Would have been more interesting if they had had data that showed statistically significant effects dependent on the name chosen. Hard to separate that from the cultural correlations though (a guess: the average Emily will earn more than the average Tawanda).
My wife and I named our daughter Maren. Probably won't become overused anytime soon. I was rooting for Gudrun myself (dropped out of the top 1000 girl's names back in the early 1900s) but my wife and I compromised ...

The really annoying thing is female imperialism of traditionally male names. Boys hate having people think they are girls. My boys are named Matthew and Peter, two names unlikely to be imperialized by girls. If this trend continues however, I intend to advise my sons to name their sons Dick, Johnson, and Pecker just to be safe.
