A rebate subsidy of rate sr is functionally equivalent to a matching subsidy of rate sm=sr/(1−sr). Other things equal, an individual should respond identically to the two subsidies. We test the effect on charitable giving of the framing of a subsidy as a rebate or as a match. Subjects make a...

We report the results of a field experiment conducted in conjunction with a mailed fundraising campaign of a nonprofit organization. The experiment is designed to compare the response of donors to subsidies in the form of matching amounts or rebated amounts. Matching subsidies are used by many...

An individual should be indifferent between a rebate subsidy of rate sr and a matching subsidy of rate sm=sr/(1-sr), and the total amount received by the charity should be the same regardless of subsidy type. Recent laboratory and field experiments contradict these straightforward predictions of...

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...

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...
