There are lots of people who pretend to understand Economics, but there are very few who really do understand Economics. If you dive into Economics and race towards your exams without taking the time to properly understand the key concepts at the heart of the subject, it will hardly be a surprise if you end up amongst the fakers rather than amongst the true experts.This book is intended for students who are considering studying Economics, for students who are soon to begin a course in Economics and for those who are already studying Economics but who would like to firm up their understanding of the key concepts at the heart of this fascinating and incredibly important discipline.
