Reviews of this book: "Outstanding! Rarely does academic literature attempt to convey the most complex content with such practical relevance and spirit. The author knows how to make things understandable. Never has economics been so concise and vivid." "Altmann has a talent that few can claim: he can write textbooks that are enjoyable to read until the end." "With this textbook, the author has achieved a remarkable feat. He guides the reader through comparatively complex economic contexts without assuming any specialized knowledge. Although this means that the entire conceptual framework must be explained in the text, this book reads remarkably easily. The author skillfully makes current references and carefully handles essential formal derivations. All central ideas are conveyed clearly and understandably.".
