comma before second 'and' [conjunction]: dimension and perf., and

[Evelin2208]

Hey there,

is the comma before and moderators that are expected... correct or do I have to delete it?

Then we formulate specific hypotheses on the relationship between brand dimensions and company performance, and moderators that are expected to influence that relationship.

Thank you

I would say that the comma is correct. The second "and" is performing a function similar to "as well as". The comma before the second "and" makes it clear that the final portion of the sentence is referring to "the relationship between brand dimensions and company performance."

Thank you very much

As I understand it there one hypothesis (or set of hypotheses) on "the relationship between brand dimensions and company performance" and another on "moderators that are expected to influence that relationship".
If this is correct it might be clearer to add "on the" before "moderators" (and of course leave the comma before the second "and").

Thanks Momerath, it is a set of hypotheses. I added "on the".
