We look at how the arrival of an invention affects wage returns and probability of moving out of employment for white- and blue-collar coworkers of the inventor. First results suggest that older workers are hurt by the arrival of an invention. This negative effect disappears when we control for education and, in particular, for time that since obtaining the last formal degree, i.e., distance to human capital frontier . If anything, this effect is slightly higher for non-STEM than STEM-educated co-workers. This result suggests that retraining programs could be helpful in making the process of creative destruction and economic growth more inclusive.

We analyze how demand conditions faced by a firm in its export markets affect its innovation decisions. We exploit exogenous firm-level export demand shocks and find that firms respond by patenting more; furthermore this response is driven by the subset of initially more productive firms. The patent response arises 2 to 5 years after the shock, highlighting the time required to innovate. In contrast, the demand shock raises contemporaneous sales and employment for all firms regardless of their productivity. This skewed innovation response to common demand shocks arises naturally from a model of endogenous innovation and competition with firm heterogeneity.

How does firm entry affect innovation incentives in incumbent firms? Microdata suggest that there is heterogeneity across industries. Specifically, incumbent productivity growth and patenting is positively correlated with lagged greenfield foreign firm entry in technologically advanced industries, but not in laggard industries. In this paper we provide evidence that these correlations arise from a causal effect predicted by Schumpeterian growth theory—the threat of technologically advanced entry spurs innovation incentives in sectors close to the technology frontier, where successful innovation allows incumbents to survive the threat, but discourages innovation in laggard sectors, where the threat reduces incumbents' expected rents from innovating. We find that the empirical patterns hold using rich micro panel data for the United Kingdom. We control for the endogeneity of entry by exploiting major European and U.K. policy reforms, and allow for endogeneity of additional factors. We complement the analysis for foreign entry with evidence for domestic entry and entry through imports.
