National Accounts, Income-Expenditure, Financial Markets, and IS-LM Model
National Accounts
GN = C + I + G + XQ, Y = C + S + T = C + I + G + XQ, (S-I) = (G-T) + (XQ), Yd = Y-T = C + S
Income-Expenditure Model (The Multiplier)
C = Co + C1(Yd), S = -Co + (1-C1)(Yd); On balance… Y = (1/(1-C1))(Co – C1*T + I + G)
Z = Co + C1(Yd) + I + G, C1 proportional to 1/(1-C1) consumption, 1-C1 proportional to savings
In equilibrium Z = Y, if Z > Y excess demand increases and, x is first consumed. Accumulated surplus stocks last, and consumption decreases.
