Question
Use the following versions of the IS-LM model to answer all sections: Question: a. Determine the IS function and its slope. b. Determine the LM function and its slope.
Consumption:
C = 1400 + .75*Yd + .08*(M/P)
Net Exports:
NX= 400 - .25*Yd – 10*r
Taxes:
T= -200 + .2*Y
Yd = Y - T
| = 140 – 30*r
G = 200 - .2*(Y – Yp)
AD = C + |+ G + NX
Disposable Income:
Investment:
Governmental Purchases:
where Yp = potential GDP
Aggregate Demand:
Goods Market Equilibrium
Y = AD
Money Demand:
Money Market Equilibrium
Md/P = .25*Y – 50*r
M = Md
