Industrial distributors: Can they survive in the new economy?

As e-commerce evolves and gains power in the business-to-business (B2B) marketplace, what lies ahead for the industrial distributor? The fundamental issue from the distributor's point of view is how to compete more effectively and profitably, given the changing business environment of the new economy. This paper reviews the literature on the distributor's role and relationships and introduces a conceptual model of distributor viability. The model identifies sources of value that distributors offer to manufacturers and customers, including customer relationship management (CRM), production and operations management (POM), and knowledge management (KM). The paper explores the managerial implications of distributor relationships and sources of value. This provides the foundation for better understanding of the viability of industrial distributors in the new economy.     

Strategizing in industrial networks

This paper provides an overview of the implications for strategizing offered by an industrial network perspective and a comparison of this view with strategic management thinking. We argue that it is crucial for a company to relate its activities to those of other firms in order to enhance its performance, and it is through the continuous combining and recombining of existing resources that new resource dimensions are identified and further developed within business relationships. From the standpoint of a single company, strategizing from an industrial network perspective implies that the heterogeneity of resources and interdependencies between activities across company boundaries, as well as the organized collaboration among the companies involved, must be considered simultaneously.

Dynamic volatility and external security related shocks: The case of the Athens Stock Exchange

This paper analyses the impact of exogenous national security related shocks on the time-varying volatility structure of the Greek stock market. Alternative autoregressive conditional heteroscedastic models are estimated, in order to identify the best fit that adequately describes return volatility behavior, testing symmetric as well as asymmetric innovation responses. An external national security related shock factor is included as well as a military crisis dummy, in order to depict possible implications for the conditional variance. The empirical findings appear to support a statistically significant impact of both national security related factors on the Athens stock market returns.

论中国的石油安全问题

目前，石油问题引起了业内各界人士的普遍关注，关于石油战略储备的话题沸沸扬扬。中国石油能源面临的主要问题，并不是世界石油资源的短缺或长期供应能力不足；也不是由于政治、军事冲突而对我国可能实行的石油禁运，中国石油能源面临的最大问题是中东地区突发事件引起的国际油价波动，以及其他国家间的重大冲突造成短期石油供应受阻而波及中国。我国的当务之急是尽快建立石油战略储备体系，而且应根据我国的生产和消费状况确定合理的储备规模和储备方式。
