This is likely the basis for the idiom that an informed consumer is a better consumer. The result is that a market in which there is asymmetric information with respect to quality shows characteristics similar to those described by Gresham’s Law: The cost of dishonesty, therefore, lies not only in the amount by which the purchaser is cheated; the cost also must include the loss incurred from driving legitimate business out of existence.
