In a certain economy marginal propensity to save is s = 0.2, c = 1 - s = 0.8 and the autonomous consumption is Ca = 400 a) consumption function is C = Ca + c(Y - T) = 400 + 0.8(Y - T) b) multiplier m = 1/(1 - c) = 1/(1 - 0.8) = 5. If the government expenditure were to increase by 50% then the resultant change in national income is 50%*5 = 250%.
