How do peacebuilding institutions affect political behavior? This article studies the historic victory of the Colombian left in the 2022 presidential elections in light of the implementation of local peacebuilding programs through the 2016 Peace Accords. Using a quasi-experimental design, we show that the Development Plans with a Territorial Focus (PDET), a central component of the 2016 Peace Accords between the government and the FARC, increased the vote share for the leftist coalition, Pacto Histórico, in the 2022 elections by increasing voter turnout in PDET regions. In a departure from existing literature, we find that the explanatory effect of violence on vote share is significantly reduced when we include an indicator for PDET implementation and additional covariates. While there is a substantial body of work examining the effects of conflict violence and the presence of armed actors on elections, there has been relatively little focus on how the peacebuilding has affected vote choice and political behavior. We see our project as a bridge to fill this gap in the literature.

建设和平机构如何影响政治行为？本文研究了哥伦比亚左翼在 2022 年总统选举中的历史性胜利，因为通过 2016 年和平协议实施了当地建设和平计划。使用准实验设计，我们表明，以领土为重点的发展计划 （PDET） 是政府与 FARC 之间 2016 年和平协议的核心组成部分，通过提高 PDET 地区的选民投票率，增加了左翼联盟 Pacto Histórico 在 2022 年选举中的选票份额。与现有文献不同的是，我们发现，当我们包括 PDET 实施的指标和其他协变量时，暴力对选票份额的解释效果显着降低。虽然有大量工作研究冲突暴力和武装行为者的存在对选举的影响，但对和平建设如何影响投票选择和政治行为的关注相对较少。我们将我们的项目视为填补文献中这一空白的桥梁。
