Investment depends upon the marginal efficiency of capital on the one hand and the rate of interest on the other. 17: Let’s step back for a second. Indeed, it so scandalized its readers at the time that it was “convicted as a nuisance by the grand jury of Middlesex in 1723, which stands out in the history of the moral sciences for its scandalous reputation.”. For it is, so to speak, a game of Snap, of Old Maid, of Musical Chairs — a pastime in which he is victor who says Snap neither too soon nor too late, who passes the Old Maid to his neighbour before the game is over, who secures a chair for himself when the music stops. In The General Theory of Employment, Interest and Money, the British economist John Maynard Keynes argues that the belief that markets naturally tend towards full employment is a fallacy, and that state interventionism is therefore necessary to overcome economic slumps. It is striking how few economists have thought this problem through.”), 12: As we noted before, capitalists invest if they expect future sales to be high. In the analysis of trade cycle, theory of multiplier is an important tool Keynes’s policy of public works was based on his belief in the working of the multiplier vigorously in the depression phase. Well, until you have full employment obviously. Comments on the four discussions in the previous issue of points in the General Theory, 209. To say that net output to-day is greater, but the price-level lower, than ten years ago or one year ago, is a proposition of a similar character to the statement that Queen Victoria was a better queen but not a happier woman than Queen Elizabeth — a proposition not without meaning and not without interest, but unsuitable as material for the differential calculus. Simple Income Determination 7. The actual, private object of the most skilled investment to-day is “to beat the gun”, as the Americans so well express it, to outwit the crowd, and to pass the bad, or depreciating, half-crown to the other fellow. There were a few direct policy implications of Keynes’ theory. So it’s how much people spend that determines employment. In this event a scheme for the higher taxation of large incomes and inheritances might be open to the objection that it would lead to full employment with a rate of accumulation which was reduced considerably below the current level. Now the State will still have to guide things; it seems unlikely that just controlling interest rates will be enough to ensure this utopian state of affairs. But now people invest their money in the stock market, which revises its profitability estimates minute-by-minute. In other words, as employment goes up and we run out of skilled truck-builders, we say the truck factory is getting less efficient. And even if they were willing to wait, why should they trust you? An intrinsic reason for such scarcity, in the sense of a genuine sacrifice which could only be called forth by the offer of a reward in the shape of interest, would not exist, in the long run, except in the event of the individual propensity to consume proving to be of such a character that net saving in conditions of full employment comes to an end before capital has become sufficiently abundant. But spending can have negative effects as well. And obviously you’ll keep borrowing money and investing it until your expected return reaches the market rate of interest. 3: When people get money, they spend some of it — but not all of it. Keynes was writing about the short-period problem of depression. Or if there is some monopoly clement somewhere, then its degree remains unchanged. Thus, after all, the actual rates of aggregate saving and spending do not depend on Precaution, Foresight, Calculation, Improvement, Independence, Enterprise, Pride or Avarice. Keynes’ economic thinking and economic policy at once became popular. But you can’t jump-start it just by lowering interest rates, since the real problem is expected return. But the worst part of the international gold system is the way it sets countries against one another. Besides the concept of income, another concept which continued to bother Keynes was the choice of units for the purpose of macroeconomic analysis and measurement in the absence of which he could never go along conveniently. Finally, with the additional demand equipment and so on will have to be replaced, raising marginal costs. Moreover, the necessary measures of socialisation can be introduced gradually and without a break in the general traditions of society. Another thing the classical economists long mocked were laws against usury. But, soon or late, it is ideas, not vested interests, which are dangerous for good or evil. As a result, it seems likely that the State, which can calculate these things with an eye to the long-term and the social good, will take over more and more of the job of organizing long-term investment. Keynes has found a crack in the classical theory. Saving doesn’t lower the interest rate and thus increase investment — an increase in money does that. Among Gesell’s proposals are the notion of stamped money (money you have to pay to get stamped regularly to keep it valid currency) which is a way of discouraging people from hoarding. A hefty tax on each trade might be the best way to discourage speculation and thus improve the functioning of the market. Since this seems so basic, Keynes is puzzled at how it’s been so ignored: The completeness of the [classical] victory is something of a curiosity and a mystery. And then what do we do? We have to accept them as an inevitable result of applying to the conduct of the State the maxims which are best calculated to “enrich” an individual by enabling him to pile up claims to enjoyment which he does not intend to exercise at any definite time. It will be, moreover, a great advantage of the order of events which I am advocating, that the euthanasia of the rentier, of the functionless investor, will be nothing sudden, merely a gradual but prolonged continuance of what we have seen recently in Great Britain, and will need no revolution. The equilibrium level of income in the economy can be determined only with reference to a point on this line. The only thing that could work is a one-time decrease in everyone’s wages to a new level, but that a) is never going to happen in a democracy and b) unfairly penalizes wage-earners over everyone else. Domestic investment is encouraged by the interest rate and foreign investment by the balance of trade. [AS: This is the first use of that suspicious definition.]) 1) You can’t just go ahead and make it — it can’t be “grown like a crop or manufactured like a motor-car.” 2) You can’t reclaim it from use for other purposes — it doesn’t have any. It says the book is an attempt to show that classical economics (basically that summarized by Alfred Marshall, including Ricardo, Mill, Edgeworth, and Pigou) addresses only a special case of the economy, while this book outlines a more general theory. OK, so you promote investment, but how much investment? Hitherto the increment of the world’s wealth has fallen short of the aggregate of positive individual savings; and the difference has been made up by the losses of those whose courage and initiative have not been supplemented by exceptional skill or unusual good fortune. “It is as though a farmer, having tapped his barometer after breakfast, could decide to remove his capital from the farming business between 10 and 11 in the morning and reconsider whether he should return to it later in the week.” And since much new investment money is raised on the stock market, it’s these estimates which influence new investment. Still, the book isn’t exactly a smooth read. (Land can’t be grown either, but if we really needed to we could free some up by moving closer together. For the book is, indeed, truly brilliant, a definite work of genius. Then the money can’t go to hire more people so it just goes to bid up the prices of things, creating inflation. The remaining chapters of Keynes's book contain amplifications of various sorts and are described later in this article. [AS: This seems to be a little controversial (and, indeed, tends to be a bit confusing), but let’s just accept it as a quirky definition, not any kind of factual claim. 22: Why are there trade cycles, aka business cycles, aka booms and busts? These propositions contain the essentials of the general theory’ of employment. Secondly, he could very nicely provide reasons for departures from the policy of balanced budgets. Dr. Marshall in his Principles of Economics had defined national income as follows: “The labour and capital of a country, acting on its natural resources, produce annually a certain net aggregate of commodities, material and immaterial, including services of all kinds… and net income due on account of foreign investments must be added in this is the true net annual income or revenue of the country, or the national dividend.”. An important fact about the consumption function is that it is stable in the short run because the consumption habits of the community remain more or less stable in the short run. Prof. Fisher’s definition was better than both Dr. Marshall’s and Prof. Pigou’s in as much as it was nearer the concept of economic welfare because welfare depends upon the goods and services made available to the individuals of the community. Let investment be 20 crores of rupees whatever the level of income. That said, today’s decisions are based on the conditions of today and expectations about tomorrow — not on past expectations or the conditions of the past. Perhaps this is why it has a reputation for being a very tough book — so difficult that even economists can’t follow it. We can add it to the various levels of consumption shown by the consumption function and get the C +I (total expenditure) line. Since we are taking each commodity in turn as the standard, the returns on each commodity must be reckoned in this context as being measured in terms of itself. — III. … Moreover, if such a situation were to arise, it would mean that the public authority itself could borrow through the banking system on an unlimited scale at a nominal rate of interest.” [AS: The US, however, is in this situation right now (2009).]. 70 crores while their income is only Rs. Virtue and vice play no part. Its main tools are government spending on infrastructure, unemployment benefits, and education. “Pyramid-building, earthquakes, even wars may serve to increase wealth, if the education of our statesmen on the principles of the classical economics stands in the way of anything better.”. It is convenient to mention at this point the strange, unduly neglected prophet Silvio Gesell (1862-1930), whose work contains flashes of deep insight and who only just failed to reach down to the essence of the matter. However, this period was relatively short because Keynes's heart attack in 1937 meant that he was out of action … The concept of underemployment equilibrium is the most revolutionary idea put forth by Keynes. If the expected rate of profitability (MEC) of an additional unit of capital asset is high, private investors would be prepared to invest, otherwise not. The general apparatus of the Keynesian theory of employment can be briefly summarised in the following form: We start explaining the concepts from the top of the format given above. The limitations of Keynes’s theory and policy became obvious when the policies advocated by the Keynesians were implemented after the Second World War. But politics has triumphed over logic and we’ve forgotten all the crucial things he explained. That its teaching, translated into practice, was austere and often unpalatable, lent it virtue. Introduction to Keynesian Theory: Keynes was the first to develop a systematic theory of employment in his book. In other words, it is the highest rate of return over cost expected from producing one more unit (marginal unit) of a particular type of capital asset. It is the return of confidence, to speak in ordinary language, which is so insusceptible to control in an economy of individualistic capitalism. In 1937 he suffered a severe heart attack . In it, he argues vigorously for strong government action to correct the excesses of laissez-faire capitalism. As such it is called Consumption Function. Two years later, though not completely recovered, he returned to teaching at Cambridge, wrote three influential articles on war finance entitled How to Pay for the War (1940; later reprinted as Collected Writings , vol. The only thing that can save us is if “millionaires find their satisfaction in building mighty mansions to contain their bodies when alive and pyramids to shelter them after death, or, repenting of their sins, erect cathedrals and endow monasteries or foreign missions.” That’s no way to run a country. 100 + Rs. Perhaps the government should start buying and selling long-term bonds to address this. The General Theory of Employment, Interest and Money transformed economics and changed the face of modern macroeconomics. “It is in determining the volume, not the direction, of actual employment that the existing system has broken down.”. This dual approach to income determination has proved of great help in theoretical model building on the one side and national income accounting on the other. They are “undoubtedly in the right [at present],” when investment is “unplanned and uncontrolled.” There’s no other way to raise employment. The more virtuous we are, the more determinedly thrifty, the more obstinately orthodox in our national and personal finance, the more our incomes will have to fall when interest rises relatively to the marginal efficiency of capital. This website includes study notes, research papers, essays, articles and other allied information submitted by visitors like YOU. It’s also possible (although unlikely) that no one will believe the government can keep rates so low and so they begin hoarding all the new cash the government prints. The government lowers interest rates so that there’s full employment. Some of these are controllable by policy, others are not so. And there’s the issue that even at low rates of interest, banks still need to trust their borrowers and make enough to pay their expenses, which may require them to raise rates. A shorter account will be found in the article on Keynesian economics. But to assume that it actually does so is to assume our difficulties away. It means disserving or accumulated-wealth consumption. You use the extra people to get you up to speed, then you lay them off. [AS: This sounds pretty ridiculous, I know, but give it a minute.]. Keynes’s first proposition was that total income depends upon the volume of total employment, which depends upon effective demand (D), which in turn, depends upon consumption expenditure (D1) and investment expenditure (D2): therefore, Effective Demand D = D1 + D2. Not only is income equal to expenditure, Y = C +I, but saving also equals investment, S = I. During depression he would advocate a deficit budget to stimulate effective demand and in times of inflation, he wanted the government to have a surplus budget to restrict effective demand. “Consumption — to repeat the obvious — is the sole end and object of all economic activity.” What are we making things for if not to use them? There are other reasons people might want to hold cash. This raises the price, which makes Apple richer but doesn’t help any employees — and Apple likes to save its money much more than its employees do. Before we do so, it will help us to know the general framework or apparatus of Keynes’s theory. they are simply bartered away; Pigou’s definition was of no use. Practical men, who believe themselves to be quite exempt from any intellectual influences, are usually the slaves of some defunct economist. [AS: This is truly brilliant. (p.181), were inserted by Keynes himself. According to Prof. Hansen, Consumption Function is the most important contribution of J.M. The only solution would be to force everyone to either to buy goods or capital assets with everything they own. As I said, that’s the naive view — there are a couple complications. In other words, it shows that whatever people earn is being spent either on consumption or on investment. Net income is found by deducting supplementary costs V from the income (A-U). Estimates are at best estimates and they can at times differ from the actual. And with the disappearance of its rentier aspect much else in it besides will suffer a sea-change. Why is there a liquidity preference? As there is disequilibrium, income will have to rise. Keynes considered government as the sole supplier of money in the short period. It is better that a man should tyrannise over his bank balance than over his fellow-citizens; and whilst the former is sometimes denounced as being but a means to the latter, sometimes at least it is an alternative. Like “The difficulty lies, not in the new ideas, but in escaping from the old ones, which ramify, for those brought up as most of us have been, into every corner of our minds.” As income increases, consumption also increases but not so much as the increase in income. The C +I line lies parallel to and above C, the vertical distance between them showing investment For determining the equilibrium level of income we need the total expenditure (C + 7) line and the 45° line (Y= C+S). ], 7: Keynes spends the chapter defending his decision to define savings as equal to investment. Reading Keynes’ General Theory of Employment, Money, and Interest then is a sobering experience. Keynes, however, called it a social vice, as more saving on the part of an individual will mean less saving on the part of another individual, leaving the total savings of the community unaffected. Everyone builds houses thinking they’ll all sell for lots and lots, then they find they aren’t actually selling for so much and the economy collapses. Generally speaking, saving is done in the form of cash or in buying shares and stocks, bonds etc. Instead, saving lowers demand and thus decreases employment. | Keynes’s General Theory. As a result, the theory supports the expansionary fiscal policy. The straight line through the origin (Y = C + S) makes an angle of 45′ with the two axes. The result is that saving, which is income not spent on consumption, goes on increasing. But it’s not easy to think of useful things to make for the future. What changes how much they spend? Some industries hit “bottlenecks” first, causing their prices to rise and demand to be funneled into industries that are faster to respond. It tells us that there is a direct relation between income and consumption. In which case, “a decreased readiness to spend will be looked on in quite a different light.”, [AS: And so this is the famous paradox of thrift. The social object of skilled investment should be to defeat the dark forces of time and ignorance which envelop our future. 5: Businesses make production decisions not based on sales or anything solidly measurable, but on personal opinions: expectations. But if the ideas are correct — an hypothesis on which the author himself must necessarily base what he writes — it would be a mistake, I predict, to dispute their potency over a period of time. According to Keynes, this was the normal situation of a free-enterprise market economy and economists hailed this idea of Keynes as the most significant gift to economics. And the stock market depends on “what is, in truth, a convention” — namely that the current valuation of a company is an accurate assessment of its expected yield — that stock prices will only change if there’s new evidence suggesting the yield will be different. Consumption depends upon propensity to consume and investment is determined by inducement to invest. Generally these policies were successful in preventing heavy unemployment like that experienced during the days of the Great Depression. The bought and the un bought do not differ in kind from one another in any fundamental respect. However, it may be noted that the suitability of any particular definition depends upon the purpose for which it is to be used. … But there are many difficulties which Gesell did not face. Keynes, the story goes, figured out the causes of the Great Depression and in doing so revolutionized the field of economics. Nor is it necessary that anyone should keep his simple faith in the conventional basis of valuation having any genuine long-term validity. 750 at the end of the year having suffered a reduction in the value worth Rs. my shorter summary of the fundamental ideas, The General Theory of Employment, Interest and Money. But unfortunately they tended to give rise to the phenomenon known as ‘stop-go’. But we could increase investment: “the wisest course is to advance on both fronts at once.” Not just so that the people we give money to can buy the new products investment creates, but so that they have enough money to buy even more, and thus spark growth themselves! Thus, net income = A – U – V. In other words, both user costs (U) and supplementary costs (V) have to be subtracted from Gross National Product (A) to obtain the net national income. In his ‘General Theory’ Keynes used two approaches to the determination of income: Both these approaches lead to the determination of the same level of income. They got it in their head that they were going to build a railroad, and by Jove they did. He assumed that there is a fairly high degree of competition in the markets. For that may enable the so-called boom to last. That said, one wouldn’t want to get rid of money altogether: [D]angerous human proclivities can be canalised into comparatively harmless channels by the existence of opportunities for money-making and private wealth, which, if they cannot be satisfied in this way, may find their outlet in cruelty, the reckless pursuit of personal power and authority, and other forms of self-aggrandisement. Indeed, the basic model assumed that wages and prices are fixed as long as the government is reducing unemployment. And, if our theory does work and we end up with full employment, then we return to the world of the classical economic theory, whose only flaw was assuming that full employment was the only possible state of affairs. The Middle Ages built cathedrals and sang dirges. Most people think that as the interest rate goes up, spending goes down and saving goes up, but this shows that saving and spending both decrease. stimulus — in mind here, although he never really comes out and says it.] In The General Theory of Employment, Interest and Money, the British economist John Maynard Keynes argues that the belief that markets naturally tend towards full employment is a fallacy, and that state interventionism is therefore necessary to … But as interest rates get lower, it becomes profitable to invest in building things with smaller and smaller expected yields. Keynesians believe consumer demand is the primary driving force in an economy. Keynes disputed the classical assumption of automaticity of full employment and the classical prescription that in the event of an economic depression wage cuts would bring about full employment in the economy. The straight line labelled C shows the behaviour of consumption expenditure with respect to income. Therefore, Keynes called his treatise the General Theory There is no remedy but to persuade the public that green cheese is practically the same thing and to have a green cheese factory (i.e. money) is something which cannot be produced and the demand for which cannot be readily choked off. Before publishing your Articles on this site, please read the following pages: 1. We shall study, in a summary form, the main ideas of the theory. The higher the liquidity preference i.e., the desire of the people to hold cash, the higher the rate of interest which must be offered to overcome their liquidity preference. Keynesian demand management policies were used by the governments of most Western countries in the attempt to keep the unemployment levels down. (Keynes goes on to contrast gold-mining with building new houses which, being actually useful, has the side effect of decreasing the rent of old ones. Column 3 in the table shows that at the level of income of 50 crores, saving is negative, that is, minus 10 crores. Keynes believed that whenever an investment is made in an economy, the national income increases not only by the amount of investment, but by something much more than the original investment. The result is “a gradual crescendo in the level of employment, rising to a peak and then declining to the new long-period level.” This can happen even if you don’t expect to sell more things, but just a slightly different thing: you “overhire” to get up to speed on the new model, but then fire people until you’re back down to your previous level. Why is money so special? Thus decreased consumption leads to decreased employment. The public can’t control the amount of hoarding, since that’s necessarily equal to the amount of cash. And there are other problems: when the stock market crashes, rich people see themselves as less rich and decide to start spending less. It must have been due to a complex of suitabilities in the doctrine to the environment into which it was projected. THE GENERAL THEORY 2. Another is the amount you pay to employees and other companies and so on, the factor cost. Eventually, we’re forced to make things for today. These can be either short-term expectations (the barrista will be given the day off if management doesn’t expect any customers) or long-term expectations (Starbucks won’t open up a new story if they expect coffee consumption to start going down). In the post-war years his devotees bombarded me with copies of his works; yet, owing to certain palpable defects in the argument, I entirely failed to discover their merit. He observed that public works need to be undertaken only as long as private investment is deficient. In practical life the exact line of demarcation between investment and consumption is easily drawn; for example, expenditures on food and clothing are clearly consumption while those on buildings, factories and transportation facilities are easily investment. and everything will reach its marginal cost. Share Your PPT File, Is ‘General Theory’ a Depression Economics ? The horizontal axis of Figure 4.1 shows the levels of income and the vertical axis shows the levels of consumption, saving and investment in the economy. He did not draw any diagram in his ‘General Theory’ but his ideas can be better understood with the help of such a simple diagram as is given below. The point £ where the aggregate expenditure line intersects the 45° line shows that income is equal to total expenditure, Y= C + I. Indeed, this problem will be worse in richer countries, since the more people make the less of it they need to spend and thus less money is used to hire people. It is an inevitable result of an investment market whose organization encourages these behaviors. “We have all of us become used to finding ourselves sometimes on the one side of the moon and sometimes on the other, without knowing what route or journey connects them, related, apparently, after the fashion of our waking and our dreaming lives.” The right split is between the theory of the individual industry and the theory of the economy as a whole. Such costs have to be deducted from gross income to get net income on which the consumption of the community depends. There’s no math, but there’s still a lot to chew on. Its analysis remains comparatively static, though at times Keynes introduced expectations in his analysis. And the process of adjusting can have some odd effects: if you need to quickly ramp up production, you might keep hiring until you have more employees than you really need in the long-run. No, this is an overstatement. Thus we are so sensible, have schooled ourselves to so close a semblance of prudent financiers, taking careful thought before we add to the “financial” burdens of posterity by building them houses to live in, that we have no such easy escape from the sufferings of unemployment. It is because of this that Keynesians have put more faith in fiscal rather than monetary policy. It is interesting to notice that the characteristic which has been traditionally supposed to render gold especially suitable for use as the standard of value, namely, its inelasticity of supply, turns out to be precisely the characteristic which is at the bottom of the trouble. We’ll call these hours labor-units and we’ll call the money that gets paid for them wage-units. The General Theory of Employment, Interest and Money is a highly significant work that marked a turning point in the development of modern economic theory. Whilst, therefore, the enlargement of the functions of government, involved in the task of adjusting to one another the propensity to consume and the inducement to invest, would seem to a nineteenth-century publicist or to a contemporary American financier to be a terrific encroachment on individualism, I defend it, on the contrary, both as the only practicable means of avoiding the destruction of existing economic forms in their entirety and as the condition of the successful functioning of individual initiative. Firstly, it was clear that a laissez-faire capitalist economy will not be able to maintain full employment even if it is attained. And “it is not so easy to revive the marginal efficiency of capital, determined, as it is, by the uncontrollable and disobedient psychology of the business world. The measure of success attained by Wall Street, regarded as an institution of which the proper social purpose is to direct new investment into the most profitable channels in terms of future yield, cannot be claimed as one of the outstanding triumphs of laissez-faire capitalism — which is not surprising, if I am right in thinking that the best brains of Wall Street have been in fact directed towards a different object. He laid down the policy of starting public works financed from deficit financing through direct throw of additional currency or via credit creation. It’s hard to convey the excitement I felt when reading this.] Keynes uses some archaic language and is trying to communicate some complicated ideas. Disclaimer Copyright, Share Your Knowledge In 1987, Greenwald and Stiglitz accused Keynes’s summary of the "General Theory" in chapter 18 of relying upon “neoclassical and Marshallian tools.” Others say the problem is that the country is so unequal that poor people can’t spend enough. Investment is either foreign or domestic. These two combined are the prime cost. The same level of income gets determined whether we have the Y = C +I approach or the S=I approach. It’s only the second kind that’s an actual waste of resources, and the solution to it isn’t raising interest rates “which would probably deter some useful investments and might further diminish the propensity to consume, but in taking drastic steps, by redistributing incomes or otherwise, to stimulate the propensity to consume.”. We conclude by observing that the nature of economic problems of more developed economies has changed so much that Keynesian policies alone are not so much relevant. 100 crores consumption is also Rs. Table 4.1 is meant to illustrate the income expenditure approach to macro equilibrium. In fact, monetary unit (money) had been employed usually as the standard of measurement. Prices in Keynes’s model use only after full employment. They keep doing what they did yesterday unless they have a reason to change. And some of the money can “leak” out to other countries. Keynes's General Theory has been misunderstood as relying on frictions to justify the need for the visible hand of government to complement the invisible hand of the market. Share Your PDF File He gave practically useful policy. Of course there’s lots of different things you can invest in; we’re assuming that you do whatever maximizes your expected return. Instead, it might turn out “a somewhat comprehensive socialisation of investment will prove the only means of securing an approximation to full employment; though this need not exclude all manner of compromises and of devices by which public authority will co-operate with private initiative.” Still, this is a comparatively conservative claim: But beyond this no obvious case is made out for a system of State Socialism which would embrace most of the economic life of the community. All it can do is change the price of hoarding — the interest rate. A.C. Pigou has tried to limit down the concept so as to make it practicable. (So inflation might actually be a better solution than wage cuts.). But mercantilists saw the key points sooner than most, calling for an increase in money to reduce the interest rate. Investment also includes additions to stocks of manufactured and semi-manufactured goods (inventories) as well as in fixed capital. [AS: Marginal efficiency of capital comes up a lot, so we’ll save time by calling it “your expected return.”]. But the truth is exactly the opposite: “That the world after several millennia of steady individual saving, is so poor as it is in accumulated capital-assets, is to be explained, in my opinion, neither by the improvident propensities of mankind, nor even by the destruction of war, but by the high liquidity-premiums formerly attaching to the ownership of land and now attaching to money.”, 19: Now that we have the theory, we can return to the point we started with: reducing nominal wages is unhelpful. vi The Economics of Keynes: A New Guide to The General Theory 3. I am sure that the power of vested interests is vastly exaggerated compared with the gradual encroachment of ideas. And it would remain for separate decision on what scale and by what means it is right and reasonable to call on the living generation to restrict their consumption, so as to establish in course of time, a state of full investment for their successors. It forgets that there is no such thing as liquidity of investment for the community as a whole. … Nor was there over-investment in the sense that the standard and equipment of housing was so high that everyone, assuming full employment, had all he wanted at a rate which would no more than cover the replacement cost, without any allowance for interest, over the life of the house; and that transport, public services and agricultural improvement had been carried to a point where further additions could not reasonably be expected to yield even their replacement cost. Yet he has scarcely established an equal claim to rank — a private, perhaps, but not a major in the brave army of heretics — with Mandeville, Malthus, Gesell and Hobson, who, following their intuitions, have preferred to see the truth obscurely and imperfectly rather than to maintain error, reached indeed with clearness and consistency and by easy logic, but on hypotheses inappropriate to the facts. But there’s two kinds of overinvestment: disappointing investments, where the investment would have made sense except the economy collapsed, and genuine overinvestment, where the investment could never have made money. Therefore, he made the specific assumption of short-period so as to concentrate on the problem at hand. For it now seems clear that the disquisitions of the schoolmen were directed towards the elucidation of a formula which should allow the schedule of the marginal efficiency of capital to be high, whilst using rule and custom and the moral law to keep down the rate of interest.” After all, “individual savings may be absorbed either by investment or by debts, and that there is no security that they will find an outlet in the former.” Laws against usury help ensure they do. Keynes: Long-term Expectations (Ch. 9: How does raising interest rates affect consumption? It is judged from the total expenditure in the economy. But this means that as national income increases, a smaller proportion of it will get spent, so more of it will have to be invested. Saving money for the future is not the same as making things for the future — it’s only the latter that’s useful. This is because people spend on consumption to the extent of Rs. 12 of Interest Rate Theory) Page 1 John Maynard Keynes The General Theory of Employment, Interest and Money Chapter 12. It would be the end of the rentier — the rich person who grows richer by using his wealth to exploiting others. Keynes begins the General Theory with a summary of the classical theory of employment, which he encapsulates in his formulation of Say's Law as the dictum "Supply creates its own demand". are on the right track. Keynes does not deduct the whole of depreciation from the Gross National Product, he subtracts a little less than the whole amount of depreciation called ‘User Cost’. The distinction between consumption and investment is fundamental to Keynes’ General Theory. … The insights here have yet to be fully mined.”]. Why should it be any different from a futures contract on wheat? For there would obviously be a natural tendency towards the optimum employment of resources in a society which was functioning after the manner of the classical postulates. Are the interests which they will thwart stronger and more obvious than those which they will serve? Therefore, point E shows equilibrium in the economy. But although the doctrine itself has remained unquestioned by orthodox economists up to a late date, its signal failure for purposes of scientific prediction has greatly impaired, in the course of time, the prestige of its practitioners. Such public investment, he said, best achieves the multiplier effects. The economics of Keynes 's book contain amplifications of various amounts of consumption expenditure that consumers incur.
