Every page of this book affirms why Paul Krugman, holder of the Nobel Prize in Economics, is one of the most popular authors of economics books. This book, co-authored with Robin Wells, is already in its second edition.

The new edition is updated and at the same time informative, grounded in the solid foundation of fundamental economic principles, while also focusing on the realities of today's world and the needs of students. It bears the hallmark of the methodological approach of Krugman and Wells, which is based on the analysis of real situations, incorporating into new theoretical approaches a new thematic and content.

It explores classical and modern economic theories, presenting them in an easy and understandable way. Through the use of examples, the reader can discern how economic numbers manifest and how they connect with the models.

A Best Seller in both the English edition and in many languages into which it has been translated, it has rightly been characterized as 'an excellent text, beautifully written, where the examples clearly explain important economic principles.'
