Private and Public Placement Services for Hard-to-Place Unemployed
基于德国两个劳动力市场机构的随机实验，发现公共就业服务比私营服务更能减少失业天数，但效果短暂且部分源于劳动力退出。
The authors analyze a randomized field experiment in two German labor market agencies that provide public and private provision of intensive job placement services. The findings, based on analysis of administrative agency data over 18 months in 2009–2010, show that assignment to public employment services reduced accumulated days in unemployment by one to two months, compared to an assignment to a private provider. The effects, however, were short-lived. Moreover, two-thirds of the effect is attributable to labor force withdrawals. Finally, several important differences in the modes of service provision are only partially attributable to inherent aspects of in-house production and contracting out.
