Information asymmetry in healthcare: "'Money is power in the marketplace,' Case said. 'Consumers will have more power because they'll be controlling more of the money.' Case also notes the problems caused by a lack of information in the health care marketplace. For example, he says, a consumer can go online and find a baseball signed by former pitcher Tommy John for sale, determine the reputation of the seller and easily compare prices. But someone needing so-called Tommy John surgery -- officially, ulnar collateral reconstruction, considered one of the major advances of sports medicine -- would be hard-pressed to find providers of that surgery and their track records."
