Retaining skilled employees: A human capital model with innovation and entrepreneurship

In his seminal paper, Becker argues that firms never invest in general human capital in a frictionless labor market. Nevertheless, empirical evidence shows the opposite. This paper sheds light on this puzzle by developing a principal–agent model with human capital investments. The novel feature of the model is that specific human capital increases the agent's probability to innovate. Innovation brings the opportunity of entrepreneurship, which means losing a skilled agent for the principal. The results show that higher entrepreneurial income increases the risk of employee departure and the principal may use general human capital investment for retention.
