French firms tend to specialize in certain types of inequalities. Firms in the finance sector have a larger gender gap but a smaller migrant gap. In contrast, firms in the retail, accommodation, and social services sectors have smaller gender gaps but larger migrant gaps.
[n/n]

Using DADS admin data from France (1996-2021), we find that firms with higher gender gaps have lower migrant gaps, and vice versa. Firms with high gender gaps are also highly unequal within gender/migrant categories. In contrast, firms with high migrant gaps are firms are less unequal.

And the question is not easy to answer, either. Gender and migrant wage gaps are estimated using the same underlying variable: wages in the same establishments. There’s a big risk of capturing artifacts. Therefore, in the appendices, lots of equations we had a hard time solving…

– So?
– Well, we’re just asking a very simple question.
Are firms that are highly unequal in terms of gender also highly unequal in terms of migration origin?
It’s trivial once you know the answer… But before that, the answer is not easy to guess… Try!

– Hmm … INTERSECTIONALITY? This must be dangerously WOKE…
– Nope
– Oh ... “organizational intersectionality”? This must talk of the complexity of the lived experiences of those facing in organizations multiple prejudices at the intersection of many minorized dimensions.
– Not really either.

As @oliviergodechot.bsky.social notes, in some ways this could be seen as an example of "big" science:
coauthors: 29
years it took: 9
countries: 12
pages (w/ appendices): 111
observations: 1,164,687,821

But it can be summarized in one 5-word sentence: Top earners increasingly work together. PERIOD.
