In this paper, we model networks of relational contracts. We explore sanctioning power within these networks under different information technologies depending on the shape of the network. The value of the relational network lies in the enforcement of cooperative agreements which would not be...

The paper shows that fighting corruption with leniency programs -- reductions of the legal sanctions for wrongdoers who spontaneously report to law enforcers -- may be highly counterproductive. These programs are typically ``moderate,'' in the sense of only reducing, or at best cancelling the...

We study an elimination tournament with heterogenous contestants whose ability is common-knowledge. Each pair-wise match is modeled as an all-pay auction where the winner gets the right to compete at the next round. Equilibrium efforts are in mixed strategies, yielding rather complex play...
