It will be observed that the four points made in this citation all concern influences which make the entrepreneur’s expenses of production out of proportion to the total quantity of labor which his outlay of money directly and indirectly remunerates. For instance, the fifth point regarding the use of imported raw-material or machinery refers to the fact that $1,000 worth of production goods bought abroad by an entrepreneur may have cost more or less labor than $1,000 worth of raw-material of home production. As Ricardo himself points out (in Chapter VII of his _Principles_), the exchange value of an imported commodity does not depend on its labor cost abroad compared with the home labor cost of the goods against which it exchanges. But the $1,000 spent by one entrepreneur counts just the same as that spent by another in determining the “necessary price” of the respective commodities which they produce. Thus there is here one source of disproportionality between necessary prices and actual labor costs. 5. What is the position of Ricardo with respect to these seven counts? He acknowledged all but the claim that rent causes an aberration of normal value from the position required by labor cost. That is, in the language of the day he denied that “rent enters into price.” He not only acknowledged, but himself stated the other points. How fully he treats the question of the different proportions of “fixed and circulating” capital, we have seen.[122] As for the “acknowledged” effects of taxation, the reference is to Ricardo’s own statements, scattered throughout his various chapters on taxation, that this and that tax will raise prices. Ricardo was perfectly aware of the effects of monopoly, and of the influence of temporary oscillations of supply and demand.[123] The old question whether “rent enters into price” could very properly be discussed in a history of the labor theory of value. Since, however, the question is large enough to warrant separate discussion, and has in recent times received it in many prominent places, we shall be content merely to point out the conflict between Malthus and Ricardo, and to take the stand that recent discussion has shown that ground rent enters into price in the same sense as wages, or interest on capital other than land. Ricardo said rent does not and cannot enter in the least degree into price. Says Malthus: “It appears to me essential, both to correctness of language and correctness of meaning to say that the cost of producing any commodity is made up of all the wages, all the profits, and all the rent which ... are necessary to bring that particular commodity to market in the quantity required.”[124]
