Worker Turnover and Job Reallocation: Evidence from Matched Employer-Employee Data
利用埃塞俄比亚的雇主-雇员数据，发现工人流动率高达38%，其中近一半由企业岗位流动驱动，另一半由过度流动或人员更替造成；人员更替与后续就业增长负相关，尤其在依赖长期雇佣关系的企业中更明显。
This paper uses employer-employee data to jointly examine worker turnover and job flows in Ethiopia. We find substantial worker turnover (38%) at the aggregate level. Nearly half of this turnover is driven by establishment-level job flows, while the other half is accounted for by excess turnover or churning. A substantial part of hiring (separation) occurs among downsizing (growing) establishments, underscoring that worker flows are much higher than job reallocation across establishments. Churning of workers appears to be negatively associated with subsequent employment growth, and this relationship is stronger among employers that rely more on long-term relationships with workers.
