To an economist, every monopoly looks the same, whether it deviously eliminates rivals, secures a license from the state or innovates its way to the top. I'm not interested in illegal bullies or government favorites: By "monopoly," I mean the kind of company that is so good at what it does that no other firm can offer a close substitute.
which is simillar to Robin Hanson's "manic" monopolist
One simple robust solution to the innovation problem would seem to be manic monopolists: one aggressively-profit-maximizing firm per industry. Such a firm would internalize the entire innovation problem within that industry, all the way from designers to suppliers to producers to customers – it would have full incentives to encourage all of those parties to put nearly the right amount and type of efforts into innovation.
It's not about rent seeking, or some silly brand recognition narcissism, but about being able to coordinate and do stuff that would be widely beneficial but unprofitable for any of the participants on their own.
