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....

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 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 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...

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 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...

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...

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...

Brock and De Haas (2023) study the effect of randomising applicant gender in small business loan applications that are reviewed by loan officers at a Turkish bank in a lab-in-the-field experiment based on real-life applications. The main results are: first, that loan approval rates are not...

We report results from a pre-registered field experiment about the impact of index provider engagement on corporate climate policy. A randomly chosen group of 300 out of 1227 international companies received a letter from an index provider, encouraging the company to commit to setting a...

Many previously incarcerated individuals are rearrested following release from prison. We investigate whether encouragement to use reentry support services reduces rearrest. Field experiment participants are offered a monetary incentive to complete different dosages of visits, either three or...

Urban waste management challenges pose significant health and economic consequences. Although source-level waste segregation offers a promising solution, its success depends on household participation. Through a randomized controlled trial in the capital city of Bihar, India, we evaluate how...

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...

Interventions to decrease meat consumption are often only implemented for short periods of time, and it is unclear how they might have lasting effects. We combine student canteen consumption (over 270, 000 purchases made by over 4, 500 guests) and survey data (N 800) to study how a one-month...

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...

Low-income individuals in developing countries are often inadequately prepared for employment because they lack key labor market skills. We explore how employability and wage outcomes are related to English language skills in a novel, large-scale randomized field experiment conducted in Delhi,...

An extensive literature in the social sciences analyzes peer effects among students, but estimation is complicated by several major problems some of which cannot be solved even with random assignment. We design a field experiment and propose a new estimation technique to address these estimation...

The endowment effect is a phenomenon whereby ownership increases the perceived value of goods, thereby reducing the willingness to trade. This paper presents the results of a field experiment, designed to assess the robustness of this effect when decisions concern unique, nontangible instruments...

This paper studies the relationship between the creative abilities of study peers and academic achievement. We conduct a novel large scale field experiment at university, where students are randomized into work groups based on their score on a creativity test prior to university entry. We first...

The use of Artificial Intelligence (AI) in recruitment is rapidly increasing and drastically changing how people apply to jobs and how applications are reviewed. In this paper, we use two field experiments to study how AI recruitment tools can impact gender diversity in the male-dominated...

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...

This paper presents new evidence on the question: Why don’t consumers switch electricity contracts? By conducting a large-scale survey experiment with 3% of the Danish working-age population, I have gathered data on respondents’ factual knowledge of the retail electricity market, their...
