classical vs keynesian theory of income and employment

First, for taking the aggregate supply to be stable as noted above. What is meant by Propensity to consume (or Consumption function)? In the Keynesian system money in neutral in situations of full employment and liquidity trap (when the rate of interest becomes inelastic in a depression). (b) Keynesian Theory of Income and Employment. The critical evaluation of Keynesian economics reveals that there are the Keynesians who eulogise Keynes and there are the anti-Keynesians like Hazlitt who “could not find a single doctrine that was both true and original.”, On the other hand, Keynes’ greatest follower Dillard writes, “Keynes was an original thinker in the sense that he arrived at his ideas in his own way. For example, suppose that the economy is going through a downturn so the demand in the market has fallen. For instance, an unfavourable balance of trade leads to the flow of income abroad which results in the reduction of domestic income, investment and the volume of employment via the reverse operation of the multiplier. Keynes attacked not the logical consistency of the classical economic theory, but its empirical premises. Download the PDF Question Papers Free for off line practice and view the Solutions online. Output creates income. In other words, AD is the total expenditure which all sectors of economy are willing to make on purchase of goods and services. Policy Implications 10. Content Guidelines 2. The tools and assumptions on which the Keynesian economics is built are incapable of bringing the development of such economies. Hence there is neither general over-production nor unemployment. Thus consumption (C) is a function (f) of income. The core issue of macroeconomics is the determination of level of income, employment and output. According to Professor Schlesinger, the Keynesian theory of aggregate demand suffered from certain inherent defects which made his theory of employment unrealistic. Advocated government intervention to bring about equilibrium between AD and AS through monetary and fiscal measures and to ensure full employment and its continuity. As pointed out by Hicks, “The theory of the acceleration and the theory of multiplier are the two sides of the theory of the fluctuations, just as the theory of demand and the theory of supply are the two sides of the theory of value.”. Thus total consumption (C) comprises two components (i) Autonomous Consumption, influenced by income, and (ii) Induced Consumption (bY) influenced by income. But as pointed out by Professor Harris, “It is a matter of judgement whether the General Theory is simply classical economics further developed or embroidered, or whether Keynesian economics represents a genuine break.”. Since during short period supply is constant, it is because of deficiency in effective demand, which causes unemployment. The Keynesian theory is based on the assumption of a closed economy which excludes the impact of foreign trade on the level of employment and income. 4. Policy Implications 10. Most of the modern economists agree with the concept of Keynes. Introduction The Classical Model was prevailing with full popularity before the Great Depression of 1930. (f) Lastly, the Keynesian economics fails to provide solutions to a number of socio-economic problems facing the developed countries. He regarded the rate of interest as a purely monetary phenomenon. But it is not essential that the entrepreneurs must employ more workers if there is imperfect competition in order to reach equilibrium level of employment. He thus ‘smashed the last pillar of the bourgeois argument’ that unequal income led to increased saving and to capital formation for growth. This makes Keynes’s analysis unrealistic. The Great Depression led to break down of Classical theory.It was at that time that J.M. The influence of the rate of interest in determining the volume of investment is very uncertain. There is “money illusion” in the Keynesian speculative demand for money which means that the increased supply of money is absorbed only at a lower rate of interest. So aggregate demand should be raised in order to raise level of employment. Image Guidelines 5. Variation in rate of interest establishes equilibrium between saving and investment. Some numericals for further clarification are given below. Since it is measured by total expenditure of the community on goods and services, therefore, aggregate demand also means aggregate expenditure on final goods and services in the economy. To Klein, “The revolution was solely the development of a theory of effective demand,” and to Hansen, “Consumption function is an epoch making contribution to the tools of economic analysis.”. Effective demand results in output. The Keynesian theory is not applicable even to modern capitalist economies where there is monopolistic competition rather than perfect competition. Criticisms. (b) Keynesian theory of employment. Sufficient market exists for all the produced goods and services. It was J. M. Keynes who first analyzed the frequent problem of unemployment and fluctuating levels of real output or national income. Content Filtrations 6. The ideas he advanced were his own even though someone else may have expounded the same or similar ideas at an early date.”. Economists have criticised Keynes’s principle of effective demand for two reasons. But the Great Depression of 1930s, proved the theory wrong. Keynes discarded the policy of laissez-faire because he believed that enlightened self-interest did not always operate in the public interest and it was this policy which led to the Great Depression. Delhi - 110058. Keynesian model has been developed as a reaction against the classical model. Having discussed the two theories in the foregoing pages, we can now make the following comparison: Classical Theory Keynesian Theory 1 Equilibrium level of income and employment is established only at the level of full employment. Keynesian economics also recognizes that only a fraction of the household income will be … TOS 7. Keynes has been criticised for his over emphasis on expectations. On the contrary, "demand creates its own supply”. (ii)    "Demand creates its own supply" Unlike Classicals; Keynes believed that it is the demand that creates supply and not that supply creates demand. “Viewing Keynes’s theory as a whole, its revolutionary nature lies,” according to Prof. Dillard, “in the repudiation of any presumption in favour of laissez-faire.”. In the Keynesian theory, employment depends upon effective demand. Classical theory is the basis for Monetarism, which only concentrates on managing the money supply, through monetary policy.Keynesian economics suggests governments need to use fiscal policy, especially in a recession. The extent to which an economy moves naturally towards equilibrium without the interference of government, is the subject of intense debate in economics and has been so since its origins. He was a friend. The premise of full employment runs throughout the whole structure of this theory. In order to maximize their profit, firms employ factors of production to the point where margi… Keynes's income‐expenditure model. The premise of full employment runs throughout the whole structure of this theory. Policy of ‘Laissez Faire’ 4. The classical and the neoclassical economists almost neglected the problem of unemployment. https://www.zigya.com/share/RUNFTjEyMDUxMzk4. It implies that the national income and employment which correspond to the effective demand are equilibrium levels of national income and employment. ADVERTISEMENTS: The Keynesian Theory of Income, Output and Employment! (i) At zero or very low level of income, consumption expenditure is higher than income because minimum consumption is necessary for survival, and (ii) As income increases, consumption expenditure also increases but increase in consumption is less than the increase in income. Keynesian vs Classical Theory of Unemployment An approach to the Spanish labor market. They are the wealth effect, technological change, education, expectations, attitudes toward assets, etc. Thus Keynes’s neglect of the repercussions of foreign trade on the volume of employment is a serious defect in his theory. Plagiarism Prevention 4. This is the basic difference between Classical Theory and Keynesian Theory. Symbolically: C = f(Y).Consumption function (linear, i.e., straight line consumption function) is represented by the following equation.Thus total consumption (C) comprises two components (i) Autonomous Consumption  not influenced by income, and (ii) Induced Consumption (bY) influenced by income. According to Hazlitt, the volume of employment is not a function of effective demand rather it depends upon the inter-relationship between wage- rates, prices and the supply of money. This may have cumulative adverse effect on private investment, and thus lead the economy towards recession. Besides, every bit of Keynesian analysis has been criticised, such as aggregate demand, aggregate supply, the consumption function, the investment function, the monetary theory, etc. Keynes possessed great intuitive power and confidence for he wrote to George Bernard Shaw in 1935 before the publication of his General Theory, “You have to know that I believe myself to be writing a book on economic theory which will largely revolutionise nor, I suppose at once, but in the course of the next ten years—the way the world thinks about economic problem.” Undoubtedly, the Keynesian analysis has significantly influenced matters of policy in the capitalist economics of the world. The main points of contrast between the classical and Keynesian theories of income and employment are discussed in brief as under: (1) Unemployment: The classical economists explained unemployment using traditional partial equilibrium supply and demand analysis. Theoretically, a wage-cut policy increases unemployment instead of removing it. Though he said that the role of public investment was to supplement private investment and not to supplant it, yet public investment has tended to replace private investment to a large extent. Lastly, Keynes has also been criticised by Harrod for formulating his theory in “stock” terms and neglecting the “flow” variables. Keynes’s consumption function though regarded as an epoch-making contribution to the tools of economic analysis yet it is not free from defects. (c) Keynes advocated progressive taxation to control inflationary trends in the economy. There are jobless resources and therefore less than full employment symmetry prevails. The aggregate supply is regarded as stable during the short-run. To try to cure unemployment by inflation is to adjust the piano to the stool rather than the stool to the piano.” Therefore, inflation or deficit spending cannot be relied upon to cure unemployment. product, labour and money. Mind, level of household consumption depends directly on the level of income. He opines that “over-all demand is of course, to some extent, affected by relations on the supply side, Keynes’s treatment of demand was therefore over-simple in that it neglected the possibility that the relative prices prevailing in the different sectors determine, in part, the total amount of outlays.”, Professor Don Patinkin regards Keynes’ treatment of the aggregate supply function inadequate. This stems from his weakness to relate saving as an ex-post factor pertaining to the current period. Classical theory is the basis for Monetarism, which only concentrates on managing the money supply, through monetary policy. This is the basic difference between Classical Theory and Keynesian Theory. Keynes made no attempt to show the process of transition from one position of equilibrium to another, however. Keynesian Model 9. Assumptions 4. He was a benefactor of humanity. Keynes theory were widely accepted and provided the basic foundation for the modern theory of employment. Classical theory is the basis for Monetarism, which only concentrates on managing the money supply, through monetary policy. We study some of the major criticisms below: Keynes asserted that the, level of employment depended upon the level of aggregate demand which was in turn determined by the inactive consumption demand and active investment demand. Since Keynes assumes all these four quantities, viz., effective demand (ED), output (Q), income (Y) and employment (N) equal to each other, he regards employment as […] Thus aggregate demand is synonymous with aggregate expenditure in the economy. Criticisms. Lastly, his theory of investment failed to consider the effect of investment on technological progress. Thus wage-price flexibility is the built-in stabiliser to ensure full employment.The Great Depression of 1929–33. Fans of this theory may also enjoy the New Keynesian economic theory, which expands upon this classical approach. The pure, unadulterated capitalism of the classical ideology could not function because as Keynes wrote, “It is not intelligent, it is not beautiful, it is not just, it is not virtuous and it does not deliver the goods.”, Keynes reformed capitalism by advocating the necessity of state intervention in order to increase aggregate demand and employment and thus saved it from giving way to communism. The classical theory relates only to the special case of full employment. He proved that an economy could be in equilibrium even at less than full employment level. Keynes found that the classical economics provided no solution to the actually prevailing problem of wide-spread unemployment during the Great Depression of 1930s. He, therefore, favoured state intervention and stressed the importance of public investment to fill the gap created by the deficiency of private investment. According to Keynes "Aggregate supply is perfectly elastic with respect to prices till the full employment level of output is reached.").Fig. The demand for labors and other factor resources are determined by the demand for the products in the market. According to him, the classical theory is perfectly logical, but it is incapable of solving the … Keynesian economics is called the Keynesian revolution. Summary 6. (a) Classical Theory of Employment. Thus in the words of Joan Robinson, “The Keynesian revolution has destroyed the old soporific doctrines and we are left in the uncomfortable situation of having to think for ourselves.”. The classical theory assumed the prevalence of full employment. Prof. Ackley calls the Keynesian model as “too static.”. Thus the Keynesian theory is divorced from reality. “The essence of this convention,” according to Keynes, “lies in assuming that the existing state of affairs will continue indefinitely, except in so far as we have specific reasons to expect a change.” The reliance on the convention hypothesis makes Keynes’s concept of expectations superfluous and unrealistic. In short, consumption equation, Consumption (C) at a given level of income (Y) is equal to autonomous. The economy is a closed one devoid of any influence of the foreign trade (X-M) i.e., X-M is zero. Thus income or total output measures the aggregate supply of goods and services.Aggregate Supply = Output = IncomeA major portion of income is spent on consumption of goods and services and the balance is saved. For a real understanding of the working of macroeconomic variables like income, investment, consumption, employment, etc., the study of their micro-behaviour is essential. (b) Keynesian theory of employment. He accepted the classical theory, criticised and extended it and at the same time rejected parts of it. We know that money value of final output is distributed as rent, wages interest and profit among factors of production who help produce the output. Thus the aggregative nature of Keynesian economics detracts from its utility as a realistic study of economic problems. Privacy Policy 8. For instance, the principle of effective demand states that when the aggregate demand curve is over the aggregate supply curve, the entrepreneurs employ more labourers in expectation of earning larger profits till the point of effective demand is reached. Mind, determination of output and employment in Keynesian framework depends mainly on level of aggregate demand in short period. Keynes, on the other hand, integrated monetary theory and value theory. 2. He also brought interest theory into the domain of monetary theory. There is no cyclical unemployment in such economies. Keynes considered his theory as a “general theory.” But as is clear from the above points, it is not a general theory but a special theory which is applicable only under static conditions in a perfectly competitive closed economy. the interest rate will not always equalize savings and investment. Say's Law of Market. Emphasis on the Study of Allocation of Resources Only 3. Effective demand is derived from the actual household disposable incomes and not from the disposable income that could be gained at full employment, as the classical theories state. Salary and prices stay constant. Classical economics places little emphasis on the use of fiscal policy to manage aggregate demand. Keynes also did the same thing. (b) Keynes’s favoured public investment to overcome depression and to attain full employment. As rightly pointed out by Prof. Hansen, “The General Theory has helped to make us think of economics in dynamic rather than in static terms.”, Keynes’ most significant contribution lies in saving capitalism from the catastrophe it had fallen in the 1930’s. Individuals are price takers, … The Keynesian Theory is different from Classical theory in the following ways: Unemployment: Keynesian Theory accepts the fact that there is unemployment, the economy cannot function always on Full Employment Mode, it is just possible for a short period. CHAPTER 5: OUTPUT-EMPLOYMENT THEORIES (CLASSICAL AND KEYNESIAN) 5.1 Classical Theory (A) Introduction: Employment and output analysis at macro level has become an important part of economic theory only during and after the Second World War period. Keynes used his income‐expenditure model to argue that the economy's equilibrium level of output or real … But he was wrong because it is also interest elastic though at high interest rates. Further, Keynes neglected the relationship between capital stock and investment. Thus Keynes makes the saving-investment relationship very confusing. He put forth a general theory of employment applicable to every capitalist economy. The ‘Great Depression’ of 1929 to 1934, engulfing the entire world in widespread unemployment, low output and low national income, for about five years, upset the classical theorists. Their conviction in wage flexibility. His policy measures have been adopted by almost all the capitalist economies of the world. In the General theory of employment, interest, and money, Keynes disagreed with the Classical notion that: a market economy is self-regulating and always automatically moves to macroeconomic equilibrium at the full employment level of real GDP Saulnier points out that Keynes Notes on the Trade Cycle lack in factual proof. The Great Depression of the thirties demolished whatever faith was left of the self- regulating capitalist system. Hence equilibrium level of income occurs at level of full employment, i.e., there is always full employment equilibrium. Therefore, there is neither overproduction nor underproduction.Thus full employment is a normal situation and if at all there arises any unemployment, it is automatically corrected by market forces. Equilibrium level of income and employment is established at a point where AD = AS. These problems lie generally outside the scheme of the General Theory. This makes Keynes’ analysis unrealistic because all economies are open economies, and foreign trade has an important impact on their level of employment. Keynes’s treatment of the speculative demand for money is very narrow because he confined himself only to cash and bonds, and failed to consider other types of assets. He was a dunce. This belief is based on Say's Law of Market that states, "Supply creates its own demand.” which implies that supply (production) creates a matching demand for it with the result that whole of it is sold out. Keynes’ real contribution to the business cycle analysis lies in his explanation of turning points of the cycle and in the change of attitude as to what should and should not be done by the government to control the cycle. Introduction to Keynesian Theory 2. Moreover, Keynes ignored what Patinkin calls the “direct influence of real-balance effect on aggregate demand.” When the wealth of the people increases, it affects consumption and hence the demand for money. In the General theory of employment, interest, and money, Keynes disagreed with the Classical notion that: a market economy is self-regulating and always automatically moves to macroeconomic equilibrium at the full employment level of real GDP   Keynesians believe consumer demand is the primary driving force in an economy. According to Classicals "Aggregate supply is perfectly inelastic with respect to prices and it (aggregate supply) is always at full employment level of output." Variables 5. Keynesian variant of Classical theory emphasises that such disequilibrium may not be self-correcting, since the failure of prices to adjust may reflect permanent features of the real world, especially the asymmetric distribution of information among the bargaining parties.
