Explain graphically the determination of equilibrium GDP for a private economy through the aggregate expenditures model. Now add government purchases (any amount you choose) to your graph, showing its impact on equilibrium GDP. Finally, add taxation (any amount of lump-sum tax that you choose) to your graph and show its effect on equilibrium GDP. Looking at your graph, determine whether equilibrium GDP has increased, decreased, or stayed the same given the sizes of the government purchases and taxes that you selected.
Use the following information on economy X to answer the questions below.Consumption function:
C = 250 + 0.8Y
Investment spending: I = 150
Government spending: G = 500
Exports of goods and services: X = 200 Imports of goods and services: Z = 150 Proportional tax rate: t =25%Full employment level of income = 3575
1. Calculate the equilibrium income for the economy. 2. Calculate the change in government spending required to reach (3) full employment level of income.
Graph the following situation. Suppose the economy is in a recessionary gap and GDP is in equilibrium at $500B and potential GDP is $700B. In this economy the MPC in this economy is .9, how much Government spending is needed to bring the economy to potential GDP?
