“Good” Firms, Worker Flows, and Local Productivity
利用意大利威尼托地区的社会保障和资产负债表数据，研究发现从高生产率企业招聘工人能显著提升其他企业的生产率，工人流动解释了地方新增高生产率企业带来的约10%的生产率增长。
This paper is the first to present direct evidence showing how localized knowledge spillovers arise from workers changing jobs within the same local labor market. Using a unique data set combining Social Security earnings records and balance sheet information for the Veneto region of Italy, I first identify a set of highly productive firms, then show that hiring workers with experience at these firms significantly increases the productivity of other firms. My findings imply that worker flows explain around 10% of the productivity gains experienced by incumbent firms when new highly productive firms are added to a local labor market.
