We hear a lot about the under-representation of women in so-called STEM fields - science, technology, engineering and maths.
But the proportion of women in economics is by some measures smaller.
Only one woman has ever won the Nobel Prize in economics - American Elinor Ostrom in 2009.
And there wasn't even a single woman on some of the lists floating about guessing who this year's prize winner would be - it went to the behavioural economist Richard Thaler.
Some have argued that these figures aren't necessarily the result of bias.
