Table 1_B-Call: integrating ideological position and voting cohesion in legislative behavior.docx

This paper addresses two central dimensions of legislative behavior: ideological position and voting cohesion. Although both approaches have been widely used to analyze legislative behavior, no unified model currently integrates these dimensions. To fill this gap, the paper proposes a methodology called B-Call, which combines both dimensions by treating votes as random variables. The model is empirically validated using roll-call data from the legislatures of the United States, Brazil, and Chile. The analysis seeks to capture the complexities of voting behavior, resulting in a two-dimensional indicator. This study addresses key gaps in existing legislative voting models, particularly in contexts with limited party control.

本研究聚焦立法行为的两大核心维度：意识形态立场与投票凝聚力。尽管这两类研究路径均已广泛应用于立法行为分析，但目前尚无统一模型能够整合这两大维度。为填补这一研究空白，本研究提出一种名为B-Call的分析方法，该方法将投票视为随机变量，从而整合上述两大维度。该模型通过美国、巴西与智利三国议会的点名投票数据完成实证验证。本分析旨在刻画投票行为的复杂面向，最终得到一项二维综合指标。本研究填补了现有立法投票模型的关键研究空白，尤其适用于政党管控能力有限的议会场景。
