Strategic R&D and the innovation of products: understanding the role of time preferences and product differentiation

Jason Walter and Jeffrey Peterson ()

Economics of Innovation and New Technology, 2017, vol. 26, issue 7, 575-595

Abstract: We evaluate the effects of innovation on competition using an optimal control approach that incorporates firms' time preferences. Using a model where firm(s) innovates by investing in research and development to create a more appealing product for heterogeneous consumers, we examine conditions that maximize social welfare. When firm(s) choose discount rate regardless of market structure, a monopoly will develop more innovative products. However, we show that duopolies may increase innovation if competition alters firms' outlook. Finally, we identify firm incentives to behave myopically, which in the context of collusion may impede industry-wide innovation.
