Compliance with COVID-19 measures in the workplace is a vital component of society’s strategy for mitigating the effects of the pandemic. We trial well-established behavioural interventions (social norms, pledging, messenger effects) in a field setting. We use daily reports of own and...

We test the hypothesis that protest participation decisions in an adult population of potential climate protesters are interdependent. Subjects (n = 1,510) from four German cities were recruited two weeks before protest date. We measured participation and beliefs about the other subjects'...

Previous research shows that humans display complexity aversion. In this article, we test for the presence of complexity aversion and its determinants in the context of voluntary climate action, where individual choices interact with the complex regulatory framework of the EU Emission Trading...

We test the hypothesis that protest participation decisions in an adult population of potential climate protesters are interdependent. Subjects (n = 1,510) from the four largest German cities were recruited two weeks before protest date. We measured participation (ex post) and beliefs about the...

Many public goods can be provided at different spatial levels. Evidence from social identity theory and in-group favoritism raises the possibility that where higher-level provision is more efficient, subjects' narrow concern for local outcomes (parochialism) could harm efficiency. Building on...

Evidence from public good game experiments holds the promise of instructive and cost-effective insights to inform environmental policy-making, for example on climate change mitigation. To fulfill the promise, such evidence needs to demonstrate generalizability to the specific policy context....

We study spatially differentiated competition between charities by partnering with two foodbanks in two neighboring cities to conduct a field experiment with roughly 350 donation appeals. We induce spatial differentiation by varying the observability of charities' location such that each donor...
