How to curb the bias against female experts

Does the public take more notice of the opinions of male or female economists? We know that female experts, whether in science, politics or the media, suffer from an authority gap: their expertise is often not given as much weight by the public as opinions held by less qualified men. But does the gap persist for the very highest achievers? And, if it closes or even reverses for them, what lessons are there for other female experts?  Sarah Smith of the University of Bristol and CEPR recently conducted an experiment about which expert economists are most likely to influence public opinion. She tells Tim Phillips about a signal that reverses the authority gap, and how this insight can help other female economists to communicate their expertise.
