Incorporating recent advances in modern macroeconomics, this fifth edition offers increased coverage of long-run analysis and a new treatment of US policy rules and price adjustment. The authors provide a thorough account of the Solow Growth Model, develop the insights of endogenous-growth theory, explain the role of fiscal and monetary policy in the long run, and present a structural look at unemployment. Having examined the US monetary system and the Fed's policy rule, and on fluctuations in inflation and output, the book goes on to discuss how the policy rule is integrated into the general model of the economy. Also available are a corresponding study guide, instructor's manual, and test-item file.
