The Market for Lemons
“Successful investing is about managing risk, not avoiding it” – Benjamin Graham. This phenomenon describes the adverse selection / knowledge asymmetry between buyers and sellers in, for example, the used car market. As prices (or in this case, standards) fall, the only willing sellers at a given price will be those that have “lemons” (defective goods) to sell. Thus, the average quality of goods available in the market gradually falls, leaving only poor quality goods left, which is a form of Gresham’s Law.
