摘要翻译：
政治竞选是美国最复杂的营销活动之一。作为营销传播策略的一部分，越来越多的政治家采用社交媒体来通知他们的选民。这项研究通过关注获得的竞选捐款的变化，记录了竞选国会的政治家采用新技术即推特的回报。我们比较了在推特渗透率高和低的地区，政治家开设推特账户之前和之后收到的每周捐款，控制了政治家月的固定影响。具体地说，在政治竞选过程中，我们估计，在推特渗透率高和低的地区开设推特账户的差异影响相当于所有政治家的捐款增加0.7-2%，新政治家的捐款增加1-3.1%，他们以前从未当选国会议员。相比之下，对经验丰富的政治家来说，加入Twitter的影响仍然微乎其微。我们发现一些证据与这种效应是由候选人的新信息驱动的解释相一致，例如，这种效应主要是由新捐赠者而不是过去的捐赠者、没有脸书账户的候选人和更多信息的推特驱动的。总的来说，我们的发现表明，社交媒体可以通过降低新进入者向其选民传播信息的成本来加剧政治竞争，从而可能减少进入政治的障碍。

英文摘要：
  Political campaigns are among the most sophisticated marketing exercises in the United States. As part of their marketing communication strategy, an increasing number of politicians adopt social media to inform their constituencies. This study documents the returns from adopting a new technology, namely Twitter, for politicians running for Congress by focusing on the change in campaign contributions received. We compare weekly donations received just before and just after a politician opens a Twitter account in regions with high and low levels of Twitter penetration, controlling for politician-month fixed effects. Specifically, over the course of a political campaign, we estimate that the differential effect of opening a Twitter account in regions with high vs low levels of Twitter penetration amounts to an increase of 0.7-2% in donations for all politicians and 1-3.1% for new politicians, who were never elected to the Congress before. In contrast, the effect of joining Twitter for experienced politicians remains negligibly small. We find some evidence consistent with the explanation that the effect is driven by new information about the candidates, e.g., the effect is primarily driven by new donors rather than past donors, by candidates without Facebook accounts and tweeting more informatively. Overall, our findings imply that social media can intensify political competition by lowering costs of disseminating information for new entrants to their constituents and thus may reduce the barriers to enter politics.
