Abstract We analyze the effect of worker inflows on establishments’ productivity, using German data. Previous studies for other countries have found positive effects of hiring workers from superior (more productive or higher paying) firms. Ranking establishments by their median wage, we find that inflows from inferior establishments seem to increase hiring establishments’ productivity. Further empirical analyses suggest our findings are due to a positive selection of such inflows from their sending establishments. These workers might have to find a better job match in order to advance their careers, an interpretation supported by the finding that the effect is driven by workers with short tenure at their previous employer. Our findings reflect the increasingly assortative pattern of worker mobility in Germany found in a related strand of literature.

异构企业之间工人流动的生产率影响

摘要我们使用德国数据分析了劳动力流入对企业生产率的影响。以前对其他国家的研究发现，从高级（生产性更高或薪资更高）的公司雇用工人具有积极作用。按营业场所的中位工资排名，我们发现劣等营业场所的流入似乎可以提高雇用营业场所的生产率。进一步的经验分析表明，我们的发现归因于从其发送机构对此类流入的积极选择。这些工人可能必须找到更好的工作岗位才能​​发展自己的职业，这一解释得到了这一发现的支持，即这种影响是由前任任期短的工人所驱动的。
