Sources on competition policy Are there any good books or blogs on Economics in Competition Policy?

I am primarily interested in US and EU.

I know of the Motta and Bishop-Walker books but I would like something with more details on the economic methods.

E.g.: 


more details on the econometric methods 
more details on acquiring or cleaning data
more details on the industrial organization (or other) models used
I was recently recommended 'Quantitative Techniques for Competition and Antitrust Analysis' by Peter Davis and Eliana Garcés. While it does not contain all the necessary info, it does refer to more specified books.
