The present paper evaluates the effects of the use of improved cookstoves (ICSs) on household fuel expenditure in Southern Haiti. It takes advantage of the fact that approximately 80 households received ICSs, a novel technology, in the aftermath of the 2010 Haitian earthquake. Survey work in 2014 permits a comparison of fuel expenditures between ICS-using households and non-using households. The effect of ICS use on fuel expenditure is estimated using a simple t-test and propensity score matching methods. Ultimately, understanding the effect of ICS use on fuel expenditures will help promoters of ICSs to improve their marketing plans and increase adoption.
