Experiments and field studies on gambling and betting show that women on average are more risk averse than men. My anecdotal evidence as a father of two young ladies age 6 and 5 proofs quite to the contrary that female do behave hazardously on playgrounds. However, as an economist, I have no reason to doubt the empirical results.
But I doubt, indeed, that reversing reality in the sense of replacing “male dominance” in finance by “female dominance” would make the world a better, or the financial industry a safer place. It would merely create another type of “unbalanced reality” with the same tendency to herding behaviour.
