the keynesian multiplier

The Keynesian Multiplier

Y = c (Y – t(Y) – T) + I + G + X – M

dY/dG = 1/(1-c+ct) dY/dT= -c/(1-c+ct)

ricardian equivalence

(y1 - t1 - c1) (1 + r) + (y2 - t2 - c2) = 0

(g1 - t1) (1 + r) + (g1 - t2) = 0

__________________________________

(y1 - c1) (1 + r) + (y2 - c2) = t1 (1 + r) + t2

(G) g1 (1 + r) + g2 = t1 (1 + r) – t2
