Tick length: This allows the experimenter to set the speed at which the price decreases (in seconds).

Starting price: Here the experimenter price at which the auction will begin.

Price clock decrement: Here the experimenter specifies the amount by which the price will decrease with each tick in the auction.

Proxy bidding allowed: Checking this box will permit proxy bidding for each bidder.  When proxy bidding is permitted, bidders may specify a price they are willing to pay in the auction so they will continue to out-bid other bidders until they have reached their proxy limit.  In a dutch auction, the proxy will simply stop the clock as soon as the specified price is reached.

  • Details: Clicking the details button will bring up the screen below which enables the experimenter to specify exactly those bidders who are allowed to use a proxy.
