Talking money is definitely better than other types of persuasion, especially when it comes to companies. Having said that, I wouldn't put too much confidence in the articles you posted; the effects in the first one are tiny, and for one year only, and the beginning of the second one is ripe with sexist stereotypes (I didn't bother to read the whole one). Also, as with all economic/psychological research, the results are to be trusted only if they can be demonstrated over a very long period of time, by multiple researchers (and even then it's not of equal validity as a controlled scientific experiment). Having said that, I don't necessarily reject your hypothesis; I'm sure that people will be putting money to it, and if it's true, someone will be reaping profit.
