We study the economic consequences of opportunities for dishonesty in an environment where efficiency relevant behaviour is not contractible, but rather incentivized by informal agreements in an ongoing relationship. We document the repeated interaction between a principal and an agent who,...

What is the strategic role of membership in an intergovernmental group with unanimity requirements if the group negotiates with an external player in a setting with incomplete information? Being in such a group has a strategic effect compared to negotiating as a standalone player and reduces the...

We study an infinitely repeated principal-agent relationship with on-the-job search. On-the-job search is modeled as a dimension of the agent's effort vector that has no effect on output, but raises his future outside option. The agent's incentives to search are increasing in the degree to which...

Using non-cooperative game theory the effects of mediation on the divorce rate and on the utility of the spouses are analysed. Two kinds of mediation are considered: restricted mediation that reduces the costs of divorce and extended mediation that additionally may prevent divorces by...

We consider a co-evolutionary model of social coordination and network formation where agents may decide on an action in a 2x2 - coordination game and on whom to establish costly links to. We find that a payoff dominant convention is selected for a wider parameter range when agents may only...

This paper analyzes a two-player all-pay auction with incomplete information. More precisely, one bidder is uncertain about the size of the initial advantage of his rival modeled as a head start in the auction. I derive the unique Bayesian Nash equilibrium outcome for a large class of cumulative...

Can fiscal policy raise utility for all in dynamic economies with unobservable agent heterogeneity, when missing credit and insurance markets affect incentives to invest in human capital? If so, should the state provide transfers to the poor in the form of cash or in kind? In an occupational...

This paper introduces a class of contest models in which each player decides when to stop a privately observed Brownian motion with drift and incurs costs depending on his stopping time. The player who stops his process at the highest value wins a prize. We prove existence and uniqueness of a...

Motivated by trying to better understand the norms that govern pedestrian traffic, I study symmetric two-player coordination games with independent private values. The strategies of "always pass on the left" and "always pass on the right" are always equilibria of this game. Some such games,...
