The consumption function also includes a planned expense. The real interest rate determines the level of investment, even if you do not have to borrow the money to buy the equipment. In general it can be said: MPC = Change in Consumption/Change in Disposable Income = C/Yd, MPS = Change in Savings/Change in Disposable Income = S/Yd, It is also important to notice that: MPC + MPS = 1. Households increase savings during recessions, which causes consumption to fall, aggregate expenditures to fall, and may possibly lead to or make worse a recession.

At income levels to the right of point E (like Io), savings is positive because consumption is below income, and at income levels to the left of point E (like I'), savings is negative because consumption is above income. The study uses the non-linear autoregressive distributed lag (NARDL) model for individual and panel time series.
