An entrepreneurial system would encourage competition, particularly through prepaid plans, which allow consumers to shop for the best price. It would allow customers to choose their doctors and hospitals. It would measure and publicize results-customer surveys, medical outcomes, and the like-so customers could choose based not only on price but on quality. It would create strong incentives for preventive care, in part by encouraging prepaid arrangements, under which insurers benefit by preventing disease, and in prat by encouraging preventive behavior (perhaps by making activities like smoking and drinking more expensive)
