Interactions between players with private information and opposed interests are often prone to bad advice and inefficient outcomes, e.g. markets for financial or health care services. In a deception game we investigate experimentally which factors could improve advice quality. Besides advisor...

An advisor is supposed to recommend a financial product in the best interest of her client. However, the best product for the client may not always be the product yielding the highest commission to the advisor. Do advisors nevertheless provide truthful advice? If not, will a voluntary or...

The market for retail financial products (e.g. investment funds or insurance) is marred by information asymmetries. Clients are not well informed about the quality of these products. They have to rely on the recommendations of advisors. Incentives of advisors and clients may not be aligned, when...

Credence goods are characterized by informational asymmetries between sellers and consumers that invite fraudulent behavior by sellers. This paper presents the results of a natural field experiment on taxi rides in Athens, Greece, set up to measure different types of fraud and to examine the...

Empirical literature on moral hazard focuses exclusively on the direct impact of asymmetric information on market outcomes, thus ignoring possible repercussions. We present a field experiment in which we consider a phenomenon that we call second-degree moral hazard - the tendency of the supply...
