If consumption is defined as C = 2,000 + 0.8Y,then the value of the marginal propensity to save is 0.8.

Question

The marginal propensity to save (MPS) is the fraction of any change in income that is saved. It can be calculated as MPS = 1 - MPC (marginal propensity to consume). In this case, the consumption function is C = 2,000 + 0.8Y, which implies an MPC of 0.8 (the slope of the consumption function). Therefore, the MPS would be 0.2 (1 - 0.8), not 0.8.
