5. Suppose that we have a partial sticky price New Keynesian model. Suppose that the economy is hit with an increase in At+1. Suppose that the central bank wants to adjust the money supply in such a way that the real wage does not change in response to this shock. How must the central bank adjust policy in response to the increase in A+1 in order to achieve this end? How does output react to the change in Aț+1 if the central bank follows such a policy? How does this change in Y; compare to a world in which the money supply is exogenous (i.e. does not react to the increase in Af+1)?

a) Which of the follwing monetary policy actions can be used to close an inflationary gap?O No change in the money supply to keep interest rates constant.ODecrease the money supply to decrease interest rates,OIncrease the money supply to increase interest rates.O Increase the money supply to decrease interest rates.O Decrease the money supply to increase interest rates. b) Assume the economy is initially at full-employment equilibrium. Suppose the economy slows down and uncertainty increases, reducing consumption and investment expenditures, in the short run, this shock willcause the economy to fall below full enployment. To move the economy to a full-employment equilibrium, the Fed could:O. decrease government spendingO. increase corporate tax ratesO. lower the federal fund rate targetO. increase government spending O. raise interest rates
Suppose an economy is in long-run equilibrium.a. Use the model of aggregate demand andaggregate supply to illustrate the initialequilibrium (call it point A). Be sure to includeboth short-run aggregate supply and long-runaggregate supply.b. The central bank raises the money supply by5 percent. Use your diagram to show whathappens to output and the price level as theeconomy moves from the initial equilibrium to thenew short-run equilibrium (call it point B).c. Now show the new long-run equilibrium (call itpoint C). What causes the economy to move frompoint B to point C?d.

On June 5, 2003, the European Central Bank acted to decreasethe short-term interest rate in Europe by half a percentagepoint, to 2 percent. The bank’s president at the time, WillemDuisenberg, suggested that, in the future, the bank could reducerates further. The rate cut was made because European coun-tries were growing very slowly or were in recession. What effectdid the bank hope the action would have on the economy? Bespecific. What was the hoped-for result on C, I, and Y?
In regard to monetary policies, nonactivists have various proposals. True or False: Some nonactivists believe in the Taylor rule, which suggests that the annual money-supply growth rate should be based on the growth rates of velocity and Real GDP to ensure that the price level does not fluctuate. O False O True Which of the following statements best explains the difference between the Taylor rule and the two other nonactivist rules (the constant-money growth rate rule and the predetermined-money growth rate rule)? O The Taylor rule does not take into account the stability of prices. O The Taylor rule suggests how much the money supply should grow. O The Taylor rule does not take into account the current state of the economy. O The Taylor rule is not a derivation of the equation of exchange.
