Replication data for: A Study of the Internal Organization of a Bidding Cartel

This paper examines bidding in over 1,700 knockout auctions used by a bidding cartel (or ring) of stamp dealers in the 1990s. The knockout was conducted using a variant of the model studied by Daniel Graham, Robert Marshall, and Jean-Francois Richard (1990). Following a reduced form examination of these data, damages, induced inefficiency, and the ring's benefit from colluding are estimated using a structural model in the spirit of Emmanuel Guerre, Isabelle Perrigne, and Quang Vuong (2000). A notable finding is that nonring bidders suffered damages that were of the same order of magnitude as those of the sellers. (JEL D43, D44, L12)
