Lecture 13: Aggregate Supply and Aggregate Demand • Aggregate supply • Aggregate Demand • Shocks
e P = P (1+ ) F(1-Y/L,z) AS P e P Y Y n e P (t) = P(t-1) [for now] => AS: P(t) = P(t-1) (1+ ) F(1-Y(t)/L,z)
Aggregate Demand IS: Y = C(Y-T) + I(Y,i) + G LM: M = Y L(i) P LM’ [ P’ > P] i LM Y
AD:Y = Y(M/P, G, T) + + - P AD Y
Aggregate Demand - Aggregate Supply AS P AD Y
AD-AS: Canonical Shocks AS P AD Y Monetary expansion; fiscal expansion; oil shock (figs 7-9/7-10/7-11/7-12/7-13)
