Fight! Fight! Jonathan Portes describes Krugman versus the European Commission.
Dani Rodrik, always worth reading, attacks political economy. I am pretty sympathetic, but will register a quibble. The -- commonly made -- argument that "endogenizing politicians' behaviour leaves analysts with no policy recommendations to make" has some force, but can be overplayed. The material and electoral interests that politicians face are real, and even quite idealistic politicians will be helped by being made aware of them.
