Microeconomic theory

Authors, P.R. G. Layard, of The London School of Economics and A.A. Walters, the Johns Hopkins University Baltimore, Maryland " have concentrated on those parts of economic theory which are not regularly used in trying to solve rea-world problems. Most of this book is about positive economics - one purpose is to discover facts relevant to public policy. The exercises in the book are an "intrinsic part of the text".
