Hey, I'm not too sure if this is right but you might be able to talk about some the following
- Australia's constant net primary income deficit due to
a)value of the exch rate (a depreciation will increase the $A value of debt, hence increase interest servicing costs
b) global and domestic interest rates as any changes to interest rates will again impact the value of debt service
c) Australia's large savings and invsmt gap as said above (we are historically low savers and we fund our capital invsmt through international borrowing (increasing interest repayments) or selling ownership in Australian assets (increasing foreign equity payments in the form of say dividends)
- BOGS deficit can occur from
a) level of economic growth especially high economic growth = more disposable income, more M and then BOGS deficit will occur and
b) changes in the international business cycle as poor growth in major trading partners means decrease in level of demand for X and therefore BOGS deficit and similarly we M more (BOGS deficit once again)
Best of luck with your essay, I think CAD, ext stability and net foreign debt are going to do my head in
