G – T = (S – I) – (X – M) “A fiscal deficit [(G – T) > 0] implies that the private sector must save more than it invests [(S – I) > 0] or the country must run a trade deficit [(X – M) < 0] with cor- responding inflow of foreign saving, or both.” I srsly don’t get this. Why does (S-I) have to be greater than zero? (S-I) and (X-M) both can be negative and have (G-T) still negative. Does anyone have good way of memorizing this? Thank you
S= I + (G - T) + (X - M)
so if,
S = I +(10 - 5) + (20 - 25)
Why is it
S = I + (-5) + (+5)
WHY ?
how is (10 - 5) = -5???
Okay, so the country currently has a fiscal deficit (spending more than receiving, G > T ) . Let’s give this net balance 5.
Therefore the other half of the equation, (S – I) – (X – M) MUST equal 5.
Therefore, as you can see ( S - I ) needs to be a positive figure ( i.e greater or equal to 5) as we now have to subtract ( X - M )
I think you understand it, just mabye needs a couple of days to get your head around it. Perhaps find a couple practise questions from Qbank as that will also explain the answers more clearly than I have,
But if you have negative (X - M), then it would add to (S - I)…
Because the trade deficit will be a minus. Therefore it it minus a negative number = positve number.
I think that’s right. Someone please correct if not.
screw it.
gonna skip this LOS and guess it on exam
i’m so confused
G – T > 0; it’s positive.
If S – I < 0 (negative) and X – M > 0 (positive), then (S – I) – (X – M) is negative – positive = negative; thus, it cannot equal G – T (positive).
So . . . either S – I > 0, or X – M < 0.
That’s what they said.
No. But the above is a good way of understanding it so that you don’t have to memorize it.
You’re welcome.
