The marginal propensity to consume has a value that is less than one, according to Keynes' theory, which is stated by the following formula:
Marginal Propensity to Consume(MPC) <1.
This is how MPC and consumption function are related to one another. Consumers spend their marginal propensity by consuming things that represent a small portion of the total payment raise.
This computation is crucial because MPC fluctuates depending on income level and is not a constant. Typically, as income rises, more of a person's wants and needs are met.
The fundamental tenet of the consumption model is that consumer consumption forecasts will be more precise than retailer-placed supplier demand forecasts.
