The purpose of this book is to show how economic analysis can be used in formulating business policies. It is therefore a departure from the main stream of economic writings on the theory of the firm, much of which is too simple in its assumptions and too complicated in its logical development to be managerially useful. The big gap between the problems of logic that intrigue economic theorists and the problems of policy that plague practical management needs to be bridged in order to give executives access to the practical contributions that economic thinking can make to top-management policies.
