According to gwern,
In his autobiography, Alan Greenspan says he did exactly that: he hired underpriced women and made money from not being sexist. Similarly, I have read of a company or agency which does the same thing in highly sexist South Korea, and for other forms of discrimination, we have companies specializing in hiring discriminated-against people on the autism spectrum and making money off the difference. If you want to prove a market isn’t efficient, simply reliably make excess risk-adjused returns…
Isn't this practice just as reprehensibly sexist? Hiring people that you know are just as good and paying them less for no good reason?
LW readers have unusual views on many subjects. Efficient Market Hypothesis notwithstanding, many of these are probably alien to most people in finance. So it's plausible they might have implications that are not yet fully integrated into current asset prices. And if you rightfully believe something that most people do not believe, you should be able to make money off that.
Here's an example for a different group. Feminists believe that women are paid less than men for no good economic reason. If this is the case, feminists should invest in companies that hire many women, and short those which hire few women, to take advantage of the cheaper labour costs. And I can think of examples for groups like Socialists, Neoreactionaries, etc. - cases where their positive beliefs have strong implications for economic predictions. But I struggle to think of such ones for LessWrong, which is why I am asking you. Can you think of any unusual LW-type beliefs that have strong economic implications (say over the next 1-3 years)?
Wei Dai has previously commented on a similar phenomena, but I'm interested in a wider class of phenomena.
