Description This book offers a new approach to the subject of macroeconomics. Drawing upon his vast experience of teaching, researching and advising the U.S. government on Economy policy has enabled the author to write an intermediate macroeconomics book that will set the standard in this area for years to come. For example, DeLong focuses on the interest rate rather than the AS/AD diagram and he includes expanded coverage of the crucial topic of long-run growth. His lively text is modern, provides extensive insight into economic policy, and offers a broad historical and international perspective.
