Required:
a. Using the above data, determine GDP by both the expenditure and the income approaches and then determine NDP.
b. Now determine NI: first, by making the required additions and subtractions from GDP (Method 1), and second, by adding up the types of income and taxes that make up NI (Method 2).
c. Adjust National Income (from part b) as required to obtain PI.
d. Adjust PI (from part c) as required to obtain DI.

1. Expenditure approach

Gross domestic product = Personal consumption expenditures + Net private domestic investment + Consumption of fixed capital (depreciation) + Government purchases + Net export

Gross domestic product = $295 + $60 + 72 + $11

Gross domestic product = $438

Income approach

Gross domestic product = Compensation of employees + Rents + Interest + Proprietors' income + Corporate profits + Indirect business taxes + Consumption of fixed capital (depreciation) + Net foreign factor income earned

Gross domestic product = $273 + $14 + $13 + $33 +  $56 + $18 + $27 + $4

Gross domestic product = $438

NDP = GDP - Depreciation

NDP = $438 - $27

NDP = $411

b. NI = NDP - Net foreign income earned in U.S. - Indirect tax

NI = $411 - $4 - $18

NI = $389

So, both method will have same national income

c. Personal income = NI - S.S. - Corporate income taxes - Undistributed corporate profit + Transfer payment

Personal income = $389 - $20 - $19 - $21 + $12

Personal income = $341

d.  Disposable Income = PI - Personal tax

Disposable Income = $341 - $26

Disposable Income = $315
