes. It remains an open question how large is the influence of disruptive peers on student outcomes. We develop a survey experiment in which individuals are exposed to randomized scenarios of students being disruptive in the classroom. Participants are asked whether they think that the scenario of disruptive students they are exposed to could influence them in terms of study motivation, career aspirations, their science study readiness, and their career readiness.
