We experimentally test overconfidence in investment decisions by offering participants the possibility to substitute their own for alternative investment choices. Overall, 149 subjects participated in two experiments, one with just one risky asset, the other with two risky assets. Overconfidence...

Peer and cohort effects are important in health economics, and obesity may be related to social relationships, where obese individuals interact with other obese individuals. There were significant 19th century cohort effects, where BMIs were related to the cohort that an individual belonged....

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...

The use of height data to measure living standards is now a well-established method in the economic literature, and heights are related with vitamin D. Although African-Americans and whites have the genetic ability to reach similar terminal statures, 19th century blacks were consistently shorter...

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...

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...

Using a new source of 19th century state prison records, this study contrasts the biological living conditions of comparable US African-American and white female statures during economic development. Black and white female statures varied regionally, and white Southeastern and black Southwestern...

The use of height data to measure living standards is now a well-established method in economics. Nevertheless, a neglected area in historical stature studies is the relationship between stature and family size, and statures are documented here to be positively related with family size. The...

Little research exists on the historical relationship between BMI variation, wealth, and inequality. This study finds that 19th century US black and white BMIs were distributed symmetrically; neither wasting nor obesity was common. Nineteenth century BMI values were also greater for blacks than...
