Easy-to-use and low-risk technologies, which require little investment and potentially provide health and environmental benefits, often have low adoption rates. Using a randomized experiment in urban Mali, we assess the impact of a training session in which information on an improved cookstove (ICS) is provided along with the opportunity to purchase the product at the market price. We find strong effects from our invitation to the session on ICS ownership and usage while no discernible effects on product knowledge or household welfare. We find that some diffusion occurs beyond the intervention and provide evidence on the role of social interaction, mostly through imitation

易于使用且风险低的技术需要很少的投资，并可能带来健康和环境效益，因此采用率通常很低。通过在马里市区进行的一项随机实验，我们评估了培训课程的影响，该课程提供了有关改进灶具（ICS）的信息以及以市场价格购买产品的机会。从我们对ICS所有权和使用率的会议的邀请中，我们发现了强大的影响，而对产品知识或家庭福利没有明显影响。我们发现，除了干预之外，还发生了一些扩散，并提供了关于社会互动作用的证据，主要是通过模仿
