Implicitly

[Pvunderink]

Can someone please explain to me if their should be a comma after the word 'Implicitly'?

Sentence:
"Implicitly, this assumes that the quality of schooling does not vary among countries."

'This' refers to the previous sentence: 'The analysis of the impact of educational differences among countries is based on the gross enrollment ratio.'

Yes, it would be usual to put a comma there, but it would be better to change the word order to "This implicitly assumes", in which case there should be no comma.

Thank you Edinburgher!
