Patents, Firm Rents, and Worker Compensation: Causal Evidence from Quasi-Random Patent Allocation
ZEW Discussion Paper No. 26-022 // 2026This paper provides new causal evidence on how patent allowances affect firms and their employees based on quasi-random assignment of patent applications to examiners. Exploiting employer–employee records with newly linked German firm data and web-scraped patent documents, it shows that patent-induced shocks reduce firm exit, improve productivity, and increase wages, with rent-sharing elasticities between 0.10 and 0.21. Wage gains are broadly observed across occupational tasks, with substantial heterogeneity: managers benefit dispro portionately in publicly traded firms, whereas broader wage increases accrue to workers in non-traded firms. The findings highlight the role of institutional features and firm organiza tion in shaping how rents are shared.
