In this paper, we conduct a large-scale field experiment to investigate the manipulability of prediction markets. The main experiment involves randomly shocking prices across 817 separate markets; we then collect hourly price data to examine whether the effects of these shocks persist over time....

This study analyses the influence of geographical origin and taste on honey consumer behavior. First, we explore the influence of geographical origin on consumers' hedonic evaluation of honey. We then assess the influence of geographical origin and taste on their willingness to pay (WTP) for...

We conduct a field experiment studying how financial incentives for achieving specific course grades affect university students, whether effects vary by ability, and whether allowing students to choose their goals improves outcomes. We find that incentives negatively affect performance,...

Islam (2019) reports results from a randomized field experiment in Bangladesh that examines the effects of parent-teacher meetings on student test scores in primary schools. The reported findings suggest strong positive effects across multiple subjects. In this report, we demonstrate that the...

We conduct a field experiment with job seekers to investigate how feedback influences job search and labor market outcomes. Job seekers who receive feedback on their ability compared to other job seekers update their beliefs and increase their search effort. Specifically, initially...

Inequality is a dynamic phenomenon, and the relative and absolute positions of individuals are subject to frequent shocks. It is important to know if preventive interventions mitigate adverse inequality effects of labor market shocks. We consider individuals up to three months before the...

This paper presents the results of a field experiment aimed at reducing the gender bias in teaching evaluations at a higher education institution. In the intervention, before they completed the teaching evaluation questionnaire, students were individually randomized in three groups. One third...

We study the value of skill management in organizations. In a natural field experiment with 2,582 service technicians, we vary managers' ability to monitor and manage employee skills. We find that removing managers' access to hard information on employee skills reduced training intensity, work...

We study the effect of peer coaching separately from the effect of training on teachers' implementation of new teaching techniques. We conducted a preregistered field experiment involving 68 teachers and 1,490 students in Denmark. Teachers in an active control group took part in a teaching...

Islam (2019) reports results from a randomized field experiment in Bangladesh that examines the effects of parent-teacher meetings on student test scores in primary schools. The reported findings suggest strong positive effects across multiple subjects. In this report, we demonstrate that the...

Aalen et al. (2024) examine the effect of employment on political participation among women job applicants living with a partner in Ethiopia, using 'intention to treat'-estimates and data from a randomized control trial in the field. In the first stage, the authors find that job offers increased...

This paper presents the first rigorous evaluation of school-based interventions aimed at reducing LGBTphobia. We focus on a classroom intervention that addresses the issue of LGBT harassment through perspective-taking and narrative exchange. Using a field experiment in France with more than...

Most social media users have encountered harassment online, but there is scarce evidence of how this type of toxic content impacts engagement. In a pre-registered browser extension field experiment, we randomly hid toxic content for six weeks on Facebook, Twitter, and YouTube. Lowering exposure...

We conduct a field experiment with job seekers to investigate how feedback influences job search and labor market outcomes. Job seekers who receive feedback on their ability compared to other job seekers update their beliefs and increase their search effort. Specifically, initially...

We conducted a large-scale and long lasting randomized field experiment at the donation centers of the Belgian Red Cross-Flanders to study the impact of a small extra reward for plasma donations. Donors normally receive one thank-you-coupon (worth €1.5) for a blood donation and two coupons for...

A large share of the global workforce lacks access to employer-sponsored retirement plans. In Colombia, where labor informality is high, the government introduced the Beneficios Economicos Periodicos (BEPS) program to promote voluntary retirement savings. However, many enrollees fail to...

We conduct an artefactual field experiment in real-existing trade networks to analyze how individual network degree affects bargaining demands and outcomes. We combine data from a bilateral bargaining experiment with data of trade networks in 24 villages in Uganda. To identify the effect of...

Effective and scalable strategies for promoting youth mental health are urgently needed. We conducted a randomized controlled trial to assess the impact of school-based, teacher-led coping skills instruction on youth mental health and academic achievement. The trial included 84 classes and 1,879...

We study the impact of online information provision to unemployed job seekers who are looking for work in occupations in slack markets, i.e. with only few vacancies per job seeker. Job seekers received suggestions about suitable alternative occupations, and how the prospects of these...

Tax evasion is associated with high social and fiscal costs. To address these, many governments employ behavioral interventions given their low implementation costs and high potential efficiency. Although many studies report positive effects of behavioral interventions to combat tax evasion, the...

Physical lab experiments have played an instrumental role in sculpting the history of experimental economics, facilitating controlled information conditions, efficient monetary inducements, and exclusive advantages via immediate human interaction and engaging experiences. These unique benefits...

Can providing information to potential migrants influence their decisions about risky and irregular migration? We conduct an experiment with over 7,000 secondary school students in Guinea, providing information through video testimonials by migrants who settled in Europe and through aggregate...

We study how investors respond to inflation combining a customized survey experiment with trading data at a time of historically high inflation. Investors' beliefs about the stock return-inflation relation are very heterogeneous in the cross section and on average too optimistic. Moreover, many...
