"The altruistic giving of organs might decline with an open market, since the incentive to give organs to a relative, friend or anyone else would be weaker when organs are readily available to buy. On the other hand, the altruistic giving of money to those in need of organs could increase to help them pay for the cost of organ transplants."
Paying for organs would lead to more transplants, the article maintains. "Initially, a market in the purchase and sale of organs would seem strange, and many might continue to consider that market "repugnant." Over time, however, the sale of organs would grow to be accepted, just as the voluntary military now has widespread support.""
