Impact of improved cookstoves on women’s and child health in low and middle income countries: a systematic review and meta-analysis

“…No (quasi-)experimental studies assessed the impact of improved cookstoves on preterm birth or COPD among women. One study described a trend towards reduction in ‘respiratory system disease’ among women responsible for cooking who were allocated an improved cookstove: RR 0.51 (95% CI not reported, P=0.07) 23. This was defined as cough, wheezing and/or difficulty breathing, and may in part reflect COPD.…”

A health intervention or a kitchen appliance? Household costs and benefits of a cleaner burning biomass-fuelled cookstove in Malawi

“…Shadow pricing has been debated in economic evaluations of cookstove interventions (Bensch and Peters, 2015, García-Frapolli et al., 2010). Because rural populations have limited access to labour markets, and are instead involved largely in agricultural work, it is difficult to determine wages or time spent on income generating activities.…”

“…It is notoriously difficult to determine time usage and shadow prices (García-Frapolli et al., 2010, Bensch and Peters, 2015). Time savings were therefore based on reported differences prior to and after use of the Philips cookstove.…”

“…The first, as used in Bensch and Peters (2015), assumes that time saved cannot be converted to income generation. As time saved would be used only on domestic activities, and not income generation, this method does not result in a monetary benefit for time saved.…”

“…The health economics literature on adoption behaviour is an emerging area of research (see for example Bensch and Peters, 2015, Bensch et al., 2015, Dupas, 2011, Cohen and Dupas, 2010, Kremer and Miguel, 2007). In recent work, Dupas (2011) highlights the importance of including both the extensive margin of behaviour (mere adoption of a technology) as well as the intensive margin (how a technology is used and perceived) in evaluating the full effect of an intervention.…”
