Ben Brooks (University of Chicago), joint with Dirk Bergemann and Stephen Morris

Thursday 19 November 2015 15:30 - 17:00

Many of our seminars and public events this year will continue as in person or as hybrid (online and in person) events. Please check our website listings and Twitter feed @STICERD_LSE for updates.

Unless otherwise specified, in-person seminars are open to the public.

Those unable to join the seminars in-person are welcome to participate via zoom if the event is hybrid.


About this event

This paper explores the impact of private information in sealed bid first price auctions. For a given symmetric and arbitrarily correlated prior distribution over values, we characterize the lowest winning bid distribution that can arise across all information structures and equilibria. The information and equilibrium attaining this minimum leave bidders uncertain whether they will win or lose and indifferent between their equilibrium bids and all higher bids. Our results provide lower bounds for bids and revenue with asymmetric distributions over values. We report further analytic and computational characterizations of revenue and bidder surplus. Our work has implications for the identification of value distributions from winning bid data and for the informationally robust comparison of alternative mechanisms.

Economic Theory Seminars are held on Thursdays in term time at 15:30-17:00, ONLINE or ONLINE AND IN PERSON at the same time.

Seminar organisers: Dr Andrew Ellis and Dr Christopher Sandmann.
