英文摘要：
  We develop an equilibrium theory of attention and politics. In a spatial model of electoral competition where candidates have varying policy preferences, we examine what kinds of political behaviors capture voters\' limited attention and how this concern affects the overall political outcomes. Following the seminal works of Downs (1957) and Sims (1998), we assume that voters are rationally inattentive and can process information about the policies at a cost proportional to entropy reduction. The main finding is an equilibrium phenomenon called attention- and media-driven extremism, namely as we increase the attention cost or garble the news technology, a truncated set of the equilibria captures voters\' attention through enlarging the policy differentials between the varying types of the candidates. We supplement our analysis with historical accounts, and discuss its relevance in the new era featured with greater media choices and distractions, as well as the rise of partisan media and fake news.

中文摘要：
我们发展了注意力与政治的平衡理论。在候选人具有不同政策偏好的选举竞争空间模型中，我们研究了什么样的政治行为吸引了选民有限的注意力，以及这种关注如何影响总体政治结果。继唐斯（1957）和西姆斯（1998）的开创性工作之后，我们假设选民在理性上是不注意的，并且可以以与熵减少成比例的成本处理有关政策的信息。主要发现是一种被称为关注和媒体驱动的极端主义的均衡现象，即当我们增加关注成本或篡改新闻技术时，一组截短的均衡通过扩大不同类型候选人之间的政策差异来吸引选民的注意。我们用历史记录来补充我们的分析，并讨论它在新时代的相关性，新时代的特点是媒体选择更多，注意力分散，以及党派媒体和假新闻的兴起。
