An alternative definition, which amounts, however, to the same thing, will be given in the next chapter (p. 26 below). The division of Economics between the Theory of Value and Distribution on the one hand and the Theory of Money on the other hand is, I think, a false division. Sie könnten die Produktion kurzfristig erhöhen. I think, on two fundamental postulates, though practically without discussion, namely: That is to say, the wage of an employed person is equal to the value which would be lost if employment were to be reduced by one unit (after deducting any other costs which this reduction of output would avoid); subject, however, to the qualification that the equality may be disturbed, in accordance with certain principles, if competition and markets are imperfect. The following passage from Marshall’s Pure Theory of Domestic Values[9] illustrates the traditional approach: The whole of a man’s income is expended in the purchase of services and of commodities. This is in the Ricardian tradition. If we assume a sufficient interval for the quantity of equipment itself to change, the elasticities of supply will be decidedly greater eventually. The Marshall of the Principles had become sufficiently doubtful to be very cautious and evasive. The classical postulates do not admit of the possibility of the third category, which I shall define below as ‘involuntary’ unemployment. For a realistic interpretation of it legitimately allows for various inexactnesses of adjustment which stand in the way of continuous full employment: for example, unemployment due to a temporary want of balance between the relative quantities of specialised resources as a result of miscalculation or intermittent demand; or to time-lags consequent on unforeseen changes; or to the fact that the change-over from one employment to another cannot be effected without a certain delay, so that there will always exist in a non-static society a proportion of resources unemployed ‘between jobs’. His whole theory is centered around boosting aggregate demand so that capitalists will maximize investment. Indeed it is strange that so little attempt should have been made to prove or to refute it. This is a question for historical generalisation rather than for pure theory. Moreover, it is only in highly exceptional circumstances that an increase in the quantity of money will be associated with a decrease in the quantity of effective demand. Something similar is required today in economics. This is the nature of economic thinking. The General Theory’s messy text was converted into a simple model that soon became a staple of introductory economics textbooks. But, whether logical or illogical, experience shows that this is how labour in fact behaves. Thus increasing output will be associated with rising prices, apart from any change in the wage-unit. If this is the case, such unemployment, though apparently involuntary, is not strictly so, and ought to be included under the above category of ‘voluntary’ unemployment due to the effects of collective bargaining, etc. At different points in this chapter we have made the classical theory to depend in succession on the assumptions: (1) that the real wage is equal to the marginal disutility of the existing employment; (2) that there is no such thing as involuntary unemployment in the strict sense; (3) that supply creates its own demand in the sense that the aggregate demand price is equal to the aggregate supply price for all levels of output and employment. John Maynard Keynes Originaltitel The General Theory of Employment, Interest and Money (Englisch, 1936) Die Allgemeine Theorie der Beschäftigung, des Zinses und des Geldes wurde von dem britischen Ökonomen John Maynard Keynes verfasst. 10 General Theory, pp. The principal objective factors which influence the propensity to consume appear to be the following: (1) A change in the wage-unit. The general price-level depends partly on the rate of remuneration of the factors of production which enter into marginal cost and partly on the scale of output as a whole, i.e. There is no reason to modify this conclusion when we pass to industry as a whole. For there may be no method available to labour as a whole whereby it can bring the general level of money-wages into conformity with the marginal disutility of the current volume of employment. Or we can pass from this simplified propaedeutic to the problems of the real world in which our previous expectations are liable to disappointment and expectations concerning the future affect what we do to-day. Keynes asserted that rentiers held some notion of a normal rate of interest. Das Buch ist, wie Keynes schreibt, das Ergebnis eines langen Kampfes, aus den alten Denkmustern auszubrechen. But, apart from this, the conclusion that the costs of output are always covered in the aggregate by the sale-proceeds resulting from demand, has great plausibility, because it is difficult to distinguish it from another, similar-looking proposition which is indubitable, namely that income derived in the aggregate by all the elements in the community concerned in a productive activity necessarily has a value exactly equal to the value of the output. If the total demand for goods at full employment is less than the total output, then the economy has to contract until equality is achieved. Now ordinary experience tells us, beyond doubt, that a situation where labour stipulates (within limits) for a money-wage rather than a real wage, so far from being a mere possibility, is the normal case. But the “income-velocity of money” is, in itself, merely a name which explains nothing. The acuteness and the peculiarity of our contemporary problem arises, therefore, out of the possibility that the average rate of interest which will allow a reasonable average level of employment is one so unacceptable to wealth-owners that it cannot be readily established merely by manipulating the quantity of money. John Maynard Keynes, (born June 5, 1883, Cambridge, Cambridgeshire, England—died April 21, 1946, Firle, Sussex), English economist, journalist, and financier, best known for his economic theories (Keynesian economics) on the causes of prolonged unemployment. : "Worldly wisdom teaches that it is better for reputation to fail conventionally than to succeed unconventionally." Keynes was a British economist who died just after the last war. Any other way of applying our formal principles of thought (without which, however, we shall be lost in the wood) will lead us into error. I do not myself attach much value to manipulations of this kind; and I would repeat the warning, which I have given above, that they involve just as much tacit assumption as to what variables are taken as independent (partial differentials being ignored throughout) as does ordinary discourse, whilst I doubt if they carry us any further than ordinary discourse can. But in the long run is there not some simpler relationship? Thus as output increases, a series of “bottlenecks” will be successively reached, where the supply of particular commodities ceases to be elastic and their prices have to rise to whatever level is necessary to divert demand into other directions. 117 and 120-21. Manche seiner Kapitel sind schwierig und mühsam zu lesen. Therefore, after the Paris Commune, it was replaced by another with the so called mid-19thcentury idea of “marginal revolution”. (3) Since resources are not interchangeable, some commodities will reach a condition of inelastic supply whilst there are still unemployed resources available for the production of other commodities. It is, however, worth pointing out that, of the four terms ed, ew, ee and eo upon which the effect on prices of changes in the quantity of money depends, ed stands for the liquidity factors which determine the demand for money in each situation, ew for the labour factors (or, more strictly, the factors entering into prime-cost) which determine the extent to which money-wages are raised as employment increases, and ee and eo for the physical factors which determine the rate of decreasing returns as more employment is applied to the existing equipment. Nor, of course, is this list of possible interactions complete. A fall in real wages due to a rise in prices, with money-wages unaltered, does not, as a rule, cause the supply of available labour on offer at the current wage to fall below the amount actually employed prior to the rise of prices. Sometimes the wage-unit, but more often the monetary standard or the monetary system (in particular through the development of bank-money), would be adjusted so as to ensure that the quantity of money in terms of wage-units was sufficient to satisfy normal liquidity-preference at rates of interest which were seldom much below the standard rates indicated above. The attempt to elucidate this problem will be one of our main themes. An eight-hour day does not constitute unemployment because it is not beyond human capacity to work ten hours. The most important theoretical feature of this new paradigm was that it was supposedly bas… John Maynard Keynes This will be our contention. It is not very plausible to assert that unemployment in the United States in 1932 was due either to labour obstinately refusing to accept a reduction of money-wages or to its obstinately demanding a real wage beyond what the productivity of the economic machine was capable of furnishing. [1], The question, also, of the volume of the available resources, in the sense of the size of the employable population, the extent of natural wealth and the accumulated capital equipment, has often been treated descriptively. Thus the employment of an additional man will, if it occurs, necessarily involve a transfer of income from those previously in work to the entrepreneurs. But if the wage of a given grade of labourers is uniform irrespective of the efficiency of the individuals, we shall have rising labour-costs, irrespective of the efficiency of the equipment. [11] Post-war economists seldom, indeed, succeed in maintaining this standpoint consistently; for their thought today is too much permeated with the contrary tendency and with facts of experience too obviously inconsistent with their former view. Output in either case will be unaltered. The right dichotomy is, I suggest, between the Theory of the Individual Industry or Firm and of the rewards and the distribution between different uses of a given quantity of resources on the one hand, and the Theory of Output and Employment as a whole on the other hand. That is to say, the real wage of an employed person is that which is just sufficient (in the estimation of the employed persons themselves) to induce the volume of labour actually employed to be forthcoming; subject to the qualification that the equality for each individual unit of labour may be disturbed by combination between employable units analogous to the imperfections of competition which qualify the first postulate. John Maynard Keynes, 1st Baron Keynes CB FBA (/ keɪnz / KAYNZ; 5 June 1883 – 21 April 1946), was an English economist, whose ideas fundamentally changed the theory and practice of macroeconomics and the economic policies of governments. In emphasising our point of departure from the classical system, we must not overlook an important point of agreement. It means that, with a given organisation, equipment and technique, real wages and the volume of output (and hence of employment) are uniquely correlated, so that, in general, an increase in employment can only occur to the accompaniment of a decline in the rate of real wages. These points of discontinuity are determined by the psychology of the workers and by the policies of employers and trade unions. 7 J. M. Keynes, The General Theory of Employment, Interest andMoney, London, 1936, p. 32. 11. (5) The remunerations of the factors entering into marginal cost will not all change in the same proportion. If, in conditions of tolerable average employment, this net yield turns out to be infinitesimal, time-honoured methods may prove unavailing. 8. The average level of employment was, of course, substantially below full employment, but not so intolerably below it as to provoke revolutionary changes. This, to the best of my understanding, is the stance of Professor Pigou’s Theory of Unemployment — the only detailed account of the classical theory of employment which exists.[3]. John Maynard Keynes ist die Person hinter dieser Konjunkturtheorie. But as soon as we pass to the problem of what determines output and employment as a whole, we require the complete theory of a Monetary Economy. Having, however, satisfied tradition by introducing a sufficient number of simplifying assumptions to enable us to enunciate a Quantity Theory of Money, let us now consider the possible complications which will in fact influence events: (1) Effective demand will not change in exact proportion to the quantity of money. Too large a proportion of recent “mathematical” economics are mere concoctions, as imprecise as the initial assumptions they rest on, which allow the author to lose sight of the complexities and interdependencies of the real world in a maze of pretentious and unhelpful symbols. When a further increase in the quantity of effective demand produces no further increase in output and entirely spends itself on an increase in the cost-unit fully proportionate to the increase in effective demand, we have reached a condition which might be appropriately designated as one of true inflation. It is true that, when we pass to output as a whole, the costs of production in any industry partly depend on the output of other industries. Subject to these qualifications, the volume of employed resources is duly determined, according to the classical theory, by the two postulates. If this is true, the wage-goods equivalent of the existing money-wage is not an accurate indication of the marginal disutility of labour, and the second postulate does not hold good. 2,2 Millionen Menschen auf die Höhe des Sozialhilfesatzes herunter. In this case we have constant returns and a rigid wage-unit, so long as there is any unemployment. Die Nachfrage restringiert das Angebot. So far, we have been primarily concerned with the way in which changes in the quantity of money affect prices in the short period. (3) Under (2) we have been contemplating the possibility of supply being imperfectly elastic. Chapter 13. 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. 11 How revealing is Keynes' attitude in this context: He treated Das Kapital … 2. They are supposed to be equally applicable to a closed system as to an open system, and are not dependent on the characteristics of an open system or on the effects of a reduction of money-wages in a single country on its foreign trade, which lie, of course, entirely outside the field of this discussion. In addition to ‘frictional’ unemployment, the postulate is also compatible with ‘voluntary’ unemployment due to the refusal or inability of a unit of labour, as a result of legislation or social practices or of combination for collective bargaining or of slow response to change or of mere human obstinacy, to accept a reward corresponding to the value of the product attributable to its marginal productivity. To-day and presumably for the future the schedule of the marginal efficiency of capital is, for a variety of reasons, much lower than it was in the nineteenth century. If this is not true, then there is no longer any reason to expect a tendency towards equality between the real wage and the marginal disutility of labour. He wrote a number of widely-read books on economic and political matters and held various government posts. [5] They do not seem to have realised that, unless the supply of labour is a function of real wages alone, their supply curve for labour will shift bodily with every movement of prices. But the other, more fundamental, objection, which we shall develop in the ensuing chapters, flows from our disputing the assumption that the general level of real wages is directly determined by the character of the wage bargain. above the lowest.

For every discussion concerning fluctuations of employment, of which there have been many, has been concerned with it.
