Table 1 shows some items in Us National Income and Product Accounts in 2005.
Use the table to answer the following problems:
1. Use the expenditure approach to calculate US GDP in 2005.
2. What was U S GDP as measured by the income approach?
3. By how much did gross product and net product differ in 2005?
4. Calculate US GNP and US national income.
Item Amount (trillions of dollars )
Consumption expenditure C 8.7
Government expenditure G 2.3
Indirect taxes less subsidies ( NITX) 0.8
Depreciation ( D) 1.5
Net factor income from abroad 0.1
Investment I 2.0
Net exports NX − 0.7
Statistical discrepancy 0
Answers:
1. US GDP in 2005 by expenditure approach
GDP= C + I + G + NX
GDP= 8.7 + 2.0 + 2.3 + (-0.7) = 12.3 trillions of dollars
2. US GDP in 2005 by income approach=
US GDP by expenditure approach - Statistical discrepancy=
12.3 trillions of dollars - 0 = 12.3 trillions of dollars
(Note: We have not enough information to calculate US GDP in 2005 by income approach using the 3 steps.)
3. Gross product and net product differed in 2005 by Depreciation.
Gross product = net product + Depreciation.
Gross Product= net product + 1.5 trillions
Therefore, Gross product was greater than net product by 1.5 trillions of dollars.
4. US GNP = US GDP by expenditure approach + Net factor income from abroad
US GNP= 12.3 + 0.1= 12.4 trillions of dollars
US national income=
US GNP - Depreciation – Statistical discrepancy = 12.4 – 1.5 – 0 = 10.9 trillions of dollars
