The Effects of Knowledge Spillovers through Labor Mobility

We estimate the effects of knowledge spillovers on firms’ performance and workers’ wages. We use an innovation support program as an exogenous shock to the knowledge of non-participant firms and an employer-employee dataset to track the mobility of workers—and knowledge diffusion—between firms. We find that non-participants that acquired new knowledge by hiring skilled workers exposed to the program increased employment, the average wage they pay, exports, and productivity. Finally, we find that—depending on the level of competition—a wage premium was paid either by participant or non-participant firms to retain or acquire workers.
