粮食不安全仍然是肯尼亚的一个重大关切。人口中的弱势群体，如儿童、老年人、边缘化的少数民族和低收入家庭，受到粮食不安全的影响尤为严重。继森的开创性工作，审查暴露于粮食不安全在家庭一级使用他的“权利的方法”，本文估计家庭的脆弱性粮食不安全。反过来，对结果变量进行分解，以解释被归类为“边缘化”和“非边缘化”的家庭之间的粮食不安全差距。我们应用Oaxaca-Blinder分解方法来研究粮食不安全的脆弱性，特别是观察到的社会人口特征（禀赋）差异或这些特征的回报差异的贡献，在我们的背景下，与家庭附近的公共服务和基础设施差有关。结果表明，粮食不安全脆弱性的差异主要是由于教育、年龄和家庭收入等社会人口特征的差异。因此，在获得粮食和其他生产性资源方面，通过投资于目标家庭的特点来实现公平的政策，可以有效地解决粮食不安全问题。例如，政策制定者可以利用教育和社会保障方案，包括养老金损失风险保险计划，制定家庭包容性方案。
Food insecurity remains a vital concern in Kenya. Vulnerable members of the population, such as children, the elderly, marginalised ethnic minorities, and low-income households, are disproportionately affected by food insecurity. Following the pioneering work of Sen, which examined exposure to food insecurity at a household level using his "entitlement approach", this paper estimates households' vulnerability to food insecurity. In turn, the outcome variable is decomposed in order to explain the food insecurity gap between households classified as "marginalised" and "non-marginalised". We applied the Oaxaca-Blinder decomposition method to examine vulnerability to food insecurity and, in particular, contributions of observed differences in socio-demographic characteristics (endowments) or differences in the returns to these characteristics, which, in our context, is associated with poor public services and infrastructure in the vicinity of the household. The results indicated that differences in vulnerability to food insecurity were mainly attributable to observed differences in socio-demographic characteristics such as education, age, and household income. Therefore, policies seeking to attain equity by investment into targeted household characteristics in terms of access to food and other productive resources could effectively combat food insecurity. For example, policymakers could develop programs for household inclusiveness using education and social protection programs, including insurance schemes against risk of endowment loss.
