    Abstract

    Even if a patient's access to health information has been enhanced, a patient still doesn't have enough ability to utilize it. Therefore, a doctor's effort to sincerely communicate with a patient might affect the patient's use of medical care. This paper builds up the empirical model and found the effect of a doctor's effort on patient's medical care use was significant and according to the ex-ante health status of a patient, a doctor's effort influenced a patient's medical care use in different way.
