Sanctions are a common method to discourage free-riding in the provision of public goods. However, we can usually only sanction those who are detected performing the bad act of free-riding. There has been considerable research on the type of sanctions imposed, but this research almost always...

Eine gelebte Vertrauenskultur ist ein wichtiger Wettbewerbsvorteil für Unternehmen. Vor allem in Zeiten von Digitalisierung und zunehmender Komplexität bildet Vertrauen eine Grundlage für erfolgreiche Zusammenarbeit. Wenn hingegen Kontrollen und Compliance die Kultur eines Unternehmens...

One fundamental assumption often made in the literature on unawareness is that risk preferences are invariant to changes of awareness. We study how exposure to unawareness affects choices under risk. Participants in our experiment choose repeatedly between varying sure outcomes and a lottery in...

In recent years a large number of experimental studies have documented the existence of strong reciprocity among humans. Strong reciprocity means that people willingly repay gifts and punish the violation of cooperation and fairness norms even in anonymous one-shot encounters with genetically...

The paper reports laboratory experiments on a day-to-day route choice game with two routes. Subjects had to choose between a main road M and a side road S. The capacity was greater for the main road. 18 subjects participated in each session. In equilibrium the number of subjects is 12 on M and 6...

In the economic literature on market competition, firms are often modeled as single decision makers and the internal organization of the firm is neglected (unitary player assumption). However, as the literature on strategic delegation suggests, one can not generally expect that the behavior of...

When using the strategy method in ultimatum bargaining, many researchers ask responders for the minimal acceptable offer only implicitly assuming strategies to be monotone. Recent research has shown, however, that subjects decline disadvantageous and advantageous proposals. We report on an...

The paper reports simulations applied on two similar congestion games: the first is the classical minority game. The second one is a asymmetric variation of the minority game with linear payoff functions. For each game simulation results based on an extended reinforcement algorithm are compared...

We use an experiment to explore how subjects learn to play against computers which are programmed to follow one of a number of standard learning algorithms. The learning theories are (unbeknown to subjects) a best response process, fictitious play, imitation, reinforcement learning, and a trial...

We study a public goods game where subjects get feedback either continually or intermittently. We find that the intermittent feedback helps to mitigate problems of free riding because subjects in this treatment focus more on a string of choices rather than deciding on a case by case basis as in...
