(First-Difference Taylor Rule) Currently, the ination rate has been averaging at 4.0% for a few months, and real GDP growth rate is now 2.5% -- as the demand-side is too strong. The Federal Reserve is tasked to keep its \"Dual Mandate\" of ination rate at 2% and GDP growth rate at 2%. The previous-period Federal Funds Rate target range is 2.00-2.25%. EFFR sits at around 2.12-2.15% on the daily basis. IORB is at 2.2%. Short-term Treasury securities yield is at about 2.02-2.04%. Discount window rate is at 2.25%. Reserve supply is ample, with overnight reverse repurchase offered to non-depository institutions at 2.1%. Suppose the First-Difference Taylor Rule is given by: AFFRt = FFRt FFRt_1 = 0.1(1It 7f\") + 0.1(%Ayt %Ay*) where F F Rt is the current Federal Funds Rate, and F F Rt_1 is the previous-period Federal Funds Rate. Observe that the difference, or the change, is F F Rt F F Rt_1. Thus, the calculated result is the direction and amount that the Federal Funds Rate target range must change given the circumstances to achieve the desired target inflation and GDP growth.

(c) (5 points) In light of the current situation, what should the Federal Reserve do in its interest rate decision according to the Taylor Rule? Be specic in the action both qualitatively and quantitatively. (d) (7 points) How would the equation to this Taylor Rule change if the central-banker is more aggressive towards combating ination? Why so? (e) (0 points) Practice: With the prescribed policy decisions, explain and prescribe the open-market operations and all the relevant conventional monetary policy tools required to attain the Dual Mandate. Explain why each of the prescribed policy tools are required
