Analysis indicates that the Yoruba were taller than other West African peoples in the early nineteenth century. Disease, workloads, and environmental or genetic factors explain little of this differential. Rather, it appears due to a superior nutritional status made possible by Yoruba social structures, in particular, Yoruba towns. Yoruba stature declined both absolutely and relatively over the forty years corresponding to the collapse of the Oyo Empire. Regression analysis suggests a systematic relationship between these two events.

Recent theory has predicted that if competing technologies operate under dynamic increasing returns, one, possibly inferior, technology will dominate the market. The history of nuclear power technology is used to illustrate these results. Light water is considered inferior to other technologies, yet it dominates the market for power reactors. This is largely due to the early adoption and heavy development by the U.S. Navy of light water for submarine propulsion. When a market for civilian power emerged, light water had a large head start, and by the time other technologies were ready to enter the market, light water was entrenched.

The only official measure of overall Soviet munitions output in World War II, first published in 1965, was based on changes in values, not volumes, and grossly understates change in the level of real Soviet war production. Subsequently published official data on production of ground and air munitions in physical units, supplemented by information about real spending on naval munitions, provide foundations for a new index. During the war the USSR produced more munitions than Great Britain or Germany, but much less than the United States.

This article examines the workers' standard of living in the cotton textile industry of Northwest England from 1806 to 1850. Hedonic earnings regressions using 1835 data suggest that power-loom weavers required substantial compensation for the high rents and poor sanitation of urban locations. Adjusting earnings in the factory sector for the impact of urbanization cuts growth in living standards by 10 percent, or up to one-quarter of gains realized by 1850. Inclusion of those employed in the handloom sector implies that any improvements in the living standards of all workers in the industry appeared only during the 1840s.

Quantiative and qualitative evidence suggest that the returns to irrigation in France were similar during the eighteenth and nineteenth centuries. The Old Regime failed to develop irrigation because of fragmented political authority over rights of eminent domain. Since many groups could hold projects up, transaction costs increased dramatically. Reforms enacted during the French Revolution reduced the costs of securing rights of eminent domain.

An early long-running federal social policy experiment was the preferential hiring of American Indians at agencies, reserations, and shools. This government employment was designed to accelerate the assimilation of the natives and to reduce their resistance to education and economic change. Instead, the program inadvertently created a form of dependency. This ironic outcome was due to the power of the natives to shape the policy according to their needs and values.
