Pay-what-you-want is a pricing mechanism where consumers can decide how much to pay for a product or service. Variations of this idea have been employed widely over the years. Public museums, such as New York’s Metropolitan Museum of Art, have long allowed nominally free entry but with requests for donations at entry and/or exit. Panera Bread in the U.S. and the British band Radiohead have both carried out pay-what-you-want arrangements in highly publicized campaigns.
