The Value of Category Captainship in the Presence of Manufacturer Competition

This research investigates the value of category captainship (a management practice in which a retailer relies on a manufacturer for recommendations regarding strategic category management decisions) in retail supply chains. We consider a setting where the scope of category management is limited to assortment decisions and demand enhancing activities. We assume that the retailer selects a category captain among multiple competing manufacturers with privately known capabilities for driving category traffic. First, we consider a benchmark scenario where the retailer is responsible for category management. Then, we consider the category captainship scenario where the retailer selects one of the manufacturers as a captain to manage the category. We find that captainship is more likely to emerge in categories where the cost of managing variety, the retail margins, and the competition for captainship are moderate and the captain is more capable of driving traffic compared to the retailer. In such categories the collaboration between the retailer and the captain ensures sufficient surplus for both parties. Finally, we show that captainship can also benefit the non‐captain manufacturers.

本文认为在新贸易理论中 ,规模经济的概念是十分重要的 ,因此从其动态性、与专业化的关系以及其外部性三方面来认识规模经济 ,并由此引发了对现实问题的几点思考     

基于水资源外部性特征的配置制度安排研究

水资源的代际外部性、取水成本的外部性、存量的外部性、环境外部性和水利投资的外部性特征 ,导致市场制度配置水资源的作用失效。同样 ,水资源的商品属性和稀缺性导致政府配给制度的作用失灵。为保证水资源的有效供给和可持续有效利用 ,需要从市场机制和政府规制两方面有机结合、分层次来管理水资源     

会计信息外部性问题的经济学思考

会计信息拥有使用价值和价值,具有商品的一般属性。但是会计信息商品又与普通商品不同,具有准公共产品和外部经济性特征,是一种特殊的商品,这使得会计信息市场价格不反映实际价值,价格不能弥补成本,致使会计信息生产者为降低成本,减少会计信息供给数量,降低会计信息质量,即出现了会计信息市场失灵。为了纠正市场失灵,应采取会计信息政府管制和设立鼓励性经济奖励双管齐下的措施。     

企业创新活动溢出效应研究综述

企业创新活动会产生外部效应或者说溢出效应,由此导致企业创新活动中搭便车的行为.目前,学界关于外部效应对企业创新活动影响的研究比较多,但是对企业创新活动溢出效应的研究还比较少.在检索了“中国知识资源总库”和“中国期刊网”等相关数据库后,对企业创新活动及其溢出效应问题的相关文献进行了梳理,指出了当前研究存在的不足,并指出了今后应进一步加强研究的领域.     

Convergence or mediation? Experts of vulnerability and the vulnerability of experts’ discourses on nanotechnologies – a case study

Since 2004, risk in the context of nanotechnologies has been criticized as being too abstract and an all-inclusive category. Moreover, the concept of risk is not precise enough to describe the potential issues related to the development of nanotechnologies. Instead, experts on technological development emphasize risk communication. In the field of nanotechnologies, this term was redefined in February 2005 in relation to the question of societal acceptance of nanotechnologies. Risk communication is about gaining stakeholder acceptance of policy decisions, whilst the public and stakeholders are encouraged to participate actively in the communication process through public consultations or hearings. Thus, on the one hand, the category of risk has been pragmatically nuanced to better highlight the vulnerability of the communication of nanotechnologies. On the other hand, this vulnerable communication is not the result of a deficit of information. It is based on the idea of participation, where vulnerability hinges on the social groups specialized in the design, application and diffusion of nanotechnologies within society. How is such participation possible, and what does it entail? We develop this question in the framework of a comparative survey of experts in the development of nanotechnologies in Grenoble (France) and Hamburg (Germany).     

基于网络外部性的绿色制造策略研究

根据消费者的绿色偏好以及产品的网络外部性特征构建消费者效用函数,在此基础上,对供应链的制造策略进行分析。首先,利用逆向归纳法获得了Stackelberg均衡,并证明了产品的网络外部性对供应链成员收益存在正向影响。其次,利用比较分析法给出了制造商实施绿色制造策略的条件。然后,对信息不对称模型进行研究发现,当制造商对绿色产品网络外部性的估计满足一定条件时,零售商的信息共享策略对制造商和零售商都有利。最后,将模型拓展到混合制造策略下,并通过数值方法,讨论了各种参数变化带来的影响。所得结论对企业绿色制造决策具有重要的参考价值。     

网络外部性与企业产品兼容性决策分析

研究具有网络外部性特征的市场中,当拥有专有技术的主导厂商不能阻挡跟随厂商的市场进入时,主导厂商对其技术的兼容性授权动机.研究结果表明,在消费者对产品未来市场规模的预期为随机变量的假设下,如果网络外部性强度较弱,拥有技术标准的主导厂商将向跟随厂商开放技术标准,采取兼容性策略;相反地,如果网络外部性强度较强,主导厂商将独享技术,采取不兼容性策略.     

Software variety and hardware value: a case study of complementary network externalities in the microcomputer software industry

We estimate the effects of software provision on the valuation of hardware in the early microcomputer industry, covering the period 1981–1986. Since hardware and software technologies `co-evolve,' a discussion of the economic and technological relationships is provided to clarify the nature of the relationship between software variety and hardware price.     

网络外部性、差异化竞争与主流化策略研究

本文将网络外部性同顾客选择与产品差异化理论结合,通过构建扩展的豪泰林模型研究了网络外部性对市场绩效与企业竞争策略的影响。研究主要表明:当某种网络产品成为主流化产品时,将比非主流化产表现出更强的网络外部性,并且价格和厂商利润均高于非主流化产品。最后,本文对网络企业如何实施主流化策略提出了建议。
