A Text Book of Business Economics

PREFACE
The economic techniques have gained a wide application in
the process of modem management decision, possible, because
recent business problems have become so complex that manager's
personal experience is no longer adequate to give an appropriate
solution. The purpose of this book is to provide, in one volume, the
different economic theories which are deemed to constitute the
subject matter of managerial economics. This book is written
especially for B.Com., B.B.A., M.Com., M.B.A., and c.A. students of
our country.
This book is intended to explain in non-technical language, the
economic concepts, tools of analysis, their relevance in management
decision-making and also the influence of economic environment
on management decisions. To facilitate an easy understanding of
the subject, the timely help of illustrations, examr::es, diagrams,
tables and charts has been taken, Important terms relevant to the
business economics are given in a separate chapter. To my publisher,
I am grateful for publishing the book with due care and skill in a
very short time. I shall be thankful to the readers for pointing out
discrepancies and errors in the text, which I hope to rectify in the
next edition of the book. Suggestions for further improvement of
this book will be highly appreciated.
