We contribute to the literature on how program design affects program performance among vulnerable groups by studying the effects of varying the subsidy level and program procedures in an energy efficiency assistance program targeting low-income households in Germany. Eligible households...

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...

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...

In the context of tight public budgets and increasingly ambitious climate objectives, the performance of the support policies for residential energy conservation works needs to be assessed. We compare the performance of four types of support schemes in France, namely the income tax credit, a...

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...

We study the effect of a subtle change in the choice architecture on offsetting behavior. In a large-scale field experiment, we examine repeated voluntary contributions to a carbon offsetting program during the online purchase of long-distance bus tickets. In the control group, travelers had the...

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...

Recent contributions to the theoretical and experimental literature suggest that minimum participation rules (MPRs) are able to reduce free-riding incentives and may facilitate cooperation (or at least coordination) at the extensive margin of international environmental agreements. Based on a...

From a current perspective the Paris Agreement is not sufficient to limit the global mean temperature below 2°C above pre-industrial level as intended. The Agreement stipulates that parties review, compare and ratchet up efforts to combat climate change over time. Within this process,...

In this experiment, we endogenize the choice of which contribution scheme is implemented in a public goods game. We investigate three rule-based contribution schemes. In a first step, players agree on a common group provision level using the principle of the smallest common denominator....
