Abstract

We study the allocation of collectively owned indivisible goods when monetary transfers are possible. We restrict our attention to incentive-compatible mechanisms which allocate the goods efficiently. Among these mechanisms, we characterize those that respect the identical preferences lower bound: each agent should be at least as well off as in a hypothetical economy where all agents have the same preference as hers, no agent envies another, and the budget is balanced.
