讲座简介

cost sharing is central to health insurance design to achieve the seemingly conflicting objectives of controlling costs and ensuring access to care. we investigate how to achieve both objectives by leveraging a pilot insurance program in rural china that lowered prescription drug cost sharing for two chronic diseases---hypertension and diabetes. exploiting a unique administrative medical dataset, we find the program increased the use of outpatient care and sharply reduced inpatient admissions, a phenomenon termed the hospitalization offset, and achieved a substantial saving of total medical expenditure. three findings are worth noting. first, patients with the highest prior spending were most responsive to the change of cost sharing and contributed the most to the net saving of expenditure. second, the hospitalization offset was achieved by stimulating regular outpatient visits and improving patient health rather than pure substitution between inpatient and outpatient services. third, the information and salience effect of the program contributed importantly to the hospitalization offset. our findings have important implications for the value-based insurance design.
