【主题】Assessing Individual’s Response to the Nonlinear Health Insurance Plan: Evidence From A Hawkes Process Framework
【摘要】In this paper, a Hawkes process is proposed to study an individual's responsiveness to the outpatient utilization under a nonlinear health insurance contract. For a given individual, each doctor visit record is represented as a point in a Hawkes process. When measuring the responsiveness, we adopt the episode-varying shadow price instead of a constant spot price or the expected end-of-year price. Using the RAND Health Insurance Experiment data, we found that individuals do understand the price incentive of a nonlinear contract. Our model can also describe the cluster patterns of outpatient utilization under different insurance plans. Comparing to a free insurance plan, a canonical individual would have fewer doctor visits in a cluster, and the cluster number also shrinks.
