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 moves 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 student to not only think like economists, but to act like economists. The economics analysis is rigorous yet accessible to the average student. The microeconomics organization is modern and balanced, with equal weight given to showing how they are linked. WebCT, Blackboard, myPHLIP supported.
