This simply isn't true when it comes to the topic of economics, and there are heterodox-y economists (Tyler Cowen for example) who also respect Krugman as an economist even if they don't agree with him on everything. As for paying much attention to him in academia, afaik he's not really active in the publish or perish academic game anymore so I don't get this as a criticism, but his influences are still there.
