Is the following sentence acceptable in formal, academic writing?
... relatively higher UI benefits in a particular province encourage in-migration to and inhibit out-migration from that province.
While the sentence seems idiomatic to me, I am not sure if such a case of ellipsis is considered acceptable in a formal setting.
This sentence is different from other simple examples of ellipsis. For example, the omission of regions in "... reduced geographic mobility from low productivity to high productivity regions" is completely fine in formal writing.
In my original sentence, I omitted the first "that province", which left a hanging "to" there. I think the problem arises because the elements in the two predicates are different - encourage in-migration and inhibit out-migration.
I have seen constructions that use a parenthesis in such cases:
... relatively higher UI benefits in a particular province encourage in-migration to (and inhibit out-migration from) that province.
I don't know if that solves the problem or not. It does make it look better than " ... to and inhibit ...".
I am not asking for help in rephrasing the sentence. I can do that. I am interested in knowing if it is grammatical (if not, why?), and if it is acceptable in academic writing.
