Abstract
|
|
|
Purpose: this study investigates the effect of private health insurance on healthcare utilization.
Methodology: For the analysis, we employed the three level nested two part model.
Findings: the private health insurance adoption was associated with higher health care utilization. In particular, indemnity and fixed insurances adoption was associated with higher probability of outpatient visit, the number of outpatient visit and outpatient cost. While indemnity insurance adoption was associated with higher inpatient admission probability and inpatient days, fixed insurance adoption was associated only with higher inpatient admission probability.
Practical Implications: indemnity and fixed insurance adoption were related with the adverse selection as well as moral hazard.
