Paid Family Leave, Inventor Mobility, and Firm Innovation

Abstract

We exploit the adoption of US state-level Paid Family Leave (PFL) laws to test whether family-friendly policies affect firm innovation. We find that PFL policies increase the innovation outputs of firms whose employees are more exposed to these laws. The stronger attraction and the higher retention of female inventors contribute to the output gains. Tests at the state level suggest that younger inventors move into states after PFL adoption, and the move-in inventors are generally more productive than the move-out inventors at the personal level. Further tests at inventor level show that females are less likely to drop out from the inventor career after PFL adoption. Overall, the behavior change in inventor career choices is the main channel through which PFLs affect firm innovation.
