Afternoon Must-Read: Steve Randy Waldmann: The Information Asymmetry Industry

Steve Randy Waldmann: The Asymmetric Informtion Industries: "Government, health care, education, and finance....

Information asymmetries are unusually difficult to resolve in these industries. A substantial fraction of people who buy a low quality house, car, or stereo eventually come to notice that. This makes it possible for new purchasers of these goods to manage their information problem by researching others’ experience and seller reputations. But in the four industries I’ve described, even after we have purchased services, we are often unable to evaluate their quality....

Note that these problems are not just a matter of bad actors. These industries face intrinsically difficult information problems. We can condemn a used car salesman who finesses odometers, but we can’t condemn the surgeon who thinks he is a god.... Absent reliable markers of quality, we imagine that unreliable self-evaluations are probably better than nothing.... As these are fields in which providers themselves can’t reliably evaluate the quality of the services provided, the rest of us will have a very hard time distinguishing between corrupt practices and natural variability....

We need the “information asymmetry industry”.... But we should acknowledge these are problematic industries for a capitalist economy and a democratic polity. Forecasts that they will dominate, or prescriptions that we should specialize in these sectors to exploit alleged comparative advantage, should be greeted unenthusiastically. I hope that Timothy Geithner takes note.
