Center node: "mechanism design with execution uncertainty"
  Abstract: We introduce the notion of fault tolerant mechanism design, which extends the standard game theoretic framework of mechanism design to allow for uncertainty about execution. Specifically, we define the problem of task allocation in which the private information of the agents is not only their costs to attempt the tasks, but also their probabilities of failure. For several different instances of this setting we present technical results, including positive ones in the form of mechanisms that are incentive compatible, individually rational and efficient, and negative ones in the form of impossibility theorems.

Connected through hyperedge HE-1 (induced by source paper "trust based mechanisms for robust and efficient task allocation in the presence of execution uncertainty"):
  with members:
    - "obtaining reliable feedback for sanctioning reputation mechanisms"
    - "computationally feasible vcg mechanisms"

Connected through hyperedge HE-2 (induced by source paper "computationally feasible vcg mechanisms"):
  with members:
    - "bundling equilibrium in combinatorial auctions"
    - "truth revelation in approximately efficient combinatorial auctions"
