Somewhat surprisingly, children seem to be less affected than the elderly, which shows that in spite of the higher short-term impact on young children, they manage to recover the best from early health issues caused by pollution. In particular, our result on the effects of pollution on lung capacity for children mitigates the apparently contradicting results from the two concurrent studies mentioned earlier. While Rosales and Triyana (2015) found significant effects of pollution on the lung capacity of young children that persist in the medium-run, Banerjee (2016) found no such effects in the long-run, which our study confirms. This is consistent with a recovery and catching up hypothesis. We are unable to analyze their other results, since lung capacity is the only common outcome between our study and theirs.
