Collusion, for fun and profit: Marshall and Marx

I was delighted to receive in the mail the new book The Economics of Collusion: Cartels and Bidding Rings, by Robert C. Marshall and Leslie M. Marx.

The book is devoted to the description and analysis of explicit collusion (their emphasis). I haven't read it yet, but one of the things that makes explicit collusion so entertaining to study and read about is that there are often detailed accounts (typically from court cases) about just how the collusion was accomplished.

Examples:
Marshall:  "Collusive Bidder Behavior at Single Object Second price and English Auctions," with D. Graham, Journal of Political Economy, 1987, 95, 1217-1239.

John Asker: A Study of the Internal Organisation of a Bidding Cartel

American Economic Review, v100(3), 724-762, 2010.
