In this study we quantify the size and drivers of the contemporary gender pay gap among medical doctors employed in the UK public sector. In using nationally representative data from the Annual Survey of Hours and Earnings, we make comparisons to doctors employed in the private sector, as well as to other public sector medical professionals. We find that the substantial 20 per cent hourly gender pay gap among public sector doctors is far larger than in either of these comparator occupations. Decomposing the mean gender pay gap for public sector doctors, we find that it is largely unexplained by personal and work-related characteristics, consistent with evidence of potential substantial gender inequality in rewards. It is at the top end of the wage distribution where this is most pronounced indicating the presence of a ‘glass ceiling’ in UK medicine.
