A few weeks ago Bruce Schneier discovered a classic economics paper, “The Market for Lemons”. The paper describes the behavior of markets where sellers have detailed information about the products, particularly the quality of the products, that buyers do not have. It uses the example of used cars.

In these markets, the price buyers are willing to pay is defined by average quality of good. Buyers lack information, so can only assume they are going to get a product of average value. Unfortunately, this lower price drives the best products out of the market, because sellers (who know they have the best goods) won’t accept that price. When the best goods are removed from the market, the average quality drops, the price drops, and the next best goods are removed from the market. The conclusion is that in these markets quality falls until it matches the amount of information that buyers have.
