Answer 1

Answers

Private sector savings = $150

public sector savings = -$250

National savings = -$100

Solutions

Private savings are the private sector savings. That is, savings by the households and private firms.

Private savings = Y - ( T + C)

= Yd - C

= S

= $150

Public savings are the government savings. These savings represent the excess of government expenditure (G) over tax revenue (T).

Thus,

Public savings = T - G

= $250 - $500

= -$250

The public savings is negative. This means that government expenditure exceeded revenue (tax revenue) hence a deficit. Thus, there is a government budget deficit of $250.

National savings combine the private sector savings and the public sector savings.

National savings

= private savings + public savings

= $150 + (-$250)

= $150 - $250

= -$100

The national savings is negative meaning that the nation as a whole has a deficit; national spending exceeded national income. This negatively impacts money in circulation, availability of loanable funds, and economic prosperity as it represents a withdrawal from the circular flow of national income.
