Optimal payoffs under state-dependent preferences

State-Dependent Preferences

Pareto Optimal Allocation under Uncertain Preferences

The assignment problem is one of the most wellstudied settings in social choice, matching, and discrete allocation. We consider this problem with the additional feature that agents’ preferences involve uncertainty. The setting with uncertainty leads to a number of interesting questions including the following ones. How to compute an assignment with the highest probability of being Pareto optima...

Optimal Reallocation under Additive and Ordinal Preferences

Reallocating resources to get mutually beneficial outcomes is a fundamental problem in various multi-agent settings. In the first part of the paper we focus on the setting in which agents express additive cardinal utilities over objects. We present computational hardness results as well as polynomial-time algorithms for testing Pareto optimality under different restrictions such as two utility ...

Approximating Optimal Social Choice under Metric Preferences

We examine the quality of social choice mechanisms using a utilitarian view, in which all of the agents have costs for each of the possible alternatives. While these underlying costs determine what the optimal alternative is, they may be unknown to the social choice mechanism; instead the mechanism must decide on a good alternative based only on the ordinal preferences of the agents which are i...
