Introduction
This chapter introduces the book and discusses its main objective—the microeconomic analysis of product innovation—and its potential readership—third-year undergraduate and postgraduate students, researchers, private and public sector policy professionals—both in economics and in management and business. The chapter argues that this book will fill an important gap in the literature. It also provides an overview of subsequent chapters, summarizes their content, and describes the way they interact. In particular, it indicates that the material provided encompasses the definition of product innovation, the sources of new products, the measurement and extent of product innovation, analytical material on the demand for new products, their supply, and the incentives to product innovation, empirical material on the determination of the extent of product innovation, the diffusion or spread of product innovations, the impact of product innovation on firm performance, price measurement, and welfare and policy issues relating to product innovation.
