Social connections and tertiary health‐care utilization
利用印度公共三级医疗项目的行政数据，研究发现同村同种姓群体的首次就医弹性为0.046，住院支出弹性为0.035，且信息渠道是重要机制，对设计基于网络的医疗需求模型和干预有启示。
Abstract The use of tertiary health care by socially proximate peers helps individuals learn about program and treatment procedures, signals that using such care is socially appropriate, and could support the use of formal health care, all of which could increase program utilization. Using complete administrative claims data from a publicly financed tertiary care program in India, we estimate that the elasticity of first‐time claims with respect to claims by members of caste groups within the village is 0.046, with smaller effects of more socially distant individuals. The point elasticity of inpatient care expenditure with respect to claims filed by the same group in village peers in the previous quarter is 0.035. We find support for an information channel as peers increase awareness of the program and its features. Our findings have implications for the development of network‐based models to determine health‐care demand, as well as in use of network‐based targeting to boost tertiary health‐care utilization.
