(a) Suppose the Federal Reserve Bank is pursuing a contractionary monetary policy. Using a graphical analysis, show the effects of this policy on the equilibrium interest rate, investment and output. Make sure you clearly label all the curves in your graphs and the initial and final equilibria.

Make sure you clearly label all the curves in your graphs and the initial and final equilibria. Is there any crowding-out due to the contractionary fiscal policy?
