The choice to breastfeed rather than formula-feed an infant as well as the duration of doing so has been scrutinized in more recent times. Yet, key identification issues remain to be resolved, including the array of possible child development benefits, the optimal intensity of breastfeeding...

This paper examines variations in stature and the Body Mass Index (BMI) across space for the United States in 1917/18, using published data on the measurement of approximately 890,000 recruits for the American Army for World War I. It also connects those anthropometric measurements with an index...

This paper examines the impact of potential fetal malnutrition on the academic proficiency of Muslim students in Denmark. We account for the endogeneity of fetal malnutrition by using the exposure to the month of Ramadan during time in utero as a natural experiment, under the assumption that...

Worldwide, extreme poverty is often concentrated in spaces where people and property are not safe enough to sustain effective markets, and where development assistance is dangerous – and might even induce violence. Expanding governance by coercively taking control of territory may enable...

The decline in the physical stature of the American population for more than a generation beginning with the birth cohorts of the early 1830s was brought about by a diminution in nutritional intake in spite of robust growth in average incomes.

Medical research indicates that breastfeeding suppresses post-natal fertility. We model the implications for breastfeeding decisions and test the model's predictions using survey data from India. First, we find that breastfeeding increases with birth order, since mothers near or beyond their...

We use a randomized controlled trial to study the effect of large income changes, through unconditional cash transfers, on the food share of expenditures and consumption of calories among poor households in rural Kenya. Our preferred estimate of the food elasticity following USD 709 transfers is...

This paper tests whether income affects the body weight and clinical weight classification of elderly Americans using a natural experiment that led otherwise identical retirees to receive significantly different Social Security payments based on their year of birth. We exploit this natural...
