keynes theory of employment short notes

But what are the factors on which business expectations about opportunities of making profits depend. It gave way to an entirely new approach where employment, inflation and the market economy are concerned. During the period 1929-33, there occurred great depression in the capitalist countries which caused huge unemploy­ment of labour and other resources in those countries and as a result level of national income fell down. Investment demand depends on the rate of interest and marginal efficiency of capital. The sticky or rigid money wages above the equilibrium level cause unemployment of labour. They thought that when there is unemployment in the economy, then, given the free and perfect competition in the economy, certain economic forces auto­matically operate in such a way that the condition of full-employment is restored. ( Log Out /  Due to this depression, unemployment spread in all independent capitalist economies. Keynes attributed this to money illusion on the part of the workers. Keynes in his volume General Theory of Employment, Interest and Money had not only criticized the Classical Theory of Employment, but had also analyzed those factors that affect the employment and production level of an economy.Most of the modern economists agree with the concept of Keynes. Like the aggregate supply price, aggregate demand price also varies at different levels of employment. As regards investment demand, according to Keynes, it is determined by rate of interest on the one hand and marginal efficiency of capital on the other. It will be seen from Fig. Knight criticised Keynes’s theory in view of the facts which are directly contrary to what the theory calls for. As said above, aggregate supply curve shows the revenue or receipts which must be received by the entrepreneurs so as to provide employment to different numbers of workers, whereas aggregate demand curve shows proceeds or receipts which entrepreneurs actually do expect to receive at different levels of employment and production. 1. The workers are rendered unemployed be­cause at a given wage rate supply of labour exceeds demand for labour. It is worth noting that it is due to the frequent changes in business expectations that investment demand is volatile. general theory of employment interest and money de keynes john maynard. Since beyond this point aggregate supply price will exceed aggregate demand price, the cost of production incurred on employing a certain number of people will not be covered. Unemployment is due to the deficiency of effective demand and the basic remedy to remove this unemployment is to raise the level of the effective demand. Given that the perfect competition prevails in the economy, then so long as opportunities to earn profits or make money exist, the entrepreneurs will increase the level of employment. (ii) His "day" (p. 47) is not the same as mine. As a result, output and income of the community also fall. When prospects for profit making in future are bright, there will be more investment. TOS 7. These aggregate demand and the aggregate supply curves determine the level of employment in the economy. B. The view of Keynes is that when investment demand falls short of this gap between full-employment income and consumption recession occurs resulting in the emergence of involuntary unemployment. Theory of emplyment 1. sort when supplying their labor services. Keynes’ theory of employment is a demand-deficient theory. Prohibited Content 3. It is however worth noting that Keynes thought in conditions of depression/recession when huge unemployment of labour prevailed in the economy, with the increase in labour employment to produce more, wage rate will remain constant. in conditions of full employment, are expected to yield less than nothing; and the resulting collapse of new investment then leads to a state of unemployment in which the investments, which would have yielded 2 per cent. All those who are willing to get jobs at the real wage rate W0/P0 are in fact demanded and employed. In an advanced capitalist economy, the level of employment depends upon the level of aggregate effective demand, the greater the level of effective demand, the greater the amount of employment in the economy. He wrote several books. We will now discuss below these concepts of aggregate supply and aggregate demand functions and will show how they determine the equilibrium level of employment. This is because, given the amount of capital, technology and labour efficiency, increase in income and output can be obtained by employment of more labour. For my clock struck midnight with income in the hands of its final The theory of employment developed by classical economists is called classical theory of employment. Privacy Policy 8. But in the analysis of the determination of employment in the advanced capitalist economies in the short run aggregate supply curve can be assumed to be given and constant. As these changes, or as production technol­ogy is improved, AS curve will also change. Create a free website or blog at WordPress.com. In Fig. In this introduction to the theory of employment, we confine ourselves to the consumption demand and investment demand. According to Keynes, aggregate demand price and aggregate supply price will be equal at full- employment only if investment demand is sufficient to cover the gap between the aggregate supply price corresponding to full-employment level and the consumption expenditure out of income at the full-employment level. While rate of interest is more or less sticky, it is changes in marginal efficiency of capital (i. e., expected rate of return) that cause frequent changes in inducement to invest. Image Guidelines 5. Theory Of Employment. ( Log Out /  The General Theory of Employment, Interest and Money, published in 1936, was Keynes's crowning achievement, and it took the world by storm. We have critically examined the classical theory of employment and the Say’s law of markets on which the classical theory is based. In panel (a) of Figure 4.3 the level of labour employment N0 shows the number of jobs when the economy is producing Y0 level of national output in panel (b) corresponding to the equilibrium between aggregate supply AS and aggregate demand AD0 at price level P0, with a fixed money wage and the level of GNP equal to Y0. Therefore, aggregate supply price will rise as more labour is employed to produce goods and services. Therefore, people’s belief in the classical economic thought regarding the tendency to full-employment was shaken. Most of the modern economists agree with the concept of Keynes. Assuming that marginal cost of production rises with the increase in employment of labour, upward rising aggre­gate supply curve AS with increasing slope as more labour is employed is shown in Fig. The General Theory of Employment, Interest and Money By John Maynard Keynes GENERAL INTRODUCTION Capitalism is not for the faint of heart. This means that labour market does not clear in the short run. We have seen that the magni­tude of employment in the economy is determined by the equilibrium between aggregate demand and aggregate supply. 4. 6. Once all the men willing to get employment are employed, then we have a state of full employment. Thus, equilibrium at E0 or at level of employment N0 represents full-employment equilibrium. Under-employment Equilibrium: The Problem of Demand Deficiency: It is not necessary that the equilibrium level of employment is always at full employment. It is important to note that Keynesian theory of income and employment is a short run theory because Keynes assumes that the amount of capital, the size of population and labour force, technol­ogy, efficiency of labourers, etc., does not change. Book VI: SHORT NOTES SUGGESTED BY THE GENERAL THEORY. Content Filtrations 6. (ii) Keynesian theory of employment is a short-run theory which attempts to analyse the short-run phenomenon of unemployment. There are two reasons for existence of money illusion: (i) First reason for the existence of money illusion is that workers of a firm or industry think that though rise in prices reduce their real wages, but that this rise in prices equally affect workers in other industries so that their relative wages as compared to those employed in other industries remain the same. In most of the free market economies such as those of USA and Great Britain, wages are fixed by the firms through contracts made with the workers for a year or two. But, when output and employment are increased, more cost of production is incurred. Keynes also invented new tools and concepts of economic analysis in terms of which he propounded his theory of income and employment. 3. In other words, efforts should be made to increase aggregate sup­ply when full-employment level has already been achieved and the economy is in the grip of inflation. This is for the simple reason that in times of depression the main problem of advanced capitalist economies is how to employ idle manpower and capital resources to increase production by raising demand and not that how the productive capacity be raised by augmenting the stock of capital or by improving the techniques of production. There is little possibility of changing money wages fixed through contracts when the situation of either labour surplus or shortage emerges. The Keynesian Theory of Employment is a produce of the world wide depression of 1931-36. Keynes asserted that the economy would remain stuck at point K with less than full-employment level of output Y1 and lower price level P1 Now, a glance at panel (a) of Fig. Marginal efficiency of capital means expected rate of profit by the entrepreneurs from the investment they propose to undertake. We have explained above the practical difficulties pointed out by Keynes and his followers which are faced by firms in reducing wages and which therefore explain money-wage rigidity or stickiness. The higher the level of effective demand, the greater is the volume of employment, and vice versa. 4.3 that new aggregate demand curve AD1 and the fixed aggregate supply curve AS intersect at point K determining new equilibrium lower price P1 and smaller real GNP equal to Y1. 4.2 that in the situation of equilibrium at the employment level ON2 the N2NF persons remain unemployed. Therefore, in his theory of income and employ­ment he assumes that prices remain constant. Keynes is considered to be the greatest economist of the 20 th century. According to Keynes, rate of interest is determined by supply of money and the state of liquidity preference. That is why Keynes assumed the AS curve to be constant and paid greater attention to the factors determining aggregate demand. It is in this way that Keynes explained that with money wage rate remaining fixed at the level W0 and with flexible prices, the fall in aggre­gate demand results in persistent involuntary unemployment. This book is an essay in the explanation of The General Theory of Employment, Interest and Money (Keynes, C.W. We explain below the outline of the Keynes’s theory of employment. It is important to note that N2NF persons are involuntarily unemployed, they are willing to work at the existing wage rates but are unable to find jobs. The curve of aggregate supply price AS starts from the point of origin and slopes upward to the right. Article shared by. The labour market must be in equilibrium at point E0 or real image rate W0/P0 at which N0 workers are demanded and employed. His theory is thus known as demand-oriented approach. This unemployment will be removed and full-employment equilibrium will be reached if through increase in investment demand or increase in consumption, or increase in both, aggregate demand curve shifts upward so that it intersects the aggregate supply curve at point R as depicted in Fig. It is important to note that Keynesians do not believe that money wage rate is completely fixed or sticky. Before publishing your articles on this site, please read the following pages: 1. CLASSICAL THEORY OF EMPLOYMENT For this theory, French economist J. The aggregate supply curve depends ultimately on the physical and technical conditions of production (that is, capital stock, the state of technology and the nature of production function). When the state of full employment is reached further increases in aggregate demand or expenditure will be unable to increase employment further since output of goods and services cannot be increased further as no more labour is available for production after full-employment level is reached. 4.3 suppose due to fall in marginal efficiency of capital there is reduction in investment demand which along with its multiplier effect causes a leftward shift in the aggregate demand curve AD. Short notes suggested by the general theory. Thus we can construct a schedule or curve of aggregate supply showing aggregate supply price at different levels of employment. Thus the sticky or rigid money wages lead to the existence of involun­tary unemployment. According to him, when inducement to invest in capitalist countries declines due to the fall in marginal efficiency of capital (i.e., expected rate of profit), aggregate demand falls so that equilibrium is established at less than full-employment level. Aggregate demand in a simple Keynesian model consists of consumption demand and in­vestment demand. In such a situation, it becomes necessary to cause a rightward shift in the aggregate supply curve by making addition to the stock of capital and effecting improvements in production technology. Thus equilibrium at E represents under-employment equilibrium (or, in other words, less than full-employment equilibrium). Investment demand is thus highly volatile and causes recession or depression when it falls, and boom and prosper­ity when it increases significantly. Change ). Summary of Keynes’s Theory of Employment: After explaining Keynes’s theory of employment at some length, we are now in a position to describe it in a summary form bringing out relationship between various elements or factors that go to determine the equilibrium level of employment. There's so much more to read. According to Keynes, the economy could be thought of as being divided into consumer, investment (or business), government, and foreign sectors. As a result of unemployment, low in­come and production created by depression, people had to undergo a good deal of sufferings. 7. On all other points, aggregate demand price is either more or less than aggregate supply price. In the short run, he assumed that the factors of production, such as capital goods, supply of labor, technology, and efficiency of labor, remain unchanged while determining the level of employment. We have said that the aggregate supply is determined by the physical and technical conditions prevailing in the economy, that is, the quantity and quality of labour, stock of capital and raw materi­als available in the economy and the state of technology. That is why in Keynesian theory; the amount of employment depends upon the level of national income and production. short notes suggested by the general theory. In other words, effective demand is that aggregate demand price which becomes’effective1 because it is equal to aggregate supply price and thus represents a position of short-run equilibrium. Keynesian economics developed during and after the Great Depression from the ideas presented by Keynes in his 1936 book, The General Theory of Employment, Interest and Money. It is obvious that if the cost of production incurred by the entrepreneur in employing a certain number of labourers is not covered, they will reduce the amount of employment offered. Effective Demand and Determination of Employment: We are now in a position to explain more clearly what effective demand means and how it is important for determination of employment and output in the economy. Hazlitt also discusses this point without giving credit to Knight. Theory of Effective Demand: According to Keynes, the level of employment in the short run depends on aggregate effective demand for goods in the country. Mill, Marshall, Pigou etc. It is important to remember that, according to Keynes, this unemployment is due to deficiency of aggregate demand. Classical economists such as, J.S. Consumption demand depends on disposable income on the one hand and propensity to consume on the other. Aggregate supply of an economy depends on physical and technical conditions of produc­tion. Therefore, aggregate supply curve assumes a vertical shape after full-employment is reached. We summaries below the various determinants of employment and income (output) in a tabular form. Consumption demand depends on propensity to consume on the one hand and disposable income on the other. According to Keynes, while rate of interest is more or less sticky it is frequent changes in profit expectations of the entrepreneurs, that is, changes in marginal efficiency of capital that cause a great deal of fluctuations in investment by entrepreneurs. This view of them was based upon their belief in Say’s Law of Markets. Keynes’ argument is based on the idea that the level of employment is not determined by the price of labour, but by the spending of money. Propensity to consume of a community does not change much in the short run. Interest and Money” in which he challenged the validity of the classical theory of employment: Not only did he criticise the classical theory of full- employment and proved it wrong but also presented a new theory of income and employment which is generally believed to be correct and valid by modern economists. The Keynesian Theory of Employment is a product of the world-wide depression of 1931-36. It will be seen from panel (a) of Fig. Here we will explain only the outline of the Keynesian theory of income and employment. There is an aggregate demand function for an economy which shows aggregate demand price at varying levels of employment. Since the consumption demand increases with the increase in labour employment, aggregate demand curve also slopes upward to the right. Involuntary Unemployment: Keynes’s Money-Wage Rigidity Model: According to Keynes, due to money wage rigidity, that is, downward inflexibility of money wages results in involuntary unemployment of labour. Keynes’s aggregate supply function (curve) shows the relationship between the number of workers employed and the receipts which all firms in the economy must get if it is just worth employing those prices, remaining constant. Level of output or income of a country depends on the level of employment. However, it does not necessarily mean that trade unions remain silent spectators if they feel that changes in Government policy ad­versely affect their economic interests. Chapter 19: Changes in Money-Wages. Therefore, in the Keynesian short run, the higher the level of national income, the greater the amount of employment, and lower the level of national income, the lower the amount of employment. Through collective bargaining by trade unions with the employers wage scales are fixed for 3 to 4 years by contract. This aggregate supply curve (function) depicts rising aggregate supply price at various levels of labour employment. These new tools and concepts are propensity to consume, multiplier, marginal effi­ciency of capital and liquidity preference. It was only later, in The General Theory of Employment, Interest and Money, that Keynes provided an economic basis for government jobs programs as a solution to high unemployment.The General Theory, as it has come to be called, is one of the most influential economics books in history, yet…. in conditions of full … When at a level of employment aggregate demand price becomes equal to aggregate supply price, then after this it will be no more profitable to employ workers.
