Research and write a two- to three-page paper, in APA Style, analyzing macroeconomic theories and the Great Depression. Consider the following to guide your research and writing. Explore the various macroeconomic theories and explain the differences between each one (classical, Keynesian, and monetarist). Explain why monetarists believe the Fed should have stimulated the economy by expanding the money supply during the Great Depression or other economic downturns. The Keynesians challenge the Friedman–Schwartz monetarists’ monetary policy cure for the Great Depression. Use the AD-AS model to explain the Keynesian view. (Hint: Your answer must include the investment-demand curve.)
