c) What happens to the IS curve if the marginal propensity to consume (MPC) suddenly jumps to 0.6? Why? Does the slope of IS curve changes? Does such this lead to the shift of IS curve?

Question

Just need help with the questions after C

a) Derive the IS curve.
b) What happens to the IS curve if G increases by AG = 100 financed with a corresponding
increase in T by AT = 100? Why? Does the slope of IS curve changes? Does such policy
lead to the shift of IS curve?
c) What happens to the IS curve if the marginal propensity to consume (MPC) suddenly
jumps to 0.6? Why? Does the slope of IS curve changes? Does such this lead to the shift
of IS curve?
d) Derive the LM curve.
e) Find the equilibrium values of Y and r.
) The central bank wants to increase GDP by 20 by changing the money supply. What
should be the new real money supply?
g) Suppose the demand for money becomes less sensitive to changes in the interest rate.
What should happen to the money demand equation provided above? What would change
in that equation and in what direction? Would that make the fiscal or the monetary policy
more potent? Would you recommend a fiscal or a monetary policy to get the economy
out of recession? Provide two graphs showing how an expansionary fiscal and monetary
policy, respectively, work an extreme case of zero money demand sensitivity.

Consider an economy characterized by the following goods and services market:
C = 200 + 0. 5 (Y – T)
I= 150 – 5r
G = 200
T = 100
And the following money market:
= 0.25Y – 0.5r
M*
235
