We provide evidence of anchoring effects from the sealed-bid auctions of vehicle plates in Macao. Vehicle plates are homogeneous in use value and differ only in character and numerical sequences. Nevertheless, vehicle plates with particular numerical sequences are consistently and repeatedly auctioned off in Macao, thus providing unique panel data that facilitate the identification of an anchoring effect. We adopt a hedonic pricing model to estimate the rational price of vehicle plates. We find that when bidding on a numerical sequence, bidders anchor on the winning bid in the previous auction, which result in continuation of the winning bid price.
