Are Educational Vouchers Only Redistributive?
研究哥伦比亚职业教育学校中通过抽签分配的教育券项目，发现中签者虽然同伴特征较差，但教育结果更好，表明教育券不仅通过再分配同伴起作用，还可能通过其他渠道提升教育产出。
It is unclear if vouchers increase educational productivity or are purely redistributive, benefiting recipients by giving them access to more desirable peers at others' expense. To examine this, we study an educational voucher programme in Colombia which allocated vouchers by lottery. Among voucher applicants to vocational schools, lottery winners were less likely to attend academic secondary schools and thus had peers with less desirable observable characteristics. Despite this, lottery winners had better educational outcomes. In this population, vouchers improved educational outcomes through channels beyond redistribution of desirable peers. We discuss potential channels which may explain the observed effects. Copyright © The Author(s). Journal compilation © Royal Economic Society 2010.
