Cynical: Female Economists are somewhat less likely to have been bought lock stock and barrel by conservative interests. Because, being conservative, the people corrupting the entire discipline of economics tend to snub, overlook, belittle, and otherwise just flat out antagonize professional women.
Economists are not conservative.
In this study, 47 percent of the students classified themselves as liberal, 24 percent as moderate, 16 percent as conservative and 6 percent as radical. (Six percent stated that politics were unimportant to them.)

Can this be reasonably explained by self-interest? Female and male economists' views are probably coloured by gender solidarity. Government jobs may be more likeable to women than men because of their recorded greater risk aversion. Regardless of the reason government jobs are more important for women than for men. Also in the US where the study was done middle class white women benefit quit a bit from affirmative action in government hiring.
Politics is the mind-killer probably does play a role in explaining the difference.
First two points are somewhat congruent with stereotypes. Anyone who has run into the frequent iSteve commenter "Whiskey" will probably note that the third point indicates women may not hate hate HATE lower and middle class beta males in this case.
This seems plausible since politics is about applause lights after all, the tribes are what matters not the particular shape of their attire. But might value differences still be behind the gender difference? Maybe some failed utopias I recall reading aren't really failed.
Somehow I think this does not include ideological diversity.
No mystery here. (^_^)
