Should Firms Avoid Relying on Key Employees? Evidence From Inventors

European Financial Management, EarlyView.
ABSTRACT Analysing inventor careers in U.S. public firms, we find that higher inventor‐base concentration enhances corporate innovation productivity in subsequent years, a relationship that remains consistent across various model specifications. Concentration improves the retention of individual inventors and teams, supporting the employee retention ...
