Md=25y-80r,Ms=2400, p=2
a) Find equilibrium output equation. And Y* when r=12%
b) Find LM curve equation
c) Find slope of LM curve.
d) MS increased to 3000
3. Find equilibrium r
4. Find equilibrium y
Solution
Md=Ms
"2400=25Y-80r"
"r=\\frac{25Y-2400}{80}" The LM equation
"25Y=2400-80r"
r=12%
"Y=\\frac{2400-9.6}{25}= 95.6"
When Ms is increased to 3000
"3000=25y-80r"
"80= 25y -3000"
LM equation
"\\frac{25}{80}-\\frac{3000}{80}"
Equilibrium when r=12
"25Y = 3000-80(0.12)"
"Y = 119.6"
c)
