We analyze bidding behavior in auctions when risk-averse buyers bid for a good whose value is risky. We show that when the risk in the valuations increases, DARA bidders will reduce their bids by more than the appropriate increase in the risk premium. Ceteris paribus, buyers will be better off bidding for a more risky object in first price, second price, and English auctions with affiliated com...

Interactive pricing mechanisms integrate customers into the price-setting process by letting them submit bids. Name-your-own-price auctions are such an interactive pricing mechanism, where buyers’ bids denote the final price of a product or service in case they surpass a secret threshold price set by the seller. If buyers are given the flexibility to bid repeatedly, they might try to incrementa...

Collusion between suppliers in reverse auctions may damage buyers’ benifits and then lower efficiency of resource allocation. Under first-price sealed-bid reverse auction mechanism, suppliers' equilibrium bidding strategy and buyers' revenue loss was analyzed considering collusion. Then some general conclusions were given: suppliers' bidding strategy is relevant to some factors such as valuatio...

In the CAT Tournament, specialists facilitate transactions between buyers and sellers with the intention of maximizing profit from commission and other fees. Each specialist must find a well-balanced strategy that allows it to entice buyers and sellers to trade in its market while also retaining the buyers and sellers that are currently subscribed to it. Classification techniques can be used to...

A single object is for sale to N asymmetric buyers in the independent private values setting by means of an English auction. We consider implications of seller’s active participation in the bidding process, or shill bidding. The main result is that there exists an equilibrium of the English auction with shill bidding that is outcome equivalent to the optimal mechanism of Myerson (1981). Thus, a...

We consider a population of buyers who have unit demand for a homogeneous good, and only differ in terms of how soon they need to purchase it. These buyers have access to a stochastic stream of second-price auctions, as well as a retail outlet that can be used at any time. We characterize the equilibrium bidding dynamics, showing that bidders steadily raise their reservation price as they appro...

In this paper, we develop a detailed bidding strategy for selling agents in electronic marketplaces, in a setting where buyers and sellers have incentives to be honest, due to a particular framework for trust modeling. In our mechanism, buyers model other buyers and select the most trustworthy ones as their neighbours to form a social network which can be used to ask advice about sellers. In ad...
