Replication data for: Institutional Context, Cognitive Resources and Party Attachments Across Democracies

This paper develops and tests arguments about how national-level social and institutional factors shape the propensity of individuals to form attachments to political parties. Our tests employ a two-step estimation procedure that has attractive properties when there is a binary dependent variable in the first stage and when the number of second-level units is relatively small. We find that voters are most likely to form party attachments when group identities are salient and complimentary. We also find that institutions that assist voters in retrospectively evaluating parties—specifically, strong party discipline and few parties in government—increase partisanship. These institutions matter most for those individuals with the fewest cognitive resources, measured here by education. Supplementary data available here

本研究构建并检验了国家级社会与制度因素如何塑造个体形成政党依附倾向的理论命题。我们的检验采用两步估计法，该方法在第一阶段存在二元因变量且第二层级单元数量相对较少时具备优良特性。研究发现，当群体身份凸显且相互兼容时，选民最易形成政党依附。同时我们还发现，能够帮助选民回溯性评估政党的制度——具体而言即严格的政党纪律与较少的执政党派数量——会增强选民的党派认同。此类制度对以受教育程度衡量的认知资源最少的个体影响最为显著。补充数据可在此处获取。
