3. Suppose the monetary policy curve is given by r = 1.5 +0.75 , and the IS curve is given by Y = 13- a) Find the expression for the aggregate demand curve. b) Calculate aggregate output when the inflation rate is at 2%, 3%, and 4%. c) Plot the aggregate demand curve and identify the three points from part (b).
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.
Most modern central banks engage in inflation targeting instead of aiming at some nominal level of GDP, some exchange rate level, or the unemployment rate. Most central banks choose a rate of between 2-3% annual inflation and periodically adjust interest rates via open market operations and discount rate changes. A question, however, is whether they should focus on targeting core inflation, which excludes food and energy and a few other very volatile items, or use a headline inflation rate that includes all items in a defined consumer basket of goods. The majority of central banks focus on core inflation. 1. Can you name a few reasons why overreliance on core inflation can be misleading? 0
Hyperinflation is caused by a constant increase in the money supply. a high rate of growth in the money supply. real GDP growing more rapidly than the money supply. the money supply growing more slowly than GDP.
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)
The following equation is a money demand function Md /P = f(y,I) a. Explain the equation b. Show that velocity of circulation of money is not constant c. What will happen to money demand if the nominal interest rate declines?
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.
According to Keynes, which of the following information about the money market is wrong?A) The cost of giving up liquidity is interest.B) The money supply graph is steep.C) The equilibrium interest rate drops as a result of the expansive money supply.D) When the interest rate is above the equilibrium interest rate, a money supply surplus occurs in the economy.E) There is an inverse relationship between money demand and income.
