Arguing that consumers are the carriers of firms’ reputations, we examine the role of consumer networks for trust in markets that suffer from moral hazard. When consumers are embedded in a network, they can exchange information with their neighbours about their private experiences with...

We study experimentally a standard four-player Hotelling location game with a uniform density of consumers and inelastic demand. The pure strategy Nash equilibrium configuration consists of two firms located at one quarter of the "linear city, " and the other two at three quarters. We do not...

Consider a committee that in the past has made a promise not to confiscate the profits from an investor. After the investment has taken place, there is a material benefit if the committee decides to default on the earlier promise. But in some situations there are also some small moral costs for...

We study the mechanics of leading by example in teams. Leadership is beneficial for the entire team when agents are conformists, i.e., dislike effort differentials. We also show how leadership can arise endogenously and discuss what type of leader benefits a team most.

Lars von Trier's movie 'Dogville' illustrates some illuminating and poignant comparative statics of equilibrium allocations, according to Heike Harmgart and Steffen Huck.

Most contracts, whether between voters and politicians or between house owners and contractors, are incomplete. "More law," it typically is assumed, increases the likelihood of contract performance by increasing the probability of enforcement and/or the cost of breach. This paper studies a...

We introduce a generalized theoretical approach to study imitation models and subject the models to rigorous experimental testing. In our theoretical analysis we find that the different predictions of previous imitation models are due to different informational assumptions, not to different...

Merged firms are typically rather complex organizations. Accordingly, merger has a more profound effect on the structure of a market than simply reducing the number of competitors. We show that this may render horizontal mergers profitable and welfare-improving even if costs are linear. The...
