Le Guard-ian of the World's Coffers

Finally a woman ruling the IMF!! Why is the distribution of economists so skewed in favour of males? I cannot conceive of a rational explanation. I believe Orrell had something to say about it in EconoMyths but I can't quite recall what it was just now.In absolute contradiction to global trends though, my department is dominated by females (9 out of 50 in my class are male!) How many of us will veer towards academics,though? The probability that any given student from my class who pursues econ, is female, is ofcourse higher...but statistical forecasts are known to have been terribly wrong in the past.Ah well...Time will tell.
