We present online-experimental evidence that challenges the generalizability of established results on subsidizing giving by considering a "quantity donation" scheme. We define this scheme as one in which donors choose how many units of a charitable good to fund, rather than the amount of money...

An influential result in the literature on charitable giving is that matching subsidies dominate rebate subsidies in raising funds. We investigate whether this result extends to 'unit donation' schemes, a popular alternative form of soliciting donations. There, the donors' choices are about the...

Technological progress offers new and promising ways to provide targeted information to consumers and facilitate behavioral change. We conduct a randomized controlled trial with a global supermarket chain and food producer to evaluate the effectiveness of a targeted information intervention that...

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 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...
