Only the second to last link seems to be in the same category of this post (it talks about risk-aversion in investments more generally, while I'm talking more specifically about startups here).
My previous post was about the likelihood of startup success. This post takes chances at success as a given, and asks the question of whether those chances justify an effective altruist starting a startup.
See http://80000hours.org/blog/12-salary-or-startup-how-do-gooders-can-gain-more-from-risky-careers.
The expected value of risky careers like startups if often much higher than less risky careers. However, this is more than offset by peoples' risk-aversiveness due to diminishing marginal utility. But... if you're an effective altruist, the money you make doesn't have diminishing marginal value. So... it seems that risky careers like startups are a good choice, if you're trying to maximize your positive impact.
What do you guys think?
