Doing the right thing (or not) in a lemons-like situation: on the role of social preferences and Kantian moral concerns

Abstract: We conduct a laboratory experiment using framing to assess the willingness to sell a lemon'', i.e., to undertake an action that benefits self but hurts the other (thebuyer''). We seek to disentangle the role of other-regarding preferences and (Kantian) moral concerns, and to test if it matters whether the decision is described in neutral terms or as a market situation. When evaluating an action, morally motivated individuals consider what their own payoff would be if -- hypothetically -- the roles were reversed and the other subject chose the same action (universalization). We vary the salience of role uncertainty, thus varying the ease for participants to envisage the role-reversal scenario.
