Much has been written about 19th century African American and white statures and body mass index values. However, little is known about their physical activity and calories required to sustain height and weight. This paper considers two alternative measures for biological conditions that address...

Work requirements can make it easier to screen the poor from the non-poor.They can also affect future poverty by changing the poors' incentive to invest in their income capacity. The novelty of our study is the focus on long term poverty. We find that the argument for using work requirements as...
