I'm curious how these studies consider factors like race and ethnic background. In the US for example, Latinos earn less than whites for a lot of reasons. Latino men are also shorter overall than white men. But we can think of a lot of relevant reasons Latino men might earn less than white men in the US before we'd start thinking about specific physical characteristics.
