DICE Discussion Paper 54
We provide a comparison of bidding behavior between multi-round and single-round auctions considering bid lettings for asphalt construction contracts that are known to have primarily private costs. Using a reduced-form differenc-in-difference approach as well as the nonparametric estimation technique that was proposed by Racine and Li (2004) we find that bidding is more aggressive in a sequential multi-round setting than in a simultaneous single-round format. We explore potential causes for the bidding difference across formats that are related to synergies and the level of bidder participation.
