Collaborative Research: Issues and Economics in Multiparty Democracies

这项合作调查研究的程度，基于问题和经济为基础的投票在先进的工业民主国家使用新的创新离散选择模型。 这项研究既有实质性内容，也有方法性内容。 调查人员采用了一个综合的投票选择模型，使他们能够研究在一组八个国家的问题和经济导向的投票程度。 该模型还允许调查政党在问题空间中的运动，从选举竞争中去除政党，以及选举经济背景的变化。 在方法论上，研究人员采用了一个重要的离散选择模型新的政治研究。 研究人员认为，过去关于多党制民主国家选民选择的工作是使用统计模型进行的，这些模型对选民如何在多党制中的政党之间做出决定施加了非常严格的假设。 特别值得关注的是不相关替代假设的独立性。 对于这个项目，他们的模型并没有把这个假设强加给选民，而且它还提供了一种非常灵活的方法来模拟多党选举。 该项目将大大提高我们对这一主题的理解，并将为关于这一主题的方法论和理论辩论提供信息。

This collaborative investigation researches the extent of issue-based and economic-based voting in advanced industrial democracies using new innovative discrete choice models. The research has both substantive and methodological components. The investigators employ an integrated model of vote choice which allows them to study the degree of issue- and economic-oriented voting in a set of eight nations. The model also allows investigation of the movement of political parties in issue space, the removal of parties from electoral competition, and changes in the economic context of the election. Methodologically the investigators employ an important discrete choice model new to political research. The researchers argue that past work on voter choice in multiparty democracies has been done using statistical models which impose very restrictive assumptions on how voters make their decisions amongst parties in multiparty systems. Of particular concern is the independence of irrelevant alternatives assumption. Their model, for this project, does not impose this assumption on voters, and it also provides a very flexible way to model multiparty elections empirically. This project will substantially enhance our understanding of the topic and will inform the methodological and theoretical debate about it.
