An empirical investigation of efficiency and price uniformity in competing auctions

This paper investigates hypotheses related to efficiency and price uniformity in online competing auctions based on two theoretical predictions from Peters and Severinov [Peters, M., Severinov, S., 2006. Internet auctions with many traders. Journal of Economic Theory 130, 220–245]. The investigation is conducted using a large and ideal data set for online competing train ticket auctions, and the findings support the theoretical predictions in large parts.
