I think economics got there first; that looks like http://en.wikipedia.org/wiki/The_Nature_of_the_Firm http://en.wikipedia.org/wiki/The_Nature_of_the_Firm : companies form, even in an efficient market, because they can potentially globally optimize groups of individuals into more efficient interactions than the individuals themselves could in any market. The other side of it is that such optimization doesn't scale and a sufficiently large firm will be unable to find practical solution at all.
