Partial resale refers to the business scenario where some resale activities, yet not all, are feasible. A paper by Geng, Wu and Whinston[12] finds that a time-restricted resale market may benefit a ticket seller more than both unrestricted resale and no resale. This paper extends the study on profitable partial resale model in two directions with both theoretical and practical importance. First...

Shill bidding occurs when fake bids are introduced into an auction on the seller’s behalf in to artificially inflate final price. The seller either has associates bid auctions, or controls multiple bidder accounts that used for shill bidding. We proposed a reputation system referred as Score indicates how likely is be engaging price inflating behaviour specific auctions. A potential can observe...

In the variable supply auction considered here, the seller decides how many costumers with unit demand to serve after observing their bids. Bidders are uncertain about the seller’s cost. We experimentally investigate whether a uniform or a discriminatory price auction is better for the seller in this setting. Exactly as predicted by theory, it turns out that the uniform price auction produces s...

When the seller of an asset grants a right-of-first-refusal to a buyer, this special buyer has the opportunity to purchase the asset at the best price the seller can obtain from the other potential buyers. We show that the right-of-first-refusal is inefficient, and it benefits the special buyer at the expense of the seller and other buyers. In a private values model, the benefit from granting a...

In this paper, several seller–buyer supply chain models are proposed which incorporate both cost factors as well as elements of competition and cooperation between seller and buyer. We assume that unit marketing expenditure and unit price charged by the buyer influence the demand of the product being sold. The relationships between seller and buyer will be modeled by non-cooperative and coopera...

A seller can achieve the desired prevention of information acquisition through posted-price selling, by offering prospective buyers a discount that is such as to deter them from gathering information. No such preventio...

We model competition between two firms selling identical goods to customers who arrive in the market stochastically. Shoppers choose where to purchase based upon both price and the time cost associated with waiting for service. One seller provides two separate queues, each with its own server, while the other seller has a single queue and server. We explore the market impact of the multi-server...
