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...

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...

We study a form of threshold matching in fundraising 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...

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...

While increasing the number of small donors, standard linear matching schemes have been shown to cause considerable crowding out in charitable giving with pronounced effects on large gifts. We propose a form of threshold matching where donations above a certain, potentially personalized,...
