From this data I will graph both the Consumption Function and the Savings Function and calculate the MPC and the MPS. The consumption function can be calculated using a simple formula: C = A + MD where C is the consumer spending, A is autonomous consumption (spending regardless of income levels), M is the marginal propensity to consume (the amount of additional income needed to spend on goods and services rather than saving it), and D is the amount of real disposable income required. *You can also browse our support articles here >. .

If the marginal propensity to consume = 0.75, then: A: the marginal propensity to save = 0.75.B: the marginal propensity to save = 1.33.C: the marginal propensity to save = 0.20.D: the marginal propensity to save = 0.25.E: since the marginal propensity to save and the marginal propensity to consume are unrelated, we cannot determine the marginal propensity to save from the information given. [11] It can be difficult to prioritize your health, but you don't have to do it alone. c. Due to the recession, planned investment spending decreases, What type of spending depends primarily on these factors: the interest rate, the expected future level of real GDP, and the current level of productive capacity. Generally, consumption equals autonomous consumption plus the product of marginal propensity to consume and disposable income. So when final product demand is elastic, an increase in wages will lead to a large change in the quantity of the final product demanded affecting employment greatly.
