Why consumers pay voluntarily: Evidence from online music

Customers at the online music label Magnatune can pay what they want for albums, as long as the payment is within a given price range ($5-$18). Magnatune recommends to pay $8, and on average customers paid $8.20 (Regner and Barria, 2009). We ran an online survey and collected responses from 227 frequent Magnatune customers to gain insights about the underlying motivations to pay more than necessary. We control for individual response- and sample selection-bias, and find that reciprocity and guilt appear to be the major drivers for generous voluntary payments. Being inclined to follow social norms is a positive determinant for payments around the recommended price.
