Reviewers tell us that Case/Fair is one of the all-time bestselling principles of economics texts because they trust it to be clear, thorough and complete. This well-respected author team is joined for the 9 th edition by a new co-author, Sharon Oster. Sharonrs"s research and teaching experience brings new coverage of modern topics and an applied approach to economic theory, as demonstrated in the newEconomics in Practicefeature. This text is for those looking for a trusted and authoritative principles of macroeconomics book that focuses on international economies as well as the Keynesian Cross. Case/Fair/Oster believe strongly, that a text should use the Keynesian Cross carefully and systematically, to build up to the AD/AS model. One of the great benefits of this approach, is that students of economics wonrs"t mistakenly apply what they learned about simple demand and supply to aggregate demand & supply. (A detailed summary of this approach can be found in the preface). 0138001928 / 9780138001926 Principles of Macroeonomics & MyEconLab Student Access Code & MEL Package Package consists of: 0136058965 / 9780136058960 Principles of Macroeconomics 0136124755 / 9780136124757 MyEconLab Student Access Code Card
