This paper examines the long-run impacts of income shocks by exploiting variation in coffee cultivation patterns within Colombia and world coffee prices during cohorts’ school-going years. The results indicate that cohorts that faced higher returns to coffee-related work in childhood completed fewer years of schooling and have lower adult earnings scores. Several pieces of evidence suggest that these results reflect changes in educational decisions induced by temporary changes in the opportunity cost of schooling. These findings are consistent with the possibility that students may ignore or heavily discount the future consequences of dropout decisions when faced with immediate income gains.

当前的偏见和对教育的投资不足？儿童时期接触动臂的长期影响

本文通过研究哥伦比亚人在上学期间的咖啡种植方式变化和世界咖啡价格，考察了收入冲击的长期影响。结果表明，在儿童时期面临较高与咖啡相关工作回报的队列中，受教育时间较短的成年人，其成年人的收入得分较低。几项证据表明，这些结果反映了教育机会成本暂时变化引起的教育决策变化。这些发现与学生面对直接的收入增长而忽略或放弃辍学决定的未来后果的可能性是一致的。
