Facets of Proportionality: Selecting Committees, Budgets, and Clusters
Abstract: Proportionality is a key concept in computational social choice: if we make a collective decision, this decision should reflect every group of agents taking part in the decision-making proportionally. But what does “proportionally” mean exactly? How can we define it and which definitions are meaningful? I will try to answer these questions by giving an overview of my thesis dealing with proportionality in the contexts of multiwinner voting, participatory budgeting, and clustering.
