QUESTION. AD-AS Consider a theoretical framework where the short-run AS describes, as usual, a positive relationship between the price and output levels. The AD is obtained by combining the following equations:
C = c0 + c1(Y − T)
I = d0 − d2i
T = t0 + t1Y
L = f1Y − f2i
with G = G0 and M = M0.
Starting from a long run equilibrium allocation, assume that autonomous consumption
decreases, ∆c0 = x < 0
a) Represent graphically (AD-AS plot) the short run effect indicating if and how output
and price change
b) Moving from the starting long-run equilibrium to the short-run equilibrium, indicate if
and in which direction the following variables have changed: i interest rate, I invest-
ment, C consumption, T taxation, G public expenditure, w nominal wage
