(a) Consumers become less confident about the future, spending less and saving more [5]
(b) A tax reform increases incentives for firms to invest in new factories

(d) The central bank doubles the money supply
[5]

Question 4
[25 marks]
Consider hypothetical small open economy described by the following equations:
C = 50 + 0. 75(Y - T)
I= 200-20r
NX = 200- SOE
M
-p= Y - 4 0 r
G = 200
T = 200
M = 3000
P=4
r*= 5
(a) Derive and graph the 1s· and LM . curves
[5]
(b) Calculate the equilibrium exchange rate, income and net exports
[6]
(c) Assume a floating exchange rate: Calculate what happens to the exchange rate, income, net
exports and money supply if the government purchases increase by 50
[7]
(d) Now assume a fixed exchange rate. Calculate what happens to the exchange rate, income,
net exports, and the money supply if the government purchases increase by 50
