Their research suggests that the market already effectively prevents the form of price discrimination targeted by legislation--so-called third degree price discrimination. On balance, third degree price discrimination disfavors men, but only by 0.05%. Whereas so-called second degree price discrimination disfavors women by 11%. However, in second degree price discrimination there are often actual, substantive differences in the product, for example additional ingredients like moisturizers, so the "discrimination" is at least partly rooted in costs and preferences. There are still areas where women see problematic price discrimination, such as at car dealerships. (First degree price discrimination?) The crux of their argument is that the best way to deal with that, if at all, is through more transparent pricing as according to their research women are capable (en masse) of forcing fairer pricing when they can more easily comparison shop.
