I want to point out that Richard Epstein just posted a nice column on Comcast v. Behrend, which can be found here. In the column Epstein puts nicely one of the points I tried to make in my last post on Comcast:
The ultimate question in these cases is whether the price increase was attributable to the added concentration, and for that question the regressions have to be admitted because they apply to the class as a whole. The information on the four possible sources of the increase should not be looked at in the alternative; if examined at all, the theories should be treated at most as cumulative descriptive evidence that is weaker in kind than the quantitative evidence in the regression itself. It is therefore a plus that the regression is not tied to the overbuilding theory. If this analysis is correct, it is mistaken to insist that the harms suffered by the plaintiff class do not derive from the distinctive overbuilding theory put forward by the plaintiff. Instead, the numbers tell the key story, as each of the four theories mentioned could offer a partial explanation as to the subsidiary question of how the antitrust injury came to pass.
The whole thing is worth a read!
