The Principal Method Used by the Federal Reserve to Change

The principal method used by the Federal Reserve to change the money supply is through open-market operations. Use the aggregate demand-aggregate supply model to illustrate graphically the impact in the short run and the long run of a Federal Reserve decision to increase open-market purchases. Be sure to label: i. the axes; ii. the curves; iii. the initial equilibrium values; iv. the direction the curves shift; v. the short-run equilibrium values; and vi. the long-run equilibrium values. State in words what happens to prices and output in the short run and the long run.
