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

Unless otherwise specified, current restrictions mean in-person seminars are only open to members of the LSE community (those with a valid LSE ID card).

Those unable to join the seminars in-person are welcome to participate via zoom.

About this event

We study an on-line market for programming services where providers are chosen through multi-attribute auctions, a mechanism that takes into account seller's non-price characteristics as well as his bid. We develop empirical methodology for recovering the joint distribution of buyers' outside options and weights for sellers' attributes as well as other primitives of the model while allowing that an important component of seller's quality known to buyer may be unobserved to the researcher. The methodology is designed to accommodate two important features of such markets: buyer-specific choice sets and high turn-over of sellers. Our empirical results confirm that (unobserved) quality plays an important role in this environment. We also find that internet enables buyers to substantially improve on their outside (local) option with the larger part of gains arising due to the access to low-cost per unit of quality providers.

Industrial Organisation seminars are held on Mondays in term time at 12:30-14:00, ONLINE, unless specified otherwise.

Seminar organiser: Alessandro Gavazza.
