Social Choice Theory

Social choice theory addresses the methods and processes of collective decision making. Applications range from preference aggregation in small committees, voting in democratic elections at the regional and national level to questions of fair resolution of conflicting interests. Important properties of aggregation methods are, for instance, anonymity, unanimity, efficiency, monotonicity and strategy-proofness (incentive compatibility). Our research is devoted to the identification and design of aggregation methods that combine such properties.
