Are commonly known beliefs essential for bidding behavior in asymmetric auctions? Our experimental results suggest that not informing participants how values are randomly generated does not change behavior much and may even make it appear more rational.

This thesis contributes to the research on other regarding preferences by experimental studies. Chapter 1 investigates the feasibility of efficiency gains in a principal-agent relationship by voluntary leadership. Chapter 2 investigates whether negative reciprocity can be documented if the worse...

In this experimental study we analyze one individual and three collective punishment rules in a public good setting. We present evidence and explanations for differences between the rules concerning punishment intensity, contribution and profit levels, as well as justice. Finally, we investigate...

We present a striking example of the deconstruction and reconstruction of an anomaly. In line with previous experiments we show in a one-shot setting that the allegedly robust false consensus effect disappears if representative information is readily available. But the effect reappears if a...

We study two person-betting games with inconsistent commonly know beliefs, using an experimentalapproach. In our experimental games, participants bet against one another, each bettorchoosing one of two possible outcomes, and payoff odds are know at the time bets are placed.Bettors’ beliefs are...

Unlike previous attempts to implement cooperation in a prisoners’ dilemma gamewith an infinite horizon in the laboratory, we focus on extended prisoners’ dilemmagames in which a second (pure strategy) equilibrium allows for voluntary cooperationin all but the last round. Our four main...

We study interaction effects between intra-firm conflicts and interfirm competitionon a duopolistic market with seller firms employing one or more agents and imple-menting tournament incentives. We show that inter-firm competition leads to higherincentive intensity, higher efforts and output...

We experimentally investigate how affective processes influence proposers’and responders’ behaviour in the Ultimatum Game. Using a dualsystemapproach, we tax cognitive resources through time pressure andcognitive load to enhance the influence of affective processes on behaviour.We find that...

Using a symmetric 2-person prisoners’ dilemma as the base game, each playerreceives a signal for the number of rounds to be played with the same partner.The actual number of rounds (the length of the supergame) is determined bythe maximal signal where each player expects the other’s signal...

We report on an experiment designed to explore whether allowing individualsto voice their anger prevents costly punishment. For this sake, weuse an ultimatum minigame and distinguish two treatments: one in whichresponders can only accept or reject the o®er, and the other in which theycan also...
