Did the Rise of China Help or Harm the US? Let's not forget Basic Macro

Douglas Campbell:

Did the Rise of China Help or Harm the US? Let's not forget Basic Macro: This is a question which was posed to me after I presented last week at the Federal Reserve Board in DC. Presenting there was an honor for me, and I got a lot of sharp feedback. It's also getting to the point where I need to start thinking about my upcoming AEA presentation alongside David Autor and Peter Schott, two titans in this field who both deserve a lot of credit for helping to bring careful identification to empirical international trade, and for challenging dogma. After all, before 2011, as far as I know the cause of the "Surprisingly Swift" decline in US manufacturing employment had not been written about in any academic papers. This was despite the fact that the collapse was mostly complete by 2004, and was intuitive to many since it coincided with a large structural trade deficit. (Try to explain that one with your productivity boom and slow demand growth, Robert Lawrence...) 
On one hand, there is now mounting evidence that the rise of Chinese manufacturing harmed US sectors which compete with China. This probably also hurt some individual communities and people pretty badly, and might also have triggered an out-migration in those communities. On the other hand, typically the Fed offsets a shock to one set of industries with lower interest rates helping others, while consumers everywhere have benefited from cheaper Chinese goods. Which of these is larger? I can't say I'm sure, but of these shocks mentioned so far, I would probably give a slight edge to the benefit of lower prices and varieties. However, I suspect, even more importantly, Chinese firms have also been innovating, more than they would have absent trade, which means the dynamic gains in the long-run have the potential to be larger than any of these static gains/losses you might try to estimate courageously with a model.
Many (free!) trade economists use the above logic (perhaps minus the dynamic part), and conclude that no policies are needed to help US manufacturing right now.  However, I think this view misses 4 other inter-related points, and in addition does not sound to me like a winning policy strategy for the Democrats in 2020. And a losing strategy here means more Trumpian protectionism.
