• On the constrained efficiency of strategy-proof random assignment 

    Basteck, Christian; Ehlers, Lars (Université de Montréal. Département de sciences économiques., 2023-04-25)
    We study random assignment of indivisible objects among a set of agents with strict preferences. Random Serial Dictatorship is known to be only ex-post efficient and there exist mechanisms which Pareto-dominate it ex-ante. However, we show that there ...
  • Strategy-proof and envyfree random assignment

    We study the random assignment of indivisible objects among a set of agents with strict preferences. We show that there exists no mechanism which is strategy-proof, envyfree and unanimous. Then we weaken the latter requirement to q-unanimity: when ...
