ABSTRACT

While prior work on coalition theories focuses either solely on office or on policy motivations of parties, more elaborate theories combine both types of motivation. Said combination makes them much more appropriate for explaining coalition formation but also more complex. One possibility to make these models broadly applicable are coalition tools. Since existing tools do not incorporate advances from such theories, we present a new coalition tool called Coalizer which takes both office and policy motivations into account and reflects the state of coalition theory. Among others, Coalizer includes features like the computation of policy utility values basing on party positions (supporting different estimation modes), the combination of office and policy utility values, and the indication of utility maximizing strategies for parties. In this paper, we present our coalition tool and illustrate its functionality with the example of the German federal elections in 2017. Coalizer is available online at www.mytuc.org/mcbz

摘要

虽然先前关于联盟理论的工作只关注政党的执政动机或政策动机，但更复杂的理论结合了这两种类型的动机。这种组合使它们更适合解释联盟的形成，但也更复杂。使这些模型广泛适用的一种可能性是联盟工具。由于现有工具没有结合这些理论的进步，我们提出了一种称为 Coalizer 的新联盟工具，它同时考虑了办公室和政策动机，并反映了联盟理论的状态。其中Coalizer包括基于政党立场的政策效用值计算（支持不同的估计模式），办公室和政策效用值的结合，以及政党效用最大化策略的指示等功能。在本文中，
