Control in Judgment Aggregation

Dorothea Baumeister, Gábor Erdélyi, Olivia Johanna Erdélyi, Jörg Rothe

Abstract: In computational social choice, the complexity of changing the outcome of elections via various control actions, such as adding or deleting candidates or voters, has been studied intensely. We introduce the concept of control for judgment aggregation procedures, and study the complexity of changing the outcome of such procedures via control by adding, deleting, or replacing judges.
