> Studies about the wage gap look for reasons why companies compensate women less

You're really begging the question here. You're assuming that companies do pay the women less regardless of their contributions to the company. As I have said before, there are dozens of studies out there, and you can find evidence for and against the existence of a non-justified gender wage gap.

> Research on the wage gap doesn't conclude that these causal factors morally justify the wage gap, because they don't.

That doesn't make sense. If adjusting factors for contributions to the company reduce the wage gap to zero, there is no wage gap and there is no moral justification needed.

Identifying reasons for the wage gap doesn't make the wage gap go away. The gap is still there because women still earn less. So unless you believe women are worth less than men the wage gap is a problem.
