Field Before After
Paper Abstract To study the effects of non-partisan information and get-out-the-vote (GOTV) campaigns on the partisan composition of the voting population in competitive authoritarian elections, we conducted a large-scale field experiment prior to the 2018 Bangladeshi general election. Our two treatments highlight that high turnout increases the winning party’s legitimacy and that election outcomes matter for policy outcomes. Both treatments increase turnout (measured by ink marks) in government strongholds but decrease turnout in opposition strongholds. We explain the withdrawal of treated opposition supporters and conclude that non-partisan information and GOTV campaigns can further tilt the uneven playing field in competitive authoritarian elections
