External knowledge sourcing: science, market and the value of patented inventions
This paper analyzes the choice between alternative sources of knowledge in patented inventions. Inventors can use scientific and|or market-oriented sources of knowledge. We formally test whether these two types of knowledge acquisition are complementary or substitutable in the value of patented inventions. The results suggest that simultaneous exploitation of different knowledge inputs is 'subadditive' since inventors would have to manage assimilation and integration of disparate items of external knowledge stemming from distant technological contexts.
