This work offers a comprehensive and in-depth analysis of the main concepts, theories, and policies that shape the global economy. Structured in six parts, it explores from the fundamentals of macroeconomics to advanced topics such as secular stagnation, financial crises, and the challenges of contemporary economic policies. Written in clear and precise language, it is intended for students, researchers, and economic professionals seeking to understand the mechanisms behind economic growth, inflation, unemployment, fiscal and monetary policies, as well as the integration of economies in the international scenario.

Throughout the chapters, it addresses classical and modern theories, including the IS-LM model, the Phillips curve, monetarism, Keynesianism, and discussions on macroeconomic policies in open economies, based on the Mundell-Fleming model. The work also examines the political economy of macroeconomics, exploring how electoral cycles, interest groups, and populism influence economic decisions. The final chapters provide an analysis of the future perspectives for macroeconomics, considering the impact of technology, climate change, globalization, and demographic trends.

Combining academic rigor and practical applicability, this work stands out as an essential reference for those seeking to understand the current economic challenges and develop effective strategies to address them. The inclusion of case studies, historical examples, and analyses of recent economic policies offers readers a critical and contextualized view of macroeconomic issues.
