4. Use AD and AS curves to explain the effects on the equilibrium price level and equilibrium level of output in the short run.
(a) A contractionary fiscal policy with the economy operating near full capacity.
(b) An expansionary monetary policy during a period of high unemployment and excess industrial capacity.
(c) A strong hurricane destroys energy plants which cause energy prices to increase, assuming that the Fed attempts to keep interest rates constant by accommodating inflation.
