Q

Ø If the reserve bank changes the OCR to increase money supply – this will put

17
Q

Y > YBAR

A

will mean that prices will rise – this will lower real money supply – which will
lower the real money demand – causing the LM to shift back to the original

18
Q

Can the reserve bank affect the NX and exchange rate by changing the OCR?

A

short
run yes – long run no

19
Q

There is a country risk

A

– that borrowers will default due to political/economic turmoil – lenders require higher interest to compensate risk

20
Q

Expected exchange rate changes – if the exchange rate falls then borrowers will have
to pay

A

higher interest to compensate for the fall

21
Q

r = r* + θ

A

which represents the risk premium

22
Q

Y =

A

C + I (r* + θ) + G
+ NX

23
Q

M/P=

A

=L (r* + θ, Y)

24
Q

If theta increases this will mean that

A

interest rates rise so investment falls – and
IS will shift the left

so money demand falls and LM will shift the right

25
Deriving the AD curve
we use the real exchange rate instead of nominal as before we assumed prices are constant – now they are variable
