The idea of duality has proved to be a powerful device in modern work on the economics of consumer behaviour. The authors have used duality to provide an integrated and accessible treatment of this subject. The book focuses on applications of the theory to welfare economics and econometric analysis.
The book begins with four chapters that provide a self-contained presentation of the basic theory and its use in applied econometrics. These chapters also include elementary extensions of the theory to labor supply, durable goods, the consumption function, and rationing. The rest of book is divided into three parts.
