Envy Cycle Elimination with Strategic Agents: Best Responses and Fairness Guarantees
Georgios Amanatidis, Georgios Birmpas, Rebecca Reiffenhäuser
With strong evidence in the literature showing that fairness and truthfulness are incompatible, there is a recent line of work focusing on the fairness properties of equilibria of…
Position Auctions with a Capacity Constraint
Eleni Batziou, Georgios Birmpas, Georgios Chionas +1
Sponsored search auctions are commonly modeled as an assignment of a fixed set of slots (positions) to a set of advertisers, with welfare maximization being reducible to a standard…
Reward Schemes and Committee Sizes in Proof of Stake Governance
Georgios Birmpas, Philip Lazos, Evangelos Markakis +1
In this paper, we investigate the impact of reward schemes and committee sizes motivated by governance systems over blockchain communities. We introduce a model for elections with…
Algorithmically Fair Maximization of Multiple Submodular Objective Functions and Implications to Constrained Fair Division
Georgios Amanatidis, Georgios Birmpas, Philip Lazos +2
Constrained maximization of submodular functions is a central problem in combinatorial optimization. In many realistic scenarios, multiple agents each need to maximize their own su…
Fair Division with Interdependent Values
Georgios Birmpas, Tomer Ezra, Stefano Leonardi +1
We introduce the study of designing allocation mechanisms for fairly allocating indivisible goods in settings with interdependent valuation functions. In our setting, there is a se…
Round-Robin Beyond Additive Agents: Existence and Fairness of Approximate Equilibria
Georgios Amanatidis, Georgios Birmpas, Philip Lazos +2
Fair allocation of indivisible goods has attracted extensive attention over the last two decades, yielding numerous elegant algorithmic results and producing challenging open quest…
