So this is the second transgender libertarian-ish economist that we know of - Diedre McCloskey being the other. I think it is well known that men who go transgender often chose quite macho careers - the military, mountain climbers, engineering - the theory being that it is an over reaction in compensation to their inner desire to be feminine. As I think it would be fair to say that aggressively free market, libertarian ideas are the most "macho" form of economics there is (and God knows, its followers at Catallaxy routinely question the masculinity of males who they perceive as being of the Left), I think we can likely expect most transgender economists to come from that side of the fence. Davidson does seem to really like kilts; I'm now suspecting it's part of the softening up process for an announcement...
In any event, it changes nothing about my attitude towards Novak's work and her opinions: they're routinely doctrinaire, predictable, full of fetishistic adoration of free markets and complete disdain of government. Best ignored, as a male or female.
Update: I see McCloskey was saying much the same in 1999:
''There is this romantic idea among men that they are free agents in the marketplace, without any ties except to their individual selves,'' Ms. McCloskey said. ''While men think of themselves in metaphors of competition, there is an assumption among women that we are together, helping each other survive.'' She added: ''I was an aggressive, assertive male, and I felt comfortable. Now I am ashamed because that was so very macho.''
