DR@W ForumWolfson 1, LibraryChristina Gravert (Gothenburg) Title : ‘Hidden Costs’ Abstract: We document the hidden costs of a popular nudge and show how these costs distort policy making when neglected. In a field experiment with a charity, we find reminders increasing intended behavior (donations), but also increasing avoidance behavior (unsubscriptions from the mailing list). We develop a dynamic model of donation and unsubscription behavior with limited attention. We test the model in a second field experiment which also provides evidence that the hidden costs are anticipated. The model is estimated structurally to perform a welfare analysis. Not accounting for hidden costs overstates the welfare effects for donors by factor ten and hides potential |
