(1) Given a hypothetical consumption function of the form:
Y = C + I0 + G0 ,C = α + β Yd Where: Yd = Y – T, Y = Income, T = Taxes
Government spending and investment are exogenously determined at G and I respectively. Assuming this model represent a three sectors economy, determine Investment multiplier, Government spending multiplier and Tax multiplier. If there is an increase in marginal propensity to consumer, how will this affect the national income?
