Strategy-proof, budget-balanced, and envy-free rank mechanisms assign q identical objects to n agents. The efficiency loss is the largest ratio of surplus loss to efficient surplus, over all profiles of non-zero valuations. The smallest efficiency loss (n−q)/(n^2−n) is uniquely achieved by the following simple allocation rule: assign one object to each of the q − 1 agents with the highest valuations, a large probability to the agent with the qth highest valuation, and the remaining probability to the agent with the (q + 1)th highest valuation.
[Seminar] Random Mechanism Design
on Multidimensional Domains.

Abstract: We study random mechanism design
in an environment where the set of alternatives has a Cartesian product structure. We
first show that all generalized random dictatorships are strategy-proof on a minimally
rich domain if and only if the domain is a top-separable domain. We next generalize the
notion of connectedness (Monjardet, 2009) to establish a particular class of top-separable
domains: connected+ domains, and show that in the class of minimally rich and connected+
domains, the multidimensional single-peakedness restriction is necessary and sufficient for
the design of a flexible random social choice function that is unanimous and strategy-proof. Such
a flexible function is distinct from generalized random dictatorships in that it allows
for a systematic notion of compromise. Our characterization remain…
