Learning Objectives • Understand the historical volatility in velocity and money demand and the implications of that volatility for Keynesianism and monetarism • Explain the fiscal and monetary policy lags and resulting difficulties in enacting these policies • Analyze the empirical evidence relating monetary and fiscal policies to GDP, investment, consumption, and interest rates Copyright © 2009 Pearson Addison-Wesley. All rights reserved. 28-2 Introduction • Previous chapters dealt with theoretical concepts of monetary theory on economic activity • This chapter explores empirical evidence – How are interest rates affected – What categories of spending are most influenced – Does monetary policy alter real economic outcomes—output and unemployment—as compared to changes in prices Copyright © 2009 Pearson Addison-Wesley. All rights reserved. 28-3 1 Living with Velocity • Much of Monetarist-Keynesian debate hinges on the behavior of velocity – Monetarists—relatively stable and changes are highly predictable – Keynesians—neither contention is true, velocity can vary unpredictably • While velocity is not constant, changes do not appear to be obviously random or perverse Copyright © 2009 Pearson Addison-Wesley.
