In his research, Sören Köcher provides valuable insights on the paradoxical effects of the magnitude of a loyalty program mediumi.e. the sheer number of points, miles, or stamps credited for every purchase and required for reward redemptionon the central consumer decisions in loyalty program memberships. In sum, the results of twelve empirical studies reveal that high magnitude currencies improve the attractiveness of medium collection but entail reluctant medium spending behavior. These findings provide important implications for a more efficient usage of loyalty programs in business practices. In addition, this dissertation discovers a violation of one of the most fundamental assumptions of rational choice theory and thus contributes to a better understanding of when and why people deviate from rational decision-making.
