AEA RCT Registry currently lists 4723 studies with locations in 159 countries.
In this trial, we want to test if knowledge regarding partial funding for a social innovation project in Austria from a national public funding agency, the Austrian Research Promotion Agency (FFG), influences the likelihood of participants to invest in a crowdfunding campaign for social innovation projects, compared to just hearing about the crowdfunding campaign itself. The trial will consist of a series of emails to participants, in which new social innovation projects of various SMEs are introduced along with 30 day crowdfunding campaigns hosted on the platform Startnext. There is one control group, and who receives only the previous information, and 2 Treatment groups. Treatment group 1 will receive emails with an additional text saying that the social innovation project will receiv...
We run a large-scale randomized controlled trial (RCT) to examine the impacts of attending an almost year-long intensive training program (Freedom English Academy or FEA) on the English skills, non-cognitive skills, and labor market outcomes of low-income youth in urban India. Specifically, we randomize 1,200 low-income youth in Delhi to one of two conditions: (a) immediate enrollment in FEA or (b) deferred (one-year) enrollment in FEA. After approximately ten months, we measure impacts from attending FEA on labor market outcomes (estimated wages), English listening and speaking skills, and non-cognitive (social) skills.
The urban poor in developing countries are tired: noise, heat, pain, and physical discomfort all interfere with their sleep. Low-income adults in Chennai, India, sleep on average just over five hours a night (based on our pilot studies). How does insufficient sleep affect how these individuals think, work, and make decisions? Can simple and scalable interventions improve sleep among the poor in a cost-effective way? We investigate these questions in a field experiment in Chennai. The randomized controlled trial aims to: (i) evaluate three interventions (devices to improve the home sleep environment; incentives to sleep more; naps at work) to improve sleep among the urban poor; (ii) estimate the causal impact of improved sleep on cognitive function, health, and economic outcomes.
I present a theory on non-linear Public Goods. The Game has a continuum of Nash equilibria in the interior of strategy space which depend on the degree of curvature and what players belief others will contribute. I will use laboratory experiments to test the theory: average contributions in non-linear Games are higher than in quasi-linear Games.
The experiment examines how people make inter-temporal choices when there are risks associated with either the present or the future outcome.
In this project, we will study whether information can affect COVID vaccine uptake. Specifically, we experimentally test the effect of two types of informational videos delivered by Black physicians. The first provide information about COVID 19 vaccine information including information on side effects and emergency use authorization. The second cover aspects relevant to Black populations, e.g.: whether Black people were involved in the development and testing of the vaccine. We test the effect on attitudes, intentions and vaccination rates.
This project intends to improve student's learning experiences and increase student success in online settings at the University of California-Irvine (UCI). The project has two main objectives: (i) to examine the impacts of collaborative learning strategies (structured and organized after-class virtual study groups) on students’ academic and social-emotional outcomes; (ii) to identify promising after-class study group facilitation strategies. To achieve this objective, I will carry out one randomized control trial. The intervention consists of assigning undergraduates to small virtual study groups to encourage them to have more after-class synchronous academic interaction activities and social connections.
An important impediment to the development of the digital economy in middle-income countries is the low rate of digital payments made by consumers (Cheng, 2019). In this experiment, we test how different online-offer conditions affect customers’ intention to buy a product, and their trust in the seller. We conduct a scenario-based experiment among North African consumers, comparing the effects of admitting online-payments only (vs cash-on-delivery), and of offering free returns (vs no returns). Additionally, we compare the effects among a sample of North African consumers to a sample of European consumers. References: Cheng, R. (2019). Policy and Regulatory Issues with Digital Business.

We analyse how risky choice responds to variation in posterior probability and how such responses may explain gaps in the weighting of small probabilities when they are described vs sampled.
This study analyzes the effects of incentives on paternalistic interventions on "repugnant transactions."
