Labor Mobility Of Scientists, Technological Diffusion, and the Firms Patenting Decision
The authors develop and test a model of the patenting and research and development (R&D) decisions of an innovating firm whose scientist-employees sometime quit to join or start a rival. They show theoretically that the risk of a scientists departure reduces the firm AAAs R&D expenditures and raises its propensity to patent an innovation.
