keynes' theory of trade 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. Thus, these are the main ingredients of the hick’s model. Keynesian economics is considered a "demand-side" theory that focuses on changes in the economy over the short run. As a result, there will be unemployment of resources, both labour and capital. At this point, the marginal efficiency of capital will be high due to exhaustion of accumulated stocks and necessity to replace capital goods. Keynes Theory of Business Cycles Introduction A business cycle refers to a phenomenon of alternating periods of expansion and contraction in economic activity. But he explains those factors which brings changes in income, output and employment. According to the Keynesian model, substantial economic slumps come from falling aggregate demand—the sum of overall consumption, investment, and government spending within the economy. In terms of graph, a sudden fall in the marginal effi­ciency of capital causes on leftward shift in the investment demand curve, for example from I0I0 to I1I1 in Figure 27.3 resuming in decline in investment from I0* to I1* at the given rate of interest. Keynes’ General Theory, the resolution of this question was regarded as one of the main outstanding challenges to economic research, and attempts to meet this challenge were called business cycle 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. Propensity to consume being more or less stable in the short run, fluctuations in aggregate demand depend primarily upon the fluctuations in investment demand. According to Keynes, MEC forms the vital factor in guiding investment decisions of businessm… 669-672) And, then, Hawtrey’s very detailed summary and critique of Hayek’s “The Pure Theory of Capital” after it appeared in 1941. Watch Queue Queue 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. Yet it is an incomplete explanation 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. Credit expansion should correspond to a … 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. A. Asimakopulos (1991) Keynes's General Theory and Accumulation.Cambridge, UK: Cambridge University Press. There is heavy economic activity everywhere in the primary, secondary and tertiary sectors of the economic system. The classical economic theory promotes laissez-faire policy. Thus, these are the main ingredients of the hick’s model. During an economic expansion two factors eventually work to cause invest­ment to fall. Privacy Policy 8. Now, the multiplier works to magnify the effect of increase in investment on raising aggregate demand. 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. 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. Keynes, John Maynard. A long period of time is necessary for existing capital to depreciate because most capital goods are durable as well as irreversible. Definition of Trade Cycle or Business Cycle. Thus, just as the collapse of marginal efficiency of capital is the main cause of the upper turning point, similarly the lower turning point, i.e., changes from recession to recovery is due to the revival of the marginal efficiency of capital, that is, expected rate of profit. The marginal efficiency of capital, therefore, collapses and brings about a crash in the investment market. Besides, Keynes' advocacy of fiscal policy to bring about business stability has been widely used. According to Keynes, effective demand is composed of consumption and investment expenditure. Kaldor’s Model of the Trade Cycle: Nicholas Kaldor built a model of the trade cycle based on the Keynesian terminology of saving and investment. Keynes' "General Theory" trade cycle and foreign exchange. They cause a further fall in the marginal efficiency of capital. Introduction. Under the impact of the multiplier and acceleration effects, the process of increased investment and employment gets an upward trend. 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. Sunspot theory Offered by Mr . All these factors work to lift the economy out of depression and puts it on the road to prosperity. Sunspots appear on the face of the sun. In the above example, when income has risen by 400 rupees, people’s spending power has risen by an equivalent amount. Content Guidelines 2.

All this leads to an increase in profits with the result that businessmen will be induced to expand their productive capacity and will install new plants, i.e., they will invest more than before. Pessimistic overtakes businessmen. Chapter 12 of Keynes’s General Theory entitled “Notes on the Trade cycle’ serves as a link between his general theory of employment and conventional subject matter of business cycle theory… Sunspot theory Trade cycles are caused by sun spots. Just as the expected rate of profit was pushed down by the growing abundance of capital during the period of boom, similarly as the stocks of capital goods are depleted and there grows a scarcity of capital goods, then the ex­pected rate of profit rises thereby inducing the businessmen to invest more. 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. ...

A Keynesian believes […] During the period of expansion the marginal efficiency of capital is high. Thus with the emergence of scarcity of capital, marginal efficiency of capital rises which boosts investment. Investment depends upon two factors: (a) marginal efficiency of capital, and (b) the rate of interest. 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. This type of fluctuation is known as the business or trade cycle. In the earlier studies of the trade cycle, notably by Jevons, an explanation was found in agricultural fluctuations due to the seasons, rather than in the phenomena of industry. In this respect, Keynes, far from being the economist for society, even less for the cause of labour, cleaves strongly to the interest of capital. Of course, even before Keynes, it was believed that the fluctuations in the investment demand have something to do with the business cycles, but a systematic exposition was lacking. These models have been developed into the real business-cycle theory, which argues that business cycle fluctuations can to a large extent be accounted for by real (in contrast to nominal) shocks. The accelerator describes this relation between an increase in income and the resulting increase in investment. Keynesian economics (/ ˈkeɪnziən / KAYN-zee-ən; sometimes Keynesianism, named for the economist John Maynard Keynes) are various macroeconomic theories about how economic output is strongly influenced by aggregate demand (total spending in the economy). Thus, the multiplier process magnifies the effect of decline in investment expenditure on aggregate demand and income and further deepens the depression. Since wage and price flexibility does not ensure the recovery of the economy out of the state of depression, Keynes thinks that marginal efficiency of capital must rise to stimulate investment. 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. Therefore, in the Keynesian system fluctuations in total expenditure are responsible for fluctuations in business activity. Declining trend of investment, according to Keynes, raises doubts about the prospective yield on capital goods which is more important factor determining marginal efficiency of capital than cost of investment projects and rate of interest. Finally, some critics like Hazlitt have pointed out that Keynes’ concept of the rate of interest does not tally with actual market conditions. It is important to note that, in Keynes’s views, wages and prices are not flexible enough to offset the decline in investment expenditure and thereby restore full employment. These pessimistic expectations cause stock prices to tumble which work like adding fuel to the fire. Thus, the decline in stock prices reduces autonomous consumption demand of households. 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”. Historical Background 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.

On the other hand, if the level of aggregate demand is low, smaller amount of goods and services can be sold profitably. Required fields are marked *. What causes fluctuations in aggregate demand? The total expenditure is equal to the national income, which is … As a result, the theory supports the expansionary fiscal policy. It follows from above that besides the rise in cost of capital goods and rise in rate of interest towards the end of the expansion phase, it is the fall in expected prospective yield that reduces the marginal efficiency of capital and causes investment demand to fall.

Thus, over time as depreciation of capital stock occurs without replacement and also some existing capital equipment becomes technologically obsolete, the size of capital stock declines. Useful notes on Keynes’ Monetary Theory – Explained! However, for the active operation of investment multiplier, the cycle needs to be milder in magnitude than what it actually is. The course of a business cycle, according to the Keynesian theory, runs as follows. The marginal efficiency of capital falls below the current rate of interest and thus, the decline of investment is aggravated. Content Filtrations 6. 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). Here he seems to follow Keynes blindly regarding the stable consumption function. In Keynesian Theory of Trade Cycles, the marginal efficiency of capital has great significance than the rate of interest. VII. 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.

Keynes’s theory was the first … The idea that it is the fluctuations in investment that bring about- the fluctuations in the level of economic activity is an important contribution made by Keynes. The other factor that occupies an equally important place in Keynes theory is the “investment multiplier“. Investment demand is very unstable and volatile and brings about business cycles in the economy. 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. First, during the expansion phase increase in demand for capital goods due to large-scale investment activity leads to the rise in prices of capital goods due to rising marginal cost of their production.
