As far as I can tell, Simon Wren-Lewis has been convinced by Paul Krugman. He now proposes parallel reasearch projects one of which is to be focused on fitting the data. This is exactly what Krugman advocated.
Update: clearly I couldn't see very far. In fact, as he has repeatedly written, Wren-Lewis always agreed with Krugman about what is to be done. I assume he still disagrees with Krugman about the fruits of the effort to micro found macro. In any case, I missinterpreted his new parallel research program proposal. It is the same as his original paralkel research program proposal.
Also he isn't the one who caused the Bank of England model to have an ad hoc periphery around the consistent core. That was the work of Bank of England employees. Or something. Just go to his blog for more reliably correct corrections.
