Becoming a Resident in a High Demanded Medical Specialty: an Unequal Race? Evidence from the Spanish Resident Market

Background: Gender occupational segregation in medicine is associated with several undesired consequences such as earnings disparity, shortages of specialists or lower quality of care among others. This paper focuses on the persistent gender gap observed in the most popular specialties of the Spanish resident market. In particular, it explores the role of the specialty allocation system in perpetuating the occupational segregation. For that purpose, this paper studies the effect of a policy change in the ranking system that determines doctors' specialty choice order. The change increased the competitiveness of the process by increasing the weight of an entry examination from 75% to 90%, in detriment of doctors' grade point average that decreased from 25% to 10%. Findings from previous literature suggest that that male and female doctors might have reacted differently to the increased competitiveness of the process.

Methods: Data come from administrative records of doctors' specialty choices for the years 2013 and 2015 and they are used to compute the difference between doctors' pre and post-change ranking positions. Then, differences in the distribution of rank differences between male and female doctors are tested by means of parametric (T-test) and non-parametric (Wilcoxon rank) approaches.

Results: Results show that the policy change has overall favoured male doctors. On average, female doctors lose ranking positions, with respect to the position they would have achieved with the old weights, whilst male doctors gain positions. The differences are more pronounced in the top half of the ranking distribution, meaning that female doctors on average have reduced their probability of accessing the most demanded specialties.

Conclusions: The objective of the policy was the enhancement of the prospects of Spanish-graduate doctors with respect to international graduates by giving more weight to the less prone to bias examination scores. Nonetheless, the change have had the unintended consequence of reducing the probability of female doctors accessing highly demanded specialties and thus exacerbating the gender gap. The allocation system needs revision to make it accountable for the actual role of doctors in society.
