Replication Data for: Open/Closed List and Party Choice: Experimental Evidence from the U.K.

Replication Data for: Blumenau, Eggers, Hangartner and Hix: Open/Closed List and Party Choice: Experimental Evidence from the U.K. Abstract: Which parties benefit from open-list (as opposed to closed-list) PR elections? We show that a move from closed-list to open-list competition is likely to be more favorable to parties with more internal disagreement on salient issues; this is because voters who might have voted for a unified party under closed lists may be drawn to specific candidates within internally divided parties under open lists. We provide experimental evidence of this phenomenon in a hypo- thetical European Parliament election in the UK, in which using an open-list ballot would shift support from UKIP (the Eurosceptic party) to Eurosceptic candidates of the Conservative Party. Our findings suggest that open-list ballots could restrict support for parties that primarily mobilize on a single issue.

复现数据集：布劳瑙（Blumenau）、埃格斯（Eggers）、汉加特纳（Hangartner）与希克斯（Hix）：《开放名单与政党选择：来自英国的实验证据》
摘要：哪些政党会从开放名单制（相较于封闭名单制）比例代表制（Proportional Representation, PR）选举中获益？本研究表明，从封闭名单制转向开放名单制的竞争格局，更有利于那些在核心议题上存在较多内部分歧的政党。这是因为在封闭名单制下原本会投票给团结统一政党的选民，在开放名单制下可能会转而支持内部分歧政党内部的特定候选人。我们通过英国假想欧洲议会选举的实验证据验证了这一现象：在该实验中，采用开放名单制选票会将支持票从英国独立党（UK Independence Party, UKIP）转向保守党旗下的疑欧主义候选人。本研究结果显示，开放名单制选票可能会削弱那些主要依靠单议题进行动员的政党的支持基础。
