In this paper, we use the variation across space and time in the expansion of natural gas infrastructure in Turkish provinces using data between 2001 and 2011. Our results indicate that the rate of increase in the use of natural gas has resulted in a significant reduction in the rate of infant mortality in Turkey. In particular, a one-percentage point increase in the rate of subscriptions to natural gas services would cause the infant mortality rate to decline by 4 percent, which could result in 348 infant lives saved in 2011 alone. These results are robust to a large number of specifications.
The authors outline two ways through which the effect may occur:
