How category characteristics affect the number of store brands offered by the retailer: a model and empirical analysis

Our research examines why retailers offer, not one, but multiple store brands in some product categories. More specifically, we are interested in how certain product category characteristics affect the number of store brands. We model a product category consisting of two incumbent national brands that may differ in strength. The retailer may introduce one or two store brands depending on which maximizes category profits. Our analysis suggests that the retailer is likely to carry two store brands in categories where (i) the national brands are similar in strength; and (ii) the price sensitivity between the national brands is low. Interestingly, the conditions that support the introduction of more than one store brand are quite different than the conditions that would facilitate the introduction of additional national brands. We provide empirical evidence that support our model-based predictions.

Playing safe in coordination games:: the roles of risk dominance, payoff dominance, and history of play

This paper presents results from a series of experiments designed to test the impact on subject behavior of changes in the risk dominance and payoff dominance characteristics of two player coordination games. The main finding is that changes in risk dominance significantly affect play of the subjects, whereas changes in the level of payoff dominance do not. Observed history of play also has an important influence on subject behavior, both when subjects are randomly rematched after each game and when they remain matched with the same individual for a sequence of games.

基于微分博弈的乳制品供应链质量管理研究

考虑到合理的成本分担及公平的利润分配是影响乳制品供应链系统稳定及乳制品质量保证的重要环节,本文以一个乳制品加工企业、一个奶农(牧场)和一个零售商所构成的三级供应链为研究对象,引入微分博弈的方法,研究在4种不同的乳制品质量管理博弈情形下,乳制品供应链上各成员企业愿意为质量管理工作付出的努力及其收益.研究结果表明,乳制品加工企业的质量控制和质量改进两种工作的努力程度在3种非合作质量管理博弈情形下具有相同的表现,而在合作质量管理博弈情形下,为了供应链整体利益考虑,核心企业即乳制品加工企业的质量管理工作努力程度发生了变化.而对于乳制品供应链上游的奶农和下游的零售商而言,二者对于质量管理工作的努力程度随着乳制品供应链合作的深化而不断提高,在理想的合作博弈情形下达到了最高.     

A Negotiation Model for Inducing Higher Service in a Distribution Channel

This paper analyzes, in the context of negotiation, the problem of coordination and conflict resolution between the manufacturer (Seller) and the retailers (Buyers) for a two-tier inventory system. The retailers capture demand (from customers) and therefore are responsible for the level of service offered by the system. The larger the inventory that a retailer has of a particular product, the lower the probability of running out of stock and therefore, avoid the possibility of a lost sale for the manufacturer. A conflict arises (and therefore the negotiation process starts) when the manufacturer wants the retailer to increase the level of service while retailers are satisfied with the status quo. Using the Nash bargaining solution, we develop a theoretical framework that incorporates behavioral dimensions and predicts the outcome of “sharing” the profit. The results indicate the advantage of developing long term relationships among the members of the distribution channel to minimize the uncertainty and therefore the source of conflict.

中国农村环境关系失衡的博弈分析

环境关系是环境主体间的利益关系,环境侵权的发生是环境关系失衡的主要表现,中国农村环境污染态势加剧主要根源于中国农村环境关系失衡.环境污染的过程就是环境主体间的博弈过程,中国农村环境主体间的博弈具有很多特点,分析中国农村环境侵权发生的微观机理,可以比较准确地把握中国农村环境关系失衡的本质.要改善中国农村环境污染状况,就必须改善中国农村居民在博弈过程中的微弱地位,形成良性的环境关系制衡机制,从而使中国农村环境关系从失衡走向和谐.     

博弈论和委托代理理论视角下的反洗钱监管研究

本文从反洗钱监管机构和金融机构的博弈分析入手,研究监管的最优化问题。分析得出监管机构必须对金融机构进行反洗钱约束,否则金融机构就会违规获益;最优事后监管并不能杜绝违规行为,而只是将违规行为控制在一定的范围;有效反洗钱监管需要额外成本等结论。在此基础上,本文提出实现我国反洗钱最优监管的政策建议。
