103/ seems to me from reading this and some of the references that the disagreement seems to be “technical”. Krugman seems to agree that the fear of deficits is overblown, but seems to argue that interest rates are another tool to manage possible inflation. Tbh I haven’t gotten the opposite impression yet from the book, but maybe I missed it.
One thing I do wonder about is that if the deficit is in the form of bonds, won’t higher interest rates affect the cost of the accumulated deficit? Wouldn’t the public side now also have to pay more for the accumulated deficit? How does that work?
Maybe I don’t know how any of this works
