conomics Consider 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 thisincrease, according to the IS-LM model will the IS curve shift up or down and byhow much?b) Considering your shift in the IS curve from part a, how should the Federal Reserveadjust the money supply if they want to keep interest rates constant?
Assume certain coutory economy consumption function =200+0.75(Y-T) given government purchase and Tax are 100 and investment function =100-25r real money demand =25y-100r money supply =1000 then find equilibrium income and interest rate when government purpose increase by 80 percent and tax increase by 70 percent draw IS and LM curve and by how much they shift ?
Given the following informations; Consumption(C) 800+0.9Y, Where Y-Income Investment (I) =8000-800r, where r=interest rate Money Supply (Ms) =28500 Demand for Money (Md) =0.75Y-1500r and if the autonomous Investment decreased then %3D income decreased and interest rate increased. income increased and interest rate decreased. O income decreased and interest rate decreased income increased and interest rate increased
The following equations describe a certain economy C=200+0.75Yd consumption function I = 100-50r Investment function T = 60+0.2Y Tax function G = 200 Government expenditure X = 100 Exports M = 100 + 0.02Y Import function MS = 2000 Money supply MD = 0.3Y-10r Money demand Required: Derive the IS and LM equations. Caleulate the equilibrium Y, C, T, M and I. General equilibrium occurs when IS and LM curves intersect. Explain the conditions to be satisfied at this intersection, and explain the causes of d'sequilibrium.
The following equations relate to a certain economy, peruse them and answer thefollowing questions.T = 0.75Y (tax rate)L= Y - 100r (Real money demand)M = 300 (Read money supply)C = 200 + 0.25Y d (Consumption function)I = 20 - 10r (Investment function)G = 30 (government purchases) i) Derive equations fro IS and LM curvesii) Determine the rand y pair at which the two markets are clearing iii) Compute the values of C, I and L.
Suppose 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.
