Is there a way of matching donations that avoids crowding out? We introduce a novel matching method where the matched amount is allocated to a different project, present some simple theoretical considerations that predict reduced crowding out or more crowding in (depending on the degree of...

While increasingly popular in many domains crowdfunding remains largely un-derresearched and little is known about the best way to encourage participation. In a field experiment we vary suggested amounts and test different wordings for a campaign to finance a club good - an institute's summer...

We study intertemporal crowding between two fundraising campaigns for the same charitable organization by manipulating donors' beliefs about the likelihood of future campaigns in two subsequent field experiments. The data shows that initial giving is decreasing in the likelihood of a future...

Some companies engage in mass fundraising - where thousands of recipients are asked to make small donations - in addition to their core business. Via a corpo-rate social responsibility (CSR) channel this may increase sales. However, recent research uncovered significant "ask avoidance" which, if...

Previous studies of charitable giving have focused on middle or higher income earners in Western countries, neglecting the poor. Despite this focus, the lowest income groups are often shown to contribute substantial shares of their income to charitable causes. In a large-scale natural field...

Is there a way of matching donations that avoids crowding out? And, more generally, what is the best way to utilize a bigger lead gift for raising smaller contribu-tions in a fundraising campaign? To answer these questions, we present a novel matching method, some simple theoretical...

Does online fundraising increase charitable giving? We implemented a natural field experiment across Germany, randomly assigning all of the country's 8,000 zip codes to Save the Children Facebook fundraising videos or a pure control and studied changes in the volume of donations to this and...

We study a form of threshold matching where donations above a certain threshold are topped up with a fixed amount. We show theoretically that threshold matching can induce crowding in if appropriately personalized. In a field experiment, we explore how thresholds should be chosen depending on...
