What is Coalizer?
Coalizer is a coalition formation analysis tool that reflects the state of coalition theory by taking both the office and the policy motivations of political parties into account. Basing on parties’ seat distributions and their policy positions, Coalizer computes their expected office and policy utility values in different coalitions. Additionally, Coalizer identifies utility maximizing alternatives for parties and searches for coalitions which are in equilibrium.
