(Phys.org) —Comparisons between the stock market floor and a zoo are not far from the mark, according to a new study published today in the journal Proceedings of the National Academy of Sciences (PNAS).
here is the paper in PNAS:
Though I have to say that in humans it may not be the case that the rich will risk less. I think the analogy of water/thirst with economical wealth is a weak one. In fact one may argue that richer you are, it is more likely to risk. The construct of our economical system is such that the more you put in, there likelihood to gain more is higher. Also, it is true that risking is not always profitable, but those who take extreme risks are the ones that jump across the scales of wealth.
