Bequests and Informal Long-Term Care
研究了子女对年迈父母的非正式长期照护是否会影响父母给予的遗赠，发现照护决策显著增加获得遗赠的可能性和金额，且照护量相对于兄弟姐妹越多，分得遗赠比例越高，这种正向关系需要书面遗嘱作为契约。
Informal long-term caregiving for frail elderly individuals by their children may induce parents to compensate their children for their help. To test this hypothesis, I use the exit interview from the Health and Retirement Study (HRS). My results show that the decision to care for one's parents has a significant positive impact on the incidence and amount of bequests received. In addition, increasing the amount of care relative to one's siblings significantly increases the proportion of bequest within a family. Furthermore, I find that the positive nexus of caregiving and bequest requires a written will as a contract between the parent and the helping child.
