The Original Study

Numerous researchers have shown that indoor smoke inhalation, oftentimes from cooking air pollution, to be a significant negative health externality for developing world households (and especially children). This study examines the effects of reduced smoke technology adoption on the incidences of pneumonia in Guatemala through a random-controlled trial. Although the results are somewhat inconclusive, a significant reduction in the cases of severe infant pneumonia suggests the possibility of wood chimney stoves decreasing childhood mortality rates.
