With the help of IS - LM curves explain the case where increase in government spending need not cause crowding out and if the budged deficit is monetized. (b) What is budget surplus? Explain why an increase in the government purchases will reduce the budget surplus by less than the increase in government purchases. Explain how the commitment to maintain a fixed exchange rate makes the money stock endogenous in a country with fixed prices and perfect capital mobility. Or What is real exchange rate? Why is it considered to be more relevant than nominal exchange rate? What happens to the IS curve if the real exchange rate R changes. S.G.G.S.C. HOUSE EXAMINATION 2007-08 1.

(iv) Find the fiscal and monetary policy multipliers. Answer any three of the following: (a) What is crowding out? Illustrate with the help of diagrams, the situations of full crowding out and zero crowding out. (b) Define “Neutral Money”. Show using IS and LM curves, why is money neutral under the classical supply model> (c) Using the IS LM framework show the effect of removal of investment subsidy on the level of output, interest rate and the level of investment. (d) Analyze the implications of a 1 year decrease in taxes for the path of debt and future taxes considering the cases of full repayment in year 2, full repayment in year t and debt stabilization in year t. Show how the aggregate supply curve can be obtained from the Phillips curve. Or Examine the implications of the sticky wage model for the short run aggregate supply curve. 4. Explain the monetary approach to the exchange rate. Or (a) Suppose the dollar interest rate and the pound sterling interest rate are the same at 5 percent per annum. What is the relation between the current equilibrium $/£ exchange rate and its expected future level? Suppose the expected future $/£, $1.52 per pound, remains constant as Britain’s interest rate rises to 10 percent per year. If the U.S. interest rate also remains constant, what is the new equilibrium $/£ exchange rate? (b) Are the Law of One Price and the Purchasing Power Parity the same? HOME EXAMINATION 2007-08, SRCC 1. Consider an economy with the following features: Consumption, Rs. C = 126 + 0.8Y(d) – 5R [Where Y(d) = disposable income, Rs., and R = rate of interest, percentage.] Bliss Point Studies 9891555578 18 Ravinder N. Jha 9811343411 B.A. (Hons) Economics-II Year Paper – V Investment, Rs. Tax, Rs. Government expenditure, Rs. Exports, Rs. Imports, Rs. [Where Y = income, Rs.] Real money demanded for transaction and precautionary purposes, Rs. Nominal money demanded for speculative Purposes, Rs. Price index, a number Full employment income, Rs. 2.

(b) If the Government reduces its expenditure by Rs. 20, what shall be the addition to the nominal supply of money to prevent the income from falling?, and (c) What shall be the change in tax to create full employment? Write down the equations for the dynamic aggregate demand and supply curves. Show how a one-time monetary expansion disturbs the initial equilibrium. Using a phase diagram, show both the long and short run effects. OR Use the aggregate demand and supply framework to show the effect of an increase in oil prices on output and prices in the short-run and long-run. Explain how either a fiscal expansion or an increase in the supply of money can influence the long-run -equilibrium. 3. Draw the net exports schedule in the price-output plane. How can devaluation in this situation deal with both internal and external balances, assuming that the Central Bank does not follow any policy to sterilize the effects of devaluation? OR Does a nominal devaluation always succeed in achieving a real devaluation? What are the related empirical issues? 4. Write on any two of the following: (a) Income version of quantity theory of money, (b) Wage-price flexibility and labour market, (c) Limitations of purchasing power parity, and (d) Harrod-Domar growth model. ***** Bliss Point Studies 9891555578 19 Ravinder N.
