Economics 4th edition is a concise introduction to the core principles of economics, aimed at students taking their first, and probably only, one semester course in Economics. These students may be taking a business related degree, or may be from other degree schemes in the university taking a service course in Introductory Economics. There is a balanced split between the micro and macro economics section and the use of case studies and numerous examples makes this a lively little book for the reader.The real difference that this book offers the student is the amount and variety of questioning material that will really test their understanding.
