According to him, the trade cycle consists primarily of fluctuations in the rate of investment. The rate of interest goes up due to a rise in the liquidity preference of the people. Keynes’ theory of the trade cycle has been regarded as quite convincing since it explains exactly the cumulative processes, both in the upswing as well as in the downswing. Keynes provided the concept of equilibrium level of income for the short period. This site uses Akismet to reduce spam. Your email address will not be published. Half the Explanation: A complete theory of the trade cycle must explain not only the turning points of the trade cycle but also the periodicity of the business cycle. We can explain these points a little more elaborately. It has been noticed that all private-enterprise economies continue to grow while they suffer from cyclical fluctuations in economic activity. The essential of Keynes discussion of the trade cycle can be summed up as follows: 1. The boom conditions themselves contain the very seeds of their own destruction. Thirdly, his theory does not throw light on the periodicity aspect of the trade cycle. Likewise during boom conditions, the rate of interest ought to be lower because of the weak liquidity preference among the people instead it is high. As a result, the theory supports the expansionary fiscal policy. Investment is carried on up to the point where the marginal efficiency of capital (the profitability of capital) is equal to the rate of interest (i.e., the cost of borrowing capital). Keynes positioned his argument in contrast to this idea, stating that markets are imperfect and will not always self correct. Prof. Keynes's biographer Robert Skidelsky writes that the post-Keynesian school has remained closest to the spirit of Keynes's work in following his monetary theory and rejecting the neutrality of money. Let us start at the bottom of a depression. Half the Explanation 2. Keynes maintained that trade cycles are essentially caused by variations in the rate of investment due to the fluctuations in the marginal efficiency of capital. 2. Investment depends upon two factors: (a) marginal efficiency of capital, and (b) the rate of interest. Half the Explanation: A complete theory of the trade cycle must explain not only the turning points of the trade cycle but also the periodicity of the business cycle. Keynes argues that the rate of interest will depend upon the liquidity preference of the people in the country and the quantity of money available. But he explains those factors which brings changes in income, output and employment. While the prices of finished goods are declining, their costs of production continuously rise because factors of production are becoming scarce and hence are commanding higher prices. In Keynesian Theory of Trade Cycles, the marginal efficiency of capital has great significance than the rate of interest. Under the impact of the multiplier and acceleration effects, the process of increased investment and employment gets an upward trend. First, it is fluctuations in investment that cause changes in aggregate demand which bring about changes in economic activity (i.e., income, output, and employment). In spite of its various merits, the Hicksian theory of trade cycle suffers from the following weaknesses its fundamental shortcoming is that Hicks assumes a fixed value of the multiplier during the fixed phases of the cycles. Thus, a decline in investment by 100 crores will lead to the decline in income by 400 crores. According to Keynes investment decisions are taken by comparing the marginal efficiency of capital (MEC) or the yield with the real rate of interest (r). 4 Keynes’ Theory:-Keynes’ “General Theory” also provides an explanation of trade cycle, because trade cycle is nothing more than the fluctuations in income, output and employment. At this point, the marginal efficiency of capital will be high due to exhaustion of accumulated stocks and necessity to replace capital goods. Jevons’s theory, that the trade cycle was primarily due to the fluctuations in the bounty of the harvest, can be re-stated as follows. First, according to Keynes, marginal efficiency of capital is the most important factor that guides the investment decisions of the entrepreneurs. The General Theory by John Maynard Keynes (1936 ... type of investment has set a cyclical fluctuation in motion there will be little encouragement to a recovery in such investment until the cycle has partly run its course. But income does not increase or decrease through the multiplier process alone. The other factor that occupies an equally important place in Keynes theory is the “investment multiplier“. Finally, some critics like Hazlitt have pointed out that Keynes’ concept of the rate of interest does not tally with actual market conditions. Keynes has made three important contributions to the business cycle theory. Keynes observed that the duration of contraction is related definitely to the life of capital assets and the carrying costs of inventories. It has been observed that the rate of rise in income during the expansion phase is much more than the rate of fall of income during the contraction phase. Yet it is an incomplete explanation of the trade cycle. His main occupation was to provide the analytical tools for such a theory. TOS4. Keynesian economics is a theory that says the government should increase demand to boost growth. At the same time, the rate of interest may be low because of large cash balances with commercial banks or due to fall in the public liquidity preference. The marginal efficiency of capital falls below the current rate of interest and thus, the decline of investment is aggravated. On the other hand, contraction of investment will similarly lead to multiple contractions of income and employment. The changes in investment are made worse by the changes induced by the cycle itself in propensity to consume and the state can be described and analyzed in terms of the fluctuations of the marginal efficiency of capital relatively to the rate of interest.” The following points highlight the seven major criticisms of the Keynesian theory of trade cycle. However, for the active operation of investment multiplier, the cycle needs to be milder in magnitude than what it actually is. Nevertheless, he made a significant contribution to it. In fact, Clark had discussed the role of accelerator much before Keynes wrote his ‘General Theory’. Later on, Samuelson could show with the help of an exercise that multiplier accelerator interaction is capable of generating different types of trade cycle under different values. But then, the rate of interest   is very high, like all other prices and wages. According to Keynes, the cyclical fluctuations are caused by changes in the marginal efficiency of capital. Share Your Word File ‘Accelerator’ which can be called the process of induced investment is also instrumental in bringing about rapid changes in income. Keynes believes that the rate of interest could have prevented the collapse of the marginal efficiency of the capital and revives the confidence among the entrepreneurs, by exerting its pressure to reduce cost. According to Keynes, effective demand is composed of consumption and investment expenditure. This way he could explain simultaneously both growth and trade cycles. Psychological Theory in a New Form 3. John Hicks's 1937 paper Mr. Keynes and the "Classics"; a suggested interpretation is the most influential study of the views presented by J. M. Keynes in his General Theory of Employment, Interest, and Money of February 1936. The course of a business cycle, according to the Keynesian theory, runs as follows. Keynes’s Theory: The Keynesian theory of the trade cycle is an integral part of his theory of income, … Criticisms of the Keynesian theory of trade cycle 1. Hobson. This left his theory incomplete. changes in the rate of profit on current investment outlay and also due to changes in the rate of interest. Keynes did not formulate a separate theory of trade cycle, but he has given it as a by-product of his main theory of Income and employment propounded in the “General theory”. In the short period, the rate of interest will be stable and hence it is not responsible for causing cyclical fluctuations in trade cycles. The marginal efficiency of capital is sandwiched between rising costs of production on the one side and falling prices of finished goods in the other hand. Rather it was felt that the classical policy proved to be better during inflation. Changes in total expenditure will imply changes in effective demand and will lead to changes in income and employment in the country. According to Keynes, MEC forms the vital factor in guiding investment decisions of businessm… Keynes could not explain the latter. But his policy did not prove to be successful against inflation. The substance of Keynesian Theory of Trade Cycles  is that an initial investment outlay will generate multiple amount of income and employment under the influence of the multiplier and acceleration effects. There is an asymmetry here which Keynes did not record or analyse. Now, according to Keynes, consumption expenditure is relatively stable, and consequently it is the fluctuations in the volume of investment that are responsible for changes in the level of employment, income and output. On the other hand, contraction of investment will similarly lead to multiple contractions of income and employment. However, critics have found some weaknesses in the Keynesian Theory of Trade Cycles. According to him, a trade cycle occurs due to the fluctuations in the rate of changes in the marginal efficiency of capital. Therefore, in the Keynesian system fluctuations in total expenditure are responsible for fluctuations in business activity. A MODEL OF THE TRADE CYCLE 1. Keynes explained the cumulative nature of the upswing and downswing through his concept of investment multiplier. Here he seems to follow Keynes blindly regarding the stable consumption function. According to Keynes, trade cycle may be regarded Thus, the primary cause, of cyclical fluctuations is the marginal efficiency of capital (MEC) i.e. In the course of it the values expressed by the symbols on the ... sector in the post Keynesian theory of growth and distribution clarify some .

This asymmetry is due to the inactivity of accelerator in the downturn. John Maynard Keynes published a book in 1936 called The General Theory of Employment, Interest, and Money, laying the groundwork for his legacy of the Keynesian Theory of Economics. Keynes never enunciated an exclusive trade cycle theory. He reduced the problem to one of investment; only if investment is high enough will production be at a level which can produce full employment. Keynes's economic theory is based on the interaction between demands for saving, investment, and liquidity (i.e. But he did not care to introduce this aspect of the theory of capital in his theory of the business cycles. Besides, Keynes’ advocacy of fiscal policy to bring about business stability has been widely used. Von Hayek had given a theory of the business cycles which was entirely based on the changes in the nature of capital assets and product techniques during booms and depressions. Keynes’ Theory of Trade Cycles: Keynes doesn’t develop a complete and pure theory of trade cycles. 50. ADVERTISEMENTS: So long as the MEC is greater than r, new investment in plant, equipment and machinery will take place. Prices and Production, often seen as the companion volume to Monetary Theory and the Trade Cycle, developed in much greater detail the synthesis of Misesian business-cycle and Böhm-Bawerkian capital theory that Hayek first sketched out in "The Paradox of Saving." Fluctuations in the rate of investment are caused mainly by fluctuations in the MEC. As a starting point, the article reviews Keynesian business cycle theory and identifies the cause of economic crisis to blind investment and lack of demand. Keynes could not explain the latter. Content Guidelines 2. According to Keynes the fluctuations in the marginal efficiency of capital are the fundamental cause of fluctuation in trade cycles. Some of the criticisms are: 1. John Maynard Keynes Is The Great British Economist Of The Twentieth Century Whose Hugely Influential Work The General Theory Of Employment, Interest And Money Is Undoubtedly The Century S Most Important Book On Economics Strongly Influencing Economic Theory And Practice, Particularly With Regard To The Role Of Government In Stimulating And Regulating A Nation S Economic Life. Required fields are marked *. For instance, according to Keynes, in a period of recession and depression, the rate of interest ought to be high because of strong liquidity preference but precisely during this period, the rate of interest is low. Very soon goods are accumulated beyond the expectations of entrepreneurs and competition among them to dispose their accumulated stocks bring crash in prices. Despite its great impact, Keynes’ General Theory was a static equilibrium theory in the Marshallian short period in which the stock of capital goods, inter alia, was assumed to be constant. Prof. Hicks provided an explanation of the same in his theory of the trade cycles. Keynes could not explain this. In fact, it disturbs the equilibrium of the economy and thereby causes fluctuations in the economy. Hicksian Theory of Trade Cycle includes the Keynesian concept of saving-investment relation and the multiplier effect, Clarke’s principle of acceleration, Samuelson’s multiplier-accelerator interaction and Harrod-Domar growth model. But Keynes stuck to his liquidity preference theory of the rate of interest thereby rejecting the real theory of the rate of interest. 2. 5. Secondly, in Keynes’ theory, the rate of interest plays a minor role. He never intended to deal with the problem exhaustively. Keynes states, “The trade cycle can be described and analyzed in terms of the fluctuations of the marginal efficiency of capital relatively to the rate of interest.” According to Keynes, the level of income and employment in a capitalist economy depends upon effective demand, comprising of total consumption and investment expenditure. According to Keynes, “fluctuations in the level of national income and employment are due to changes in the volume of investment”. The article also indicates that fundamentally, the 1929 Great Depression and current global economic recession are the inevitable outcomes of capitalist mode of production. It is effective demand which determines the level of income and employment. It did not analyse well the nature of booms and as such could not provide a satisfactory anti-inflationary policy. He avoided discussing growth with business cycles. The interval which will elapse between the upper turning point and the start of recovery is conditioned by two factors: (i) The time necessary for wearing out of durable capital assets, and. No Explanation of the Trend of Growth with Business Cycles and Others. Keynesian Theory of Trade Cycle Criticism # 1. Keynes expresses the opinion that sizable fall in the rate of interest can do something to revive the confidence among the entrepreneurs by exerting pressure on the cost of production.

Periodicity means the period from depression to boom of the various trade cycles. Keynes has not offered a pure theory of trade cycle. John Maynard Keynes, one of the most influential economists of the 20th century, never worked out a pure theory of trade cycles, though he made significant contributions to the trade cycle theory. It brings about the sudden collapse of the MEC. Disclaimer Copyright, Share Your Knowledge If   such a case, Keynes’ theory of trade cycles approaches close to Pigou’s psychological theory, which assumes that the changing assumptions of entrepreneurs regarding future market conditions play a key role in the cyclical fluctuations of capitalist reproduction. Saving and investment are necessarily equal, but different factors influence decisions concerning them. The following Figure shows how trade cycle depends upon the marginal efficiency of capital, which according to Keynes, is the villain of the piece. Keynes worked out his General Theory as an answer to the obviously defunct classical theory that capitalism will always return to full employment in a state of equilibrium. Under consumption theory: The chief exponent of this theory is I.S. When an exceptionally large harvest is gathered in, an important addition is usually made to the quantity carried over into later years. The marginal efficiency of capital, therefore, collapses and brings about a crash in the investment market. Likewise, Keynes asserted that recovery will start only after the confidence of the investors in investment profitability gets restored. However, Keynes himself has pointed out that this has been sufficiently proved to be correct that the rate of interest does not have any influence on investment. Investment demand is very unstable and volatile and brings about business cycles in the economy. But Keynes did not incorporate this concept in his theory. the trade cycle. [94] [95] Today these ideas, regardless of provenance, are referred to in academia under the rubric of "Keynesian economics", due to Keynes's role in consolidating, elaborating, and popularizing them. Keynes believes that at this stage a reduction in the rate of interest is neither easy nor adequate to restore confidence and revive investment. However, this important factor depends on entrepreneurs’ anticipation of future prospects that further depend upon the psychology of investors. Keynes could not explain the latter. As a result, the entrepreneurs may borrow funds from banks and make fresh investments. According to him, trade … We can conclude by saying that Keynes gave us valuable insights into the theory of business cycle in his ‘General Theory’. Part -1 Sunspot theory Under consumption Over investment Keynesian theory Samuelson accelerator theory. During the period of expansion the marginal efficiency of capital is high. 1 Dynamic Keynesian economics 2 found its first expression in trade cycle theory (or business cycle theory in American terminology).

Welcome to EconomicsDiscussion.net! money). Keynes advocated a cheap- money policy along with the policy of public works for fighting a depression. In fact, Keynes’ ‘General Theory’ was depression economies. The substance of Keynesian Theory of Trade Cycles is that an initial investment outlay will generate multiple amount of income and employment under the influence of the multiplier and acceleration effects. Keynes told us that the major cause of the burst of a boom is the over-optimism of the business community. Our mission is to provide an online platform to help students to discuss anything and everything about Economics. The theory here presented is essentially similar to all those theories which explain the Trade Cycle as a result of the combined operation of the so-called" multiplier " and the investment demand function as, e.g., the Businessmen are optimistic; investment goes on at a rapid pace; employment is high; and incomes are rising, each increment of investment causing a multiple increase of income. It was on the foundations laid down by Keynes that Professors Hicks, Goodwin and Mathews could build the modern theories of the trade cycle. Sunspot theory Offered by Mr . J.M. 1  Keynesians believe consumer demand is the primary driving force in an economy. In this lie did commendable work. This brings Keynes’s theory very near to the psychological theory of trade cycles given by some classical writers. Privacy Policy3.

This deficiency in Keynes’ analysis was removed by Professor Roy Harrod who distinguished between three rates of growth of the economy the actual rate of growth, the warranted rate of growth and the natural rate of growth. The General Theory, as it is known to all economists, cut through all the Gordian Knots of pre-Keynesian discussion of the trade cycle and propounded a new approach to the determination of the level of economic activity, the problems of employment and unemployment, the causes of inflation, the strategies of budgetary policy.
