How Group Leaders Build Stable Community Buying Groups:A Perspective Based on the Differential Mode of Association

Since 2016,community group buying has grown significantly in China,largely driven by its efficient logistics,supply chains,low prices,and convenience.This model has been further popularized during the COVID-19 pandemic due to its effectiveness in meeting daily needs while minimizing human-to-human contact.A key component of this business model is the“group leaders”-influential individuals within a community responsible for managing group buying activities,which include order collection,supplier liaison,and goods distribution.Their primary task is to form and sustain a reliable community group buying consortium,a task that demands excellent organizational and interpersonal skills.This paper examines this phenomenon using the lens of the differential mode of association,a theoretical model explaining interpersonal relationships in traditional Chinese society.The research indicates that group leaders,through regular interaction with consumers,are able to alter their social network position,increase their influence,understand consumer needs,provide satisfying services,and enhance trust,thereby transforming consumers into loyal group buying participants.This transformation not only brings stability to group buying activities but also reinforces the community influence of group leaders,thus fostering the growth of community group buying.

Group Buying of Competing Retailers with Fairness Concerns

The fairness concern behavior is particularly common among members in supply chain framework.The downstream retailers often compare their profits with those of the other members in the supply chain,especially that of the supplier,and do not like the unfavorable distribution of the total profits.This work considers a supply chain consisting of a supplier and two competing retailers with fairness concerns.The supplier offers a wholesale contract with quantity discount,and the two competing retailers have the options of individual purchasing and group buying.Through a Stackelberg game model,the optimal decisions for the players are obtained for the group buying and the individual purchasing strategies.The results indicate that the supplier benefits more than the retailers from the group buying strategy.In particular,the group buying strategy gives the supplier a higher profit if the operational cost of group buying is below a threshold.Furthermore,the fairness concern behavior of the retailers does not always hurt the profit of the supplier.Specifically,the supplier will benefit from the fairness concern behavior of the retailers in individual purchasing when the retailers operates in a relatively poor environment.Finally,market competition between the two fairness concerned retailers does not always benefit the supplier.Fierce competition between the fairness concerned retailers reduces the supplier's profit if the group buying strategy is used when the retailers operates in a relatively poor environment.

CONSUMER-DRIVEN GROUP BUYING： TRICK OR TREAT TO RETAIL STORES？

Group buying （GB） has emerged and evolved into various forms over the past decade. We investigate a distinct form of GB, namely consumer-driven group buying, whereby some consumers form purchase groups to visit stores together and negotiate for discounts. We refer to these consumers as GB consumers that differ from regular consumers who visit stores individually and pay regular prices. Visited by a purchase group, a store has to make an immediate decision to serve their demand in its entirety. Turned down by the first store it visits, the purchase group continues to visit the other store. After accommodating GB demand, the stores use remaining stocks to serve regular consumers. We demonstrate that GB can be a treat to stores that adopt proper policies to utilize it as an instrument to reach consumers. The stores are able to accommodate group demand at a price lower than regular price in most circumstances but still manage to earn stable profits. The presence of regular consumers has a subtle effect on equilibrium formation, by strengthening the stores＇ power in negotiating with GB consumers to make group price weakly increase with group size. Moreover, competing stores are able to manipulate the interactions between purchase groups and collectively earn a higher total profit than a monopolist store when GB consumers account for a small fraction of market base and competition is intense.

Cost Sharing Based Truthful Spectrum Auction with Collusion-Proof

Spectrum auction is an important approach of spectrum distribution in cognitive radio networks. However, a single secondary user(SU) probably can't afford the price of spectrum. Multiple SUs grouping together to participate in the auction as a whole is helpful to increase purchasing power. However, SUs could suffer from a new group cheating problem, i.e., parts of users conspire to manipulate the auction by submitting untruthful bids. Existing auction mechanisms were mainly designed to be strategy-proof only for individual user and can't deal with group cheating. In this paper, a novel spectrum auction mechanism called COSTAG(COst Sharing based Truthful Auction with Group-buying) is proposed to address the group cheating problem. COSTAG consists of a grouping rule to perform grouping and a payment rule to determine the market-clearing price in the spectrum auction. Different from single-echelon pricing approach employed in existing works, a multi-echelon pricing strategy is designed to increase the transaction rate and optimize social profit for the auction. Comprehensive theoretical analysis shows that COSTAG can satisfy the crucial economic robustness properties, both individual and group truthfulness. Simulations demonstrate that comparing with existing works, COSTAG can improve the system performance significantly.
