We evaluate the association between the variations in income and wealth, (both aggregate and split between real estate and financial wealth), and self-perceived health in Spain using a longitudinal sample of individuals before and after the financial crisis. We estimated generalized linear mixed models, with a binomial response and a logistic link, for four waves of the Spanish Survey of Household Finances (two before and two after the crisis), adjusting for variables at the family and individual levels. We also controlled for familial and individual heterogeneity and for temporal trends. While an increase in wealth greatly increases the probability of younger individuals reporting better health, this is not the case for older individuals. Decreases in gross wealth are associated with decreases in the probability of declaring good/very good health only in families whose reference person is over 44 years old. We conclude that: (i) not just income but net wealth effects impact on the consequences of income fluctuations on consumption and health assessed, (ii) the composition of individuals' net wealth may also matter, since they are differently affected by the shocks in the economic crisis, (iii) age plays a significant role and, finally, (iv) individual reactions in terms of consumption and savings, given any level of income and wealth, according to the risk aversions for precautionary idiosyncratic motives, may also need to be considered in order to complete the picture.
我们使用西班牙家庭金融调查(在金融危机之前和之后进行了两次)的纵向个人样本,评估了收入和财富(包括房地产和金融财富的总和以及两者之间的划分)的变化与自我感知健康之间的关联。我们使用广义线性混合模型,采用二项式响应和逻辑链接,对西班牙家庭金融调查的四个波次进行了估计,对家庭和个人层面的变量进行了调整。我们还控制了家庭和个人异质性以及时间趋势。虽然财富的增加大大增加了年轻个体报告健康状况良好的可能性,但对于年长个体而言并非如此。总财富的减少与报告健康状况良好/非常好的概率下降仅在参考人年龄超过 44 岁的家庭中相关。我们得出的结论是:(i)不仅仅是收入,净财富效应也会影响收入波动对消费和健康的影响;(ii)个人净财富的构成也可能很重要,因为他们受到经济危机冲击的影响不同;(iii)年龄起着重要作用;最后,(iv)考虑到任何收入和财富水平下出于预防性特殊动机的风险厌恶,个体在消费和储蓄方面的反应也可能需要考虑,以完整描述问题。
