Collaborative Research: Issues and Economics in Multiparty Democracies

这项合作调查使用新的创新离散选择模型，研究了先进工业民主国家基于问题和基于经济的投票的程度。这项研究既有实质性的组成部分，也有方法论的组成部分。调查人员使用了一种综合的投票选择模型，这使得他们能够研究八个国家中以问题和经济为导向的投票的程度。该模型还允许调查政党在问题空间中的运动，将政党从选举竞争中除名，以及选举经济背景的变化。在方法论上，研究人员采用了政治研究中新出现的一种重要的离散选择模型。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完成的，这些模型对多党制下的选民如何在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的替代假设的独立性。他们的模型，在这个项目中，没有把这个假设强加给选民，它也提供了一种非常灵活的方式来对多党选举进行经验性的建模。这一项目将大大增进我们对这一专题的理解，并将为有关这一专题的方法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.
