The records of the United States Army, which hired civilian workers in the nineteenth century, have produced a large sample of wage rates. New estimates of nominal daily wage rates from 1820 to 1856 are presented. There is no evidence of a long-term increase in the skill differential. The growth of real wages in the Northeast appears to have been slower and more erratic than previously thought. Regional trends in wages are consistent with other evidence on patterns of regional growth and internal migration.

A decline in nutritional status is inferred from data on the height and weight of West Point cadets in the antebellum period. The decline was geographically widespread and affected farmers and blue-collar workers the most; middle-class cadets did not experience a decline in nutritional status until the Civil War. Nutritional status declined because meat output did not keep pace with population growth. Urbanization and the expansion of the industrial labor force increased the demand for food. However, the agricultural labor force grew at a slower pace, and productivity growth in food production was insufficient to redress the imbalance.

Most explanations of trends in women's work emphasize women's role in childbearing, along with technological and organizational changes in production. The explanations neglect an important factor: the need to control sexuality in order to secure demographic order. Segregated employment enabled almost all family members to work, while discouraging heterosexual intimacy. Nineteenth-century attitudes illustrate the anxiety felt when unrelated men and women worked together. The argument is tested by correlating regional variation in illegitimacy, as a measure of failed social control, with variation in sex segregation.

In the southern Russian coal and steel region between 1874 and 1900, labor policy was outlined by the Russian managers of predominantly foreign firms through the Association of Southern Coal and Steel Producers. This policy was shaped by chronic labor shortage, by the strained relations between industry and local government, and by managers' sensitivity to their position as spokesmen for foreign interests. The posture southern managers developed was that of welfare capitalism. Considerable expenditure on wages and welfare, however, did not establish labor peace.

This article analyzes, with particular reference to Britain, the technological transformation in coal gas manufacture around 1900. The timing of the innovation seems to be explained by the nature of the technology itself, by Rosenberg's “technical complementarity.” The rate of diffusion is analyzed by means of an inter-firm model which points to the importance of technical interrelatedness and the need to scrap old plant and of wage costs, which encouraged some firms to hasten scrapping. Different countries chose between the range of new technologies available largely on the basis of compatibility with existing plant and the cost of raw materials.
