keynes theory of income and employment

Keynes used his income‐expenditure model to argue that the economy's equilibrium level of output or real GDP may not corresPond to the natural level of real GDP. Whatever the path taken, the amount of new spending required to push the national income upward by Rs. Alternatively, we can say (following Keynes) that the equilibrium level of income is reached when planned saving is equal to planned investment. In fact, for these two reasons, the savings and invest­ment plans of the two groups may remain unfulfilled and there may be divergence between planned sav­ing and planned investment. Output ex­pansion will continue until full employment is reach­ed. Since the fulfilment of the equilibrium condition of one approach implies the fulfilment of that of the other approach the two approaches are equivalent. And the MEC of a particular type of asset shows what the entrepreneur expects to earn from one more asset of that kind compared with what he has to pay to buy it. Keynesian theory of employment was a reaction against the classical economics. 800, i.e., Rs. In Fig. With increases in income the amount of dis-saving is reduced and a point is reached when saving is zero, i.e., neither positive nor negative. So it is taken as fixed in equation (2). Total, or aggregate, spending refers to the total spending for all new goods and services by households, businesses, govern­ment units, and foreign buyers combined. 800. We have examined how national income is de­termined by these two approaches. Investment is Rs. At this level of income, households are de­sirous or saving only Rs. The size of a change in the flow of income initiated by every change in injection or withdrawal, other things remaining the same, will depend upon the community’s MPC or its counterpart, its marginal propensity to withdraw income. 1,000 per month and the marginal propensity to consume (MPC) is 4/5 (i.e., a constant ratio was the proportion of the increase in income spent on consumption) total incomes will raised by Rs. Here the total income of households must be Rs. b. decrease in nominal income, but no change in real output . Moreover, the motives for saving and invest­ment are different. Keynes, however, got personally involved in only a few of them. This is indicated by point C in Fig. Keynesian Theory was given by Keynes when 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. (When national income moves up or down we speak of a state of disequilibrium). The word stands for the numerical coefficient showing how much above unity is the increase in income resulting from each increase in investment. In Keynes’ model ΔY = m (ΔI). If we let ‘m’ stand for the multiplier we can write. According to Keynes, the volume of employment in a country depends on the level of effective demand of people for goods and services. The central problem in macro economics is the determination of income and employment of a nation as a whole. The publication of The General Theory of Employment, Interest and Money (hereafter referred to as GT), in early 1936, generated several public debates. 580 when the rate of interest is 4% and investment is Rs. There is very little chance of these plans being equal to each other within the same time period. John Maynard Keynes is often referred to as the father of macroeconomics. This means that Keynes visualized employment/unemploy­ment from the demand side of the model. Thus in Keynes’ model investment is given. But when the two are not equal, certain forces in the economy will be at work that cause national income to change in the desired direction. The income-expenditure approach is illustrated in Table 34.1. Since consumption and saving are the two sides of the same coin, the determinants of consumption are also the determinants of saving. Households buy far more goods and services than do businesses, government units, and foreign purchasers combined. So the desire of on entrepreneur to undertake such risks will depend on their expectations regarding the future. 76. 400 equilibrium income, and an 8% rate is consistent with a Rs. Keynes’ theory of employment is a demand-oriented theory. Introduction. It is an injection into the circular flow of national income. (2) There may be unemployment even when national income is in equilibrium. The same level of income can be found out by solving the following two simul­taneous equations: The first is the equation of the planned expenditure line and the second is the equation of the 45° line. We may now examine why it is so. Keynes Theory of Income and Employment; The theory has reference in the short run since the stock of capital, technique of production efficiency of labor, size of population etc are assumed to remain constant in the short run. The situation of ‘Effective Demand’: According to Keynes, Equilibrium level of employment is determined when Aggregate Supply is equal to Aggregate … We know that, Y = C + S. Dividing both sides of the equation by Y we get. With planned invest­ment exceeding planned saving, planned ex­penditure would exceed planned income resulting in a fall in the value of stocks (inventories). The investment figure is, therefore, lowered by Rs. The Circular Flow with Saving and Investment: Saving Investment Equality vs. Saving-Investment Equili­brium. The amount spent on consumption must be the same as the value of consumer goods produced assuming that savings (the supply of capital goods) equal investment (the demand for capital goods). Saving is mainly done by households but in­vestment activities are largely carried out by business firms. Investment requires that an amount of current consumption is sacrificed (i.e., a portion of income is saved) so as to release the resources to finance it. The relationship between spending and output, employment, and income is summarised in Table 18.1. The rate of return over cost, r, is called the MEC. The MEC decreases as the amount of invest­ment increases. Because individuals do not usually alter their expenditure patterns from year to year, aggregate house­hold spending on new goods and services, which is technically termed personal con­sumption expenditures, tends to fluctuate very little as it grows over time. If they are forced to hold stocks of finished goods due to low demand, a cutback in production is inevitable. As and when they do this, national income rises. Since saving is a leakage it is marked with a minus sign. In the first place, households will not be able to buy all that they want to buy. 200 crores in or­der to meet excess demand of the same amount. Equilibrium income is Rs. The premise of full employment runs throughout the whole structure of this theory. (A) The British Economist John Maynard Keynes in his masterpiece ‘The General Theory of Employment Interest and Money’ published in 1936 put forth a comprehensive theory on the determination of equilibrium aggregate income and output in an economy. In fact, we have observed that when these two magnitudes are not the same, national income must rise or fall. We assume that firms plan an output of Rs. They may take weeks or months to spend the relevant proportion of their additional income at each stage of the process. If for example, income rises by Rs. The marginal propensity to consume (MPC): It is the proportion of an addition to income that is spent on consumption. It is as if the economy has come up against the wall which prevents it from going any further. The simple Keynesian analysis of income determination tells us something about the causes and direction of changes in the circular flow of income but nothing about the size of those changes. When people want to buy more goods than is being pro­duced there will be a pressure on national income to rise, as is indicated by the arrow to the left of point A. On the other hand, people with very high incomes cannot spend all their income on goods and services. So the theory explained that, Income is the function of employment. Suppose, now national income is Rs. 140/0.20 = Rs. Investment may be gross or net. In the classical model, the labour market determined the level of output and therefore, the position of the vertical aggregate supply curve. If the rate of interest falls, one would expect more investment to be undertaken. Let us consider an extreme situation. 18.6), because all investment is autono­mous. This imbalance between the two conflicting forces—the income-increasing forces of investment and income-decreasing forces of saving —tend to cause national income to rise. Financial in­stitutions operating in the capital market act as a link between households and business firms. 34.1 is the same as the level of income, Ye where the saving line intersects the investment line in Fig. 10,000 crore and saving is Rs. 520 when the rate of interest is 6% and investment is Rs. In all non-socialist countries the major portion of saving originates from the household sector. Before we proceed further we have to note four important definitions. The additional output will then permit business firms to sell more without a further reduction of stocks. 2. Source: The General Theory of Employment, Interest and Money by John Maynard Keynes, Fellow of the King's College, Cambridge, published by Harcourt, Brace and Company, and printed in the U.S.A. by the Polygraphic Company of America, New York; First Published: Macmillan Cambridge University Press, for Royal Economic Society in 1936; The economy is therefore in equilibrium be­cause injections are equal to leakages (withdrawals). Producers find it difficult to sell their entire output at current prices. Or, some people may depend on others for survival. 50 + 0.80Yd; I = Rs. The income earned will either be used for consumption purposes or saved. It needs to be noted that Keynesian theory is supposed to apply under short run and perfect competition. The firms’ plans are the same as they were in Example 1. According to Keynes, the volume of employment in a country depends on the level of effective demand of the people for goods and services. (1) Savings and investment are different activities car­ried out by different groups of people and. Consumption expenditure takes place during this time by drawing down past savings. Keynes’ analysis of general unemployment is based on the concept of aggregate (or total) demand in the economy. The implication is very simple: in a private two-sector economy people wish to buy the total output that firms succeed in producing. If investment increases, aggregate demand also increases and, at the end, we observe an increase in employment and income. John Maynard Keynes is widely misunderstood not because he is misread, but because so few take the time to read him. It refers to physical or real investment. The impact of 'Excess Demand' under Keynesian theory of income and employment, in an economy are: a. decrease in income, output, employment and general price level . This latter depends upon the relative proportions of income withdrawn from the circular flow or passed on through expenditure on consumption. On the contrary, if people save less and spend more on con­sumption goods, business firms will find their stock levels falling. Thus, the producers of those capital goods (such as, textile producing machines) must be paid, i.e., they receive income. Let us go back to Table 34.1 for the sake of il­lustration. If saving and investment are equal, the flow will remain unchanged because the amount withdrawn from it is equal to the amount of injected into it. The consequent pressure of excess demand will cause prices to rise, production to expand, and the demand for factors of production to increase. The other factor affecting investment decisions is the expected rate of return on investment expenditure—or, what Keynes calls, ‘the marginal efficiency of capital’. This shows that as income increases, the slope of the consumption schedule decreases, i.e., as income increases, MPC gradually falls. where C stands for the supply of consumption goods and S for the supply of capital goods. Effective demand denotes money actually spent by the people on products of industry. It is that part of society’s current income which is not spent on consumption goods. With planned saving and investment being equal, the economy is in-equilibrium. Investment is an injection into the circular flow of income and if it equals savings, the leakage caused by the latter will be offset and can be ignored. Since production is profitable, output will increase to meet the extra demand. This return (or revenue) will not fully materialise until some years have passed. It was Keynes who first noted that what people plan to do and what they succeed in doing may be two different things. The classical theory assumed the prevalence of full employment. Investment expenditure is a component of aggregate demand and an addition to the circular flow of income. Since equilibrium refers to a position of rest or balance, national income is said to be in equilibrium when it remains unchanged at a particular level, i.e., when there is no tendency for it either to rise or to fall. Government persuade on the economy is nil. Basically, expansions and contractions in economic activity, or changes in real output, are caused by changes in total, or aggregate, spending. 2. Let us pick up points/and d on the SS’ curve. 300 crores. 800 + Rs. Thus, a reduction in spending leads to a recession, or contraction in economic activity, because of its dampening effect on output, employment, and income. This means that, in order to meet the demands of the households, firms have to take Rs. With planned saving and investment being equal, the economy is in a state of equilibrium—there are no forces at work changing the level of output or income. Content Guidelines 2. The General Theory of Employment, Interest, and Money By John Maynard Keynes Feburary 1936 Table of Contents • PREFACE • PREFACE TO THE GERMAN EDITION • PREFACE TO THE JAPANESE EDITION • PREFACE TO THE FRENCH EDITION Introduction 1. If the economy stays at OF, then full employment will not be achieved, i.e., there is unemployment. Any stock changes are regarded as changes in investment. Thus, it is a short-run theory and provide solution to short-run employment problem. Apparently the above analysis is true at all points of time. The nineteen-thirties was the most turbulent decade that set off the most rapid advance in economic thought with the publication of Keynes’s General Theory of Employment, Interest and Money in 1936. From Keynes’ model we have arrived at a general result that national income is in equilibrium where aggregate planned expenditure is equal to actual out­put (i.e., actual national income). 3200 crores, planned saving would exceed planned investment. However, in the simple. But, as income increases, saving increases, so saving curve must be a rising one. 800 crore worth of goods. Keynes' approach was a stark contrast to the aggregate supply -focused classical economics that preceded his … That is why the saving live starts from the negative axis. But this is not desirable for obvi­ous reasons. In Keynes’ model the equilibrium level of national income is the level at which aggregate demand is equal to output (aggregate supply). vi The Economics of Keynes: A New Guide to The General Theory 3. Here we assume that all saving is household saving. There­fore, a more realistic consumption function would be of the type shown in Fig. They, therefore, find that they end up making investment of Rs. So it log­ically follows that whenever planned saving is less then planned investment, national income tends to rise. Since income is the result of employment of resources, including manpower, this theory is also known as the Keynesian theory of income and employment. THE POSTULATES OF THE CLASSICAL ECONOMICS 3. The output produced will be either for current use or will be added to the country’s stock of investment goods. Only at Ye, it is in equilibrium and only at this level of income desired (planned) saving is equal to desired (planned) invest­ment. Keynes’ income-expenditure approach determines the equilibrium level (value) of national income at that point. Thus a divergence between saving and investment is a logical possibility. What is the logic of this equilibrium? This process is facilitated by a multiplied change in income— which operates both in an upward and down­ward direction. 460 when the rate of interest is 8% and investment is Rs. (In reality, however, what is important in causing income change is the relationship between I and S.). Share Your PDF File Conversely, at any level of income above OYe, aggregate demand is less than output. 1600 crores when planned expenditure is Rs. The economy may expand up to the income level OZ, but it cannot go beyond that because there is then full employment and the resources are not available for further expansion. It was Keynes who first discovered the relation between planned and actual figures. Again the firms’ plans are the same as previously, but this time households plan to spend Rs. (b) Planned spending equals the value of output. These determinants are not separate from each other. Planned sav­ing is the difference between income and planned con­sumption. Beyond this point, saving becomes positive and rises as income rises. However, by ‘classical economists’, Keynes meant the followers of David Ricardo including John Stuart Mill, Alfred Marshal and Pigou. Since the two groups (i.e., savers and investors) are able to save and invest exactly what they plan to at an unchanging level of national income, they have no reason to alter their behaviour. What is the logic of this equilibrium? The table gives a consumption function from which saving plans can be obtained. We know that saving is undertaken by con­sumers and investment by entrepreneurs. Substituting (8) and (7) into (9) we get: Equation (10) states that the equilibrium level of national income is found out by dividing autonomous expenditure by the MPS. Households do al­locate their income between consumption C and sav­ing 5. “The amount of current investment will depend, in turn, on what we shall call the inducement to invest; and the inducement to invest will be found to depend on the relation between the schedule of marginal efficiency of capital and the interest rates on comes of various maturities and risks.”. In the opposite situation when actual income is greater than equilibrium income, the saving line lies above the investment line. 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. Keynes in his eminent work “General Theory of Employment, Interest and Money” not only criticised the classical Say’s law but also propounded a new theory of income and employment. 52, rais­ing equilibrium income through the multiplier effect from Rs. It is not too much to expect that every-thing will continue in future as at present. Another way of reaching the same result is by concentrating attention on the proportion of extra income withdrawn (5). Thus, saving causes the flow of income to become smaller. Therefore, the slope is given by which is indeed the marginal propensity to consume (MPC). Welcome to! At OX, output (XA) is greater than aggregate demand (XB). Investment is, therefore, a risky matter. Thus, there is an inconsistency between savings and investment plans. It is interesting to note that both give the same result. 1,000 is invested in the new machine, the annual return is Rs. Finally, investment in the provision of social capital (such as roads, schools, hospitals, etc.) (LM is sometimes referred to as the ‘ inflationary gap’.). In Fig. Keynesian economics is a theory of total spending in the economy (called aggregate demand) and its effects on output and inflation. 10 crore rise in the value of output in the coming year. Keynes says that, the lenth of long run is not clear in Say’s law. Saving is the supply of capital and investment is the demand for capital. When considering whether to undertake expenditure an entrepreneur will compare the cost of the venture (such as setting up of a textile mill) and the revenue he expects to get from it. The 45° line is called the income line (or guideline) because it shows different levels of income. The economy is said to in equilibrium. In Keynes’ model we have the following three equations: Here b is the MPC and investment is autonomous. Thus, a 10% rate of interest is consistent with a Rs. They regarded unemployment as a temporary phenomenon and assumed that there is always a tendency towards full employment. Since supply = produc­tion ± stocks, the only way to fulfil consumption and investment plans in this case is by purchasing exist­ing stocks of goods. According to Keynes any change in autonomous spending will have a multiplier effect. The fall in stocks can be regarded as un­planned disinvestment, giving a realised invest­ment figure of 50 – 20 = 30 (which is the same as realised savings). Therefore, the multiplier only tells us the position which will be reached by an economy after a lapse of time if the rate of injection remains constant. That ‘someone else’ will, in turn, save part of the new income and spend the remainder, so that another person (or persons) will receive additional income. 18.1, one can establish the relationship between APC and MPC. Now if we substitute equation (1) into equation (4) we get: Further substitution of equations (2) and (3) in equation (5) yields the following: Here b is a constant and I is also a constant. 5,000. Business firms generally do not wish to exhaust their stocks. 1,000 and the MPC is 4/5, the final increase in income will be Rs. So, income will now rise further by this amount and consumption by 4/5th of Rs. If buyers do not spend their money on products, sellers will not produce those products for the market. Modern income analysis shows that an increase in investment will increase national income by a multiplied amount — by an amount greater than itself. Moreover, since MPC + MPS = 1, the multiplier can be found by using following formula: where s is the MPS. Thus, the slope of the consumption schedule gives us the MPC. Since income is the result of employment of resources, including manpower, this theory is also known as the Keynesian theory of income and employment. Thus, if total spending were to decrease, output would decrease; if total spending were to increase, output would increase; and if total spending remained unchanged, output would not change. If we add Rs. Assuming that planned investment is autonomous and that all household plans are realised, an equili­brium level of income can be calculated. If their view of future prospects is pessimistic they will be less willing to spend more on investment. In our example this would be 1/(1 – 4/5) = 5. The result is that the Rs. It is found out by dividing total savings (S) by total income (Y) or APS = S/Y. In the absence of a govern­ment sector and taxes, the value of output equals the household sector’s disposable income so that Yd = Y. Here, LM is the change in income and MN the change in consumption. National Income remains unchanged and is said to be in equilibrium. The fall in stocks can be regarded as un­planned disinvestment, giving a realised investment figure of 50 – 20 = 30 (which is the same as actual saving). The slope of the consumption schedule— denoted by b in the diagram — is given by MN/LM. Investment expenditure is normally defined as consisting only of private sector investment spending. In this case C0 = R/e, so that, if the machine costs Rs. However, the two lines intersect at only one point and the point at which the equilibrium level of national income oc­curs. (b) Substituting, we have Y = (Rs. Since there is no spending firms will receive no income. (a) Planned saving equals Yd — C; and since C = Rs. Share Your Word File The explanation of the apparent conflict is the essence of the Keynesian theory of income determi­nation. Business firms are just able to sell their entire current output, with­out adding to or subtracting from their stocks. The income obtained from the production of the national output is distri­buted to the various factors of production employed in the production process and, so, national income and national output are always and necessarily equal. Keynes Theory Of Income And Employment. Therefore effective demand equals national income. However, the multiplier process takes time to work itself out. Thus Y in equation (6) is indeed the equi­librium level of income. Suppose the household sector’s planned consumption is C = Rs. A fall in the rate of interest to r1, (say, 15%), increases the amount of profit investment to OI1. Privacy Policy3. 100 crore worth of unsold goods will be added to stocks. 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. This is known as the saving- investment (or leakage-injection) approach. Since both will be fulfilled there will neither be excess demand (and the consequent out­put expansion) nor excess supply (and the consequent output contraction). Now 1 – b = s, so we can write. 100 crore. 34.5, e is the equilib­rium point of national income. 1 Equilibrium level of income and employment is established at a point where AD = AS. The table gives a consumption function, from which saving plans can be obtained.
