Economics: Government Revenues Come From Total Income Taxes

Macroeconomics
1 a). Given the multiplier, the fiscal policy should aim at using expansionary policies to move out of recession. This would be done through increasing government expenditure that will lead to a rise in income levels through wages. Considerably, the government can lower tax rates to encourage investment. These polices lead to a rise in real GDP.
Multiplier = 1/(1-MPC)
MPC = 0.6
1/ (1 – 0.6)
= 2.5
Therefore, a one-unit change in government expenditure would lead to a 2.5 change in national income thereby increasing the total output or real GDP.
Thus, current G = 120, increase by 2.5 will be 120 * 2.5 = 300
The new G = 300 + 120 = 420
Using the tax multiplier; - MPC/ (1- MPC)
MPC = 0.6
= - 0.6 / 0.4
= - 1.5
A cut in the tax rate by 1.5 would close the recessionary gap to attain the $850 billion potential GDP.

Increased level of income would attract investments. However, the economy falls back to equilibrium with increased interest rate to lower the high i...
