Macroeconomics 2e offers a new approach to the subject. Drawing upon vast experience teaching, researching, and advising the U.S. government on policy has enabled the authors to write an intermediate macroeconomics book that will set the standard for books in this area for years to come. For example, DeLong/Olney focuses on the interest rate rather than the AS/AD diagram and includes expanded coverage of the crucial topic of long-run growth. This lively text is modern, provides extensive insight into economic policy, incorporates a strong international perspective, and offers a broad historical perspective.
