Abstract

We show that firm and industry, rather than inventor and invention factors, explain more than half of the variation in inventor returns in administrative employer-inventor-patent-linked data from Germany. Between-firm variation in inventive rents is strongly associated with inventor mobility. Inventors are more likely to make a move just before a patent is filed than shortly thereafter and benefit from their move through a mobility-related marginal inventor return. Employers that pay inventor returns in excess of the expected return gain a favorable position in the market for inventive labor with subsequent increases in patent quality and quantity. Consistent with theoretical arguments, effect sizes also depend on employer-inventor technological complementarity, degree of competition, and invention quality.
