Economics in Business is a concise, business focused book which illustrates how the ideas and perspectives of economics can help us make sense of the world in which we live. This book takes a business first approach and then applies the economic theory to the business world. Business models such as Porter's five-forces are used to explain the relevance of the theory to business life and the real problems faced by firms and managers. This highly accessible book takes a reader-centred approach, communicating complex ideas in a straightforward and easy to understand manner. The book is suitable for undergraduate students studying a one-semester business economics course as part of a business degree. The book will also be appropriate for DMS students and MBA modules in economics.
