The design of the health care system involves issues of information at several points. The potential users (patients) are better informed about their own state of health and lifestyle than insurance companies. The health providers (doctors and hospitals) know more about what patients need than do either the patients themselves or the insurance companies. Providers also know more about their own skills and efforts. Insurance companies have statistical information about outcomes of treatments and surgical procedures from past records. The drug companies know more about the easy of drugs than do others. As is usual, the parties have different interests, so they do not have a natural inclination to share their information fully or accurately with others.
