Technology spillover through labor mobility in the presence of competition among multinationals
摘要
Labor turnover from foreign multinational enterprises (MNEs) to local firms is widely regarded as a key mechanism for technology spillover in host countries. However, in practice, many trained workers move between MNEs rather than transitioning to local firms. We develop a model in which technology advanced MNEs train local employees and later compete with other firms to retain these skilled workers. Our findings reveal an inverted U-shaped relationship between the degree of technology spillover through labor mobility and competition among MNEs. Specifically, when the number of MNEs is relatively small, the entry of new MNEs enhances technology spillover. However, once the number of MNEs exceeds a threshold, additional entries lead to a decline in technology spillover, as MNEs seek to retain workers to mitigate intensifying competition.
