Collaborative Research on Political Choice Data

这项研究针对的是政治选择数据，主要是立法机构的唱名投票。它侧重于唱名表决的三个不同组成部分。第一部分研究大众精英重新排列的动态。它解决了国会投票行为的变化是否受到草根积极分子的刺激的问题。第二部分侧重于个人层面点名投票行为的动态变化。它解决的问题是，立法者在进入国会之前是否确定了他们的意识形态立场，或者他们的立场是否随着时间的推移而演变。第三部分开发了估计立法者动力的新方法。

This research is directed at political choice data, primarily roll call votes in legislatures. It focuses on three distinct components of roll call voting. The first component studies the dynamics of mass-elite realignments. It addresses the question of whether changes in congressional voting behavior are stimulated by grass roots activists. The second component focuses on the dynamics of change in individual level roll call voting behavior. It addresses the question of whether legislators fix their ideological positions prior to entering Congress or whether their positions evolve over time. The third component develops new methods for estimating legislator dynamics.
