The legacy and promise of Vannevar Bush: rethinking the model of innovation and the role of public policy

Abstract

ABSTRACTThe linear model of innovation argues that innovation takes place in a unidirectional sequence, with basic research directly diffusing in marketable product or process innovations. This perspective has served society well in past decades. However, recent productivity slowdowns in developed economies and the failure of innovation policies to continue to deliver desired results have called this perspective into question. Scholars explain these slowdowns by the oversimplification of the linear model which fails to consider the complexities associated with innovation processes. Although it is generally believed that Vannevar Bush’s report Science – The Endless Frontier – was based on his belief in a linear model of innovation and the notion that basic research is the ultimate source of all innovation, an examination of Bush’s writings and his life reveals that he believed in a more sophisticated model in which basic and applied research cross-fertilize each other and in which government’s job is not so much to stimulate basic research as it is to facilitate interactions between basic and applied research for the benefit of both and the prosperity of society. This paper explicates Bush’s model of the research and innovation process, explores the implications of that model, and derives policy recommendations.
