Multi-unit assignment under dichotomous preferences

摘要

I study the problem of allocating objects among agents without using money. Agents can receive several objects and have dichotomous preferences, meaning that they either consider objects to be acceptable or not. In this set-up, the egalitarian solution is more appealing than the competitive equilibrium with equal incomes because it is Lorenz dominant, unique in utilities, and group strategy-proof. Both solutions are disjoint. Crown Copyright (C) 2019 Published by Elsevier B.V. All rights reserved.
