Macroeconomics is the leading scientific textbook by Paul Krugman (Nobel Prize in Economics 2008) and Robin Wells. A best seller in both the English edition and in many translated languages, it has rightly been described as "an excellent text, beautifully written, where examples clearly explain important economic principles."

Economics is an extremely powerful tool. It offers a logical view of the world, which in turn provides true guidelines for its improvement. The proper use of economic models is essential - understanding both their assumptions, their limitations, and their positive applications.

After all, we do not live in a world where "one model of Economics fits everywhere." An approach to these ambiguous concepts for solving real-world problems makes the reader more astute and an effective participant in our shared economic, social, and political life.

Krugman notably states that while most people are skilled in solving practical problems, they are not trained to think using mental and theoretical frameworks. For this reason, an exploration of classical and contemporary economic theories is attempted, presenting them in an easy and understandable manner.

Additionally, intuition is encouraged in each chapter through real-life examples. The elements of the real world illustrate concepts. Thus, the reader can discern how economic figures appear and how they relate to the models.

Supply and demand, income, expenditures, savings, investments, the financial and banking system, fiscal and monetary policy—all these are subjects of analysis in many macroeconomics books; however, it is this particular approach that makes this edition unique.
