The hypothetical consumption functions in the graphs are similar to actual short-run consumption functions; the empirical evidence suggests that distinct short-run and long-run consumption functions exist.
Now consider statement 2, which, in effect, says that people base their consumption on their permanent income and largely ignore deviations from that permanent income if they expect the deviations to be only temporary.
This point is very important, because the consumption function normally used in textbooks maintains that current income constrains current consumption, but the permanent-income hypothesis maintains that wealth is the true constraint on current consumption.

 Intermediate Macroeconomics - Consumption
In the Keynesian consumption function current disposable income is the only determinant of consumption, as shown in equation (1).
The change in consumption from one year to the next divided by the change in income is the marginal propensity to consume.
Consumption reported in the national GDP accounts and used in empirical studies does not correspond to the theoretical meaning of consumption.

 The Consumption Function   (Site not responding. Last check: 2007-10-26)
A key tool in building up economists' standard model of the business cycle is the so-called consumption function: an algebraic relationship between national income and consumption spending that tells us what, for each possible level of national income, the level of consumption spending will be.
We build up the consumption function from two facts: (1) that there is a baseline level of consumption spending that would continue even if incomes were zero, and (2) that for each $1 increase in total incomes, consumption spending increases by a smaller amount--say $c'.
The parameter c' of the consumption function is called the marginal propensity to consume.

The consumption function can be described by a simple linear equation where aggregate consumption = autonomous consumption + the marginal propensity to consume X income.
And at the point where the consumption function crosses the 45° line, consumption equals income and savings is zero, we call the assumption that households can only consume or save their income.

That intertemporal aspect is suppressed in the Keynesian consumption function as evidenced, for example, by the fact that it omits the interest rate entirely.
To understand the effects of changes in income on consumption, we therefore need to know whether a change in income is temporary or permanent, since a $1,000 temporary increase in income leads to a small increase in consumption, whereas a $1,000 permanent increase in income leads to a large increase in consumption.
Recent work on consumption has added rational expectations into the story, which really means assuming that people are very sophisticated in their guesses about what their income is going to do.

The dependence of consumption on current income is described in the Keynesian consumption function while the dependence of consumption on lifetime income is described in the life cycle hypothesis and the permanent income hypothesis.
The interest rate influences consumption via saving because of the intertemporal substitution from one period to a future period: Income that is not used for consumption purposes can be saved and consumed one period later, earning an interest payment and hence allowing for more consumption in the future.
This increase in the absolute amount available for consumption, as reflected in the interest rate, has then to be compared with the individualĀ“s rate of time preference (the latter expressing her patience with respect to later consumption, or, more generally, to delayed utility derived from consumption).

The consumption function tells you how a household plans to spend their income, and the savings function, correspondingly, tells you what is left over to put into a savings account.

and that, therefore, capacity constraints, as represented by the production function, for example, were much more important for explaining the level of economic activity than any of the elements of aggregate demand.
and, like the consumption functions for the market economies, were supposed to model consumers' behavior.
If, for example, aggregate consumption were constrained by the supply of consumer goods rather than by demand, then empirical estimates obtained by regressing the observed consumption expenditures on the observed disposable income would not properly represent

Consumption Utility - it is a criterion (or index) used to evaluate the effectiveness of customers consumption.
A low value of consumption utility, say 0.15, indicates that a customer is not satisfied with the consumption of a certain commodity; while high value, say 0.96, indicates that the customer is very satisfied.
Consumption utility function - The behavioral characteristics of human beings can be represented by the concept of consumption utility, and consumption utility function is the mathematical description of this concept.

In fact, the slope of the consumption function is the marginal propensity to consume (defined as the change in consumption associated with a change in disposable income, and approximately equal to 0.8 for the period from 1970-94).
Since we've already seen through the consumption function that consumption is linked to disposable income, and disposable income equals real GDP minus net taxes, it should be clear that consumption will be related to real GDP.
The import function shows the relationship between imports and real GDP (reflecting the underlying influence of real GDP in increasing imports), and the slope of that function (presently about 0.15, up from only 0.07 in 1970) is the marginal propensity to import.

The reason for price stickiness may be non-economic (people are reluctant to accept lower paying jobs even when unemployed) or economic (union wage contracts may prevent firms from cutting wages and thereby reducing prices, or firms may be reluctant to reduce wages because it reduces their workers' incentive to make a good effort).

If we had considered income taxes, which are a function of income, then the model would become more complicated because changes in income tax rates would not only shift the aggregate expenditure curve up and down but also change the slope of the curve.

The current level of consumption is a straightforward function, driven by the current level of income.
A long-run consumption function can be drawn, assuming that there is a growth trend.
If this is true, previous peak income would have been that of last year and thus would give a consumption function that looks like it depends on current income.

The Keynesian Theory of consumption is that current real disposable income is the most important determinant of consumption in the short run.
This is the change in consumption divided by the change in income.

Abstract: Following a brief description of demand function in econometrics, the fuzzy consumption function theory is introduced that characterizes the dynamically behaviors of market demand and fluctuation.
The fuzzy demand functions discussed here are developed based on the fuzzy consumption utility function theory developed by Zaptron scientists.
Mathematically, the fuzzy demand function is a more accurate measure on the consumption demand, compared against a traditional (non-fuzzy) demand function.
