“Saving lives with cooking gas? Unintended effects of targeted LPG subsidies in Peru”

Abstract: Gas stoves are promoted as clean cooking technologies in developing countries despite the fact that they emit pollutants which are hazardous, in particular for children. I study a nationwide gas stove program which aims to convert Peruvian households from wood-fuel cooking to liquefied petroleum gas (LPG) cooking. Using 16 waves of Peru’s Demographic and Health Survey, I show that infant mortality increases by 15% on average as a result of the intervention. Subsidizing LPG also causes a higher incidence of symptoms of acute respiratory infections in under-5 children and of moderate or severe anemia among adult women. I provide suggestive evidence that these health impacts are due to an increase in total exposure to air pollutants and to unanticipated behavioral effects of the intervention.
