Suppose that the equation for autonomous planned spending, Ap, is Ap=6200-200r and the value of the multiplier,k, is 2.5.
A) Derive the equation for the IS curve, Y=k*Ap. GRaph for interest rates 0 & 8, with intervals of one-half of a percentage point.
B) Suppose the equation for th LM curve is Y=13500+100r. Use this equation to explain the level of income at which there is a zero lower bound on the federal funds rate, the interest rate that the Fed controls.
C) Graph the LM curve for interest rates between & 8 with intervals of one-half a percentage point.
D) Suppose that the term premium is 1.0 percentage point and the risk premium is 2.0 percantage points. Use the M curve with the zero lower bound and the term premium and risk premium to graph the LM curve for the govenrment bond rate and the LM curve for the private bond rate at interest rates between 0 & 8, with intervals ofone-half of a percentage point.
E) Explain the equilibrium interest rates for the federal funds rate, the government bond rate, and the private bond rate are and what the equilibrium level of income is using the three graphs.
