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.
