Explain the short-run effect of monetary policy that causes an increase in interest rates. As a result of higher interest rates, the O A. short-run aggregate supply curve will shift left. B. aggregate demand curve will shift left. O C. aggregate demand curve will shift right. O D. long-run aggregate supply curve will shift left. The new equilibrium will be O A. where the new aggregate demand curve intersects the original aggregate demand curve. B. where the original aggregate demand curve intersects the original short-run aggregate supply curve. O C. where the new aggregate demand curve intersects the original short-run aggregate supply curve. D. where the new aggregate demand curve intersects the original long-run aggregate supply curve
