The most successful first edition of a principles of economics text in Prentice Hall history. The authors build a framework for economic reasoning on the Five Principles of Economics then move the student from memorization to understanding by applying these simple, intuitive and memorable principles repeatedly throughout the text in an "active learning" environment (Economic Experiments, Economic Detective, Using the Tools). The goal is for students to not only think like economists, but to act like economists. The economic analysis is rigorous yet accessible to the average student. The organization is modern and balanced, with equal weight given to Classical (long-run comes first), Keynsian, and Monetarist philosophies, with an effort to show how they are linked. Designed for that majority of students who will not go on to other economics courses, the text also functions as a solid foundation for more advanced courses. PHLIP supported.
