The Study Guide prepared by Janice Boucher Breuer of University of South Carolina , emphasizes the practical application of theory. Each Study Guide is a practicum designed to promote comprehension of economic principles and develop each student's ability to apply them to different problems. The Study Guide contains by chapter: an overview of the corresponding chapter in the textbook, a checklist to provide a quick review of material covered in the textbook and lectures, a list of key terms and their definitions, practice exams, and the detailed answer keys.
