What Impedes Efficient Adoption of Products? Evidence from Randomized Sales Offers for Fuel-Efficient Cookstoves in Uganda
研究发现，结合免费试用、分期付款和退货选项的销售方案，能显著提高乌干达城市和农村地区节能炉灶的采用率，从4%-5%提升至46%-57%。
Consumersâ failure to adopt products with health and wellbeing benefits apparently far greater than their costs has consistentlychallenged the widespread use of health-improving technologies. A sales offer combining free trial, time payments, and the option of returning the product can overcome barriers such as liquidityconstraints and poor information about benefits and usability. We tested this sales offer (and alternatives) in an experiment with a fuel-efficient charcoal stove in urban Uganda and a fuel-efficient wood stove in rural Uganda. This offer dramatically increased uptakeâin urban Kampala, from 4 to 46%, and in rural Mbarara, from 5 to 57%.
