Fairness crowded out by law: An experimental study on withdrawal rights

Withdrawal rights protect buyers in distance selling, for example when ordering via the Internet. After introducing such a law in Germany the proportion of returned goods drastically increased although most sellers had already offered a return option before. We experimentally investigate scenarios in which sellers can voluntarily offer a withdrawal right. In a second treatment it is provided by law. We find indications that a voluntary provision is perceived as friendly, so that buyers reciprocate by not exploiting sellers too heavily. A third treatment reveals that small return costs for buyers have only a marginal influence on withdrawal behaviour.
