Incentivicing doctors to take the costs of treatment into account in their prescription decision could lead to lower health care expenditures and higher welfare. This paper shows that also the opposite effects can result. The reason is a misalignment of doctor and patient incentives: Because of health insurance, the patient does not take the costs of treatment fully into account. This misalignment hampers communication between patient and doctor, e.g. the patient may overstate the intensity of symptoms. It is shown that cost incentives for doctors increase welfare if the doctor's examination technology is sufficiently good or (marginal) costs of treatment are high enough. Optimal health care systems should implement different degrees of cost incentives depending on type of disease and/or doctor.
