- QUESTION TWOConsider the consumption function is given byC = 200 + 0.75YDWhere YD is disposable income Suppose that the economy faces an investment function of the formI = 200 – 25r.Suppose further that G =T = 100 and the money demand function takes the form(M/P) = Y – 100r.The money supply M is 1,000 and Price level P is 2Required:(i) Formulate the IS equation and the LM equation.(ii) Find the equilibrium interest rate and the equilibrium level of income. (iii) If government expenditure increases by 50, by how much does the IS curveshift? (iv) If the money supply increases by 200. How much does the LM curve shift?Consider an economy called Xanadu for which desired aggregate consumptiondepends on income, Y. and the real interest rate, r, according toCd =100+0.7Y - 200r.Xanadu's GDP is Y = 1000 and government spending on goods and services is G=180. Xanadu's desired future capital stock is given byK* = 140 - 100ucwhere luCdenotes the user-cost of capital. The price of capital is PK =2, thephysical depreciation rate is d =0.1 and the existing capital stock is K0= 50. Trapital stock between any period t and the following period t+1 evolves accordng toKt+1 = It+(1-d)Kt where It the level of investment. Assume throughout that net factor payments from abroad (NFP) is equal to zero.Suppose instead that Xanadu is a small open economy facing a world interest rate of 1%. It follows that Xanadu's current account position is equal toA) -16B) -51C) -6D) -8Suppose 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 known as the by at every price level. The impact of an increase in government purchases on the interest rate and the level of investment spending is effect. Use the purple line (diamond symbol) on the graph at the beginning of this problem to show the aggregate demand curve (AD3) after accounting for the impact of the increase in government purchases on the interest rate and the level of investment spending. Hint: Be sure your final aggregate demand curve (AD3) is parallel to AD₁ and AD₂. You can see the slopes of AD₁ and AD₂ by selecting them on the graph.
