Assume C0 = 200, I0 = 200, G0 = 100, X0 = 100, M0 = 100, T (taxes)= 100
Marginal propensities: c1 = 0.8, i1 = 0.1, m1 = 0.15
Aggregate Expenditure: E = C0 + c1(Y - T) + I0 + i1Y + G0 + X0 - M0 - m1Y
Calculate aggregate expenditure in equilibrium where E=Y
Calculate and interpret the individual and combined effects of changes to X0 and M0 such that X0 = 150 and M0 = 150 and all other variables remain unchanged.
Also, calculate and interpret the values of the multiplier.
