“The convergent geoeconomic dynamics, identified as globalization, is an integrative phenomenon of the economy in space, built through different cyclical waves of long-term accumulation in the capitalist system since the 15th century, despite divergent geopolitical and geocultural vectors. in the international system. It is a book whose thought-provoking title aims to arouse questions and a broad economic reflection to outline possible explanations on current themes of growth, development and crisis in the capitalist accumulation system in the light of the synchronous transformations underway in the world. Written collaboratively by a group of Brazilian, Mexican and Portuguese researchers, this book reflects the developmentalist sense of globalization as a phenomenon of expansion of human interactions, thus qualifying itself as a work that reflects and is a reflection of its own time. .”

The book “Economy” exposes the various current divisions from the point of view of the neoclassical current, and the book presented is based on an analysis of two qualities: microeconomics and macroeconomics. Microeconomics is the branch of economic science that studies price formation, the main variable that guides the allocation of resources in the context of capitalist economies. Discusses the functionality of markets to ensure the efficient organization and distribution of resources or factors of production that, by nature, are scarce. His particular study focus is formed by the characteristics of a myriad of specific markets, examining the behavior and interaction of the various economic agents. Macroeconomics is the branch of economic science that studies the behavior of the economy as a whole, having as targets, eg, output, employment, inflation and international trade. This scientific work also embraces the role of the State in its various functions, eg locating, distributing and stabilizing economic and social activity.

"The legal subsystem is in close relationship with the other social subsystems (economic, political and cultural) in a certain way, integrating a whole that is the social system. The legal subsystem triggers effects on other subsystems, either through the design of norms or through their application, and, in turn, is influenced by them. Law is an expected value given that its efficiency depends not only on what norms determine, but also on the likelihood of law enforcement in all domains of social relations. This book deals, above all, with the economic analysis of contracts and crime, areas of study and action of paramount importance in any society.”

As for the 2nd edition of the book that is now published, “Microeconomics Exercises Proposed and Resolved”, by authors António Duarte Santos and Sandra Ribeiro, with extensive experience in the scope of the subject that is the focus of this book, in addition to their knowledge in other areas of Economics, we want to emphasize its importance for everyone who begins their studies in the field of Economics.

The book contains a brief introduction entitled “The nature of economics”, which provides a brief overview of the various essential issues in the field of economics.

Each chapter begins with clear expositions of theory, principles, or background information. Following are the questions that can be multiple choice or descriptive, including their explanation by analytical expressions. The solved problems serve as an illustration of the application of the corresponding theory, allowing the deepening of the theory and, consequently, the effective learning.

In conclusion, the subject matters of this book, now in its 2nd enlarged edition, constitute an essential element for the study of economics, albeit in the part that is normally designated as Microeconomics.
