And I think–I listed, in the essay, four key research areas. And one of them is what I call Firm Interaction. And this question of how the ecosystem operates now, in these various industries, is a really important question. As is what the traditional boundaries of the firm question: what should be done inside the firm and outside the firm? I mean, I’m shocked at the breadth of Amazon. I mean, it’s incredible, the breadth of that firm. I don’t think any theory of the firm that economists–economists haven’t done much with their theories of the firm, because again it becomes an intangible issue of, you know, what should you do inside the firm and outside the firm. It all depends on intangible things, and economists don’t do well with intangible things. But, I don’t think anybody, from Coase, or Williamson, or anyone who has looked at that would have told you that something with the breadth of Amazon would have emerged.
