Strategizing through analyzing and influencing the network horizon

How does a firm keep on being valuable in a network? One requirement is that the firm has a sufficient overview of the network and its dynamics. In other words, a firm's strategy depends on the firm's overview of the network—its network horizon. How comprehensive or limited should its network horizon be? Is it necessary to know the network beyond the direct counterparts? Such issues have not received much attention. In this article, we discuss network horizons and argue that limited network horizons are both inevitable and useful. However, such myopia requires that a firm's counterparts effectively and efficiently mediate between the firm and the rest of the network. Based on a case study, we introduce and discuss three mediating functions of counterparts: a joining, a relating, and an insulating function, and we claim that in order to support a firm's strategizing, managers need to analyze and influence counterparts' mediating functions and thereby the firm's network horizon.

Network neutrality and the nature of competition between network operators

The neutral architecture of the Internet is being challenged by various parties, such as network operators providing the connections to end-users, who are interested in gaining control of the information exchanged over the Internet. What are the effects on competition and welfare of such practices? Currently, there exists very little economic theory on network neutrality. This paper provides a preliminary analysis of the type of economic modeling that can address network neutrality, as well as of the type of results that can be expected.     

AN EMPIRICAL EXAMINATION OF RELATIONSHIP MAGNITUDE

Based upon a review of the extant literature, it is proposed that the structure of an interorganizational relationship is composed of relationship type and the under‐researched construct of relationship magnitude. Specifically, it is hypothesized that relationship magnitude, a second order construct composed of trust, commitment, and dependence, affects relationship type, which affects the perception of value of the relationship. The results of a survey analyzed through structural equation modeling support these hypotheses.

具有网络效应的产品的价格竞争分析

具有网络效应的产品是指消费者在消费这种产品时所获得的效用会随着购买这种产品的其他消费者数量的增加而不断增加的产品。本文通过建立一个有两个厂商的离散动态决策模型，研究在分散决策的市场经济中生产具有网络效应的产品的厂商的价格决策对产品市场占有率的影响，价格决策影响产品市场占有率的动态演化的过程，以及市场均衡的务件和特征，包括产品不占有市场、占有部分市场以及上有今都市场的价格条件。

中国城市住宅市场的结构差异性分析

市场价商品房、经济适用住房和廉租房构成了目前中国城市住宅市场的供应体系.依据中国30个主要城市的房地产开发统计数据,选择吸纳率作为评价住宅市场供需均衡状态的指标,利用固定影响变截距模型,重点研究了商品房和经济适用住房供给结构的城市差异性.研究发现,在城市住宅市场中,经济适用住房市场和商品房市场具有很强的相关性.作为具有政府资助性质的经济适用住房建设,存在典型的地域性特征,其政策的设定和实施会对整个住宅市场产生影响,地方政府应在利用比较全面的住宅市场指标体系进行综合分析基础上,制定适合本地的经济适用住房政策.     

利率风险与债务期限结构的正反馈效应分析

本文在总结以前学者有关债务期限结构分析的基础上,提出了债务期限结构与利率波动之间可能存在正反馈机制。通过对经筛选的我国上市企业面板数据的实证分析,发现银行间同业拆借利率可以较好地反映企业债务期限结构的变化。而分行业的实证分析则表明,利率波动加剧会使绝大多数行业的短期债务比例降低,呈现显著负相关关系。但现阶段我国的利率形成受企业债务期限结构变化的影响不明显,长短期的面板Granger因果检验无法通过。最后,本文从利率风险及利率期限结构的角度对我国上市公司特殊的债务结构给出了新的解释。
