3. Paul Krugman responds on corporate tax incidence. I see this as a classic case of “as usual the truth lies somewhere in between.” In response to Paul, foreign capital goes after American rents all the time (ask Toyota), exchange rate overshooting models have little validity in the data (“news” moves exchange rates), and I don’t see why the long-run is a bad guide to tax policy. That said, I do think more of the burden of capital taxation falls on capital than labor, but plenty falls on labor nonetheless. See the most recent comments from Summers, stronger arguments overall.
