Charity as a Quality Signal

Charity as a Quality Signal

Reviewed by Faisal Zaidi

Daniel W. Elfenbein, Raymond Fisman and Brian McManus found that attaching a charitable donation to a product listing helps most where the seller has no reputation, and argued that the donation works as a substitute for one. Buyers facing a stranger read a costly, voluntary commitment as evidence of a seller worth dealing with. It is the narrowest and best-evidenced version of the idea that purpose moves money, and its narrowness is the finding.

What it is

The evidence is observational but unusually clean in design. A diverse group of eBay sellers effectively ran their own experiments by varying the presence of a donation across sets of otherwise matched product listings, which lets the donation be compared against itself rather than against a different seller. Consumers responded positively to the charity-tied listings, and most of the benefit accrued to sellers without extensive histories on the platform. Consistent with the signalling account rather than with simple goodwill, the authors also found fewer customer complaints among charity-intensive sellers, which is what you would expect if the donation is correlated with the quality it is standing in for.

In effect

The mechanism explains an otherwise odd pattern in the wider literature, which is that social commitments do the most work exactly where buyers have the least other information to go on, and the least work for established firms whose quality is already legible. It also sets a boundary on the standard advice, because a brand with a long record and visible reviews is the case the study found gained least. The working-paper version of the same research adds that charity-tied products were more likely to sell and attracted higher prices, and that the benefit rose for all sellers immediately after Hurricane Katrina, which the authors read as consumers deriving direct utility from seller charity when charity is salient.

What it does not say

It does not come with magnitudes. The published paper is closed, its abstract carries no numbers, and the number of listings, the size of the price premium and the size of the sales effect are not established here, so this page quotes the direction and does not count. The Katrina result and the price claim are from the 2009 National Bureau of Economic Research working paper rather than from the published article, and are marked as such wherever they are used. And it does not license the general claim that purpose sells, since the paper's own result is that the sellers with reputations gained least from it.
