“…Existing work has tested rational choice models of voter turnout structurally (e.g., Coate andConlin, 2004 andCoate et al, 2008) and in the lab (e.g., Levine and Palfrey, 2007, Duffy and Tavits, 2008, and Agranov et al, 2018, finding mixed results. It has also identified other drivers of voter turnout: expressive motives (Pons and Tricaud, 2018), personality traits (Ortoleva and Snowberg, 2015), habits (Fujiwara et al, 2016), social considerations (Gerber et al, 2016, Funk, 2010, and DellaVigna et al, 2016, political movements (Madestam et al, 2013), media content (Strömberg, 2004, Gentzkow, 2006, DellaVigna and Kaplan, 2007, Enikolopov et al, 2011, Gentzkow et al, 2011, and Spenkuch and Toniatti, 2018, the existence of exit poll results (Morton et al, 2015), and compulsory voting laws (León, 2017 andHoffman et al, 2017). 6 Our evidence of a causal effect of anticipated election closeness complements this empirical literature and provides support for theoretical models in which voter turnout increases with beliefs about closeness.…”
