请教高手！Curriculum level2 2012 Economics P695习题第六题的答案的解释是“government plus private investment total more than net international borrowing of 3153million. Net international borrowing is equal to the current account deficit(imports less exports)because the official settlements account balance is zero" 我实在是看不懂其道理，课文里貌似也没讲到。
网上一些地方都在问，但貌似无人解答。作者: jsyang888 时间: 2012-5-24 18:53
Section 19, Econ Problem #6
Based on the information provided by the sell-side Analyst for Bricania’s trade, private sector, and gov expenditures, including Exhibit 1, which of the following satements is most likely correct:
Exhibit 1:
Gov expense for defense, public structures: 4500
Net tax receipts: 12,387
Expenditures: 14673
Surplus (deficit): (2,286)
Private Sector Savings: 11,398
Private Sector Investment: 12,265
Surplus (deficit): (867)
Exports: 6,203
Imports: 9,356
Surplus (deficit): 3,153
Answer: Bricania’s (country) international borrowing is financing private and public investment, not consumption. Goverment plus private investment (4500 + 12265) total more than net internation borrowing of 3,153. Net international borrowing is equal to the current account deficit (imports less exports) because the official settlements account balance is zero.
How did they draw this conclusion that international borrowing is financing private and public investment and not consumption?作者: jsyang888 时间: 2012-5-26 11:19
current account + capital account +financial account+official settlements account = 0
因为official settlements account=0
所以current account + capital account +financial account=0
所以current account=-capital account -financial account
net borrowing 为负作者: jsyang888 时间: 2012-5-31 07:49
（1）所以capital account +financial account 就是 net international borrowing 了？ （2）但如何能看出 international borrowing is financing private and public investment, not consumption？

Consumption+Gov Exp+Net Export+Investment= GDP (per expenditure measure of GDP)
move Net Export to the other side and change (- Net Export) to (Net Import) to get
C+G+I=NI+GDP, which means domestic generated income and net import are financing the three expenditures, C+G+I.
Since NI<G+I, C is necessarily financed by GDP. (Of course, the problem is assuming NI goes to G & I first, then any remaining surplus goes to C, which to me makes no sense at all)作者: jsyang888 时间: 2012-6-1 09:31
I agree with you. I can't see why Net international borrowing have to go to"government's and private investment' first.
