Weitzman (2014) proposed that focusing international climate negotiations on a uniform carbon price is more effective than Paris style negotiations in achieving ambitious climate action. We put this hypothesis to an experimental test by simulating international negotiations on climate change in...

Most empirical studies on private climate change adaptation rely on self-reported intentions which often fail to translate into real actions. Consequently, this strand of literature can only insufficiently account for the intention behavior gap (IBG) in climate change adaptation, which...

This paper studies the causal effect of providing information about climate changeon individuals’ willingness to pay to offset carbon emissions in a randomizedcontrol trial. Receiving truthful information about ways to reduce CO2 emis-sions increases individuals’ willingness to pay for CO2...

Laboratory evidence shows that when people have to argue for a given position, they persuade themselves about the position’s factual and moral superiority. Such self-persuasion limits the potential of communication to resolve conflict and reduce polarization. We test for this phenomenon in a...

Non-pecuniary incentives motivated by insights from psychology ("nudges") have been shown to be effective tools to change behavior in a variety of fields. An often unanswered question relevant for public policy is whether these promising interventions can be scaled up. In cooperation with a...

In this paper we investigate behavioral constraints to savings among smallholder farmers in rural Ethiopia. Increasing savings by overcoming such behavioral constraints has been documented to have positive effects on various outcomes such as health, education, and agricultural investments. We...

Taxpayer nudges - behavioral interventions that aim to increase tax compliance without changing the underlying economic incentives of taxpayers - are used increasingly by governments because of their potential cost-effectiveness in raising tax revenue. We collect about a thousand treatment...

Governments increasingly use nudges to improve tax collection. We synthesize the growing literature that evaluates nudging experiments using meta-analytical methods. We find that simple reminders increase the probability of compliance by 2.7 percentage points relative to the baseline where about...

In a field experiment with 341 participants, we study whether social comparisons, either in isolation or in combination with a climate-related moral appeal, can change the use of public and car-related transportation. We do so in the context of a mobility budget offered to employees of a large...
