reciprocal altruism

a form of helping behavior that is sustained when one individual (A) helps another (B) and at some future time B helps A or A’s offspring. The requirements of reciprocal altruism are (a) that the participants are able to identify each other individually, (b) that they are able to remember past actions and who helped whom, (c) that the cost to the helper is less than the gain to the recipient, and (d) that there is a mechanism to protect against cheating. Game theory provides a theoretical system for understanding reciprocal altruism. See also altruism.

consumer-driven health care

consumer-driven health care

an approach to health care cost containment that lets consumers decide how to spend dollars earmarked for health and mental health care. Instead of providing insurance with a low deductible for employees, an employer might fund a high-deductible insurance policy and a tax-advantaged account such as a health savings account, a health reimbursement account, or another medical payment product that consumers could use to help meet the high deductible. Because consumers can shop for and choose the doctors that they want to see and the procedures that they want done, this type of care is posited to bring competition to the health services market and more control to consumers, although the benefits and effectiveness of this arrangement are being debated.
