Economics is global and the eighth edition of "principles of macroeconomics, international edition" maintains the hallmarks of the melvin/boyes series - accessible writing, strong pedagogy, and integration of global economic issues - while faithfully presenting the latest thinking of economists on important macroeconomic phenomena. The authors have carefully integrated their popular pedagogy, cutting-edge teaching and learning technology, and a full range of supplements to create a complete program that clearly illustrates the connections between key macroeconomic principles and real-world business practices. The text has also been thoroughly updated with recent data and extensive coverage of important current issues, such as the economic effects of the war in iraq, the 2008 financial crisis, and china's emergence as an economic power.
