- Assume the following model of the economy: Y = C + I + G C = 120 + 0.5(Y - T) I = 100 - 10r G = 50 T = 40 Md = Y - 20 r Ms = 600 P = 2 Graph both the IS and the LM curves. Use r = 5, 10, 15 What are the equilibrium level of income and equilibrium interest rate?Question 2. Any help will be appreciated a. Identify each of the variables and briefly explain the meaning of each one. b. From the above list, use the relevant set of equations to derive the IS curve. Graph the IS curve on an appropriately labelled graph. c. From the above list, use the relevant set of equations to derive the LM curve. Graph the LM curve on the same graph you used in part (b). d. What is the equilibrium level of income and the equilibrium interest rate?How am I supposed to plot a figure thats not even on the graph and What are the answers to the questions that were not answered. These questions: Suppose that for every increase in the interest rate of one percentage point, the level of investment spending declines by $0.5 billion. Based on the changes made to the money market in the previous scenario, the new interest rate causes the level of investment spending to by . Taking the multiplier effect into account, the change in investment spending will cause the quantity of output demanded to by at every price level. The impact of an increase in government purchases on the interest rate and the level of investment spending is known as the effect. Use the purple line (diamond symbol) on the graph at the beginning of this problem to show the aggregate demand curve (AD3AD3) after accounting for the impact of the increase in government purchases on the interest rate and the level of…
- Consider an economy described by the following equations: Y=C+I+G C=100+.75(Y−T)C=100+.75(Y−T) I=500−50rI=500−50r G=125G=125 T=100T=100 Where: Y is GDP, C is consumption, I is investment, G is government spending, T is taxes and r is the rate of interest. Questions: a. What is the value of the multiplier? b. What is the equilibrium equation for Y? Show solution. c. Suppose the Central Bank policy is to adjust the money supply to maintain the interest rate at 4 percent,so r=4. What is the value of output? d. Assuming that no change in fiscal policy, what is the effect of a reduction in interest rate from 4 percent to 3 percent on equilibrium output. e. In this case, explain the policy that was used by the policymaker to target the aggregate demand.Q5.The following equations describe an economy. a.
