Answer:
a. Public saving = Tax collections - Government purchases - Transfers and interest payments
=195 - 160 - 110
= -75
Private saving = Household saving + business saving
= 200 + 400
= 600
National saving = Private saving + public saving
= 600-75
= 525
National saving rate = National saving/GDP
= 525/2500
=0.21
= 21%
b. Private sector disposable income = GDP - Taxes + Transfers
= 6150 - 1425 + 400
= 5125
Private sector savings = Disposable income - consumption
= 5125 - 4520
= 605
Public savings = Govt budget surplus = 100
National savings = Private savings + Govt savings
= 605 + 100
= 705
National savings rate = National savings / GDP
= 705 / 6,150
= 0.1146
=11.46%
c. GDP = Consumption + investment + Government purchase + Net Export
= 4,300 + 1,000 + 1,000 + 6
= 6,306
Govt savings = Taxes - Transfers - Govt purchases
= 1,575 - 500 - 1,000
= 75
Private sector disposable income = GDP - Taxes + Transfers
= 6,306 - 1,575 + 500
= 5,231
Private sector savings = Disposable income - consumption
= 5,231 - 4,300
= 931
National savings = Private savings + Government savings
= 931 + 75
= 1,006
National savings rate = National savings / GDP
= 1,006 / 6,306
=0.1595
= 15.95%
