Knowledge Transfers from Multinational to Domestic Firms: Evidence from Worker Mobility
利用巴西企业-工人匹配数据，研究发现跨国公司工人跳槽到国内企业后，会带动国内企业留任工人工资上涨，且技能越高的流动工人和留任工人，知识转移效果越好。
Labor turnover is a commonly cited mechanism for the transmission of technology from multinational to domestic firms. Using a matched establishment-worker database from Brazil, I present evidence consistent with positive multinational wage spillovers through worker mobility. When workers leave multinationals and are rehired at domestic establishments, continuing-workers' wages increase. To my knowledge, this avenue for wage spillovers has not previously been explored. The paper also investigates where spillovers occur and how they are absorbed to demonstrate heterogeneous impacts. Higher-skilled former multinational workers are better able to transfer information, and higher-skilled incumbent domestic workers are better able to absorb information. © 2013 The President and Fellows of Harvard College and the Massachusetts Institute of Technology.
