Was just scrolling thru here and saw this...I agree, I took increased business investment to mean increased domestic investment, hence less need to seek overseas investment and therefore less NPY debits, then combined with less portfolio investment obvs means less NPY debits. Was definitely ambiguous tho but I ruled out the lower import prices one (after initally thinking it was right) bc that would just increase demand for imports and worsen net exports, i guess kinda cancelling out the depreciation of currency. Could be overthinking it tho. Someone tell me if im wrong...wait i just saw this, pre sure it was D cause it was a hypothetical economy so u have to rely on theory
