Credence goods markets suffer from inefficiencies caused by superior information of sellers about the surplus-maximizing quality. While standard theory predicts that equal mark-up prices solve the credence goods problem if customers can verify the quality received, experimental evidence...

Entry decisions in market entry games usually depend on the belief about how many others are entering the market, the belief about the own rank in a real effort task, and subjects' risk preferences. In this paper I am able to replicate these basic results and examine two further dimensions: (i)...

Informational asymmetries abound in economic decision making and often provide an incentive for deception through telling a lie or misrepresenting information. In this paper I use a cheap-talk sender-receiver experiment to show that telling the truth should be classified as deception too if the...

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 study whether information about imminent future dividends can abate bubbles in experimental asset markets. Using the seminal design of Smith et al. (1988) we find that markets where traders are asymmetrically informed about future dividends have smaller, and shorter, bubbles than markets with...

Credence goods, such as car repairs or medical services, are characterized by severe informational asymmetries between sellers and consumers, leading to fraud in the form of provision of insufficient service (undertreatment), provision of unnecessary service (overtreatment) and charging too much...

Credence goods markets are characterized by asymmetric information concerning the needed and/or provided quality between experts and consumers. The functioning of the market heavily relies on trust on the side of the consumer as well as trustworthiness on the side of the expert. However, a great...

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 compare the behavior of car mechanics and college students as sellers in experimental credence goods markets. Finding largely similar behavior, we note much more overtreatment by car mechanics, probably due to decision heuristics they learned in their professional training. -- artefactual...

Credence goods markets are prone to fraudulent behavior and market inefficiencies due to informational asymmetries between sellers and customers. We examine experimentally the effects of diagnostic uncertainty and insurance coverage on the information acquisition and provision decisions by...
