Abstract: We study the bid-ask spreads observed in an experimental auction market. Three results are presented. First, the trading mechanism, which can destroy order books, should modify the measure of the spreads. Second, bid-ask spreads are reliable to the nature of the environment and to the type of information received by the traders. An adverse-selection mechanism should explain the volatility of the spread. Third, the behaviour of prices and volumes depends on an ambiguous situation on the market.
