I understand it as buying on Mt Gox is a premium over the other exchanges because of safety. BTC-e is based in Bulgaria, won't release their company information, and could close doors at any time and disappear with everyones BTC- so it trades at a lower price there because of the extra risk.

Mt Gox is based in Japan, and very public about operations.

I'm going a bit off topic here, but one of the major weaknesses I see of Bitcoin are the exchanges. For the currency to survive, in the way it was intended, I think there needs to exist a decentralized exchange as secure as Bitcoin itself. If someone wants to work on this, shoot me an email.
