AEA RCT Registry currently lists 9614 studies with locations in 169 countries.
We describe the analysis plan for an online intervention designed to examine how inducing participants to think about the values instilled in the military affects values and views related to nation-building, civic values, and social cohesion more broadly. The study will be conducted online with men of 45 years and older living in Argentina. Participants will share their opinion about the lessons and values that serving in the military taught those who were conscripted. The primary experimental treatment is the order in which individuals respond to this open-ended question. We outline the study design, the treatments, the main heterogeneous treatment effects that we will examine, and the econometric strategy for the analysis.
We describe the follow-up to a study previously registered and conducted in February and March of 2022. We recontact a set of participants from the original study (AEARCTR-0008950) to ask them a new set of questions, and we survey a different sample of Argentinian men to ask them some of the original questions plus the new set of questions answered by those who we re-contact.
The main goal of this study is to understand whether individuals might prefer to avoid situations where they have to engage in sabotage, both as a saboteur and as a possible victim of sabotage. Specifically, this study looks at whether individuals might be willing to give up some expected payment to avoid engaging with sabotage and whether this willingness might differ across individual demographics (gender) and characteristics (altruism). This study will also look at whether the willingness to sabotage, and preferences for competition (with or without sabotage) differ across these same characteristics (i.e., gender and altruism) in its ancillary analysis.
At least ten countries across Africa, including Rwanda, Uganda, Zambia and Namibia, are currently undergoing secondary curriculum reforms to teach youth the skills they need to succeed after school. Yet many of these reforms are not effective due to implementation challenges, particularly the prevalence of traditional rote-memorization pedagogy. This study will examine pedagogy-targeted curriculum reform and teacher training in the delivery of Rwanda’s revised secondary school entrepreneurship curriculum, to be introduced in 2016. A subset of schools will be randomly selected to receive two years of ongoing teacher training on the curriculum. A control group will receive the curriculum only. The study will measure impact on student academic and life outcomes over a period of three years...
We study the efficacy of rating systems, similar to the one used in online marketplaces. In this study, we investigate the effectiveness of rating systems in assisting consumers with product selection, focusing on both vertical and horizontal markets. Additionally, we explore the impact of grouping ratings and implementing freezing periods on welfare in horizontally differentiated markets. Our research aims to answer the following questions: 1. Does the introduction of a rating system increase welfare in vertically differentiated markets? 2. Does the introduction of a rating system increase welfare in horizontally differentiated markets? 3. Does providing average reviews broken down by relevant individual characteristics (filtering) increase welfare in horizontally differentiated...
Exclusion can damage group member's health and work performance. The central objective of the study is to understand the patterns of exclusion and whether the information on the likelihood of being excluded helps or harms the victims. In our laboratory study, we invite a set of subjects about whom we have information in multiple dimensions, including age, gender, body type, face shape, eye and hair color, willingness to trust and reciprocate, degree of altruism, etc. Subjects are assigned to groups of six. Using the distributions of the attributes, we create fictional person cards and ask the subjects to rank them according to the expected likelihood that they will be excluded by their group of six. Subjects receive a positive payoff for each person card that they rank on the same posit...
This project aims to understand the downstream effects of different types of content posted on online platforms. This involves running a field experiment in which different types of content are posted on an online platform and the effects of posting such content, e.g. user engagement and follow-on content production, are then examined.
Over the past decades central banks around the world have become increasingly likely to communicate their policy decisions and the rationale that led to them. Traditionally, this communication is aimed at select groups of experts. However, communicating with the general public is of no lesser importance. One issue facing central banks that want to communicate with the public is that the public rarely engages with the central banks directly. Instead, the public is more likely to receive news about the economy through the media. The aim of this research is to investigate how the public's inflation expectations and trust in the central bank is impacted by media reporting vis-a-vis direct communication from the central banks.
This study investigates the effectiveness of two different features of e-learning when teaching an introductory economics course. Specifically, this study zooms into the education production function determining the influence of text vs. video-based learning on test outcomes and learning.
This economic lab in the field experiment tests the effects of recognition on voluntary contributions to a public good at the onset of a behavioral intervention. Using a within-subjects design to look at the behavioral differences between no recognition, group and private recognition; three hundred employees participated in an on-line public goods game before the intervention. After the intervention, a new selected sample was part of the same past design. Recognition has a sizable effect on contributions. The intervention improves the response to private recognition but, strikingly, it has a distributional effect on the cooperative response to the group recognition.
