Dutch type auctions, used to sell fruits and vegetables, are special resources allocation procedures. In this article, we study the mechanism properties through the bidding theory methods. The Dutch auction is often preferred to other allocation procedures for several reasons: it's an efficient and very fast revelation mechanism, which is fair.
