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 examines the effects of structured social activities on workplace collegiality and performance in a large white-collar firm with 100 geographically dispersed offices. In a randomized controlled trial, half of the offices received subsidies to organize biweekly social events over a...

We study the impact of online instruction with a field experiment that randomly assigns 1,344 university students to different proportions of online and in-person lectures in multiple introductory courses. Increased online instruction leaves men’s exam performance unaffected but significantly...

We evaluate Raise-Up, a pilot in two Turin-area vocational schools that integrated project-based learning on digitization and the green transition into the regular curriculum. Using a difference-indifferences design on three survey waves, we find no positive effects on any pre-registered...

Gender imbalance in time spent on child rearing causes gender inequalities in labor market outcomes, human capital accumulation, and economic mobility. We conduct a large-scale field experiment with a near-universe of US schools to investigate a potential source of this inequality: external...

We run a field experiment in which we provide information to students about job opportunities and hourly wages of occupations they are interested in. The experiment takes place within a widely-used career orientation program in the Netherlands, and involves 28,186 pre-vocational secondary...

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...

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...

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...

We conduct a large-scale randomized controlled trial to examine the effects of time- and location-specific, distance-based road pricing on travel behavior and driving externalities. Using financial incentives and a smartphone app that automatically tracks participants' travel behavior across...

We present results from a field experiment that tests the effects of varying gender and linguistic group composition on performance and on group-members' perception that their voice is heard when completing complex collaborative work within a low scrutiny environment. We randomize individuals...

There is limited evidence on the non-health impacts of air pollution, including productivity in the workplace and behavior. We examine the effect of air pollution on participation, collaboration, and feedback provision in a workplace setting. Our experiment randomly assigns air purifiers to...

Wage information is rare in job adverts, yet crucial for search. To study this information friction, we run a field experiment with real vacancies, randomly adding or withholding wage information. Disclosing wages does not change average application volumes. Instead, it amplifies the wage...

Financial student aid improves educational outcomes and reduces social inequality, yet many eligible students do not take it up. To examine whether correcting misperceptions increases take-up, I conducted an RCT with 6,225 university students across Germany who were not receiving aid. I find...

While almost all charities rely on a set of donor appreciation strategies, their effectiveness for the success of fundraising campaigns is underresearched. Through two preregistered field studies conducted in collaboration with a leading German opera house (N=10,000), we explore the significance...

What motivates workers' referral decisions? Combining a field experiment in a firm and urban social network data, I first show that workers primarily refer those who previously referred them. This reciprocity leads to significant on-the-job productivity losses and excludes less connected...

This study examines how the organizational work climate shapes the effectiveness of supervision on employee performance. While traditional management theory assumes supervision universally enhances productivity, we observe a puzzling paradox: facing identical tasks and wage systems, some firms...

We study the effects on intimate partner violence (IPV) of new information received by women only, men only, or both, relevant to a high-stakes joint household decision. We model communication between spouses as Bayesian persuasion where disagreements elevate the risk of IPV. Our framework...

We assess the impact of discrimination on Black individuals’ job networks across the U.S. using a two-stage field experiment with 400+ fictitious LinkedIn profiles. In the first stage, we vary race via AI-generated images only and find that Black profiles’ connection requests are 13 percent...

This study investigates the impact of a low-cost, color-coded scale intervention designed to inform university students about the expected workload for a course, with the aim of improving students’ academic performance and learning behaviors. An initial intervention took place at the beginning...

Many industrialized countries have recognized the need to mitigate energy cost increases faced by low-income households by fostering the adoption of energy-efficient technologies. How to meet this need is an open question, but “behavioral insights” are likely components of future policy...

This paper examines inconsistencies in the decision-making of a sample of 2,248 adolescents from El Salvador when completing two classic experiments: temporal discounting and risk preferences. Inconsistency in responses is a significant issue when collecting experimental data because it implies...

Behavioral biases often lead to suboptimal decisions, a vulnerability that extends to policymakers who operate under conditions of fatigue, stress, and time constraints--environments ripe for such biases and with significant implications for public welfare. While behavioral economics offers...

Visual Continuous Time Preferences (VCTP) is a new tool for measuring time preferences that synthesizes the simplicity of Multiple Price List (MPL) and the precision of Convex Time Budget (CTB) tasks. We evaluate this tool in the field, in rural Honduras, to test whether running the task with...

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...
