Solutions

Expert Solution

Ans.

Private savings, PR = GDP - Consumption- Taxes

Public savings, PB = Taxes - Government Purchases

National Savings, NS = PR + PB

and National Income identity in a closed economy gives,

=> NS = Investment

Using above concepts,

a) PR = 1.5 trillion = 12 trillion - Consumption- 3.6 trillion

=> Consumption = $6.9 trillion

b) PB = 0.8 trillion = 3.6 trillion - Government purchases

=> Government purchases = $2.8 trillion

c) National Savings = PR + PB = 1.5 + 0.8 = $2.3 trillion

d) National Savings = Investment = $2.3 trillion
