Brad DeLong's Macroeconomics offers a new approach to the subject. Drawing upon his vast experience teaching,researching,and advising the U.S. government on Economy policy has enabled him to write an intermediate macroeconomics book that will set the standard for books 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,incorporates a strong international perspective,and offers a broad historical perspective.
