Abstract

Some research suggests women are more likely to allocate additional resources to their children than are men. This perception has influenced policies such as in-kind food transfer programs and cash transfer programs, which often target women recipients. We assess whether targeting in-kind rice transfers to female versus male adult household members has a differential impact on children's short-run nutritional status. We estimate the impacts of transfers of edible rice and rice seeds, randomly allocated to female or male adults, on three anthropometric indicators: BMI-for-age, arm-muscle area, and triceps skinfold thickness. The trial includes 481 children aged 3-11 years in a horticultural-foraging society of native Amazonians in Bolivia. On average, the gender of the transfer recipient does not influence child anthropometric dimensions, possibly due to norms of cooperation and sharing within and between households. We find limited evidence of heterogeneity in impacts. Transfers to women help children who were growth stunted at baseline to partially catch-up to their better-nourished age-sex peers and help boys (but not girls) and children in higher-income households increase their BMI-for-age. The results of this research point to the importance of considering cultural context in determining if allocating food transfers according to gender are most effective.

摘要

一些研究表明,与男性相比,女性更有可能为子女分配额外资源。这种观念影响了诸如实物粮食转移计划和现金转移计划等政策,这些政策通常以女性受助者为目标。我们评估了将实物大米转移目标设定为成年女性家庭成员而非成年男性家庭成员,是否会对儿童的短期营养状况产生不同影响。我们估计了随机分配给成年女性或成年男性的食用大米和稻种转移对三个身体测量指标的影响:年龄别体重指数、手臂肌肉面积和三头肌皮褶厚度。该试验涵盖了玻利维亚一个以园艺采集为生的本土亚马逊人社会中的481名3至11岁儿童。平均而言,转移接受者的性别不会影响儿童的身体测量维度,这可能是由于家庭内部和家庭之间的合作与分享规范所致。我们发现影响存在异质性的证据有限。向女性的转移帮助了基线时发育迟缓的儿童部分赶上营养状况更好的同龄儿童,并帮助男孩(而非女孩)以及高收入家庭的儿童提高了年龄别体重指数。这项研究的结果表明,在确定按性别分配粮食转移是否最有效时,考虑文化背景非常重要。
