Whether pro-social preferences identified in economic laboratory experiments survive in natural market contexts is an important and contested issue. We investigate how fairness in a laboratory experiment framed explicitly as a market exchange relates to preferences for fair trade products elicited before and at the end of the market experiment. We find that the willingness to buy at a higher price ...
