在许多发展中国家，农户营养不良仍然是一个严重问题，与饮食缺乏多样性有关。我们探讨性别差异可能会影响家庭的饮食多样性使用LSMS-ISA埃塞俄比亚面板数据集。利用农户框架，非线性面板模型估计允许未观察到的异质性和生产endoeconomy使用控制功能。我们使用分解技术，以确定不同的潜在来源的饮食多样性的性别差异的影响。我们的研究结果提供了证据的生产多样性和饮食多样性的食品品种评分（FVS）的显着性别效应。对于饮食多样性的其他指标，性别影响的证据较弱。分解结果表明，在控制了特征差异后，女性户主家庭处于饮食多样性劣势。生产多样性、价格和收入以及饮食多样性和生产多样性决策之间关系的性别差异似乎是主要驱动因素。研究结果还表明，女性的偏好更倾向于确保家庭饮食的多样性。我们的证据还表明，饮食多样性中性别劣势的一个关键驱动因素与食物是来自家庭自己生产还是市场有关。这意味着，观察到的对饮食多样性的负面性别影响的一部分可能源于全年销售和储存自家产品的差异。
Malnutrition in farm households remains a significant problem in many developing countries and is linked to a lack of diversity in diets. We explore how gender differences might affect household dietary diversity using the LSMS-ISA Ethiopia panel dataset. Drawing on a farm household framework, nonlinear panel models are estimated allowing for unobserved heterogeneity and production endogeneity using a control function. We use decomposition techniques to identify the impact of different potential sources of gender difference in dietary diversity. Our results provide evidence of significant gender effects in production diversity and in dietary diversity using the food variety score (FVS). For other indicators of dietary diversity, the evidence of gender effects is weaker. The decomposition results suggest that, after controlling for differences in characteristics, female-headed households are at a dietary diversity disadvantage. Gender differences in the relationship between production diversity, price and income and dietary diversity and the production diversity decisions appear to be the main drivers. The results also suggest that female preferences are more orientated towards ensuring greater dietary diversity in the household. Our evidence also suggests that a key driver of gender disadvantage in dietary diversity is related to whether food is sourced from the household's own production or the market. This implies that part of the observed negative gender impact on dietary diversity may stem from differences in marketing and storage of own production through the year.
