Unfortunately, not all of these models consistent - one model may predict that unemployment will fall if the central bank lowers the target interest rate while another may claim that such a change will not affect unemployment. The consumption function is given by C = 100 + 0.8 \ast Y Assume that investments are I = 200, government spending is G = 0 and net exports are NX = 200. Since they are not measured on either axis, we should note that a change in a non-income determinant of consumption will shift the entire consumption function not merely move you along a fixed consumption function.
