I’d like to repeat how surprised I am at the size of the gains from drilling, or at least what appears to be the best current estimate of such gains. What happened is simple. I read people writing "Price won’t go down much from drilling, therefore the gains are small," in various ways. That is a non sequitur because there is producer surplus as well! I committed a simple error. Yet again. And I committed this error because it fit in with my (nonetheless largely correct) preconception of politicians as bozos who will say anything for political gain or to sound good on TV.
