I read an article a couple years back that pointed out a sudden increase in the gender pay gap among medical professionals -- specifically, fresh graduates from medical school, going in to the same specialties. Men and women had basically been at parity within each specialty in the early 2000s, and then over the course of the last decade or so, a massive gap appeared. I read a followup paper shortly after, where they had investigated the details and found that a significant percentage of recently-graduated women had asked for reduced hours and fewer overnight shifts in exchange for lower pay, while many men had volunteered for those sorts of conditions in exchange for higher pay. The gap had actually appeared in response to trends in the lifestyle decisions of employees, rather than discrimination on the part of employers.
