立法者为什么以及何时一起投票决定政策？立法者决定以类似的方式投票，主要是因为社会影响还是相似？我通过提供投票的社会网络理论来贡献文献。有人认为，密切的社会联系有助于建立声誉，并帮助同行立法者之间的信息流动，从而增加影响力和增加他们之间的共同投票率。我检查的信息交换网络和社会交换网络的共同投票率的相对影响，控制立法者之间的相似性。数据包括2010年至2014年巴西众议院的立法投票。研究结果表明，社会关系产生的社会影响力对国会共同投票率产生重大影响。
Why and when do legislators vote together on policy? Do legislators decide to vote similarly mainly because of social influence or similarity? I contribute to the literature by offering a social network theory of voting. It is argued that close social ties help to establish reputations and to aid the flow of information among peer legislators, leading to increased influence and increased rates of co-voting among them. I examine the relative effects of information exchange networks and social exchange networks on rates of co-voting, controlling for similarities among legislators. The data include legislative votes from 2010 to 2014 in the Brazilian Chamber of Deputies. The results suggest that social influence stemming from social relationships exert substantial effects on rates of congressional co-voting.
