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.
