Consider an island country called Chabotant. Suppose that in Year 1, disposable income in the country was $734 billion and consumption was $627 billion. Suppose further that in Year 2, disposable income is $815 billion. It has been observed that each time disposable income changes in this country by $100, consumption changes by $72. The level of saving in this country in Year 2 is:
Group of answer choices
$22.68 billion
$58.32 billion
$129.68 billion
$188 billion
$685.32 billion

Suppose in an economy, investment = $60, saving = $55, government spending+export = $100 and taxes+imports = $140. Then for this economy, total leakages exceed total injections by:
Group of answer choices
$15.
$25.
$35.
$40.
$45.
1) option 2)
Automatic stabilizers lead to rise in taxes during Expansion & Increase in Unemployment benefits during recession
.
2) option 3) 1000
MPC = .2, ∆S = .2*∆Y
= .2*5000
= 1000
.
3) option 3)
Each time , for ∆Y = 100, ∆S = 28
Saving in year 1, = 734-627
=107
∆ Y = 815-734
= 81
∆S = 81*.28= 22.68
Then in year 2, Saving = 107+22.68 = 129.68
.
4) option 5)
As AE< Y, so more is Produced, leading to rise in inventories, & firms overproduced
.
5) option 3) 35
Total leakages = S+M+T
= 55+140
= 195
Injections= I+G+X
= 60+100
= 160
So leakages exceed by 35
