Classical Economics • Classical theory argues that the economy automatically self corrects to full employment in the long run because of flexible prices and wages. Therefore there is no need for fiscal policy. • Classical economists believe in the quantity theory of money and that increases in the money supply cause inflation. 43 © 2014 Cengage Learning.

Keynesian Economics • Keynesian theory argues that the economy does not automatically self corrects to full employment in the long run and prices and wages are inflexible downward during a severe recession. Therefore there is a need for fiscal policy. • Keynesian economists believe that the velocity of money is unstable and that changes in the money supply affect interest rates and investment. 44 © 2014 Cengage Learning.

Monetarism • The investment demand curve is relatively flat or more horizontal, so the crowding-out effect is significant and fiscal policy is ineffective. • The Fed can not be trusted to control the money supply. Monetarists believe in the quantity theory of money and they advocate using a fixed money supply target. 47 © 2014 Cengage Learning. All Rights Reserved.
