Less is known about the impact of cancer on household assets and household financial portfolio during which cancer survivors face higher mortality risk. Economic theory predicts that cancer survivors would deplete their wealth in such a way that meets immediate financial needs for treatment and that hedges the risk of anticipated medical expenses associated with recurrence. Building upon this prediction, we examine long-term changes in household assets in response to cancer diagnosis among middle-aged and elderly Americans (age ≥ 50).
Using the 2000-2014 waves of the Health and Retirement Study, we estimated the household fixed effects regression that regresses household assets on time elapsed since cancer diagnosis (≤ 2 years, > 2 but ≤4 years, > 4 but ≤6 years, and > 6 but ≤8 years). Regression estimates were adjusted for demographic characteristics, general health condition, employment outcomes, and household economic attributes. Household assets were measured by total net worth as well as the amount of savings held in each asset category. The loss of household assets attributable to cancer was estimated to be $125,832 in 2015 dollars per household with a cancer patient. This change came from statistically significant reductions in investment assets, miscellaneous savings, real estate equity, and business equity, and increases in unsecured debt. We also found 17.2-28.0% increases in cash and cash-equivalent assets from + 2 years since diagnosis through the rest of the study periods. The accumulation of cash was observed for both the well-insured group (multiple coverages) and those with limited insurance (single coverage).
The results showed evidence of both asset depletion and precautionary accumulation of liquid assets among cancer survivors, which reduces risk exposure of household financial portfolio. Our findings highlighted that household asset is an important source of liquidity to finance cancer care and to absorb the expected expenditure risk associated with cancer recurrence. We also showed that health insurance provides limited coverage of health risks associated with cancer.
关于癌症对家庭资产和家庭金融投资组合的影响,人们了解较少,而癌症幸存者在此期间面临更高的死亡风险。经济理论预测,癌症幸存者会以满足治疗的即时财务需求以及对冲与复发相关的预期医疗费用风险的方式耗尽其财富。基于这一预测,我们研究了美国中年和老年人(年龄≥50岁)因癌症诊断导致的家庭资产长期变化。
利用2000 - 2014年健康与退休研究的数据,我们估计了家庭固定效应回归模型,该模型将家庭资产对癌症诊断后的时间(≤2年、>2但≤4年、>4但≤6年以及>6但≤8年)进行回归。回归估计针对人口特征、总体健康状况、就业情况和家庭经济属性进行了调整。家庭资产通过总净值以及各类资产中的储蓄金额来衡量。以2015年美元计算,每个有癌症患者的家庭因癌症导致的家庭资产损失估计为125,832美元。这种变化源于投资资产、杂项储蓄、房地产权益和商业权益的显著减少,以及无担保债务的增加。我们还发现,从诊断后 + 2年到研究剩余期间,现金及现金等价物资产增加了17.2% - 28.0%。在保险充足的群体(多重保险)和保险有限的群体(单一保险)中均观察到了现金的积累。
结果显示癌症幸存者存在资产耗尽和流动资产预防性积累的证据,这降低了家庭金融投资组合的风险敞口。我们的研究结果突出表明,家庭资产是为癌症治疗融资以及吸收与癌症复发相关的预期支出风险的重要流动性来源。我们还表明,健康保险对与癌症相关的健康风险覆盖有限。
