Politics of Companies

Musing again on 'What is a Company ?' (like I said, there's no cure), it occurs to me to wonder whether any theorist has approached them as Aristotle does the various social groupings in the Politics - starting up from the sole trader (or wherever) - 'a god or a beast' ? Hmm ... - and then debating which form of corporate governance (a mixed one ?) is best. The idea is so obvious that someone must have done it: I'll let you know what I find.
