Standards vs. labels with imperfect competition and asymmetric information

I demonstrate that providing information about product quality is not necessarily the best way to address asymmetric information problems when markets are imperfectly competitive. In a vertical differentiation model I show that a Minimum Quality Standard, which retains asymmetric information, generates more welfare than a label, which provides full information.
