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...

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...

We devise a new experimental game by nesting a voluntary contributions mechanism in a broader spectrum of incentive schemes. With it, we study tensions between egalitarianism, equity concerns, self-interest, and the need for incentives. In a 2x2 design, subjects eithervote on or exogenously...

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 whether...

We study experimentally the protection of property in five widely distinct countries - Austria, Mexico, Mongolia, South Korea and the United States. Our main results are that the security of property varies with experimental institutions, and that our subject pools exhibit significantly...

Evidence on behavior of experts in credence goods markets raises an important causality issue: Do "fair prices" induce "good behavior", or do "good experts" post "fair prices"? To answer this question we propose and test a model with three seller types: "the good" choose fair prices and behave...

We study experimentally the protection of property in five widely distinct countries - Austria, Mexico, Mongolia, South Korea and the United States. Our main results are that the security of property varies with experimental institutions, and that our subject pools exhibit significantly...

Building on a theoretical model we test the hypothesis that effort choices and preferences for redistribution are simultaneously determined. Using cross-country panel data from the World Value Survey, we find that it is important to model preferences for redistribution and effort choices...

We measure the willingness to compete of entrepreneurs and salaried workers in an experiment. We let participants choose between a piece-rate and a tournament scheme either in private or in public. We find that in the private condition entrepreneurs are less competitive than salaried workers,...

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...
