This study assesses both the demand for and effectiveness of an index insurance product designed to help smallholder farmers in Bangladesh manage crop production risk during the monsoon season. Villages were randomized into either an insurance treatment or a comparison group, and discounts and rebates were randomly allocated across treatment villages to encourage insurance take-up and to allow for the estimation of the price-elasticity of insurance demand. Among those offered insurance, we find demand to be fairly price elastic, with discounts significantly more successful in stimulating demand than rebates. Purchasing insurance yields both risk management effects as well as income effects on agricultural production practices. The risk management effects lead to an expansion of cultivated area with concomitant increases in agricultural input expenditures during the monsoon season. The income effects lead to more intensive rice production during the subsequent dry season, with more intensive use of both irrigation and fertilizers, resulting in higher yields and higher total rice production.
本研究评估了一种指数保险产品的需求及其有效性,该产品旨在帮助孟加拉国的小农户应对季风季节的作物生产风险。村庄被随机分为保险处理组或对照组,折扣和回扣在处理组村庄中随机分配,以鼓励购买保险,并估计保险需求的价格弹性。在那些被提供保险的人中,我们发现需求对价格相当有弹性,折扣在刺激需求方面比回扣显著更成功。购买保险对农业生产实践既有风险管理效应,也有收入效应。风险管理效应导致种植面积扩大,同时在季风季节农业投入支出增加。收入效应导致在随后的旱季水稻生产更加集约化,灌溉和化肥的使用更加密集,从而提高产量和水稻总产量。
