Nineteenth century white US statures varied with nutrition, disease exposure, and the physical environment. An additional explanation for stature growth is vitamin D production. Vitamin D is produced internally by the synthesis of cholesterol and sunlight in the epidermis. However, studies that...

By using a new source of 19th century Texas state prison records, the present study contrasts the biological living conditions of comparable blacks and whites in the American South between the Civil War and Reconstruction. White stature exceeded black stature. Between 1850 and 1870, black...

Little research has been done on the body mass index values of 19th century US African-Americans and whites. This paper uses 19th century US prison records to demonstrate that although modern BMIs have increased in the 20th century, 19th century black and white BMIs were distributed...

Much has been written about the modern obesity epidemic, and historical BMIs are low compared to their modern counterparts. However, interpreting BMI variation is difficult because BMIs increase when weight increases or when stature decreases, and the two have different implications for human...

Using data from late 19th and early 20th century US prisons, this study estimates the basal metabolic rates and calories for Americans of European descent. Throughout the 19th century, white basal metabolic rates (BMRs) and calories declined across their respective distributions, and much of the...

This paper calls into question the currently most influential model of international trade. An empirical finding by Trefler (2004, AER) and others that industrial productivity increases more strongly in liberalized industries than in non-liberalized industries has been widely accepted as...
