## Keynesian Theory of Income Determination

S is the saving incline. For example, in Table-1, when the income or aggregate supply is at Rs. Saving is a function of income, i. In other words, whatever the aggregate demand, more output of goods will be produced and supplied at the same price before full-employment of resources is reached. Y from the horizontal axis to vertical axis. In case the equilibrium level of national income is above the level of full employment, this means that the output has increased in money terms only. Once investment increases, employment and income increase.

Concept of Multiplier : The concept of multiplier can be understood by determining the relationship between change in national income ΔY and change in investment ΔI. Because the mpc is the fraction of a change in real national income that is consumed, it always takes on values between 0 and 1. Equilibrium is not Necessary Established at Full-Employment Level: The most important contention of J. Thus, in Keynesian theory of income determination, investment does not vary with change in income. Thus aaggregate demand is the total value of all planned expenditure of all buyers in the economy.

Keynesian theory of income determination can be explained by assuming two sectors in the economy, namely, households and business firms. There are two important constituents of aggregate output: 1. It is also termed as investment multiplier because change produced in national income is due to change in investment. Therefore, the propensity to consume is stable. The supply or output of final consumer goods and services in a year; and 2.

## The Keynesian Theory

Keynes argues that aggregate consumption expenditures are determined primarily by current real national income. The rate of interest is determined by the demand for money and the supply of money. Keeps the prices of goods and services, supply of factors of production, and production technique constant throughout the life cycle of organization. So long as their receipts are higher than the costs, they will increase employment as they can increase their profits by offering more and more employment. The output of capital goods which are also called producer goods because they help in producing further goods. Figure-5 provides a graphical representation of national income determination by using the saving-investment approach: In Figure-5, equilibrium point is at E where the investment and saving curve intersects each other.

Keynes laid more emphasis on the determinants of aggregate demand and to a greater extent ignored the determinants of aggregate supply. To under­stand the Keynesian viewpoint consider Fig. Aggregate demand involves concepts namely aggregate demand for consumer goods and aggregate demand for capital goods. . In Keynesian study the symmetry level of employment and earnings is ascertained at the point of equality between saving and investment. In fact, both income and employment go together. Products are paid for with products i.

He severely criticized that cuts in real wages help in promoting employment in the economy. Investment is assumed to be autonomous and thus independent of the income level. The equilibrium position between aggregate demand and aggregate supply can be below or above the level of full employment as is shown in the curve below. The, aggregate expenditure shows aggregate demand for goods and services. This analysis ex­plains determination of national income by relating income output to aggregate expenditure on goods and services. Effective demand is ascertained by two aspects, the aggregate supply function and the aggregate demand function. It is defined as total value of goods and services produced and supplied at a particular point of time.

## What is the Keynesian model of income determination?

Therein lies the importance of the concept of effective demand. As a result, the existence of full employment is not possible. The national income at equilibrium level is Rs. The marginal propensity to consume mpc , which multiplies Y, is the fraction of a change in real income that is currently consumed. Note that as the level of Y increases, so too does the level of aggregate consumption. The term 'aggregate' is used to describe any quantity that is a grand total for the whole economy.

## The Determination of National Income: Keynes's Basic Two Sector Model

Since Keynes believes the aggregate supply function to be stable, he contemplates his entire concentration upon the aggregate demand function to fight gloominess and redundancy. National income is the same thing as national product as both represents the value of output of final goods and services produced. The book revolutionized macro economic thought. It is the total demand for goods and services in the economy Y in a specific time period. Increase in personal taxes reduces personal disposable in­come and therefore consumption expenditure.

This mannerism of the consumption function widens the gap amidst income and consumption which ordinarily cannot fill up due to the lack of required investment. Determination of National Income in Two-Sector Economy : The determination of level of national income in the two-sector economy is based on an assumption that two-sector economy is an economy where there is no intervention of the government and foreign trade. You will get one-to-one personalized attention through our online tutoring which will make learning fun and easy. In any particular year, there will be a given level of investment demand which, as seen above, is determined by marginal efficiency of capital and a given rate of interest. According to Keynes the symmetry level of employment will be one of under employment symmetry for the reason that when earnings enhances consumption also enhances but by less than the augment in earnings.
