Multiplicative-innovation synergies: tests in technological acquisitions

Technological innovations enjoy synergies that vary in their speed and magnitude of impact, depending upon whether they are additive or multiplicative in nature. Additive-innovation synergies build incrementally on familiar technologies (as is reflected in the technologies built upon within their patents’ respective antecedents) and the duration of their effect is shorter-lived. Multiplicative-innovation synergies arise from combining greater proportions of diverse technologies and their effects have longer duration. The most-effective organizational-learning processes accompanying exposure to exotic technology streams via technological acquisition will occur if firms have properly invested in adaptive capacity to synthesize inventions using the unfamiliar knowledge. In the first tests of innovation synergies on firm performance, we find that technological novelty in patent content improves return on assets for firms that consistently invested in R&D. Using patent-content scores to characterize whether inventors have integrated greater proportions of exotic technological antecedents into their inventions (or not), we test the impact of innovation synergies on firms’ performance after technological acquisitions. Diversification posture (which could be an alternative explanation for performance differences) is negatively-correlated with innovation synergies in our results.
