This book attempts to present economics in a more lighthearted way and in very simple language in order to capture readers' interest. Clearly written without mathematical complexities, this book is ideal for students of economics at any level, practising economists in both private and public sectors who wish to catch up on what is new in economic theory, and to lawyers and sociologists who might be interested in a chapter devoted to the economic approach to law and to several chapters on human behaviour, respectively.
