This is at Bloomberg, I think this is the most interesting paragraph:
But Noah, I have a question for you. You’ve written several columns about how the American economy is becoming more monopolistic. If true (and it is not exactly my view), that implies output could be much higher with current resources, even at full employment. A boost in demand could spur firms to produce more, rather than restricting output so much. So are you now a fan of these Trumpian deficits? They may not be your preferred form of deficit spending, but do you see them still as a net positive?
But of course there is much more at the link.
