Consider a closed economy where the goods and money markets are described by the following relationships: C = 500+ 0.8(Y-T) I= 500-10r M P 0.1Y - 35r G = 800 T = 200 M = 1000 P = 2 Where C is planned consumption, / is planned investment spending, T is government tax revenues, G is government purchases, M is the money supply, P is the price level and r is the interest rate.

Question
Consider a closed economy where the goods and money markets are described by the following relationships:
C = 500+ 0.8(Y-T)
I= 500-10r
-
M
P
=
= 0.1Y - 35r
G = 800
T = 200
M = 1000
P = 2
Where C is planned consumption, / is planned investment spending, T is government tax revenues, G is
government purchases, M is the money supply, P is the price level and r is the interest rate.
b) Calculate the equilibrium value of output Y and interest rate r (round off your answers to one decimal point).
Compute also the level of consumption and investment spending in equilibrium and check whether the actual
level of spending matches the equilibrium level of output.
d) If the Central Bank intends to pursue monetary policy in order to restore output to the same level before the
fall in consumer confidence, how much should money supply change by? Use graphs to show the change in
the economy and explain very carefully the monetary transmission mechanism
e) Suppose that, instead of relying on monetary policy, the government intends to take an active role in
restoring the economy to the original equilibrium by pursuing an expansionary fiscal policy. How much should
government spending change by? With the help of graphs, explain very carefully, the impact of this policy on
the economy.
