Williamson's third Canadian edition ofMacroeconomicsbuilds macroeconomic models from microeconomic principles, an approach consistent with the way that macroeconomic research is conducted today. This modern approach and emphasis on microeconomic foundations will better prepare students for advanced study in economics and is unlike any other text on the market.

Iris Au and Jack Parkinson of the University of Toronto, Scarborough have "Canadianized" the Macroeconomics section of Krugman/Wells, Economics, Third Edition, maintaining the structure and spirit of the U.S. version but adapting it to reflect Canadian macroeconomic policies and to appeal more directly to Canadian instructors and students. In almost every instance, U.S. data sets, cases, research, and policy discussions have been supplanted by Canadian material.
