Call Auction ExperimentsIn a call auction participants indicate their willingness to buy or sell units of a good by placing an order to buy or sell some number of units at their buying or selling price. At some point in time the orders collected so far are matched together to form contracts. Different auctions follow different rules about the acceptance of orders, feedback about orders in the system, rules for updating or withdrawing orders, when to do the match, how to do the match, and the form and content of the resulting contracts. Auctions can also become more complex in the definition of a unit to include variable attributes and bundling options. |
