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. While we are not able to explore mechanisms in depth, our evidence points to a limited role played by increased investments in early childhood health or selection into childbearing in response to HYV adoption.
我们采用差分法来证明在印度，推广高产品种（HYV）降低了婴儿死亡率。即使比较同一位母亲的孩子，这种效果依然存在。高产品种的采用对农村儿童、男孩和低种姓儿童的死亡率影响更大。虽然我们无法深入探讨其中的机制，但我们的证据表明，增加对儿童早期健康的投资或因采用高产品种而选择生育的作用有限。
