Economic Disability and Health Determinants of the Hazard of Nursing Home Entry
使用Cox比例风险模型，分析社区居住的老年残疾人在34个月内首次入住养老院的经济决定因素，发现财富显著降低入住风险，价格弹性为-0.7，且入住与家庭非正式照护者的机会成本正相关。
A Cox proportional hazards model was used to estimate economic determinants of the conditional probability of first nursing home entry during a 34-month period for a panel of disabled older persons who resided in the community at the initial survey. Allowing for death that competes with first entry and end-ofsurvey censoring produced the following results. Wealth significantly reduces the hazard of nursing home entry. The price elasticity of the hazard of nursing home entry is estimated to be -0.7. Also, nursing home entry is positively related to the opportunity cost of informal caregiver time faced by the family.
