Whew. To answer this problem, I needed to make some assumptions. First, the difference between government outlays and government purchases is transfer payments. Transfer payments are not components of GDP. Second, income to foreigners is income generated in the country but flowing out of the country. Such moneies are included in GDP but not included National Income.
1) Inventory investment is the net change in inventories. Inventories changed from 10 to 5, a net change of -5. (So, total investment (I) is planned business fixed and residential investments plus the net change in inventories)
2) Net Exports -- you got right
3) GDP = C+I+G+(X-M)
= 140 + (27-5) + 65 + (21-17)
In addition, GDP = National Income + depreciation (D) + indirect business taxes (IBT). And National Income (NI) is labor income plus capital income minus income going to foreigners (plus income by residents living over seas, which is not mentioned in this problem).
So, NI = 126 + 70 - 5 = 191
GDP = NI + D + IBT = 191 + 12 + 28 = 231
4) Statistical discrepancy = none.
5) National savings is Y-C-G = 231-140-65 = 26
Note I+(x-m) = 27-5 + 4 = 26.
I hope this helps.
thank u for ur help. for statistical discrepancy i got 211-201=10
i thought its bifference b/w calculation of GDP and the method of income of factor of production(Labor income+Capital Income+Net income foreigners.. lemme know if im wrong!!
thnx again for ur help
