Abstract
The annual Ottobeuren Seminar on Economics brings together experts on a previously chosen subject. The special purpose of these seminars is to present new theoretical approaches as well as new empirical findings and to discuss the political-economic conclusions with them. This volume contains the papers and discussions of the 38th Ottobeuren Seminar on Economics dealing with the subject of experimental economics. It presents several experiments, some of whose results clearly contradict the predictions of traditional economics and thus provide important incentives for a reformulation of the theoretical approaches.
