Graphical representation of the consumption function, where a is autonomous consumption (affected by interest rates, consumer expectations, etc.), b is the marginal propensity to consume and Yd is disposable income. In economics, the consumption function describes a relationship between consumption and disposable income.
Average propensity to consume (APC) (as well as the marginal propensity to consume) is a concept developed by John Maynard Keynes to analyze the consumption function, which is a formula where total consumption expenditures (C) of a household consist of autonomous consumption (C a) and income (Y) (or disposable income (Y d)) multiplied by marginal propensity to consume (c 1 or MPC).
Consumption is the act of using resources to satisfy current needs and wants. [1] It is seen in contrast to investing, which is spending for acquisition of future income. [2] Consumption is a major concept in economics and is also studied in many other social sciences. Different schools of economists define consumption differently.
This has led to the absolute income hypothesis falling out of favor as the consumption model of choice for economists. [3] Keynes' consumption function has come to be known as 'absolute income hypothesis' or 'absolute income theory'. His statement of the relationship between income and consumption was based on psychological law.
In economics, the marginal propensity to consume (MPC) is a metric that quantifies induced consumption, the concept that the increase in personal consumer spending (consumption) occurs with an increase in disposable income (income after taxes and transfers). The proportion of disposable income which individuals spend on consumption is known as ...
In Keynesian macroeconomics, the Fundamental Psychological Law underlying the consumption function states that marginal propensity to consume (MPC) and marginal propensity to save (MPS) are greater than zero(0) but less than one(1) MPC+MPS = 1 e.g. Whenever national income rises by $1 part of this will be consumed and part of this will be saved

Isoelastic utility for different values of . When > the curve approaches the horizontal axis asymptotically from below with no lower bound.. In economics, the isoelastic function for utility, also known as the isoelastic utility function, or power utility function, is used to express utility in terms of consumption or some other economic variable that a decision-maker is concerned with.
