Principles of Economics covers scope and sequence requirements for a two-semester introductory economics course. The authors take a balanced approach to micro- and macroeconomics, to both Keynesian and classical views, and to the theory and application of economics concepts. The text also includes many current examples, which are handled in a politically equitable way.
