Demographic, Residential, and Socioeconomic Effects on the Distribution of 19th Century African-American Body Mass Index Values
Little research exists on the body mass index values of late 19th and early 20th century African-Americans. Using a new BMI data set and robust statistics, this paper demonstrates that late 19th and early 20th century black BMI variation by age increased in their mid-30s but declined at older ages when worker physical productivity declined. Throughout the late 19th and early 20th centuries, black BMIs decreased across the distribution, indicating that the 20th century increase in black BMIs did not have its origin in the 19th century. During industrialization, black BMIs were lower in Kentucky, Missouri, and urban Philadelphia.nineteenth century U.S. economic development, body mass index, 19th century race relations

Geography, Insolation, and Institutional Change in 19th Century African-American andWhite Stature in Southern States
The use of height data to measure living standards is now a well-established method in the economic literature. While much is known about 19th century black legal and material conditions, less is known about how 19th century biological conditions were related to the physical environment and institutional change. Although modern blacks and whites reach similar terminal statures when brought to maturity under similar biological conditions, 19thcentury African-American statures in Southern states were consistently shorter than whites, indicating a uniquely 19th century phenomenon may have influenced black stature growth. It is geography and direct sunlight (insolation) that present a striking attribute of 19th century black and white statures, and greater insolation is documented here to be associated with taller black and white statures.nineteenth century Southern black and white statures, insolation, vitamin D
Slave Prices, Geography and Insolation in 19th Century African-American Stature
The use of height data to measure living standards is now a well-established method in the economic literature. Moreover, while much is known about 19th century black legal and material conditions, less is known about how 19th century institutional arrangements were related to black stature. Although modern blacks and whites reach similar terminal statures when brought to maturity under optimal biological conditions, 19th century African-American statures were consistently shorter than whites, indicating a uniquely 19th century phenomenon may have inhibited black stature growth. It is geography and insolation that present the most striking attribute for 19th century black stature, and greater insolation and higher slave prices are documented here to be associated with taller black statures.nineteenth century, African-American stature, slave prices, insolation, vitamin D
Industrial development under institutional frailty: the development of the Mexican textile industry in the nineteenth century
La Historia Económica en Latinoamérica. Edición a cargo de Pablo Martín Aceña, Adolfo Meisel, Carlos Newland.Editada en la Fundación Empresa PúblicaLa industria textil moderna apareció en México tempranamente y creció
de forma continua a lo largo del siglo XIX. Sin embargo, esto no se tradujo
en un proceso de industrialización exitoso como resultado de altos costos
de transporte y fragilidad institucional: concepto que incluye la incertidumbre,
la debilidad y la fragmentación institucionales. La fragilidad institucional generó
una política arancelaría capturada que otorgaba bajos niveles de protección
efectiva a la industria, un mercado financiero atrasado que limitó los recursos
disponibles al crecimiento industrial, y un crecimiento en los costos de transporte
debido a las alcabalas. Los altos costos de transporte fragmentaron el
mercado nacional y como resultado generaron una industria geográficamente
dispersa.Modern texture manufacture appeared early in México and grew continuously
through the 19th century. Yet, it did not transíate into a successful
industrialization process as a result of naturally endowed high transportation
costs and institutional frailty: a concept that encompasses institutional uncertainty,
weakness and fragmentation. Institutional frailty generated a captured
tariff policy that gave low effective protection to the industry, a backward
financial market that limited resources available for industrial growth, and
increased transportation costs through inter-state tariff barriers. High transportation
costs fragmented the national market and as a result, the textile
industry grew geographically dispersed.Publicad
Geography and Insolation in 19th Century US African-American and White Statures

A Biogeographic History of the Plains Bison Focusing on Population and Range Dynamics
Early bison originated in Asia and migrated to North America by means of the Bering Land Bridge, which opened around 600,000 years ago. Just after the Wisconsin glaciation (11, 700 years ago), there were two allopatric species of bison residing in North American - the plains bison (Bos bison bison), and the woodland bison (Bos bison athabasce). European explorers and settlers recorded incredible numbers of bison in most parts of the present day United States. Bison thrived in North America until the mid-19th century, but experienced a drastic decline in population from about 60 million to only 1,000 as European settlers headed west. Currently, 95% of extant bison are part of industrial corporations that raise them for their meat and other byproducts. This paper explores the natural history, geographic distribution, near extinction, recovery, and current status of the bison within the United States
Demographic, Residential, and Socioeconomic Effects on the Distribution of 19th Century US White Statures
Using a source of 19th century US state prison records, this study addresses European-American stature variation. The most commonly cited sources for stature variation are diets, disease, and work effort. However, vitamin D is also vital in human statures and health. This paper demonstrates that 19th century white statures were positively associated with direct sunlight, which is the primary source of vitamin D in mammals. Stature and insolation are associated with occupations, and workers who spent more time outdoors produced more vitamin D and grew taller. White statures also decreased throughout the 19th century, and this stature diminution is observed across the stature distribution.19th US white statures, vitamin D, solar radiation, quantile regression
