This paper establishes the existence of relaxed solutions to mean eld games (MFGs for short) with singular controls. As a by-product, we obtain an existence of relaxed solutions results for McKean-Vlasov stochastic singular control problems. Finally, we prove approximations of solutions results...

From the regulation of sports to lawmaking in parliament, in many situations one group of people ("agents") makes decisions that affect payoffs of others ("principals") who are inactive. As the principals have a stake in the agents' decisions they face an incentive to offer payments in order to...

We study preferences over procedures in the presence of naive agents. We employ a school choice setting following Pathak and Sönmez (2008) who show that sophisticated agents are better off under the Boston mechanism than under a strategy-proof mechanism if some agents are sincere. We use lab...

From the regulation of sports to lawmaking in parliament, in many situations one group of people ("agents") make decisions that affect the payoffs of others ("principals") who may offer action-contingent transfers in order to sway the agents' decisions. Prat and Rustichini (2003) characterize...

This paper studies how information control affects incentives for collusion and optimal organizational structures in principal-supervisor-agent relationships. I consider a model in which the principal designs the supervisor's signal on the productive agent's private information and the...

Proxy wars are a key pattern of political conflict and interstate competition. Rather than resorting to direct conflicts, which are costly and entail a higher level of uncertainty, governments may opt for proxy wars, which may last longer, but are less costly and render them more immune to...

We consider a single object allocation problem with multidimensional signals and interdependent valuations. When agents' signals are statistically independent, Jehiel and Moldovanu [Efficient design with interdependent valuations, Econometrica, 69(5):1237-1259, 2001] show that efficient and...
