Health anxiety and patient behavior

Abstract

Economic models of patient decision-making emphasize the costs of getting medical attention and the improved physical health that results from it. This note builds a model of patient decision-making when fears or anxiety about the future—captured as beliefs about next period’s state of health—also enter the patient’s utility function. Anxiety can lead the patient to avoid doctor’s visits or other easily available information about her health. However, this avoidance cannot take any form: she will never avoid the doctor with small problems, and under regularity conditions she will never go to a bad doctor to limit the information received.
