Put another way increased spending that results from expansionary fiscal policy has crowded out investment spending and net exports which decrease because of the rise in the interest rate. This situation in which expansionary fiscal policy does not lead to a rise in output is frequently referred to as a case of complete crowding Panel b shows what happens when the Federal Reserve tries to eliminate high unemployment through an expansionary monetary policy increase in the money supply . Here the LM curve shifts to the right from LM1 to LM2 because at each interest rate output must rise so that the quantity of money demanded rises to match the increase in the money supply. Aggregate output rises from Y1 to Y2 the economy moves from point 1 to point 2 and expansionary monetary policy does affect aggregate output in this case. We conclude from the analysis in Figure 6 that if the demand for money is unaffected by changes in the interest rate money demand is interest-inelastic monetary policy is effective but fiscal policy is not. An even more general conclusion can be reached The less interest-sensitive money demand is the more effective monetary policy is relative to fiscal Because the interest sensitivity of money demand is important to policymakers decisions regarding the use of monetary or fiscal policy to influence economic activity the subject has been studied extensively by economists and has been the focus of many debates. Findings on the interest sensitivity of money demand are discussed in Chapter 22.
