(a) Using the relationship S = Yd– C we substitute the consumption function and obtain, 5 = Yd– (310 + 0.7 Yd) = Yd– 310 – 0.7 Yd, Collecting terms gives the saving function, With no direct taxation, Yd = Y and the consumption and saving functions become, (b) (i) With direct taxation, Yd= Y – T. When T = 300, the consumption function becomes, A lumpsum tax shifts as consumption function down parallel to the original consumption function.
