妇女赋权和食物消费：来自坦桑尼亚女性户主家庭的证据

doi:10.1016/j.jia.2023.12.005

摘要/Abstract

摘要： 尽管越来越多的人认识到女性在家庭中的作用，并且在撒哈拉以南非洲开展了相应的赋权计划，但鲜有研究深入探讨女性赋权家庭与食物消费之间的关系。本文使用坦桑尼亚最近 (2017/18) 的全国家庭调查数据，考察了女性赋权对家庭食物消费的影响。我们首先使用描述性统计和倾向得分匹配法比较了女性户主家庭和男性户主家庭在八种食物类别中的差异。此外，我们采用两阶段LES-AIDS模型来估计两类家庭的收入和价格弹性。结果显示，女性户主家庭比男性户主家庭消费更多的面包和谷物、鱼、油和脂肪、蔬菜和糖、果酱、蜂蜜、巧克力和糖果。此外，与男性户主家庭相比，女性户主家庭对所有食品类别的需求收入弹性明显更高，在肉类、鱼类、油脂和糖、果酱、蜂蜜、巧克力和糖果方面的价格弹性也高于男性户主家庭。

Abstract:

Despite the growing recognition of women’s increasing role in the household and corresponding empowerment programs in sub-Saharan Africa, intensive research on the relationship between women’s influence and household food consumption is minimal. Using the most recent (2017–2018) national household survey data from Tanzania, this study examined the influence of women’s empowerment on household food consumption. First, we compared the monthly consumption of eight food categories between female-headed households (FHHs) and male-headed households (MHHs) using both descriptive statistics and the propensity score matching (PSM) method. Furthermore, we adopted the two-stage Linear Expenditure System and Almost Ideal Demand System model (LES-AIDS) to estimate income and price elasticities for the two household types. The results show that FHHs consume bread and cereals, fish, oils and fats, vegetables, and confectionery (sugar, jam, honey, chocolate, etc.) more than MHHs. Moreover, FHHs have a significantly higher income elasticity of demand for all food groups than MHHs. They are also more price elastic than MHHs in meat, fish, oils, fats, sugar, jam, honey, chocolate, etc.
