英文摘要:
Foreign power interference in domestic elections is an existential threat to societies. Manifested through myriad methods from war to words, such interference is a timely example of strategic interaction between economic and political agents. We model this interaction between rational game players as a continuous-time differential game, constructing an analytical model of this competition with a variety of payoff structures. All-or-nothing attitudes by only one player regarding the outcome of the game lead to an arms race in which both countries spend increasing amounts on interference and counter-interference operations. We then confront our model with data pertaining to the Russian interference in the 2016 United States presidential election contest. We introduce and estimate a Bayesian structural time series model of election polls and social media posts by Russian Twitter troll accounts. Our analytical model, while purposefully abstract and simple, adequately captures many temporal characteristics of the election and social media activity. We close with a discussion of our model\'s shortcomings and suggestions for future research.

中文摘要:
外国势力干涉国内选举是对社会的生存威胁。从战争到言论,这种干涉通过无数种方式表现出来,是经济和政治代理人之间战略互动的及时例子。我们将理性博弈者之间的这种相互作用建模为一个连续时间差分博弈,构建了一个具有多种支付结构的竞争分析模型。只有一个玩家对比赛结果持“要么全有,要么全无”的态度,这导致了一场军备竞赛,在这场竞赛中,两国在干涉和反干涉行动上的花费越来越多。然后,我们用有关俄罗斯干预2016年美国总统大选的数据来对抗我们的模型。我们介绍并估计了俄罗斯推特巨魔账户的选举投票和社交媒体帖子的贝叶斯结构时间序列模型。我们的分析模型虽然有目的地抽象和简单,但充分捕捉了选举和社交媒体活动的许多时间特征。最后,我们讨论了我们模型的不足之处,并对未来的研究提出了建议。
