We introduce a novel incentive program aimed at decreasing school absenteeism based on the effect of voluntary promises in motivating desirable behaviour. In contrast to a standard program, in which students receive a reward conditional on having achieved a school attendance rate of at least 90...

Trends in BMI values are estimated by centiles of the US adult population by birth cohorts 1886-1986 stratified by ethnicity. The highest centile increased by some 18 to 22 units in the course of the century while the lowest ones increased by merely 1 to 3 units. Hence, the BMI distribution...

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...
