In this book, distinguished professors Mankiw and Taylor present and analyze the material that constitutes the usual content of introductory textbooks in Economic Theory, based on two elements: the given institutional framework of the free market and ten principles of economic behavior. The content of the book is the subject matter taught in Microeconomics and Macroeconomics courses, namely the theory of price determination for goods and productive factors, income determination, international trade, labor market, public sector, economic development, market forms, financial markets, etc. However, there are also interesting topics that are not covered in other textbooks, such as:
- Arrow's impossibility theorem
- Condorcet's paradox
- The problem of time inconsistency
- The concept of social justice, etc.

The book is enriched with:
- Supplementary material
- Numerical and diagrammatic examples
- Case studies of problems
- Excerpts from the international press
- Informational texts on topics or individuals (Smith, Ricardo)

It is an excellent aid for the study of Economic Sciences. Its impressive characteristic is the clarity and completeness of the analysis.
