Question
20. Assume that an economy is characterized by the following equations:
а.
C=100+(2/3)(Y-T)
T=600
G=500
I=800-(50/3)r
M/P=M/P=0.5Y-50r
Write the numerical IS curve for the economy, expressing Yas a numerical function of G,
T, and r.
b. Write the numerical LM curve for this economy, expressing r as a function of Y and M/P.
C. Solve for the equilibrium values of Yand r, assuming P=1.0 and M=1,200. How do
they change when P=2.0? Check by computing C, I, and G.
d. Write the numerical aggregate demand curve for this economy, expressing Yas a
function of G, T, and MP.
