Marriages between blood relatives – also known as consanguineous unions – are widespread in North Africa, Central and West Asia and most parts of South Asia. Researchers have suggested that consanguinity has adverse effects on child development, but assessing its impact is not...

Inequalities in the opportunity to obtain a good education in low-income countries are widely understood to be related to household resources and schooling quality. Yet, to date, most researchers have investigated the contributions of these two factors separately. This paper considers them...

Research from the United States shows that gaps in early cognitive and non-cognitive ability appear early in the life cycle. Little is known about this important question for developing countries. This paper provides new evidence of sharp differences in cognitive development by socioeconomic...

The poor state of child health in India has generated a number of puzzles that have received attention in the literature. A recent focus on birth order has produced contradictory results. Coffey and Spears (2019) document an early-life survival advantage in India accruing to later birth orders,...

It is well-established that (1) there is a large genetic component to mental health, and (2) higher schooling attainment is associated with better mental health. Given these two observations, we test the hypothesis that schooling may attenuate the genetic predisposition to poor mental health....

Food coma, also known as postprandial somnolence, is a commonly cited reason for experiencing reduced alertness during mid-afternoon worldwide. By using exogenous variation in the timing of tests and, hence, by extension, plausibly exogenous variation in the temporal distance between an...

We revisit the much-investigated relationship between schooling and health, focusing on cognitive abilities at older ages using the Harmonized Cognition Assessment Protocol in the Health & Retirement Study. To address endogeneity concerns, we employ a nonparametric partial identification...

Many low- and middle-income countries have introduced Public Works Programmes (PWPs) to fight poverty. PWPs provide temporary cash-for-work opportunities to boost poor households' incomes and to provide better infrastructure to local communities. While PWPs do not target children directly, the...

While the long-term consequences of early stunting on educational attainment and on school achievement tests are well-known, there is scarce evidence about the specific mechanisms through which early stunting leads to poorer educational outcomes, especially in LMIC contexts. We use unique data...

Global warming is changing precipitation patterns, harming communities strongly tied to agricultural production, particularly in low-and-middle income countries (LMICs). Whilst the long-term effects of being exposed to rainfall shocks early in life on school achievement tests are...
