This study examines the impacts of rainfall shocks on child health in Vietnam. It uses Young Lives data matched with province level climate data covering the period 1970–2014.

This paper identifies and confirms a third mechanism: shocks impacting on parents’ mental health which, in turn, reduce children's physical health. We find that one unit increase in parental mental health caused by rainfall shocks will increase the probability of a child being underweight by 0.976. Using an instrumental variable strategy, we can interpret these results as causal. We ..
