In an experiment on the repeated prisoner s dilemma where intended actions are implemented with noise, Fudenberg et al. (2012) observe that non-equilibrium strategies of the "tit-for-tat" family are largely adopted. Furthermore, they do not find support for risk dominance of TFT as a determinant...

This paper presents an experiment on learning in repeated games, which complements the analysis of players' actual choices with data on the information acquisition process they follow. Subjects play a repeated Cournot oligopoly, with limited a priori information. The econometrics hinges on a...

Credence goods markets suffer from inefficiencies arising from informational asymmetries between expert sellers and customers. While standard theory predicts that inefficiencies disappear if customers can verify the quality received, verifiability fails to yield efficiency in experiments with...

Credence goods markets are characterized by asymmetric information between sellers and consumers that may give rise to inefficiencies, such as under- and overtreatment or market break-down. We study in a large experiment with 936 participants the determinants for efficiency in credence goods...

We experimentally examine the impact of tax evasion attempts on the performance of credence goods markets, where contractual incompleteness results from asymmetric information on the welfare maximizing quality of the good. Our results suggest that tax evasion attempts – independently of...

We examine the influence of guilt and trust on the performance of credence goods markets. An expert can make a promise to a consumer first, whereupon the consumer can express her trust by paying an interaction price before the expert's provision and charging decisions. We argue that the expert's...

Credence goods markets – like for health care or repair services – with their informational asymmetries between sellers and customers are prone to fraudulent behavior of sellers and resulting market inefficiencies. We present the first model that considers both diagnostic uncertainty of...

Economic inequality may fuel frustration, possibly leading to anger and antisocial behavior. We experimentally study a situation where only the rich can reduce inequality while the poor can express their discontent by destroying the wealth of a rich counterpart with whom they had no previous...
