Right, I should have thought of that. Still I would be interested to see 
a direct comparison between the AB approach there and a competing C 
model doing the same thing. (It's a bit off-topic here, but if you have 
literature pointers they would be welcome.)


I think Caldara - Kamps (ECB WP, 857 I think) is what you would like to see for the US.
