In recent years, randomized controlled trials have become increasingly popular in the social sciences. In development economics in particular, their use has attracted considerable debate in relation to the identification of 'what works' in development policy. This paper focuses on a core topic...

In this paper, we investigate both short- and long-term impacts of financial stimuli on public goods provision when contributions are tied to individual harm-related behavior. We conduct a large-scaled field experiment to examine voluntary contributions to a carbon offsetting program during the...

The efficiency properties of price and nonprice instruments for conservation in environmental policy are well understood. However, there is little evidence comparing the effectiveness of these instruments, especially when considering water resource management. We exploit a rich panel of...

Policymakers increasingly use norm-based messages to promote conservation efforts. Despite the apparent success of such strategies, empirical analyses have thus far focused exclusively on short-run effects. From a policy perspective, however, whether and how such strategies influence behavior in...

Many Americans fail to get life-saving vaccines each year, and the availability of a vaccine for COVID-19 makes the challenge of encouraging vaccination more urgent than ever. We present a large field experiment (N=47,306) testing 19 nudges delivered to patients via text message and designed to...

Climate negotiations have largely failed, so a change of course is required. This requires that a sizable group of experts recommend a small, clear set of policy guideposts that lead to a more cooperative treaty. This papers proposes a set of three guideposts and derives them from an analysis of...

In diesem Papier wird untersucht, ob bzw. wie sich im Rahmen des Kyoto Protokolls die globalen Emissionsreduktionsziele mit der ökonomischen Rationalität der beteiligten Länder in Einklang bringen lassen. Den äußeren Rahmen der Analyse bildet eine spieltheoretische Darstellung der...
