Dust and Death: Evidence from the West African Harmattan.

Using two decades of data from 12 low-income countries in West Africa, we show that dust carried by trade winds increases infant and child mortality. Health investments respond to dust exposure, consistent with compensating behaviours. Despite these efforts, surviving children still exhibit negative health impacts.

The Green revolution and infant mortality in India.

We use a difference in differences approach to show that the adoption of High Yielding Varieties (HYV) reduced infant mortality in India. This holds even comparing children of the same mother. The effects of HVY adoption on mortality are larger for rural children, boys, and low-caste children.
