中文摘要
大量文献记录了内战冲突对不同国家和历史时期受影响儿童教育结果的负面效应。然而,相反的效应却并不显而易见。由于冲突可能破坏教育基础设施,而暴力减少会吸引经济活动、从而提高就学的机会成本,受冲突影响的社会在暴力结束后可能需要很长时间才能弥补人力资本的损失。本文研究哥伦比亚近期终结与FARC叛乱冲突的努力对短期辍学率的影响。我们采用双重差分识别策略,发现在政府与FARC和平谈判期间FARC宣布的永久停火,使停火前受FARC暴力影响最严重的地区相对于其他地区,其辍学率出现了较大的差异性下降。我们表明,这些结果主要并非由冲突期间儿童被招募所驱动。相反,我们的证据表明,辍学率下降的大部分是由经历FARC暴力地区总体受害程度下降所激励的。此外,停火对辍学率的影响被原受FARC影响地区同期古柯种植的增加所削弱。
Abstract
A large body of literature has documented negative effects of civil conflict on the educational outcomes of affected children across different countries and historical periods. The opposite is however not obvious. Because conflict can damage educational infrastructure, and violence reductions attract economic activity and thus increase the opportunity cost of schooling, it may take a long time for conflict-affected societies to offset the loss in human capital after violence is over. In this paper we study the effect of Colombia’s recent efforts to end the conflict with the FARC insurgency on short-term school dropout rates. Using a difference-in-differences identification strategy, we find that the permanent ceasefire declared by FARC during peace negotiations with the government induced a large differential reduction on school dropout rates in the areas most affected by FARC violence prior to the ceasefire, relative to other areas. We show that these results are mainly not driven by the recruitment of children during conflict. Rather, our evidence suggests that most the reduction in school dropout is incentivized by a decrease in the overall victimization in areas that experienced FARC violence. Moreover, the effect of the ceasefire on dropout rates is attenuated by the contemporaneous increase in coca growing in for- mer FARC-affected regions.
