The gender gap in expert voices: Evidence from economics

In economics, as in other domains, male experts are overrepresented in public debates. The underlying reason for this is unclear. A demand-side explanation is that female experts are less frequently asked to give their opinion; a supply-side explanation is that, conditional on being asked, female experts are less willing to give their opinion. Analysing an existing panel of expert economists, all asked for their opinions on a broad range of issues, we find evidence of a supply-side gap: male panel members are more likely to give an opinion, and this is the case in all fields of economics and on both in-field and out-of-field topics.
