If Taxes were cut by 1 trillion and the MPC was .70 by how much would total spending?
A.Increase in the first year with two spending cycles?
B. Increase in three years, with two spending cycles per year?
C. Increase over an Infinite Time Period per year?
1.
In the first cycle of first year=0.7*$1 trillion=700
billion
In the second cycle of first year=0.7*700=490 billion
Total=700+490=$1190 billion.
2.
Year | Spending cycle | Total Spending( billion) | Change in spending( billion) |
1 | 0.70*1=700 | 700 | |
1 | 2 | 490+700=1190 | 700*0.7=490 |
1 | 1190+343=1533 | 490*0.7=343 | |
2 | 2 | 1533+240.2=1773.1 | 343*0.7=240.1 |
1 | 1773.1+168.07=1941.17 | 240.1*0.7=168.07 | |
3 | 2 | 1941.17+117.649=2058.819 | 168.07*0.7=117.649 |
3.
Tax multiplier=MPC/(1-MPC)=0.7/(1-0.7)=2.33
Total change=2.33*1 =$2.33 trillion
