This introductory text meets the needs of economics and business students who require a rigorous and jargon-free presentation of the subject. It covers the entire framework of economics in a single volume and presupposes no previous knowledge. It is suitable for GCE A-level and professional examinations, BTEC National and Higher National level courses, and first-year degree students. The third edition takes into account new approaches to economics, emphasizes real-world economic and political changes, and has been updated with more international data. Each chapter includes a summary, essay questions and a data-response section.
