* Just 4 per cent of economics professors are women, a study from the Royal Economic Society's Committee on Women in Economics has found. The study, by Alison Booth of the University of Essex, found that in economics, women make up 32 per cent of PhD students, 28 per cent of fixed-term lecturers, 17 per cent of permanent lecturers and 11 per cent of readers and senior lecturers. She said that there was no evidence to suggest that women lacked interest in the subject, but that they lacked role models and mentors in economics.
