Is Information Power? Using Mobile Phones and Free Newspapers during an Election in Mozambique
在莫桑比克选举中随机试验三种选民教育方式（短信宣传、举报热线、免费报纸），发现三者均提高投票率，但只有免费报纸增强了问责参与并减少了选举问题。
African elections often reveal low levels of political accountability. We assess different forms of voter education during an election in Mozambique. Three interventions providing information to voters and calling for their participation were randomized: an information campaign using SMS, an SMS hotline for electoral misconduct, and the distribution of a free newspaper. To measure impact, we look at official electoral results, reports by electoral observers, and behavioral and survey data. We find positive effects of all treatments on voter turnout. However, only the distribution of the free newspaper led to more accountability-based participation and to a decrease in electoral problems.
