Step by step
Solved in 3 steps
- Consider the following closed economy in the context of the IS-LM model. The consumption function (C), the investment function (I), government purchases (G), taxes (T), the money demand function (MD), money supply (M) and the price level (P) are given as: C = 500 + 0.75(Y - T)I = 1000 - 300?G = 1000T = 1200MD = 0.5Y - 200rM = 5000P = 2 (a) Write down the equations for the IS curve and LM curve. Show your workings. (b) Solve for the short-run equilibrium output and interest rate. (c) Suppose government purchases falls, with ΔG=-175. (i) Using the Keynesian cross model, calculate the change in equilibrium output. (Hint: Use the government purchases multiplier.) (ii) Would your answer be the same if you calculate the change in equilibrium output using the IS-LM model? Briefly explain your answer. (e) Suppose the price level falls. Using an appropriate IS-LM diagram, illustrate the short-run impact of the fall in price level on the equilibrium interest rate and output. No written…With respect to the IS/LM model, which of the following statements is false? Interest rates and output are the endogenous variables The position of the IS curve is given by α (alpha) The IS/LM model is an extension of the income-spending model The LM curve maps interest rates and output such that the money market clears Along the IS curve, planned aggregate spending is equal to incomeConsider a consumption function of C = 0.75 (Y – T). a) If government spending increases by $300 and there is a tax hike of $500 to fund this increase, according to the IS-LM model will the IS curve shift up or down and by how much?b) Considering your shift in the IS curve from part a, how should the Federal Reserve adjust the money supply if they want to keep interest rates constant?
- Which of the following statements is false? The larger the expenditure multiplier, the steeper the IS curve The LM curve is positively sloped because higher interest rates induce higher income levels in order for the money market to remain in equilibrium The adjustment mechanism in the Keynesian income-expenditure model is an unplanned rundown or accumulation of inventories The aggregate expenditure function relates planned spending to income A position that is to the left and below the IS curve indicates that there is excess demand for goods and servicesSuppose that economy of Portugal is characterized by the following C = 200 + 0.5 (Y - T) Represents the consumption function I = 600 – 30 r represents the investment function G = 300 represents the public spendingT = 300 represents the level of taxation (m/p)d = y - 40 r represents the money demand function (m/p)s = 1500 r represents the real money supply d Y represents the global output Find the IS curve the LM curve and deduce the equilibrium level of interest rate equilibrium level of income. The government increases the money supply by 100. How does it affect the equilibrium level of income? Justify your answer. Calculate the new equilibrium...

How much should government spending change by? With the help of graphs, explain very carefully, the impact of this policy on the economy. f) An…
- Outline the main concepts of the Liquidity Preference Theory proposed by John Maynard Keynes and discuss its applicability to the Caribbean region.A Keynesian economy is described by the following equations. Consumption Cd = 250 + 0.5(Y - T) - 250r Investment Id = 250 - 250r Government purchases G = 300 Government taxes T = 300 Real money demand L = 0.5Y - 500r + πe Money supply M = 3000 Full-employment output Y = 1250 Expected inflation πe = 0 (HINT a: The expected rate of inflation is assumed to equal zero so that money demand depends directly on the real interest rate, which equals the nominal interest rate. Domestic Savings, Sd =Y - C - G. In equilibrium set domestic savings equal to domestic investment, so Sd = Id) Calculate the values of the real interest rate (r), consumption (Cd), and investment (Id) for the economy in general equilibrium.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.

The consumption and investment functions are given by C = 200 + 0.25(Y - T) I = 150 + 0.25Y – 1000i. and suppose that government expenditures and taxes are given by G = 250 and T = 200. respectively. Let real money demand be given by MIP = 2Y – 8000i, and let the initial interest rate be ig = 0.05. Solve for the equilibrium values of output and real money supply. (b) Solve for the equilibrium values of C and I, and verify that consumption, investment and government expenditures indeed add up to output Y. (c) Now suppose that interest rate is cut to ig = 0.03. Solve for the new equilibrium values of Y, M/P, C and I. What are the effects of this change on the economy? Provide brief intuition. (d)" Set the interest rate back to ig = 0.05.
