Quick questions on The current account deficit and external stability debate: HSC Economics Topic 2

Economist John Pitchford developed the "consenting adults" thesis in the 1980s in response to concern that Australia's persistently large CAD signalled a policy failure requiring government correction. Pitchford argued the opposite: a CAD driven mainly by private-sector borrowing and investment decisions does not threaten external stability and does not require government intervention.

A CAD must be financed by net capital inflow (recall the identity CA + KAFA = 0). Financed year after year, this inflow accumulates into a growing stock of net foreign debt and net foreign equity, recorded on Australia's international investment position.

Servicing this accumulated stock (interest and dividend payments to non-residents) appears in the current account as the net primary income deficit. A larger stock of foreign liabilities means larger servicing costs, which widens the CAD further even with no change in trade flows, a self-reinforcing loop. The debt-servicing ratio (interest payments on foreign debt as a percent of export earnings) is the key indicator: a rising ratio means a growing share of export income is committed to servicing old debt rather than funding new consumption or investment.

If foreign lenders lose confidence, for example after a sharp fall in the terms of trade or a sovereign credit-rating downgrade, capital inflow can reverse abruptly. This "sudden stop" forces a rapid currency depreciation and/or a forced cut in domestic absorption (consumption plus investment plus government spending) to restore external balance. Episodes broadly of this kind are commonly cited from the Latin American debt crisis of the 1980s and the Asian financial crisis of 1997 to 1998, where countries reliant on foreign capital inflow faced abrupt reversals.

Under Pitchford's view, government should not try to shrink a privately-funded CAD (for example, via a tighter budget stance aimed specifically at the external balance), since doing so may block profitable private investment without reducing genuine risk.

A top-band "analyse"/"evaluate" response explains why a privately-funded CAD is less risky (risk internalisation, market discipline), then shows the thesis's limits (public financing, accumulated debt-servicing costs, sudden-stop vulnerability), then reaches an explicit judgement.

"Australia's CAD improved" is weak; "Australia's CAD narrowed from about minus 6% of GDP in 2007 to 2008 to a surplus of around plus 2.5% of GDP in 2021 (RBA/ABS)" earns the application mark.
