Preface The 12th edition of Microeconomic Theory: Basic Principles and Extensions continues a suc- cessful collaboration between the authors starting with the 10th edition. This edition rep- resents our efforts to continue refining and modernizing our treatment of microeconomic theory. Despite the significant changes appearing in virtually every chapter, the text retains all of the elements that have made it successful for so many editions. The basic approach is to focus on building intuition about economic models while providing students with the mathematical tools needed to go further in their studies. The text also seeks to facilitate that linkage by pro...
