Abstract

This article explores the effects of charter schools on teachers’ working conditions in Bogota (Colombia). By employing a semi-experimental approach involving Propensity Score Matching (PSM) and Difference-in-Differences (DID), we find that in the close vicinity (postcode area) of where they are established, charter schools more than double teachers’ workload for a comparatively small increase in salaries. In light of a neo-institutional approach, we argue that those advocating for the diversification of school types in Colombia have decoupled the presumed benefits of charter schools’ competition from their actual negative effects for teachers. Moreover, we also point out that despite charter schools in Colombia (Bogota) having a not-for-profit status, existing labour flexibilisation policies have exerted isomorphic pressures on them, forcing them to adopt short-term contracts and thus leading to ravaging competition practices among teachers. Overall, we contend that the introduction of charter schools in Colombia (Bogota) has led to a general precarisation of teachers’ working conditions.

摘要

本文探讨了特许学校对波哥大（哥伦比亚）教师工作条件的影响。通过采用涉及倾向得分匹配 (PSM) 和差异中的差异 (DID) 的半实验方法，我们发现，在它们建立的附近（邮政编码区域），特许学校的教师工作量增加了一倍以上工资涨幅相对较小。鉴于新制度方法，我们认为那些在哥伦比亚倡导学校类型多样化的人已经将特许学校竞争的假定利益与其对教师的实际负面影响脱钩。此外，我们还指出，尽管哥伦比亚（波哥大）的特许学校具有非营利地位，但现有的劳动力弹性政策对它们施加了同构的压力，迫使他们采用短期合同，从而导致教师之间的激烈竞争。总的来说，我们认为哥伦比亚（波哥大）特许学校的引入导致了教师工作条件的普遍不稳定。
