On the evolution of the spatial economy with multi-unit · multi-plant firms: the impact of IT development

This paper examines how the decline of communication costs between management and production facilities within firms and the decrease in trade costs of manufactured goods affect the spatial organization of a two-region economy with multi-unit·multi-plant firms. The development of information technology decreases the costs of communication and trade costs. Thus, the fragmentation of firms is promoted. Our result indicates that, with decreasing communication costs, firms producing low trade-cost goods (such as electronics products) tend to concentrate their manufacturing plants in low wage countries. In contrast, firms producing high trade-cost products (such as automobiles) tend to have multiple plants serving to segmented markets, even in the absence of wage differentials.Received: November 2004, Accepted: March 2005, JEL Classification: F12, L13, R13Masahisa Fujita: Correspondence toWe are very grateful to J.

Impeding insurgent attacks: The information management agenda

Recent confrontations in Iraq between coalition forces and insurgents have caused much havoc in the way of economic and political reforms. Insurgents use a wide range of tactics, from suicide bombings to kidnappings, to cause tension between the local factions and the Iraqi populace, and between the locals and the coalition forces. The strength of the insurgent strategy emerges from the nature of their attacks: highly erratic, yet potent. All-out-assault on these insurgents is impossible as they cloak themselves and exploit the advantages of guerrilla warfare tactics. In this paper, we will highlight the informational issues that the coalition forces must appreciate in order to curb and curtail these insurgent attacks. While we do not aim to propose any grand strategy to eradicate all insurgent attacks, we do believe that the true weapon that needs to used optimally (effectively and efficiently) against such attacks is information. Whether the insurgents or the coalition forces, the side that is more successful at managing and deploying information potently and with intent will ultimately prevail.     

An environmental performance index for products reflecting damage costs

Several studies have demonstrated how to use DEA (Data Envelopment Analysis) based techniques to estimate environmental performance indices. None of these studies, however, are taking information on the environmental damage costs of the pressure types considered into account. This study is bridging a gap between environmental indices founded in physical pressures and damage costs founded in welfare economics. The aim of the paper is twofold: first, to demonstrate how to implement the information on environmental damage costs within a DEA based environmental performance index, and second, to estimate these indices at product level by using Danish input-output data and environmental data from 1997.     

Groupware adoption in a distributed organization: transporting and transforming technology through social worlds

In this paper, we draw on theory from social worlds to analyze how different organizational contexts affect groupware adoption. We report on a study of the adoption of data conferencing in a large distributed organization. Our data show that the diffusion process, which was driven by the users, was a result of communication and transformation of the technology across different social worlds. We also discovered that membership in multiple social worlds in an organization creates a tension for the potential adopter who is in a distributed team. To function effectively, team members must uniformly adopt the technology, yet some may face resistance from other social worlds to which they belong. Our study showed that adoption was affected by organizational sites having conflicting views of the value of collaboration, different amounts and needs for resources, and different acceptance of technology standards. Potential technology adopters on distributed teams are faced with conflicting loyalties, constraints, and requirements between their distributed collaborations and organizational homes.

Technological forecasting at the Korean stock market: A dynamic competition analysis using Lotka–Volterra model

The purpose of this paper is to attempt to analyze the dynamic relationship between the Korean Stock Exchange (KSE) and Korean Securities Dealers Automated Quotation (KOSDAQ), two competing markets at the Korean stock market, in the viewpoint of technological forecasting of competition. The Lotka–Volterra system of equations, one well-known competitive diffusion models, is adopted to represent the competitive situations of the Korean stock market and it is estimated using daily empirical index data of KSE and KOSDAQ during 1997–2001. The results show that there existed a predator–prey relationships between two markets in which KSE acted as a prey for the time being after the emergence of KOSDAQ. This interaction was altered to symbiotic relationship and finally to pure competition relationship. We also perform an equilibrium analysis of the estimated Lotka–Volterra equations. As a result, we find that there is an equilibrium point in a dynamic sense. However, the equilibrium point could be unstable in the latest pure competition relationship.     

应收账款成因与对策的理论研究

企业的资产质量是评价一个企业的重要指标,也是企业生存发展的重要保证。应收账款是企业的一项流动性较差的资产,分析应收账款形成原因是治理应收账款的重要前提,传统观点主要从扩大销售提高市场占有率方面对应收账款进行分析。本文结合经济发展的新形势从全新的角度对应收账款进行了分析,并据此提出了治理对策,以供探讨。
