Subdirectories DO NOT reduce PR by anything,
You could have domain.com/foo/foo/foo/foo/foo/foo/foo/foo/
and if it has identical links to domain/foo/ – it will have the same PR.
URL structure has nothing to do with it – (internal) linking determines the PR.
Yep. Subdirectories do have an effect on the SERPS – but nothing to do with PR.
