Representation, Stability and Diversity in Group Decision-making

Abstract

In this talk, I will discuss issues that arise when agents with diverse preferences and attributes need to form groups and elect representative bodies. In the context of group formation, I will talk about my recent work on hedonic games with diversity preferences, where agents have preferences over how diverse their groups are. This work is closely connected to Schelling's study of racial segregation, and I will also mention the game-theoretic model we have recently developed for this setting. In the context of elections, I will survey the work on the justified representation axiom and its variants, as well as the rules that satisfy it.
