Economics: Principles and Policy with Xtra! Student CD-ROM

Economics: Principles and Policy remains a proven leader in the world of economics. Since introducing the aggregate supply/aggregate demand model as a fundamental tool for learning economics over two decades ago, William J. Baumol and Alan S. Blinder continue to equip students with the knowledge and tools they need to apply modern economics to their world--now and in the future. This is all the more true today, as the U.S. economy enters its first recession in more than a decade.
