This article presents new estimates of the Italian utilities industries' production from 1861 to 1913. The improvements over the currently available series include the restriction of the electricity series to the production of the electric utilities, the extrapolation of the gas production series to 1861, and the calculation of production series for the water supply industry. These new estimates suggest that the existing aggregate production series significantly overstates the utilities' growth rate. The existing utilities series for other countries do not incorporate separate estimates for the water supply industry, and also appear to overstate the industryapos;s growth rate.

3 A full account of the derivation of these estimates is available from the author on request, and will be published in due course in Fenoaltea, Stefano, Italian Industrial Production, 1861–1913: A Statistical Reconstruction (New York, forthcoming).Google Scholar This study identifies Italy with the area within the Kingdom's borders from 1871 to 1918. It makes no attempt to obtain regionally disaggregated estimates, even though individual time series are often constructed, or reconstructed, from place-specific data.
4 The calculation of real value added as output weighted by base-year value added is of course justified by its minimal data requirements rather than by its theoretical optimality; but it does not appear to be as poor a measure, next to the common alternatives, as is generally believed.

8 Fuà, Sviluppo economico, vol. 3, pp. 469–70. Before the appearance of electric power production, therefore, the Vitali series (col. 5) should vary in strict proportion to the Istat aggregate current-price series (col. 4). In the 1860s, however, it moves in strict proportion to the Istat current-price series for gas alone (col. 2).Google Scholar

10 In the Sommario, pp. 133, 135, electricity production grows from 50 million kilowatt-hours in 1896 to 160 in 1900 and 1,150 in 1908, and gas production grows from 174 million cubic meters in 1896 to 194 in 1900 and 307 in 1908;Google Scholar in the Reddito nazionale, pp. 221–22, value added in 1900 equals 25 million tire in electricity production and 29 million lire in gas production.Google Scholar
11 Since Gerschenkron's industry indices are combined with weights corresponding to each industry's value added in 1903, the weight here attributed to the utilities is obtained from the Reddito nazionale value added figures for 1903 as the ratio of the utilities' figure (96 million lire) to the sum of those for the utilities and the six industries in Gerschenkron's index (1,719 million lire).Google Scholar

Since my index seems excessively sensitive to cyclical fluctuations, it probably overstates the growth rate actually achieved early in this century.

The asset value figures grow surprisingly slowly (from $221 million in 1880 to $275 million in 1912); the retrospective extrapolation, based on the apparent growth from 1900 to 1904, would seem to be defective.

In a technical sense, gas was produced for heat rather than light ever since the adoption of the Welsbach incandescent gas mantle (patented 1885). This also allowed a change in the manufacturing process to one closer to that of the coking industry and accounted for a good part of the growth in fuel efficiency noted above.

70 Setting 1861 = 100, in 1870 the Vitali series equals 300, and the present series 141; setting 1870 = 100, in 1900 the Vitali series equals 533, and the present series 523; setting 1900 = 100, in 1913 the Vitali series equals 649, and the present series 366. The vitali series also grows less smoothly than the present one; but a recalculation of his series suggests that its sharp dip in 1895 is due to clerical or typographical error.Google Scholar
71 See note 8. While the Istat series for the water supply industry also grows rather faster than the present one, its inclusion would have reduced the growth of the Vitali series over this period from threefold to twofold.Google Scholar
72 As noted above, the gas production which Istat appears to have taken as a complete figure for 1868 was in fact a less than complete figure for 1865. The data in the Statistica mineraria, p. LI suggest that current-price value added in 1865 was in excess of 6 million lire, or twice the Istat estimate for that year. The Enciclopedia italiana, vol. 16, pp. 413–14 indicates that the Italian gas utilities experienced their initial rapid growth in the 1830s and 1840s.Google Scholar
73 Fuà, Sviluppo economico, vol. 3, p. 470;Google ScholarSommario, pp. 133, 135, noting the rapid growth of tax-exempt gas consumption and of metallurgical coke production. The recalculation of Vitali's series suggests that his estimates for the water supply industry also grow excessively fast; since they are obtained as a percentage of those for electricity and gas together, however, this discrepancy is itself the result of the inappropriate relative weights assigned to those industries.
74 In addition, as noted above, various elements of the local water works are assumed to grow as other such elements, or as the population served.Google Scholar
75 Data on the length of the gas distribution networks may be found in the Annuario città, e.g., 1906, pp. 92–96, 1913–1914, pp. 230–32. These suggest that the average length per unit of output in large cities was significantly less than in smaller ones, and declining over time; however, the national average may have been stabilized by the extension of the industry to progressively smaller towns.Google Scholar

77 Derry and Williams, Short History, pp. 510–14. From 1861 to 1913, the aqueduct sector grew ninefold. The local water works grew elevenfold if the allowance for public wells and cisterns is included, and fourteenfold if it is excluded. The gas industry grew fourteenfold.Google Scholar
78 This refinement would be warranted if old aqueducts and public wells and cisterns appeared to be as significant in Britain and Germany as in Italy. In general, it may be noted, the problem is that of estimating an unknown series from a sample of known series; as in a regression, there is no need to impose equiproportionate weights on the components of that sample, or to restrict the sample to the other members of the same industry group.Google Scholar
79 The 1907 census value added weights underlying the Feinstein series equal £5.6 million for electricity and £17.3 million for gas. The present figures allow water supply its corresponding weight (£9.1 million). The lower figure assumes water supply grew from 1855 through 1907 to 1913 at an average annual rate of 3.74 percent, against 4.36 percent for gas; the higher figure assumes that it grew in strict proportion to gas.Google Scholar See Feinstein, National Income, p. 210;Google Scholar Board of Trade, Census of Production.

80 The 1907 weights underlying the Hoffman series are reported only in relative terms (47.3 percent for electricity, and 52.7 percent for gas). The present figures allow the water supply industry a 1907 weight equal to 30.6 percent of the sum of electricity and gas, as suggested by the German employment data (23,200 in electricity, 39,100 in gas, and 10,300 in water supply) and the British value added per worker data (£247 in electricity, £207 in gas, and £411 in water supply). The lower figure assumes that water supply grew from 1868 through 1907 to 1913 at an average annual rate of 6.11 percent, against 7.13 percent for gas; the higher figure assumes that it grew in strict proportion to gas. If the relative weights of electricity and gas are also calculated from the German employment and British value added per worker data, the estimates of the utilities' growth from 1868 to 1913 are further reduced (to thirty-three-or thirty-eightfold). Curiously, Hoffman's weights for electricity and gas do not correspond to the employment figures which they are said to reflect.
