Why some firms never invest in formal R&D

In this paper we study the frequency of formal R&D investments. We link real options theory to the knowledge‐based view to explain how a firm's knowledge resources influence its frequency of investing in R&D to establish technological options. Specifically, we propose that a firm that lacks internal knowledge resources is more likely to never invest in R&D, a firm that has both internal and external knowledge resources is more likely to sometimes invest in R&D, while a firm that has internal knowledge resources but lacks external knowledge resources is more likely to always invest in R&D.
