Smart Lotteries in School Choice: Ex-ante Pareto-Improvement with Ex-post Stability
Haris Aziz, Péter Biró, Gergely Csáji +1
In school choice, students typically have strict preferences over the schools while the schools have coarse priorities over the students based on their distance and their enrolled…
Pairwise efficiency and monotonicity imply Pareto efficiency in (probabilistic) object allocation
Tom Demeulemeester, Bettina Klaus
We consider object allocation problems with capacities where objects have to be assigned to agents. We show that a probabilistically monotonic lottery rule satisfies ex-post Pareto…
Quantifying Core Stability Relaxations in Hedonic Games
Tom Demeulemeester, Jannik Peters
We study relationships between different relaxed notions of core stability in hedonic games, which are a class of coalition formation games. Our unified approach applies to a newly…
Fair integer programming under dichotomous and cardinal preferences
Tom Demeulemeester, Dries Goossens, Ben Hermans +1
One cannot make truly fair decisions using integer linear programs unless one controls the selection probabilities of the (possibly many) optimal solutions. For this purpose, we pr…
Strategyproofness and Proportionality in Party-Approval Multiwinner Elections
Théo Delemazure, Tom Demeulemeester, Manuel Eberl +2
In party-approval multiwinner elections the goal is to allocate the seats of a fixed-size committee to parties based on the approval ballots of the voters over the parties. In part…
Rawlsian Assignments
Tom Demeulemeester, Juan S. Pereyra
We study the assignment of indivisible goods to individuals without monetary transfers. Existing literature has mainly focused on efficiency and individually fair assignments; cons…
A pessimist's approach to one-sided matching
Tom Demeulemeester, Dries Goossens, Ben Hermans +1
Inspired by real-world applications such as the assignment of pupils to schools or the allocation of social housing, the one-sided matching problem studies how a set of agents can…
