Macroeconomics (12th Edition, 2025) by N. Gregory Mankiw provides a comprehensive overview of the principles and models that drive national and global economies. The book covers key macroeconomic topics such as GDP, inflation, unemployment, fiscal and monetary policy, long-term economic growth, and international trade. Mankiw emphasizes both classical and Keynesian perspectives, explaining how economies behave in the short run versus the long run. His clear writing, real-world examples, and updated data help students understand the dynamic nature of macroeconomics and apply theoretical concepts to current economic events.

Mankiw also integrates behavioral economics insights and modern economic tools to better reflect how policy decisions affect aggregate demand and supply. The book maintains a balanced approach by discussing the strengths and limitations of various economic models, making it an essential resource for anyone seeking to understand how economic policy and market forces shape the world¹.
