Jason Collins favorably reviews The Hour Between Dog and Wolf, a book by John Coates, who says that hormonal responses to success and failure serve to reinforce risk-taking and risk aversion. I note from the book description on Amazon:
Dr. John Coates identified a feedback loop between testosterone and success that dramatically lowers the fear of risk in men, especially younger men—significantly, the fear of risk is not reduced in women.
I count this as additional support for what I have said I would do if I were financial regulatory czar: change the gender of the CEO’s of the largest banks.
Your last sentence makes it sound as if you’d force CEOs to undergo gender reassignment surgery. I imagine that would cut down dramatically on the number of applicants for the position. Talk about pre-commitment! But it might reduce the number of banks that meet the definition of “large”, so perhaps worth a try.
