Dutch Auction Applet

Recent information

10-Aug-2002 Version 1.0.

A Dutch auction is characterized by its decreasing price mechanism. The auction starts at a relatively high price and repeatedly decreases the price until a “bid” is announced by one of the auction participants. The auction is then terminated and the bidder wins the auction. The Dutch auction got its name from the Dutch flower auction, where flowers are sold to traders.

This type of auction is also characterized by its speed. Usually the auctions are very short so that a lot of merchandise can be sold.


Our implementation of the Dutch auction adds some more functionality. The Dutch auction applet is an Internet based online Dutch auction based on an implementation that was created by: Ball,  J. (1997). Dutch Flower Auction Simulation Retrieved May 7, 2001, from
