We experimentally test a theoretically promising amendment to the ratchet-up mechanism of the Paris Agreement. The ratchet-up mechanism prescribes that parties’ commitments to the global response to climate change cannot decrease over time and our results confirm that its effect is...

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...

International climate negotiations have so far failed to produce ambitious climate cooperation. We combine laboratory experiments with simulations to investigate the performance of two negotiation design features to address this failure: The Paris Agreement's ratchet-up mechanism, which requires...

In this paper, we investigate whether dynamic incentive schemes lead to a ratchet effect in a social dilemma. We test whether subjects strategically restrict their contribution levels at the beginning of a cumulative public goods game in order to avoid high obligations in the future and how this...

A growing experimental literature studies the endogenous choice of institutions to solve cooperation problems arising in prisoners' dilemmas, public goods games, and common pool resource games. Participants in these experiments have the opportunity to influence the rules of the game before they...

We test whether and, if so, how incentives to promote pro-social behavior affect the extent to which it spills over to subsequent charitable giving. To do so, we conduct a two-period artefactual field experiment to study repeated donation decisions of more than 700 participants. We vary how...

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...

With the increasing recognition of the use of reforestation measures as a complement to conventional carbon emissions avoidance technologies it is important to understand the market valuation of local forest carbon sinks for climate change mitigation. We conducted a framed-field experiment among...

We use car-level micro data to provide empirical evidence on the usage of conventional and electric vehicles (EVs) in private and car sharing fleets in Germany. We shed light on both monetary and non-monetary barriers to EV adoption and usage by exploiting the feature that variable costs are...

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...
