SUMMARY:Robust and Frugal Mechanisms for Hiring a Team - Mahyar Salek (MSR

DESCRIPTION:Project sourcing is becoming increasingly difficult due to the
  growing volume and complexity of modern projects. Projects often require 
 a team of agents with diverse skills. In addition\, it is sometimes too ex
 pensive to evaluate the performance of an agent (Compare the cost of verif
 ying an annotation for a photo to annotating it). \n\nWe consider two appr
 oaches for hiring a team: auctions and crowdsourcing. For auctions\, we sh
 ow how to design truthful and frugal auctions for a broad class of set sys
 tems. Our mechanism is built on the spectral properties of a graph reduced
  from the set system. For crowdsourcing\, we study truthful peer predictio
 n mechanism.
