The aim of this book is to make the subject of economics more accessible and relevant to those studying it as part of a business-related degree or professional examinations. It covers all the major principles of economics, but its focus throughout is firmly on applying these principles to the business environment. This book is a determined attempt to furnish up-to-date knowledge of business economics in a simple and lucid manner. It will be of great use not only for commerce and arts students but also for CA and CS students.
