The factors in the increase of population are evidently (1) migration, (2) the " natural increase " of population, i.e. the excess of births over deaths. The annual natural increase has fallen in England and Wales from 14'5 per 1000 of the population for the period 1876-1880, to 12-1 in 1901-1905, in consequence of the fact that though the death-rate fell from 20*8 to 16 per thousand, the birth-rate fell from 35-3 to 281. The birth-rate in England and Wales, for the period since the Civil Registration Act of 1837, reached its maximum in the period 1870-1876, and has since shown a material decline.
The extent of this decline is shown in the next table:
Birth-bates (england And Wales).
As regards the decline in the birth-rate generally, the Registrar-General observes:
"There are sufficient grounds for stating that during the past 30 years approximately 14 per cent, of the decline in the birth-rate (based on the proportion of births to the female population aged 15-45 years) is due to the decrease in the proportion of married women in the female population of conceptive ages, and that over 7 per cent, is due to the decrease of illegitimacy. With regard to the remaining 79 per cent, of the decrease, although some of the reduced fertility may be ascribed to changes in the age constitution of married women, there can be little doubt that much of it is due to deliberate restriction of child-bearing." The decline in the birth-rate, whatever may be its cause, is a feature common to the birth statistics of most European countries. The statistics may be studied in the General Report on the Census of 1901, and in the Annual Reports of the Registrar-General. The figures are conveniently collected in the Bluebook, Public Health and Social Conditions, prepared by the Local Government Board (1909). The most detailed statistical analysis of the facts is to be found in a paper by Newsholme and Stevenson, and another by Yule, in the Journal of the Royal Statistical Society (March 1906).
Q.—Profits (p. 421)
The most powerful impulse to fresh discussion of the nature of profits was given by the late General Walker, in the emphasis laid by him on " the function of the entrepreneur," and his view that " profits are a species of the same genus as rent," and " do not form a part of the price of manufactured products "; see his Wages Question (1876), ch. 14, and Political Economy (1883). In this discussion it has become usual to distinguish more sharply than the earlier writers between Interest and "pure" or "net" Profits; and there is now a large literature on both these topics. As to Interest, much influence has been exerted by the doctrine of the Austrian writer, Bohm-Bawerk, which explains interest as "a premium on present as against future things "; see BohmBawerk, Capital and Interest (Eng. trans. 1890), and Positive Theory of Capital (Eng. trans. 1891). Of the writings this has called forth it may be sufficient to refer to Pierson, Principles of Economics (Eng. trans. 1902), part i. ch. 4, § 5, and to Cassel, The Nature and Necessity of Interest (1903).
On Profit, recent writings are largely influenced by the conceptions of (1) a " quasi-rent," (2) " the marginal entrepreneur," and (3) " long and short periods." The present state of the discussion may be seen in Marshall, Principles, bk. vi. chs. 6-8; Clark, Essentials of Economic Theory (1907), pp. 117 seq.; Seager, Introduction to Economics (3rd ed. 1906), ch. 10; and in Conrad's Grundriss, § 84, and Gide's Cours, pp. 674 seq. The treatment of the subject by Schmoller, Grundriss, §§ 231-2 (Principes, vol. iv.), will be found illuminating. The " tendency " of profits and wages to an equality has been commented upon frequently by Cliffe Leslie, as in his articles on The Political Economy of Adam Smith and On the Philosophical Method of Political Economy, reprinted in his Essays (1879).
R.—Kent (p. 434)
Criticisms of the Ricardian doctrine of rent, or of its formulation, are to be found in Sidgwick, Principles, bk. ii. ch. 8, and in Nicholson, Principles, vol. i. bk. ii. ch. 14; and it is restated in Pierson, Principles, pt. i. ch. 2, and in Marshall, Principles, bk. vi. ch. 9.
S.—The Theory Of Value (p. 482)
It is on this subject—as to which Mill remarked, in 1848, that " happily there is nothing in the laws of value which remains for the present or any future writer to clear up; the theory of the subject is complete" (p. 436)—that theoretic discussion has mainly turned during the last four decades, owing chiefly to the writings of Jevons, of Menger and the other representatives of the Austrian school, and of Clark and his American followers. The characteristic of all these writers is to approach the problem from the side of demand, and to find the key to value in Final or Marginal Utility (Grenznutz). The best introduction to the discussion is through Jevons, Theory of Political Economy (1871; 2nd ed. revised, 1879), chs. 3 and 4; and through Bonar's article on The Austrian Economists in the (Harvard) Quarterly Journal of Economics, iii. (Oct. 1888); and Smart, An Introduction to the Theory of Value on the lines of Menger, Wieser and Bohm-Bawerk (1891). Wieser's Natural Value (Eng. trans. 1893) attempts to apply the doctrine to the whole problem of Distribution. For the present state of the discussion see Marshall, Principles, i. bk. v.; Clark, Essentials, chs. 6 and 7; and Schmoller, Grundriss, §§ 171-2 (in French, Principes, vol. iii.).
Mill's doctrine of Cost of Production was attacked by Cairnes in his Some Leading Principles of Political Economy newly expounded (1874), soon after Mill's death. See hereon Marshall in Fortnightly Review (April 1876), and Principles, book v. ch. 3, § 2. Cairnes contributed an important consideration to the discussion by the emphasis which he laid on " Non-competing Groups." T.—The Value Of Money (p. 506)
For other expositions of "the Quantity Theory of Prices," see Walker, Money (1878), chs. 3-8; and Nicholson, Money and Monetary Problems (1888; 4th ed. 1897), chs. 5-7. For a criticism, see Scott, Money and Banking (N. Y. 1903), ch. 4. An attempt to test the doctrine statistically is made by Kemmerer, Money and Credit Instruments in their relation to General Prices (N. Y. 1907). For the sense of " money " in modern business, see Withers, The Meaning of Money (1909).
U.—Bimetallism (p. 510)
For the main points of the controversy on this subject, which had hardly begun when Mill wrote in 1848, see Jevons, Money (1875), ch. 12 (with his acceptance of the view of the "compensatory action" of a double standard system); Gibbs and Grenfell, The Bimetallic Controversy (1886),—a collection of pamphlets, speeches, &c., on both sides; Nicholson, Money and Monetary Problems; Walker, International Bimetallism (1896); Darwin, Bimetallism (1898); and Carlile, The Evolution of Modern Money (1901). An extreme monometallist position is represented in Giffen, Case against Bimetallism (1892).
V.—International Values (p. 606)
The Ricardian doctrine, followed and carried further by Mill, has hitherto remained the almost exclusive possession of English economists. It has been expounded by Cairnes, Leading Principles, part iii. ch. 3, and by Bastable, Theory of International Trade (2nd ed. 1897). It has been objected to from two diametrically opposite points of view. Transferability of capital and labour, it has been argued, is true of international trade as well as of domestic, so that no separate theory is necessary for the determination of international values; e.g. Hobson, International Trade (1904). On the other hand it has been asserted that such a transferability is true neither of domestic nor of international trade, and that therefore it is necessary to reject both the Ricardian doctrine of home values and the Ricardian doctrine of international values; e.g. Cliffe Leslie, Essays in Political and Moral Philosophy (1879), Preface. A different theory has been put forward by Sidgwick, Principles, bk. ii. ch. 3. A mathematical treatment of the whole subject, with a criticism of all the leading writers, will be found in a series of articles by Edgeworth on The Theory of International Values in the Economic Journal, vol. iv. (1894). Bastable and Edgeworth, while admiring and accepting Mill's first statement of the theory (ch. 18, §§ 1-5), agree in regarding " the superstructure of later date " (§§ 6-8) as " laborious and confusing."
W.—The Regulation Of Currency (p. 677)
The question of the effect of the Bank Charter Act has lost much of its importance in consequence of the growing use of cheques. These cheques are now largely drawn not against actual deposits but against banking credits; so that banks, while abandoning more and more the issue of notes, "manufacture money " on a vast scale in.another way. Hereon see Withers, Meaning
of Money, chs. 3 and 5. On the effect of an increase in the supply of gold, see Walker, Money, pt. i. ch. 4, and Withers, ch. 1.
X.—Prices In The Nineteenth Century (p. 704)
The actual movement of prices has been much investigated since the time of Mill; and attempts, in large measure successful, have been made by Jevons and others to reduce the statement of it to precision by the use of Index Numbers. On the theory and practice of Index Numbers, see article by Edgeworth, s. v., in Palgrave's Dictionary of Political Economy, vol. ii. ; Fountain's Memorandum in Report on Wholesale and Retail Prices (Board of Trade, 1903); and the article of Flux in (Harvard) Quarterly Journal of Economics (Aug. 1907).
The following table, taken from the Blue-book of the Local Government Board on Public Health and Social Conditions (1909), presents the conclusions of Sauerbeck as to prices, and of Bowley as to wages, in a form convenient for comparison.
Index Numbers ShoWing Course Of Average Wholesale Prices And General Money Wages.
[The wages and prices in 1850 being taken as 100; wages and prices in other years in percentages of 1850 figures.]
Note.—The Index Numbers here given have been calculated as regards Wages for the years to 1873 on the averages ascertained by Mr. Bowley—see the Economic Journal (Dec. 1898) and the Journal of the Royal Statistical Society (Dec. 1899)—and for later years on the percentages in the 12th Abstract of Labour Statistics of the United Kingdom (1906-7), p. 54. As regards Prices, the Numbers are based on the Index Numbers calculated by Mr. Sauerbeck— see Report on Wholesale and Retail Prices (1903), p. 451, and particulars in the Journal of the Royal Statistical Society (March 1908).
