Join Christian Basteck as they present their research on Strategy-proof and Envy-free Random Assignment
Christian Basteck, from WZB Berlin Social Science Center, will present their research on Strategy-proof and Envy-free Random Assignment by Christian Basteck.
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 unanimous, strategy-proof and envy-free. Weakening the first requirement to q-unanimity – i.e., when every agent ranks a different object at the top, then each agent shall receive his most-preferred object with probability of at least q – we show that a mechanism satisfying strategy-proofness, envy-freeness and ex-post weak non-wastefulness can be q-unanimous only for q ≤ 2/n (where n is the number of agents). To demonstrate that this bound is tight, we introduce a new mechanism, Random-Dictatorship-cum-Equal-
