Despite its evident importance relatively little is known about links between Body Mass Index (BMI) and participation in workfare programs, particularly in India. Using a unique data set for the Indian state of Rajasthan for 2009-10, this paper attempts to fill this void and examines the association between BMI and participation in, duration of employment in and earnings from employment in NREGs. Thus we go beyond the scope of the extant literature and model these links for both male and female workers with varied social and economic backgrounds. Further, we permit non-linearities in some impacts and allow for mutual endogenity, say, between BMI and earnings. To the best of our knowledge this is the first paper to examine this range of issues.
