The #1 best-selling intermediate macroeconomics book, Mankiw's masterful text covers the field as accessibly and concisely as possible, in a way that emphasizes the relevance of both macroeconomics's classical roots and its current practice. The new edition has been updated to deal with our ever-changing world, including the economic slowdown of 2001--associated at first with the end of the stock market boom and then with the terrorist attack of September 11--which has once again put business cycle theory at center stage.
