Determination Of CF, NX And ER With The Help Of IS- LM Model:
IS equation: Y = C(Y – T) + I(r) + G + NX (є) …(1)
LM equation:
M/P = L(r, Y) …(2)
Capital inflows takes place Reason: foreign investors will find it profitable to invest here because they will get a high interest rate on the loan given.
Result:
CF will decrease
Similarly if r falls; r < r*
ADVERTISEMENTS:
vice versa will take place.
Relation between NX and ER:
(i) Equilibrium interest rate is determined where:
ADVERTISEMENTS:
IS = LM
IS = LM at point E
... Equilibrium interest rate → r1
Equilibrium income level → Y1
(ii) At interest rate – r1
CF is CF1 (Fig. b 17.5)
When CF is CF1
NX is NX1(Fig. c 17.5)
ADVERTISEMENTS:
ER is є1
And thus equilibrium CF is CF1
Where: NX is NX1 and ER is є1
