The following equations describe economy Y. All figures except the parameters are in millions of dollars.

C = Co + cYD (Private Consumption by Households)

YD = Y + TR - T (Private disposable income)

T = To + tY (Total taxes)

G = Go (Government Expenditure)

TR = TRo (Transfer Payments)

I = Io + zY (Private investment)

X = Xo (Total Exports)

IM = IMo + mY (Total imports)

SP = YD - C

SG = T - (G + TR)

SF = IM - X

Y = C + I + G + X - M (Equilibrium condition)**

Endogenous Variables: C, YD, T, IM, I and Y

Exogenous Variables: Co = 450, To = 80, Io = 400, Go = 250, TRo = 250, Xo = 200, IMo = 110

Parameters: c = 0.68, t = 0.16, z = 0.12, m = 0.30
