衰退与复苏期间对小企业的支持

研究问题
政府贷款担保与信用质量认证如何影响小企业融资、投资和就业,其作用在经济危机与复苏阶段有何差异?
方法与思路
作者利用政府信用认证项目准入差异,以多维断点回归估计实体效应,并比较危机与复苏期间的项目影响。
材料陈述的贡献
摘要称,合资格企业借款更多、利率更低,危机期投资就业增加;复苏期效应较弱且更集中于认证,每岗位成本较低。
阅读关注点
应核对多维资格边界的可比性、担保与认证效应如何区分,以及跨阶段效应和每岗位成本的估计口径。
阅读边界
摘要未说明资格阈值、断点识别条件及成本核算细节;行业生产率异质性下降仅被解释为与信贷配置改善相一致。

原文摘要

We use variation in the access to a government credit certification program to estimate the financial and real effects of supporting small firms. This program was first implemented during the global financial crisis, but has remained active ever since, allowing us to analyze its effects both during recessions and recoveries. Eligible firms have access to government loan guarantees and a credit quality certification. We estimate real effects using a multidimensional regression discontinuity design. We find that eligible firms borrow more and at lower rates than non-eligible firms, allowing them to increase investment and employment during crises. Industry-level analysis shows reduced productivity heterogeneity in more exposed industries, which is consistent with improved credit allocation. However, when the economy is recovering the effects of the program are less pronounced and centered on the certification component. The cost-per-job in the recovery period is half of the one estimated for the crisis period (5784€ and 11,788€, respectively).
