The first part of the paper reports the results from a sequence of laboratory experiments comparing the bidding behavior for multiple contracts in three different sealed bid auction mechanisms; first-price simultaneous, first-price sequential and first-price combinatorial bidding. The design of...

Within the framework of the common value model, we examine the magnitude of the difference in expected outcome between first-price and second-price sealed bid auctions. The study is limited to two empirical specifications of bidders signals: Weibull and normal distribution. The optimal bid...
