This is a concise introduction to macroeconomics, specifically designed to provide students (MBA and undergraduate business studies) and practitioners of business with an understanding of the workings of the national and international economic systems. It examines key aspects of the economic environment which affect the business climate, such as inflation, business cycles, international trade and exchange rates. The approach adopted is hands on using a mixture of text examples and boxed illustrations, and topics are developed to highlight their relevance for firms. This book is a companion volume to Business and Microeconomics, which focuses on the workings of the market system.
