As improved cookstove programs increase in popularity, policy makers need accurate estimates of their constituents’ willingness to pay for the stoves. Knowing which socioeconomic factors affect willingness to pay will allow program planners to price and target the stoves effectively. This study elicits the willingness to pay of 300 rural Malawians in Dedza District for two types of stove and explores the determinant socioeconomic factors. Respondents were willing to pay a median price of 7 USD for a clay stove and 9 USD for a rocket stove. In the clay stove regression model, willingness to pay is positively correlated with dietary diversity and negatively correlated with fuel expenditure. In the rocket stove regression model, willingness to pay is positively correlated with net household income and dietary diversity, and negatively correlated with higher incidence of cooking-related ailments. A literature review reveals that because of the discrepancy between short-term and long-term impacts of improved cookstove adoption, the focus of stove programs should be sustained, proper stove use by adopters, not just dissemination. Positive impact estimates are inflated when only short-term adoption data and laboratory fuel test results are used; more long-term impact evaluations are needed. Further, the study of socioeconomic determinants of stove adoption alone is inadequate for a self-sustaining, unsubsidized improved cookstove market. Choice elicitation experiment studies on product-specific attributes, that is stove characteristics, should complement socioeconomic findings to determine what is most desired by the target market.
