Steering Labor Mobility Through Innovation

This paper argues that firms proactively use innovation decisions to influence the mobility and human capital accumulation of their workers. We develop a dynamic model in which workers conduct R&D projects, accumulating both general and firm-specific human capital. Firms choose the scope of innovation, influencing the type of human capital workers accumulate during the process. Pursuing more general innovation leads to increased knowledge redeployability for the firm at the cost of more difficult employee retention. We estimate the model using granular innovation production and mobility data of three million inventors. Our model closely matches the observed mobility and innovation specificity over inventors' life cycles. Empirical estimates of the model parameters imply that 24% of observed innovation specificity among U.S. firms is driven by their labor market considerations, which enhances the firm value but lowers the inventors' surplus.
