This textbook provides a comprehensive overview of macroeconomic relationships and explains the most important macroeconomic variables in an easy-to-understand manner. The reader is introduced to important macroeconomic variables such as inflation and aggregate demand in chapters that build on one another. They learn, among other things, how economic crises arise or the role and functioning of money, capital and goods markets.  The aim is to provide the reader with economic knowledge that can be applied in business practice. The economics material has been deliberately selected so that business studies content is usefully supplemented. However, detailed explanations and both application-oriented and practice-related examples and exercises make it easy for non-economists to understand the complex economic topics. Well-founded knowledge presented in an immediately comprehensible way!
