And getting money for it is much harder — people don’t like it when you tell them “Yes, the stocks you bought are worthless now but just wait! Since few of the readers of this book are likely to be well acquainted with the significance of Gesell, I will give to him what would be otherwise a disproportionate space. If that’s true, even wasting money is a good thing. Long-term expectations can’t be easily checked, so when they do change, they often change suddenly. Domestic investment is encouraged by the interest rate and foreign investment by the balance of trade. If this happens, then it seems likely that within a generation expected return will reach zero [AS: !!] The celebrated optimism of traditional economic theory, which has led to economists being looked upon as Candides, who, having left this world for the cultivation of their gardens, teach that all is for the best in the best of all possible worlds provided we will let well alone, is also to be traced, I think, to their having neglected to take account of the drag on prosperity which can be exercised by an insufficiency of effective demand. The problem is that capitalists aren’t buying capital per se, they’re buying an expected yield. In general, if more people are working then more stuff is getting made, although this obviously isn’t a perfect connection. In olden days, what happened was that rough-riding men of business thought taking risks was manly and invested their money as a way of life. Eventually, we’re forced to make things for today. Back to the future: a heterodox economist rewrites Keynes’s General Theory of Employment, Interest, and Money to serve as the basis for a macroeconomics for the twenty-first century.. John Maynard Keynes’s General Theory of Employment, Interest, and Money was the most influential economic idea of the twentieth century. It seems difficult to explain the high unemployment of the Great Depression this way, but economists didn’t see how it could be otherwise. Keynes book was published post-Great Depression period. They are “undoubtedly in the right [at present],” when investment is “unplanned and uncontrolled.” There’s no other way to raise employment. The actual, private object of the most skilled investment to-day is âto beat the gunâ, as the Americans so well express it, to outwit the crowd, and to pass the bad, or depreciating, half-crown to the other fellow. Well, until you have full employment obviously. Keynes's theory of the determination of equilibrium real GDP, employment, and prices focuses on the relationship between aggregate income and expenditure. Assumptions 4. A brief summary of the theory of employment to be worked out in the course of the following chapters may, perhaps, help the reader at this stage, even though it may not be fully intelligible. There are all sorts of practical problems with lowering interest below zero, so instead what happens is that, in laissez-faire, employment falls to reach the new low levels. The classical school — including Keynes in earlier years — grew up mocking mercantilism (protectionism) as incoherent and absurd. According to him, an increase in the aggregate effective demand would increase the level of employment and vice-versa. But this simplification, with which we shall dispense later, is introduced solely to facilitate the exposition. “There are advantages in some degree of flexibility in the wages of particular industries so as to expedite transfers from those which are relatively declining to those which are relatively expanding. For professional economists, after Malthus, were apparently unmoved by the lack of correspondence between the results of their theory and the facts of observation;—a discrepancy which the ordinary man has not failed to observe, with the result of his growing unwillingness to accord to economists that measure of respect which he gives to other groups of scientists whose theoretical results are confirmed by observation when they are applied to the facts. Keynes economic theory was developed by a British Economist John Maynard Keynes, which explains the cause of less than full employment and role of government or activist Policies to stabilize the economy at equilibrium at or near full-employment with acceptable expected inflation. But this doesn’t effect the long-term rates, which depend on people’s expectations of what the government will do to short-term rates. No, the interest rate is the “price” people demand for parting with their cash. Therefore the aggregate supply price varies according to different number of workers employed. Keynesian Theory of Income and Employment: Definition and Explanation: John Maynard Keynes was the main critic of the classical macro economics. Introduction to Keynesian Theory: Keynes was the first to develop […] [emphasis added], 11: Imagine you get a new widget-making machine. Moreover, effective demand refers to the total expenditure of an economy at a particular employment level. Keynes used his income‐expenditure model to argue that the economy's equilibrium level of output or real … The total expenditure is equal to the national income, which is equivalent to the national output. It’s difficult to get people to realize that investing money doesn’t actually lead to an increase in investments. But the classical school ignored the problem, as a consequence of introducing into their premisses conditions which involved its non-existence; with the result of creating a cleavage between the conclusions of economic theory and those of common sense. Keynesian economics was founded by economist John Maynard Keynes. But mercantilists saw the key points sooner than most, calling for an increase in money to reduce the interest rate. Keynes ignores long-run problem: Keynes assumes that ASF is given. We have to accept them as an inevitable result of applying to the conduct of the State the maxims which are best calculated to âenrichâ an individual by enabling him to pile up claims to enjoyment which he does not intend to exercise at any definite time. Keynes, however, got personally involved in only a few of them. [â¦]. At this point, aggregate demand and aggregate supply curve intersect each other. At this point, expected return might be just enough to cover the costs of production, plus a little for risk and skill — just like other goods. stimulus — in mind here, although he never really comes out and says it.] Since it seemed unlikely that society had run out of money-making jobs, it was assumed that unemployment was caused either by people not knowing where the jobs were (frictional unemployment) or insisting on being paid more than they could make (voluntary unemployment). Introduction to Keynesian Theory 2. It is not the ownership of the instruments of production which it is important for the State to assume. You might think (as Keynes once did) that the best solution is to just force people to hold on to what they buy, so they have to figure out what it’s really worth beforehand, but this will just push people to hold on to their money. Except during the war, I doubt if we have any recent experience of a boom so strong that it led to full employment. (So inflation might actually be a better solution than wage cuts.). The owner of capital can obtain interest because capital is scarce, just as the owner of land can obtain rent because land is scarce. This battle of wits to anticipate the basis of conventional valuation a few months hence, rather than the prospective yield of an investment over a long term of years, does not even require gulls amongst the public to feed the maws of the professional; â it can be played by professionals amongst themselves. It’s through the expected yield that changes in the value of money affect output. Have they insufficient roots in the motives which govern the evolution of political society? Even if you hire people for investment, the money those people get paid in turn gets spent on additional consumption, increasing employment indirectly as well. Some industries hit “bottlenecks” first, causing their prices to rise and demand to be funneled into industries that are faster to respond. But as interest rates get lower, it becomes profitable to invest in building things with smaller and smaller expected yields. Investment is just the amount of current output that isn’t consumed. Perhaps this is why it has a reputation for being a very tough book — so difficult that even economists can’t follow it. There’s the value of the widgets you expect [AS: there’s that word again] it to produce, less the cost of its inputs and maintenance. But if you’ve been unemployed long enough, you might actually want to work. This means that the expected sales receipts increase with an increase in the number of workers. You use the extra people to get you up to speed, then you lay them off. In the short run, he assumed that the factors of production, such as capital goods, supply of labor, technology, and efficiency of labor, remain unchanged while determining the level of employment. Keynes, the story goes, figured out the causes of the Great Depression and in doing so revolutionized the field of economics. But if the ideas are correct â an hypothesis on which the author himself must necessarily base what he writes â it would be a mistake, I predict, to dispute their potency over a period of time. Thus, higher the price required to induce the different quantities of employment, greater the level of employment would be. There’s no math, but there’s still a lot to chew on. 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. In John Maynard Keynes: the Economist as Savior, 1920-1936, Skidelsky -- in sometimes daunting detail -- took the reader up to the creation and publication of Keynes's magnum opus, The General Theory of Employment,Interest and Money. In particular, he was unaware that money was not unique” — if people didn’t hoard it, there’s lots of other things they could hoard. 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. But if effective demand is adequate, average skill and average good fortune will be enough. Thus, the slope of aggregate demand curve would be upward to the right. At some point we just need to consume more stuff.

Keynes seems to suggest this can be modeled as “a rapid liability to change in the supply of labor;” I guess that’s possible. 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 â 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. 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 have addressed the first, but what are its implications of the second? So stock traders don’t sit down and try to calculate the long-term expected yield; they try to guess the short-term change in the stock price and trade base on that. If we don’t ever spend it, it becomes worthless. Recall that the classical theory said people needed to be paid enough to compensate them for their distaste for working. When the capital development of a country becomes a by-product of the activities of a casino, the job is likely to be ill-done. And obviously you’ll keep borrowing money and investing it until your expected return reaches the market rate of interest. Another is the amount you pay to employees and other companies and so on, the factor cost. Therefore, Keynes theory of employment is also known as theory of employment determination and theory of income determination. But how much they sell is exactly dependent on how much people spend. Keynes has found a crack in the classical theory. The aggregate demand price exceeds the aggregate supply price or vice versa at some levels of employment. 10: We’ve established that an increase in investment leads to an increase in income. Second, if wages go down, then the cost of making things goes down, which means that prices go down, which means that in real terms wages end up staying about the same. “A full explanation is complex and must wait for Chapter 15.” But we can see one reason now: uncertainty about the expected [AS: there’s that word again] rate of interest. It would need a volume of a different character from this one to indicate even in outline the practical measures in which they might be gradually clothed. But these all depend on other complicating factors. “The fundamental psychological law,” he says, is that, on average, the amount people spend increases as the amount they make increases, but not as quickly. And there are other problems: when the stock market crashes, rich people see themselves as less rich and decide to start spending less. The more open our stock markets get, the more speculators predominate, and the worse things get for us. Interest today rewards no genuine sacrifice, any more than does the rent of land. The second half is filling it in. As per Keynes theory of employment, effective demand signifies the money spent on the consumption of goods and services and on investment. But calculating expected yields is much harder than guessing what everyone else will do; there’s no reason to think spending the same amount of time doing that is any more profitable. So I thought I’d try my best at an explanation/summary. OK, so you promote investment, but how much investment? One is the amount of capital and equipment and so on you use up, which we’ll call the user cost. Keynes’ theory of employment is a demand-deficient theory. Now, though this state of affairs would be quite compatible with some measure of individualism, yet it would mean the euthanasia of the rentier, and, consequently, the euthanasia of the cumulative oppressive power of the capitalist to exploit the scarcity-value of capital. Again we have a tradeoff between having a market (and thus volatility) or no market (and thus overcaution). Therefore, the gap between the income and consumption rate should be reduced by increasing the number of investment opportunities. And there must be a similar employment multiplier (k’) where for each person hired for a job, k’ people get hired in total. As problematic as this is, Keynes points out that it’s a lot more realistic than the classical theory, which just seems to magically assume everyone is paid in proportion to their productivity. The basic difference between the aggregate supply price and aggregate demand price should be analyzed carefully as both of them seem to be same. The classical view is that we are kept poor by our impatience — we insist on spending money now instead of saving it for later, when it will grow into more. The bearing of the foregoing theory on the first of these is obvious (Keynes, 1936, p. 372). (Since running a trade deficit with a country means sending them your precious metals instead of your exports.) Let us study these two concepts in detail. For that may enable the so-called boom to last. But I now read these discussions as an honest intellectual effort to keep separate what the classical theory has inextricably confused together, namely, the rate of interest and the marginal efficiency of capital. And with the disappearance of its rentier aspect much else in it besides will suffer a sea-change. 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. The main point related to starting point of Keynes theory of employment is the principle of effective demand. That is, if management decides to pay people $4 an hour instead of $5, people might go on strike, but nobody ever goes on strike demanding a raise because the cost of milk has gone up. â¦ The insights here have yet to be fully mined.”]. But we have shown that the extent of effective saving is necessarily determined by the scale of investment and that the scale of investment is promoted by a low rate of interest, provided t… It is the total amount of money paid by organizations to the different factors of production involved in the production of output. But you can’t jump-start it just by lowering interest rates, since the real problem is expected return. However, the individual demand curve slopes downward. 23: Now that Keynes has outlined his revolutionary theory, it’s time to look back at other economists the classical school dismissed. Thus the interest rate depends on people’s desire to hoard cash — their liquidity preference (L) — and the quantity of money (M). The total expenditure is equal to the national income, which is equivalent to the national output. Two pyramids, two masses for the dead, are twice as good as one; but not so two railways from London to York. Which is why the suggestion of making it spoil (by printing money with expiration dates, etc.) 20: We’ve said that employment ultimately comes from demand. (The details of how the remainder gets invested has to do with interest and will be addressed later.). The first half of this book will be dedicated to prying it open. Thus gold-mines are of the greatest value and importance to civilisation. The General Theory of Employment, Interest and Money was written by the English economist John Maynard Keynes.The book, generally considered to be his magnum opus, is largely credited with creating the terminology and shape of modern macroeconomics.Published in February 1936, it sought to bring about a revolution, commonly referred to as the "Keynesian Revolution", in the … And yet, the book is a necessary now as it was then: economics has not learned a single one of his lessons. But the money-wage level as a whole should be maintained as stable as possible, at any rate in the short period.”. Therefore, according to Keynes, level of employment is dependent on national income and output. This is the level of underemployment equilibrium, according to Keynes. I see, therefore, the rentier aspect of capitalism as a transitional phase which will disappear when it has done its work. But the side effect is that “the very long-run course of prices has almost always been upward.”. Reading Keynes’ General Theory of Employment, Money, and Interest then is a sobering experience. 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 â a proposition not without meaning and not without interest, but unsuitable as material for the differential calculus. Presumably this means that interest rates will become very low (although you don’t want them so low that nobody’s making things to sell today). Thus we are so sensible, have schooled ourselves to so close a semblance of prudent financiers, taking careful thought before we add to the âfinancialâ burdens of posterity by building them houses to live in, that we have no such easy escape from the sufferings of unemployment. If an organization does not get an adequate price so that cost of production is covered, then it employs less number of workers. (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. Thus we might aim in practice (there being nothing in this which is unattainable) at an increase in the volume of capital until it ceases to be scarce, so that the functionless investor will no longer receive a bonus; and at a scheme of direct taxation which allows the intelligence and determination and executive skill of the financier, the entrepreneur et hoc genus omen (who are certainly so fond of their craft that their labour could be obtained much cheaper than at present), to be harnessed to the service of the community on reasonable terms of reward. â¦ But there are many difficulties which Gesell did not face. 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. 24: The two great economic problems are unemployment and inequality. Aggregate demand price is different from demand for products of individual organizations and industries. There is a widespread tendency to portray Keynes as the founding father of the Welfare State and to claim that the Keynesian revolution provided the justification for the need of a large public sector in the economy. 14: “Certainly the ordinary man â banker, civil servant or politician â brought up on the traditional theory, and the trained economist also, has carried away with him the idea that whenever an individual performs an act of saving he has done something which automatically brings down the rate of interest â¦ without the necessity for any special intervention or grandmotherly care on the part of the monetary authority.”, But we’ve seen they’re quite wrong. But spending can have negative effects as well. [Tyler Cowen: “This is the best chapter in the book and one of the most important economics essays of all time. That meant … John Maynard Keynes,The General Theory (BN Publishing, 2008), pp. The effective demand can be expressed as follows: Effective demand = National Income = National Output. In the short run, he assumed that the factors of production, such as capital goods, supply of labor, technology, and efficiency of labor, remain unchanged while determining the level of employment. [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. However, after a certain level, the increase in employment level would not show an increase in the amount of sales receipts. 21: Traditional economics is divided between the theory of value (perfect competition, supply and demand, and all that good stuff) in the main spot and then over to the side has a separate theory of money (dealing interest rates and inflation), with no clear connection between the two. Some conservative economists have forgotten or ignored his work, but society as a whole remembers his basic discovery: you get out of downturns by spending money. Instead, saving lowers demand and thus decreases employment. 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.
