Behavioral design in smartphone apps aims at inducing certain, monetizable behavior, mainly increased engagement, measurable by usage time. Such design is rarely transparent and often restricts users’ ability to make alternative choices. In a framed field experiment, we document that...

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...

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...

We quantify the impact of Generative Artificial Intelligence (GenAI) on firm productivity through a series of large-scale randomized field experiments involving millions of users and products at a leading cross-border online retail platform. Over six months in 2023-2024, GenAI-based enhancements...

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...

Urged by the European Energy Crisis and the threatening consequences of severe natural gas shortages, energy providers launched gas-saving initiatives incorporating financial incentives to reduce residential natural gas consumption. In collaboration with one of Germany’s largest energy...

We introduce the concept of marginal hassle cost (MHC)–the opportunity cost of time required to complete burdensome administrative tasks–as a measure of non-pecuniary transaction costs. We then propose an experimental procedure to elicit the MHC and validate the approach through a...

We conduct a randomized controlled trial (RCT) with a leading technology firm to study how highlighting flexibility and career advancement in job advertisements causally affects the applicant pool. Highlighting career advancement increases the number of applications from men for entry-level...

Quinoa production in Bolivia's southern Altiplano region takes place under some of the most severe agroecological conditions in the Andes. These include extreme altitude, scarce and variable rainfall, frequent frost, strong winds, and, more recently, widespread soil degradation. Organic soil...

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...

We use data from a Norwegian field experiment where young students were taught mathematics in small, homogenous groups to investigate how treatment effects varied across middle-achieving students dependent on their rank order and their tutors’ instructional practices. We find that individuals...

We re-assess the consequences of a NIT for two-parent families, utilizing hitherto untapped data. The Gary and Seattle experiments fail balancing tests. In New Jersey, Denver and Manitoba we estimate far greater labor supply responses than the current consensus, with remarkable consistency in...

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...

This study presents results from a randomized controlled trial involving 1,085 participants in Switzerland that have access to an E-bike, a car, and public transport. The participants’ transport choices are monitored by means of a GPS-based tracking app. The treatment consists in a monetary...

Bellemare et al. (2023b) examine discrimination against individuals with physical disabilities in the labor market in Quebec, Canada. Their findings indicate that callbacks from potential employers decrease by 25 percentage points if physical disability is (randomly) revealed. Callbacks increase...

This study replicated the research by Bellemare et al. (2023a) to evaluate the transparency and robustness of their findings. We found that computational reproducibility was achieved with ease due to the precise and clear coding provided in their article, and no errors were detected. However,...
