5月25日中午，由经济学院能源经济系主办的能源经济研讨会（Energy Economics Seminar）第七十期会议在经济学院明德主楼623会议室举行。来自瑞典哥德堡大学Yonas Alem先生进行了题为“Liquidity constraint, LPG stoves and charcoal consumption: a randomized controlled trial in Tanzania ”的学术报告。

   在本次演讲中，Ynoas Alem先生向我们介绍了他关于坦桑尼亚城镇家庭能源使用情况的调查。他设计了一个随机对照试验，研究液化石油气等能源的利用对木炭使用的影响。结果表明，采用液化石油气炉灶可以减少47.5%的木炭使用量；与提供贷款相比，提供炉灶购买的补贴会在更大程度上减少木炭的使用（54%）。报告强调了放松家庭的金融约束和提高获得信贷能力的重要性，鼓励城市家庭转向清洁能源，并节省剩余的森林资源。

   能源经济研讨会由中国人民大学经济学院能源经济系定期推出，旨在为研究能源经济问题的学者提供一个交流的平台，以促进我国能源经济教学研究水平的提高。
