"Identifying Collusion in English Auctions with Unobserved Heterogeneity"

Webpage

ABSTRACT: We consider English auctions with asymmetric bidders and additive unobserved heterogeneity or common value components. We show that the bidders’ individual distributions as well as the distribution of the unobserved heterogeneity or common value component are nonparametrically identified. Moreover, these objects are also nonparametrically identified when an unknown subset of bidders form an efficient cartel. The identification results can be used for detection of colluding bidders.

This is an online seminar which will take place via Zoom. The link to the seminar will be distrubted by invitation only. Please contact lyudmila.vafaeva@hhs.se if you would like to attend the seminar.
