Female tennis players play more conservatively and commit more
unforced errors when playing critical points. Does this explain the
upper-echelons wage gap?
Here is the fact in more detail:
Women are significantly more likely to hit unforced errors at the most
crucial stages of the match, while men exhibit no significant variation
in performance. Specifically, about 30% of men’s points end in unforced
errors, regardless of their placement in the distribution of the
importance variable. For women, about 36% of points in the bottom
quartile of the importance distribution end in unforced errors, but
unforced errors rise to nearly 40% for points in the top quartile of
the importance distribution. What is remarkable is not the difference
in the levels (men are more powerful and therefore more likely to hit
winners at any stage). The interest lies in the differences in the way
men and women respond to increases in competitive pressure.
