National Income and Consumption and Saving Functions
Although national income accounting provides estimates of the nation's output, we shall concentrate on the relationship between consumption and income, called With no government and foreign trade sectors, income equals, by definition. nationa income, appear to be the result of huge accumulation of inventories ( which the economists treat as investment) and increase in personal consumption expenditure. The forecast for is that the economy will remain on an even keel provided personal consump- tion does .. ings in relation to domestic invest- . The relationship between consumption and income is shown in Table , national income is measured on X-axis and consumption expenditure on the.
Consumption Expenditure: Relationship and Important Observations
For example, if income increases by Rs crores and, as a result, consumption increases by Rs crores, the MPC is Rs. In postulating his consumption function, J. Keynes assumed that consumption increases as income increases, but by a smaller amount.
Thus implies that b, the MPC, must lie between 0 and 1. The parameter a is the portion of consumption which does not vary with income, i.
Short-run studies of the consumption function show that a is positive. Other points on the consumption function can be obtained in the same way. Once the intercept and slope are specified, a straight line is completely determined.
The Relationship Between Income & Expenditure
If a changes, the consumption function will shift so that the new function is parallel to the old. If b changes, the function will change its slope. It may become flatter or steeper.
- National Income and Consumption and Saving Functions
Since the decision on how much income to consume implies a decision on how much to save, a saving function may be derived with the aid of the consumption function. With no government and foreign trade sectors, income equals, by definition, consumption plus, saving, S: The parameter 1 — b, referred to as the marginal propensity to save or MPS, is the slope of the saving function.
Since income equals consumption plus saving, saving is the difference between income and consumption. Therefore, to find saving at each level of income, consumption is subtracted from income.
Consider income Y0 in Fig. At income Y0, consumption equals C0; consequently, saving equal S0, obtained by subtracting C0 from Y0. The result is an increase in the consumption of major purchases and non-essential goods. The increase in consumer expenditures is not a direct relationship to income. For every extra dollar earned, there may be a fraction spent on disposable income.
Low-income areas may actually see more in expenditures than in actual income at different times.

The difference between income and consumption is how much is spent and left over as savings at the end of the month. There are many factors that determine why consumers choose to spend more on goods not required for day-to-day living expenses. These include stock market trends, tax laws, and even consumer optimism. Economic experts look at historical data to predict future trends based on new market conditions.Consumption function basics - Macroeconomics - Khan Academy
The Effect of Consumer Confidence Consumers won't spend money unless they are confident in their personal economic situation and strength. This means consumers feel good about having and keeping a job with the potential of promotion.
Pay increases, stock portfolio rises and tax cuts can put more money in each person's pocket. As these conditions merge, consumer confidence increases. Consumer confidence is the trust a buyer has that he can afford a purchase either today or in the near future.
For example, consumer confidence is shown by homebuyer trends. This is a major purchase that takes decades to pay off.
A buyer must feel good about the economy, as well as feeling secure about his personal financial situation to take on such a major purchase. Establishing Business Inventory Practices Another factor that affects consumer confidence in inventory.
