C = 100 + 0.5 - (Y – T) I= 200 – 1000 -r where Y is real output and r is the real interest rate. Government purchases and taxes are Ĝ = 300, T = 200. The LM (money market equilibrium) curve is P 101 where P is the price level and i is the nominal interest rate. The Central Bank (CB) is initially supplying M = 2000 units of money, and expected inflation is z“ = 0.02. Assume that the long-run equilibrium level of output is Ÿ = 1000. Short-run equilibrium output is initially at the same level (Y = 1000). Suddenly, news of a new world-beating super-vaccine raises the investment function to I = 250 – 1000 - r 1. Suppose the government (not the CB) wants to stabilise the shock in the long-run, meaning it wants the real interest rate to be the same as before the shock. Explain whether it should increase the government deficit (AĞ > AT) or reduce it (AĞ < AT), and how it works. 2. Suppose the government follows the policy you prescribed above. Explain how the economy would shift from its short-run to long-run equilibrium. In particular, what happens to output Y, the real interest rate r, and prices P during this process?

Consider a closed economy where the goods and money markets are described by the following relationships: C = 500+ 0.8(Y-T) I= 500 - 10r M/P = 0.1Y - 35r G = 800 T = 200 M = 1000 P = 2 Where C is planned consumption, I is planned investment spending, T' is government tax revenues, G is government purchases, M is the money supply, P is the price level and r is the interest rate.
Assume that investment, government expenditures, taxes are autonomous.C = 2000 + 0.65* (Y-T)I = 900 – 50iG = 400T = 1500M = 1000P = 2L = 0.50Y-25ia.What is the value of the sensitivity money demand to the level of income?b.What is the value of the nominal supply?c.What expression represents the IS curve?d.What is the equilibrium interest rate, i*?e.What is the equilibrium income, Y*?
Assume that the money demand function is (M / P)d = 2,200 – 200r, where r is the interest rate in percent. If the price level is fixed at P=2, and the Fed wants to fix the interest rate at 7 percent, it should set the money supply at: a. 2,000. b. 1,800. c. 1,600. d. 1,400.
Suppose the money demand function is Md/P = 1000+ 0.2Y - 1000 (r + π²). and Y = 2000, r = .06, π = .04, and Ms is 2600. Suppose the real interest rate rises to 0.11, and expected inflation rises to 0.09, but Y and Ms are unchanged. What would the inflation rate be? Select one: a. 4% b. 10% O c. 6% d. 8%
D7) IS-LM Model: Based on your understanding of the IS-LM model, graphically illustrate and explain what effect a monetary expansion will have on output, the interest rate, and investment. ( Properly)
Desired consumption is Cd = 100 + 0.8Y - 500r - 0.5G, and desired investment is Įd = 100 - 500r. Real money demand is Md/P = Y - 2000i. Other variables are re = 0.05, G= 200, Y = 1000, and M= 2100. b. Suppose the money supply increases to 2800. Find the equilibrium values of the real interest rate, consumption, investment, and the price level. (Assume that the expected inflation rate is unchanged.)
Suppose the interest rate that banks in Techland charge one another for overnight loans is 5 percent, the long-term nominal interest rate is 4.5 percent, and the long-term expected inflation rate is 3 percent. What is the long-term expected real interest rate? How will the long-term expected real interest rate be affected if the central bank of Techland starts purchasing government bonds from banks?
7) Assume that the economy is initially operating at the natural level of output. A simultaneous expansionary monetary policy and an increase in oil prices will cause which of the following? A) an increase in output and a reduction in the interest rate in the short run B) a reduction in output and an increase in the interest rate in the short run C) a reduction in output and a reduction in the interest rate in the short run D) an ambiguous effect in output and an increase in the price level in the short run E) an ambiguous effect in output and a reduction in the price level in the short run
Consider an economy characterised by: C = 500+ 0.8(Y-T) I = 400 120r +0.1Y G=300 T = 0.25Y L(r, Y) = Y - 300r M/P=600 13 where C, Y, I, G, T, r, L and M/P, denote consumption, output, investment, government spending, taxes, the interest rate, liquidity preferences and the real money supply, respectively. • Derive expressions for the IS and the LM schedules and plot the two curves. . Find the equilibrium interest rate and the equilibrium level of income. Derive the Keynesian multiplier and comment its properties compared to the standard case. . Calculate and interpret the effects on Y and r of an increase of money supply that bring M/P to 1200.
C = 100 + 0.5 - (Y – T') I = 500 – 1000 -r where Y is real output and r is the real interest rate. Government purchases and taxes are Ğ = 500, Ť = 100. The LM (money market equilibrium) curve is Y 5i where P is the price level and i is the nominal interest rate. The Central Bank (CB) is initially supplying M = 8000 units of money, and expected inflation is a = 0. Assume that the long-run equilibrium level of output is Y = 2000. Short-run equilibrium output is initially at the same level (Y = 2000). Suddenly, news of a new world-beating super-vaccine raises expected inflation to = 0.05. Question 5 Suppose that consumers finally decide to get rid of cash altogether, and only use debit cards. Nothing else changes, and the CB doesn't do anything either. What do you think will happen to money supply M and prices P in the short and long-runs? Does this change money demand?
On the basis of an assessment of the current and evolving macroeconomic situation, the Monetary Policy Committee (MPC) at its meeting today (December 4, 2020) decided tokeep the policy repo rate under the liquidity adjustment facility (LAF) unchanged at 4.0 percent.Consequently, the reverse repo rate under the LAF remains unchanged at 3.35 per cent and the marginal standing facility (MSF) rate and the Bank Rate at 4.25 per cent. Assess the present liquidity scenario in India and give your opinion about the impact of this reduction on money supply and also suggest other measures that RBI can take in recent times to maintain liquidity.
Exercise 1 cr+1 Consider the money supply Ms=mxB , m = cr+rr Assume that the demand for real money is given by the equation (M/P)d=0.25Y, and that the output has been growing 3% per year. Assume, further, that you have been called before Congress to testify about the long-run effects of increasing the growth of the money supply to 10 % per year. 1. State, compute and explain the long-run effects of this change on the inflation rate, on the nominal interest rate, on the real interest rate, on investment and on the real GDP. For each of them, argue both using the formulae that we studied and the macroeconomic dynamic beyond the effect. 2. Compute the implied money velocity. Suppose that the actual nominal value of the output (PY) is 1000, the value of the reserves is 50 and the toal value of the deposits is 75. Find the actual money multiplier. 3. State the different ways in which the central bank can achieve the change (+10%) in the money supply (think about the variables that can…
