The classic introduction to macroeconomics. The focus is on the representation and comparison of the goods, money, and labor markets, as well as the overall economic equilibrium among "classical" and "Keynesian" perspectives. Key topics include: - The classification and subject matter of macroeconomics - Methods of analyzing the economic process - The economic cycle - Results of the economic cycle - Global indicators of the labor market - The goods market - The money market - The labor market - Overall economic equilibrium - Classical approach and supply-oriented economic policy - Keynesian approach and demand-oriented economic policy.
