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:

Determination of CF 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
