John Maynard Keynes, one of the most influential economists of the 20th century, proposed the concept of the "psychological law of consumption" in his book "The General Theory of Employment, Interest, and Money." According to Keynes, this law states that the level of consumption in an economy is determined by the level of disposable income available to households.
In other words, the psychological law of consumption suggests that people are more likely to spend money when they have more of it, and less likely to spend when they have less. This idea is based on the concept of marginal propensity to consume (MPC), which refers to the percentage of an increase in income that is spent on consumption. According to Keynes, the MPC tends to be higher at lower levels of income, meaning that people are more likely to spend a larger portion of their income when they have less of it. As income increases, the MPC tends to decline, meaning that people are less likely to spend a larger portion of their income as their income increases.
The psychological law of consumption has important implications for macroeconomic policy. For example, if the government wants to stimulate economic growth, it can increase aggregate demand by increasing disposable income through measures such as tax cuts or increased government spending. This should lead to an increase in consumption, which in turn should stimulate economic growth.
The psychological law of consumption is not without its criticisms, however. Some economists argue that it does not adequately account for other factors that may influence consumption, such as consumer confidence, credit availability, and changes in the price of goods and services. Despite these criticisms, the psychological law of consumption remains a fundamental concept in macroeconomics and continues to shape policy decisions around the world.

This means that any unusual or extraordinary circumstances such as inflation, war, revolution, etc. You may also like this:. Explains the declining phenomena of MPC When consumption level remains unchanged even with an increment in the income level, the marginal efficiency of capital may decline. Unique Nature of Income Propagation: The fact that the entire increased income is not spent on consumption explains the multiplier theory. This can be avoided if the level of spending is equal to the level of income rise.
The more income in a period one has, the more is likely to be his consumption expenditure in that period. Therefore, to achieve and maintain equilibrium at full-employment level of income, increasing proportion of national income is needed to be invested. Thus, Keynes argues that average propensity to consume APC falls as income increases. It is assumed that behavior of the people concerning spending remains constant. Thus, the proportionate increase in the consumption is less than the proportionate increase in the income. Hi friends welcome to my website khanstudy. Propositions of Keynes Psychological Law of Consumption Let us now the main propositions of the psychological law of consumption, these are explained below — a When income increases, consumption expenditure also increases but by a smaller amount.
Before the economy reaches the full employment level, the downturn starts because people fail to spend the fu increment of their income on consumption. The reason is that as income increases, our wants are satisfied side by side, so that the need to spend more on consumer goods diminishes. Since investment opportunities are fluctuate with the changing rate of interest, the stable consumption function tends to lower the marginal efficiency of capital and investment in the short run. On the basis of this increasing proportion of saving with the increase in income and, consequently, the emergence of the problem of demand deficiency, some Keynesian economists based the theory of secular stagnation on the declining propensity to consume. Explanation of the business cycle MPC being less than unity enables us to understand the fluctuations that occur in the business cycle. This follows from the above proposition because when the whole of increased income is not spent on consumption, the remaining is saved. Whatever is not consumed out of disposable income is by definition called saving S ".
At point B, consumption equals disposable income and there is zero saving. It implies a decline in the marginal efficiency of capital. It is true that as a rule and on an average, as income increases, consumption will increase, but not by as much as increase in income. It is the inadequacy of investment which results in unemployment and logically, the remedy to overcome unemployment is increase in investment. In order to remove the widening gap, investment should made in the economy, assuming the consumption function is stable in the short run.

Consumption will only depend upon income. Assumption of Keynes Psychological Law of Consumption The Keynes law is based on the following assumption — i This law is based on the assumption that the psychological and institutional complex influencing consumption expenditure remain constant. Invariability of Psychological and Institutional Factors The institutional and psychological factors of people remain constant that leads to the stability of propensity to consume. Xn उपरोक्त फलन व्यक्ति की पसंद को दर्शाता है जो सामान्यतः प्रत्येक व्यक्ति के लिए अलग-अलग होत. The third assumption is that of a capitalistic laissez fake economy.
OMTEX CLASSES: State and explain Keynesian 'Psychological Law of Consumption'
This proposition is followed from the first proposition because when the whole of increased income is not spent on consumption, the remaining is saved. In such a situation, war, revolution, hyperinflation, etc. In other words, the rate of increase of consumption is lesser than the rate of increase in income. So when consumption does not increase by the full increment of income and consequently there is general overproduction and mass unemployment, the necessity of state intervention arises in the economy to avert general overproduction and unemployment through public policy. Consumption will only depend upon income. Rather it exceeds demand and leads to general overproduction and glut of commodities in the market. This law is called the Psychological Law of Consumption or the Fundamental Law of Consumption.
This shows that additional income earned is divided into consumption expenditure and saving. The psychological law of consumption shows the relationship between income and consumption pattern that exists among the household sectors in an economy. Thus, when aggregate income increases, aggregate consumption also increases, but by a somewhat smaller amount. The fraction of income spent on consumption by the rich families is lower than that of the poor families. Hence, increased income is divided into consumption and saving.
State and explain J.M. Keynes's ‘psychological law of consumption’.
It assumes a Constant Psychological and Institutional Complex : This law is based on the assumption that the psychological and institutional complexes influencing consumption expenditure remain constant. Thus supply fails to create its own demand. In the short run, they do not change and consumption depends on income alone. It means, this law only operates in a developed capitalistic economy where there is not any kind of government interference. This law boils down to this that the position and the shape of the consumption function curve depend entirely on income.
So, less is spent on consumption after a subsequent level of increment in their income. C,K,CY, and increased saving A CAC, than before. Hence, the increased income of Rs 100 crores in each stage is divided into some ratio between consumption and saving. This implies low demand which leads to decline in investment. The consumption expenditure is, however, increasing with increase in income, i. Before that economy reaches the full-employment income level Y,, the downturn will start because the gap between 45° line and C curve continues to widen. He propounded a law which is known as Psychological Law of Consumption.
