The Sealed-Bid Mechanism: An Experimental Study*

This paper presents the results of a set of experiments performed to test the properties of a bargaining mechanism (called the sealed-bid mechanism) used to structure bargaining under incomplete information. Our results indicate that the mechanism performs quite well. When using it, experimental subjects are able to capture a large portion of the potential gains from trade. In addition, the beh...

Signed and sealed

Language constructs for defining abstract types commonly come in two varieties: those that add and remove seals dynamically as values cross the abstraction boundary, and those that define the boundary statically using a type signature. Abstract types in dynamically-typed languages are generally defined using seals whereas statically-typed languages more typically use a signature; two prominent ...

Sealed-Bid Micro Auctions

In electronic auction applications, small-value merchandise is often distributed. We call this kind of auction micro auction. Compared to traditional general-purpose electronic auction, micro electronic auction has its own special requirements. Especially, micro auction must be very efficient: the cost of the auction protocol must not be over the cost of the merchandise for sale. Although the m...

Late rupture of knitted Dacron graft.

An 87-year-old man underwent aorto-bifemoral bypass using a bifurcated Bionit II knitted Dacron graft for high aortic occlusion in 1987 at another hospital. In November, 2004, he was admitted to our institution because of difficulty in walking due to swelling and tenderness in the right groin. Computed tomography (CT) scan indicated bilateral aneurysms of the grafts in the groins. The size of t...
