But this clearly isn’t true — people can save money under their mattress and not get any interest. 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. 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. But the actual course of events is more complicated still. 180 crores equals planned investment. (The details of how the remainder gets invested has to do with interest and will be addressed later.). The General Theory of Employment, Interest and Money [full text]. A hefty tax on each trade might be the best way to discourage speculation and thus improve the functioning of the market. 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. There’s an asymmetry in the system that workers will resist falling wages, but not rising ones. (Tyler Cowen, in his critical comments on the General Theory is struck by a throw-off clause in this chapter: Keynes says that it’s unlikely interest rates will go up if people expect inflation, since if people expected inflation prices would have gone up already. All it can do is change the price of hoarding — the interest rate. 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. “In estimating the prospects of investment, we must have regard, therefore, to the nerves and hysteria and even the digestions and reactions to the weather of those upon whose spontaneous activity it largely depends.”. And there are some, I believe, who practise the fourth, fifth and higher degrees. — III. Not only is income equal to expenditure, Y = C +I, but saving also equals investment, S = I. Further as income rises, saving also rises. They are “undoubtedly in the right [at present],” when investment is “unplanned and uncontrolled.” There’s no other way to raise employment. Obviously a lot more in absolute terms, but far less proportionately.) Another way to look at it is the more stuff we make for tomorrow, the less stuff we need to make tomorrow. But the money-wage level as a whole should be maintained as stable as possible, at any rate in the short period.”. [Tyler Cowen: “This is the best chapter in the book and one of the most important economics essays of all time. Therefore, Keynes called his treatise the General Theory The first half of this book will be dedicated to prying it open. Table 4.1 is meant to illustrate the income expenditure approach to macro equilibrium. How does money influence demand? It is the return of confidence, to speak in ordinary language, which is so insusceptible to control in an economy of individualistic capitalism. 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. The bought and the un bought do not differ in kind from one another in any fundamental respect. Still, the book isn’t exactly a smooth read. In 1937 he suffered a severe heart attack . According to Prof. Fisher, “…….. the national dividend or income consists solely of services received by ultimate consumers, whether from their material or from their human environment. For example, if the economy is in a deflationary gap situation but is also suffering from a 15 per cent rate of inflation, an increase in government spending or a cut in taxation designed to reduce the unemployment is likely to worsen the rate of inflation. The public can’t control the amount of hoarding, since that’s necessarily equal to the amount of cash. 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. Keynes argues that there is a paradox between the object of liquidity for the individual and the illiquidity of investment for the community (this is also where Keynes mentions “time and ignorance” [p. 155]). 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. Thirdly, Keynes spelt out the specific form which state intervention has to take to counter economic depression. The concept of underemployment equilibrium is the most revolutionary idea put forth by Keynes. 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". But how do they know what future sales will be? The right remedy for the trade cycle is not to be found in abolishing booms and thus keeping us permanently in a semi-slump; but in abolishing slumps and thus keeping us permanently in a quasi-boom. That it was adapted to carry a vast and consistent logical superstructure, gave it beauty. Keynes, the story goes, figured out the causes of the Great Depression and in doing so revolutionized the field of economics. 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. Assumptions of Keynes’s General Theory 5. I am sure that the power of vested interests is vastly exaggerated compared with the gradual encroachment of ideas. According to Prof. Pigou :”…. … But there are many difficulties which Gesell did not face. It was this theory of demand and supply of output as a whole which was neglected for more than 100 years and which Keynes analysed. Propensity to consume refers to the actual consumption that takes place at different levels of income. 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. Reading Keynes’ General Theory of Employment, Money, and Interest then is a sobering experience. He solved this problem in his own way. What will we do when we’ve built all the factories the people of the future can be expected to use? An uninterrupted process of transition, such as the above, to a new long-period position can be complicated in detail. THE GENERAL THEORY OF EMPLOYMENT SUMMARY 1.   Keynesians believe consumer demand is the primary driving force in an economy. Such public investment, he said, best achieves the multiplier effects. Keynes's main theory (including its dynamic elements) is presented in Chapters 2-15, 18, and 22, which are summarised here. [AS: This is the first use of that suspicious definition.]) Moreover, this behavior is not the outcome of a wrong‐headed propensity. That it could explain much social injustice and apparent cruelty as an inevitable incident in the scheme of progress, and the attempt to change such things as likely on the whole to do more harm than good, commended it to authority. Marginal prime costs and labor costs increase as industry is forced to use more expensive equipment and laborers, resulting in higher prices. A shorter account will be found in the article on Keynesian economics. ], 8: We return now to our main argument. 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’. In fact, monetary unit (money) had been employed usually as the standard of measurement. Thus, the user cost would be Rs. But even so, it will still be possible for communal saving through the agency of the State to be maintained at a level which will allow the growth of capital up to the point where it ceases to be scarce. We’ll call these hours labor-units and we’ll call the money that gets paid for them wage-units. 70 crores while their income is only Rs. 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. 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. Multiplier is the key concept of Keynes. … The insights here have yet to be fully mined.”]. But this is good, because otherwise wages would fall to zero in any downturn and the entire economy would shut down. His theory of interest depends upon it. Hayek economics was founded by famous economist Friedrich August von Hayek. In Summary: What is the difference between Hayek and Keynes? Static Analysis: The ‘General Theory’ does not trace out the effect of the future on the present economic events clearly. What this amounts to is Say’s Law: supply creates its own demand. “An act of individual saving means — so to speak — a decision not to have dinner to-day.” But it is not a promise to have dinner tomorrow — it doesn’t replace current demand with future demand; it decreases demand altogether. Therefore, it is important to understand what determines the amount of investment. Meanwhile, like other academic economists, I treated his profoundly original strivings as being no better than those of a crank. 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 works, it’s just slow — if you want to get people employed quickly, you’re better off starting with building the factories. They didn’t sit down and calculate whether they could have made more money buying bonds instead. If he is successful, that will only confirm the general belief in his rashness; and if in the short run he is unsuccessful, which is very likely, he will not receive much mercy.
