Written in an accessible tone and restricting its analysis to the use of microeconomics, this book encompasses the definition of product innovation. It explores means of measurement and revealed patterns of the extent of product innovation; the economic analysis of the forces driving the demand for, the supply of, and incentives to generate new products; empirical evidence upon the determinants of the extent of product innovation; the diffusion of product innovations; product innovation and firm performance; price measurement under product innovation; product innovation and welfare; and public policy and product innovation.
