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...

Social networks are a key factor of success in life, but they are also strongly segmented on gender, ethnicity, and other demographic characteristics (Jackson, 2010). We present novel evidence on an understudied source of homophily: behavioral traits. Behavioral traits are important determinants...

This paper theoretically investigates how labor-market tightness affects market outcomes if firms use informal and self-enforcing agreements to motivate workers. We characterize profit-maximizing equilibria and derive the following results. First, an increase in the supply of homogenous workers...

We investigate overlapping contests in multi-divisional organizations in which an individual's effort simultaneously determines the outcome of several contests on different hierarchical levels. We show that individuals in smaller units are advantaged in the grand (organization-wide) contest for...

We study the relationship between outside options and workers’ motivation to exert effort. We evaluate changes in outside options arising from age and experience cutoffs in the Austrian unemployment insurance (UI) system, and use absenteeism as a proxy for worker effort. Results indicate that...

Economic theory suggests that the deterrence of deviant behavior is driven by a combination of severity and certainty of punishment. This paper presents the first controlled experiment to study a third important factor that has been mainly overlooked: the swiftness of formal sanctions. We...

The effectiveness of social interaction depends strongly on an ability to coordinate actions efficiently. In large networks, such coordination may be very difficult to achieve and may depend on the communication technology and the network structure. We examine how pre-play communication and...

Many important intertemporal decisions, such as investments of firms or households, are made by groups rather than individuals. Little is known what happens to such collective decisions when group members have different incentives for waiting, because the economics literature on group decision...

Research examining the effect of weak punishment on conformity indicates that punishment can backfire and lead to suboptimal social outcomes. We examine whether this effect is due to a lack of perceived legitimacy of rule enforcement, which would enable agents to justify selfish behavior. We...

We present direct evidence on the link between children’s patience and educational-track choices years later. Combining an incentivized patience measure of 493 primary-school children with their high-school track choices taken at least three years later at the end of middle school, we find...
