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...

We present experimental evidence that illuminates the trade-off between efficiency considerations and social identity concerns in an inter-city multilevel public goods game. In total, 616 inhabitants of Heidelberg and Mannheim take part in an online experiment in which they can allocate an...
