i) Labour expended or labour commanded?
Labour expended or labour commanded? Malthus and Ricardo held fundamentally different opinions on this question; one hundred years ago they engaged in continuing debate throughout their life as scholars. The streams of thought flowing from the work of Adam Smith became divided, and the division continues up to the present. This is cause for concern. Even today the problem has not yet resolved, rather it seems to have become more complicated. So to re-examine exactly what Malthus and Ricardo said can never be a fruitless task. Malthus wrote: ‘Adam Smith, in his chapter on the real and nominal price of commodities, in which he considers labour as an universal and accurate measure of value, has introduced some confusion into his inquiry by not adhering strictly to the same mode of applying the labour which he proposes for a measure. Sometimes he speaks of the value of a commodity as being measured [‘determined’ in the first edition] by the quantity of labour which its production has cost, and sometimes by the quantity of labour which it will command in exchange’. These sentences appear in both the first and the second editions of Malthus’s Principles of Political Economy, while the following passage can be found only in the second edition. (See the first sentences of Section 4 of chapter 2 in the first edition [p. 85], the seventh paragraph of Section 4 of the same chapter in the second edition [p. 84]). ‘It is in the latter sense, however, in which he applies it much the most frequently, and on which he evidently lays the chief stress. “The value of any commodity,” he says, “to the person who possesses it, and who means not to use or consume it himself, but to exchange it for other commodities, is equal to the quantity of labour which it enables him to purchase or command. Labour, therefore, is the real measure of the exchangeable value of all commodities”.[Smith’s sentences quoted by Fukuda in English] Other expressions in the same chapter apply labour as a measure of value in the same way; […] It would not then be worthwhile to inquire how far labour may be considered as a measure of value, when applied in the way which Adam Smith has practically rejected (meaning labour expended [phrase inserted by Fukuda]) in reference to the more advanced stages of society, if this mode of applying it had not been adopted by some distinguished modern writers as the foundation of a new theory of value’. (p. 85 in the second edition)
It is of course Ricardo who is called to be among the ‘distinguished modern writers’. In fact Ricardo writes the following in Principles of Political Economy and Taxation:
Adam Smith, who so accurately defined the original source of exchangeable value, and who was bound in consistency to maintain, that all things became more or less valuable in proportion as more or less labour was bestowed on their production, has himself erected another standard measure of value, and speaks of things being more or less valuable, in proportion as they will exchange for more or less of this standard measure […]; not the quantity of labour bestowed on the production of any object, but the quantity which it can command in the market: as if these were two equivalent expressions.
If this were true, ‘either might accurately measure the variations of other things: but they are not equal’ (Page 6 in the first edition, no alteration in the third edition [Fukuda quotes from The Works edited and published by McCulloch in 1846 and gives the page numbers for this edition. We add the volume and page numbers in the Sraffa edition, indicated e.g. I/13–4, ditto infra]). Ricardo continues as follows:
It cannot then be correct, to say with Adam Smith, “that as labour may sometimes purchase a greater, and sometimes a smaller quantity of goods, it is their value which varies, not that of the labour which purchases them;” […] but it is correct to say […] “that the proportion between the quantities of labour necessary for acquiring different objects seems to be the only circumstance which can afford any rule for exchanging them for one another” [Smith’s sentences quoted by Fukuda in English]; or in other words, that it is the comparative quantity of commodities which labour will produce, that determines their present or past relative value, and not the comparative quantities of commodities, which are given to the labourer in exchange for his labour.
[I/16–7, emphasis added. Pages 10–11 in the first edition, the same text appearing in the third edition.]
Put simply, the above means that the comparative value of one commodity with another depends solely on the process of production using labour, and not on the amount distributed as wages.
Ricardo is not always coherent in maintaining his doctrine that labour is value. Although there are not many textual modifications between the first and the third edition of Principles, there are non-trivial substantive differences. Moreover, his letters to Malthus, McCulloch and Hutches Trower [published toward the end of the nineteenth century by Bonar and J. H. Hollander: see Introduction, p. 19] show that he did not cease thinking about this problem, gradually changing his mind to the approach to the production cost theory of value which he bequeathed to posterity via John Stuart Mill. Nevertheless, there was almost no change in his argument endorsing the labour expended theory and rejecting the idea of a labour commanded theory; and he eventually and reluctantly concluded that an invariable measure of value does not exist. He lamented this in a letter to Malthus, saying that ‘We both have failed’ [quoted in English] (letter of 15th August 1823, IX/352). For Malthus however circumstances were different. There are major differences between the first edition (1820) and the second edition (1836) of his Principles of Political Economy, although not so great as between the first and second editions of his Essay on the Principle of Population. Regarding the passage quoted above, while in the first edition of Malthus’s Principles the title of Section 4 was ‘Of the labour which a commodity has cost’, in the second edition it was modified to ‘Of the labour which has been employed on a commodity’ [these two titles quoted in English, in the original the titles of both editions are entirely italicised]. And the first edition lacks the paragraph quoted above beginning with ‘however’ [pp. 61–2 above]; instead we find there the following sentences [following two quotations from Malthus are from original English texts]:
These two measures are essentially different; and, though certainly neither of them can come under the description of a standard, one of them is a very much more useful and accurate measure of value than the other.
When we consider the degree in which labour is fitted to be a measure of value in the first sense used by Adam Smith, that is, in reference to the quantity of labour which a commodity has cost in its production, we shall find it radically defective.
[Emphasis by Fukuda. Page 85 in the first edition]
And on page 87 Malthus writes:
I cannot, therefore, agree either with Adam Smith or Mr. Ricardo in thinking that, “in that rude state of society which precedes both the accumulation of capital and the appropriation of land, the proportion between the quantities of labour necessary for acquiring different objects seems to be the only circumstance which can afford any rule for exchanging them for one another.”
[cf. I/13]
What attracts our attention here is the fact that, in the letter to Malthus of 15th August 1823 sent from Gatcombe Park, hence only 26 days before his death, Ricardo mentions this problem and writes: ‘The difference between us is this, you say a commodity is dear because it will command a great quantity of labour, I say it is only dear when a great quantity has been bestowed on its production. In India a commodity may be produced with 20 days labour and may command 30 days labour. In England it may be produced by 25 days labour and command only 29. According to you this commodity is dearer in India, according to me it is dearer in England’ [IX/348]. Bonar writes in his Introduction that the letters sent from Malthus to Ricardo can no longer be traced, so we cannot know what the response to this letter was. Ricardo was continuing his debates with Malthus unaware of his imminent death; something that allows us to sense the degree of his zeal for truth, while we can also see that this problem continued to preoccupy him. He returned to the same problem in his last letter to Malthus on 31st August. He had concluded the letter of the 15th by writing that ‘I am just now warm in the subject, and cannot do better than disburden myself on paper’ [IX/352, quoted in English], which explains why he wrote this last letter. He wrote there that: ‘I have only a few words more to say on the subject of value, and I have done. You cannot avail yourself of the argument that a foot may measure the variable height of a man, altho’ the variable height of a man cannot truly measure the foot, because you have agreed that under certain circumstances the man’s height is not variable, and it is to those circumstances that I always refer’ [IX/380]. And he concludes this letter with the following words: ‘And now, my dear Malthus, I have done. Like other disputants after much discussion we each retain our own opinions. These discussions however never influence our friendship; I should not like you more than I do if you agreed in opinion with me’ [IX/382, quoted in English]. He died on 11th September 1823. Malthus survived for another 11 years and continued thinking about this problem. Four years after the death of Ricardo he published Definitions in Political Economy, presenting his new ideas about the theory of value, which had always been in opposition to those of Ricardo. Definitions is indispensable for an understanding of the changes in Malthus’s thinking. He could not convince himself, and thought about the matter again and again. He attempted to prepare a new edition of his Principles making use of the results of his later studies, applying himself intensively to this task. However, he died in 1834 before he could finally complete the work. Fortunately the new edition was published as the second edition after his death by his two friends, so that we are aware of his final ideas about this problem. In this second edition Malthus newly inserted the following extremely notable passage as a footnote, at the beginning of Section 4 of chapter 2:
The labour worked up in a commodity is the principal CAUSE of its value, but it will appear in this chapter that it is not a measure of it. The labour which a commodity will command is NOT the CAUSE of its value, but it will appear in the next chapter to be the measure of it.
[Footnote to page 83 in the second edition (words in capitals are italics in the original and emphases in italics are by Fukuda)]
Ricardo as well as Adam Smith did not distinguish between the cause and the measure of value, arguing only that labour was value. They spoke sometimes of labour as a ‘source’, a ‘foundation’ or a ‘circumstance’, at other times as a ‘measure’ or ‘standard measure’, and often used the word ‘determine’ [some words in quotation marks above are written in English]. While in the first edition Malthus was also very ambiguous on th...
