In 1936, in the midst of the Great Depression, John Maynard Keynes forever transformed the field of macroeconomics with this classic and still controversial work. 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. If there are people around willing to work, jobs will spring up to make use of them. Keynes considered government as the sole supplier of money in the short period.

Call that the yield. So how does printing money affect prices? Or perhaps between the stationary economy and the shifting one, for money’s power “flows from its being a link between the present and the future.”. “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. There’s an asymmetry in the system that workers will resist falling wages, but not rising ones. So the government will print money to keep the interest rate at a level corresponding to full employment. Moreover, this behavior is not the outcome of a wrong‐headed propensity. And, in practice, people don’t calculate their expectations from scratch each morning. The main problem with the Keynesian model was that it was meant for the short run. I am sure that the power of vested interests is vastly exaggerated compared with the gradual encroachment of ideas. But it’s not easy to think of useful things to make for the future. — III. It would be absurd to assert of the United States in 1929 the existence of over-investment in the strict sense. Sorry.] Perhaps the government should start buying and selling long-term bonds to address this. Marginal efficiency of capital refers to the expected profitability of an additional capital asset; it may be defined as the highest rate of return over cost accruing from an additional unit of a capital asset. Thus gold-mines are of the greatest value and importance to civilisation. What happens isn’t so much excessive investment as misdirected investment. 9: How does raising interest rates affect consumption? The owner of capital can obtain interest because capital is scarce, just as the owner of land can obtain rent because land is scarce. 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. […]. 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. 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. Therefore, Keynes called his treatise the General Theory 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. Simple Income Determination 7. But if effective demand is adequate, average skill and average good fortune will be enough. Thus the government must step in. So we’ll use only two types of counts: those of actual currency (money-values) and those of people (employment). Madmen in authority, who hear voices in the air, are distilling their frenzy from some academic scribbler of a few years back. It tells us that there is a direct relation between income and consumption. Let us presume (with Keynes) that the level of investment is not related to income. Investment is either foreign or domestic. Content Guidelines 2. 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. Is the fulfilment of these ideas a visionary hope? Marginal prime costs and labor costs increase as industry is forced to use more expensive equipment and laborers, resulting in higher prices. Keynes’ concept of national income lies somewhat between the Gross National Product and the Net National Product. Quite the contrary. 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. Keynes uses some archaic language and is trying to communicate some complicated ideas. Money can’t survive on its own. 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 points on this line fulfill the equilibrium condition in the economy: i.e. 2 likes. Keynes has found a crack in the classical theory. 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. Absence of Governmental Part in Economic Activity: The government is assumed to play no (significant) part either as a taxer or as a spender. His theory of interest depends upon it. But this clearly isn’t true — people can save money under their mattress and not get any interest. Keynes seems to suggest this can be modeled as “a rapid liability to change in the supply of labor;” I guess that’s possible. As is often the case with imperfectly analysed intuitions, their significance only became apparent after I had reached my own conclusions in my own way. “I was brought up to believe that the attitude of the Medieval Church to the rate of interest was inherently absurd, and that the subtle discussions aimed at distinguishing the return on money-loans from the return to active investment were merely Jesuitical attempts to find a practical escape from a foolish theory. What about recovery? 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. 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. In Summary: What is the difference between Hayek and Keynes? … No explanation of this is provided by the Keynesian Theory. 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. As I said, that’s the naive view — there are a couple complications. For the book is, indeed, truly brilliant, a definite work of genius. The more open our stock markets get, the more speculators predominate, and the worse things get for us. “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.”. The public can’t control the amount of hoarding, since that’s necessarily equal to the amount of cash. The social object of skilled investment should be to defeat the dark forces of time and ignorance which envelop our future. 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. In it, he argues vigorously for strong government action to correct the excesses of laissez-faire capitalism. And there are some, I believe, who practise the fourth, fifth and higher degrees. Earlier definitions did not throw any light on the factors which go to determine income or its relation with employment; this purpose was amply achieved in the definition adopted by Keynes. Reading Keynes’ General Theory of Employment, Money, and Interest then is a sobering experience. But whilst there may be intrinsic reasons for the scarcity of land, there are no intrinsic reasons for the scarcity of capital. And even if they were willing to wait, why should they trust you? In the Keynesian model, a change in money supply only affects national income through its effect on the rate of interest. If this happens, then it seems likely that within a generation expected return will reach zero [AS: !!] But this is good, because otherwise wages would fall to zero in any downturn and the entire economy would shut down. Generally speaking, saving is done in the form of cash or in buying shares and stocks, bonds etc. He wanted to know the considerations that weigh with entrepreneurs when they decide to employ certain number of men. 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). In his view, short period is that in which new investments do not change the technique, the organisation and equipment. Further as income rises, saving also rises. Fleshing out the GT with tools not available to Keynes, Marglin exposes the fundamental failure of markets to self-regulate and draws lessons for fiscal and monetary policies. This incredible work of economic thought described the division of labor and the invisible hand in 1705, a full seventy years before Adam Smith. It is not the ownership of the instruments of production which it is important for the State to assume. 4. Thus, after all, the actual rates of aggregate saving and spending do not depend on Precaution, Foresight, Calculation, Improvement, Independence, Enterprise, Pride or Avarice. It may turn out that the propensity to consume will be so easily strengthened by the effects of a falling rate of interest, that full employment can be reached with a rate of accumulation little greater than at present.
