Trade Diversion defending Krugman

For those who are not regular readers of Trade Diversion, Jonathan Dingel has been providing several points of defense for Krugman against a barrage of political attacks generated solely due to the recent annoucement of his impending Nobel.  The barricade so far includes these posts:

Original Defense

Additional fortification

Redoubt and attack

The introduction to the last post is amusing in itself.  While providing insights into his work for the unfamiliar reader, it will force me to add some Krugman to my own reading list.
