The Incentives to, and Constraints upon, Product Innovation
This chapter explores the factors that affect the firm’s decision to undertake product innovation. The discussion encompasses the driving forces that encourage product innovation, for example innovation by others or the ageing of an existing product line; however, the basic rationale is the search for profits. The chapter also addresses decisions about: the extent of innovation in general; horizontal and vertical product innovations separately; and the location of innovations in product space. The role of market structures in the product innovation decision, uncertainty in the innovating environment, and issues relating to emulation and copying are also addressed. Constraints to product innovation that survey data indicate are most important—innovation costs, risk and finance, and the availability of qualified labour—are also addressed.
