The dynamics of knowledge flows: human capital mobility, knowledge retention and change

This empirical paper investigates the relationships between the amount of human capital that flows into a firm and two activities underlying a firm’s knowledge production, variation or change and knowledge retention. We track the flow of human capital within and across organizational and geographic space for all multi‐unit banks operating in the world foreign exchange trade industry from 1973 to 1993. The findings indicate that an increased reliance on past experience reduces how much human capital a firm imports in the future. This effect is moderated by a self‐reinforcing cycle of human capital inflow. Inflows of human capital also decline when a firm has recently adopted novel changes in its operations. The paper uses evolutionary thinking to define a model for intrafirm knowledge production.
