Ellis and McGuire: Optimal Payment Scheme<br />

β ∗ = 2 − 1 θ<br />

Optimal degree of incentive pay is increasing in θ.<br />

Intuition: if doctor is selfish (high θ), reimburse him for costs of<br />

provision so that he doesn’t under-provide service to patients.<br />

But if he is benevolent, reduce the amount he gets paid for provision.<br />

He will naturally get benefits from taking care of them and will<br />

over-provide if he is paid for it too.<br />

HMOs desirable if healthcare providers are benevolent; FFS<br />

reimbursement if they are profit-seeking.<br />
