风险、时间与饮食质量：来自一般人群调查的证据
Risk, time, and diet quality: Evidence from a general population survey
摘要
This paper explores the relationships between overall diet quality and attitudes toward risk and time using a general population survey. We combine a food frequency questionnaire and a choice-based preference module to elicit individual risk and time preferences. The online questionnaire was administered to a socioeconomic panel representative of the French population. We show that risk and time preferences are associated with individual heterogeneity in key aspects of diet quality, a result that holds across a wide range of robustness checks. Using a hierarchical Bayes framework, we jointly estimate individual risk aversion and impatience parameters and show that associations hold for both model-free and structural estimates of risk and time preferences. We further show that these associations account for a substantial share of the heterogeneity in dietary outcomes beyond sociodemographic controls. Risk and time preferences contribute to both the income–diet-quality and education–diet-quality gradients, but in opposite directions, resulting in a limited net contribution to explaining socioeconomic inequalities in diet quality.
中文摘要
本文利用一项一般人群调查，探讨了整体饮食质量与风险和时间态度之间的关系。我们结合食物频率问卷和基于选择的偏好模块，以引出个体的风险偏好和时间偏好。该在线问卷面向一个具有法国人口代表性的社会经济小组发放。我们发现，风险偏好和时间偏好与饮食质量关键方面的个体异质性相关，这一结果在广泛的稳健性检验中均成立。采用分层贝叶斯框架，我们联合估计了个体风险厌恶和不耐烦参数，并表明这些关联对风险偏好和时间偏好的无模型估计和结构估计均成立。我们进一步表明，这些关联在超越社会人口控制变量之外，解释了饮食结果异质性的相当大一部分。风险偏好和时间偏好对收入—饮食质量和教育—饮食质量梯度均有贡献，但方向相反，导致其在解释饮食质量社会经济不平等方面的净贡献有限。
