Optimal design of auction is one of hot research topics in the auction theory. During recent years, shill bidding has increased substantially with the explosion in the number of online auctions. This paper designs the optimal online auction with shill bidding and open reserve price. Many optimal auction models have assumed that the number of potential(More)
Polystyrene-ethylene-butylene sulfonate copolymer membranes (PSEBS) were photochemically cross-linked using benzophenone as the photo-initiator. Benzophenone decomposed by first-order kinetics during the cross-linking process. The cross-linked PSEBS had lower water swelling, lower proton conductivity, and higher chemical stability than un-cross-linked(More)
This paper presents the theory of dynamic sequential auctions which can be used for pricing and inventory control in online auction. Most theoretical treatments of auctions have assumed that buyers have unit demand, which didn't conform to the real state. We characterize this model when a seller with C units to sell by the way of sequential auctions faces a(More)
Optimal design of auction is one of hot research topics in the auction theory. In this paper, we design this online auction mechanism, by considering simultaneously the bidders' stochastic arrival process, entry fee, which is proportional to the reserve price seller, commission rates, which is proportional to the ultimate winning price from the seller if(More)
