In the CAT Tournament, agents facilitate transactions between buyers and sellers with the intention of maximizing profit from commission and other fees. The agent must find a well-balanced strategy that allows it to sign buyers and sellers to trade in its market while also maintaining the buyers and sellers that are currently subscribed to it. One approach is to classify the traders that intera...

We are given a set $A$ of buyers, $B$ houses, and for each buyer preference list, i.e., an ordering the houses. A house allocation is injective mapping $\tau$ from to $B$, strictly better than another $\tau'\neq \tau$ if every $i$, $\tau'(i)$ does not come before $\tau(i)$ in list $i$. Pareto optimal there no allocation. Let $s(\tau)$ be image (i.e., houses sold $\tau$). interested largest poss...

Abstract Prior studies show that coordinating supply chain inventories with common replenishment epochs (CRE) provides benefit for vendor and buyers. Coordination using selective discount (SD) strategy allows some buyers to participate in the coordination scheme while other buyers continue to order as earlier. This can reduce the vendor’s total cost more than that of all buyers participating an...

In this paper, we examine the application of electronic marketplaces, populated by buying and selling agents representing their human users, learning about potential business partners and making recommendations to their users. We propose a novel incentive mechanism to address the unfair rating problem arising when modeling the trustworthiness of selling agents relies on propagation of ratings p...

In commercial transactions, trust in sellers (TIS) is the degree of trust that buyers bestow upon sellers. The existence and level of TIS is obviously a factor determining whether buyers will buy. TIS is particularly important in consumer-to-consumer e-commerce transactions, such as online auctions, which are characterized by anonymity and asymmetric product quality information. Given the impor...

Under the optimal scheme identified in Theorem 2, the response by each buyer moves in the direction of the response dominant among their predecessors. In other words, a buyer accepts with a higher probability than his predecessor when most buyers before him have chosen to accept, and rejects with a higher probability when most buyers before him have chosen to reject. Formally, the following pro...
