跨国垄断在中国:现状、影响及规制

该文通过统计数据和案例分析认为跨国垄断已经在中国发生，并指出存在着两种不同类型的跨国垄断，即跨国企业整体垄断某个行业和单个跨国企业垄断整个行业；进而分析了两种不同形态的垄断对经济造成的不良影响。最后，探讨了如何防范和规制跨国垄断，认为防范跨国垄断要从多方面着手，除了最重要的竞争政策手段以外，还必须在反垄断法中加强对跨国垄断的规制。     

Bridging inter- and intra-firm boundaries: management of supplier involvement in automobile product development

Outsourcing has become an important strategy for many firms. Yet, firms need to compete with their competitors who also outsource and may share the same suppliers. This article explores how a firm could outperform others in managing the division of labor with a supplier in product development. Drawing on the empirical data collected from the Japanese auto industry, this paper shows that an automaker needs capabilities to coordinate various activities both externally with a supplier and internally within its own organization, in order to gain better component development performance. Overall, the results imply that outsourcing does not work effectively without extensive internal effort. Copyright © 2001 John Wiley & Sons, Ltd.

Tourism as an alternative source of regional growth in Portugal: a panel data analysis at NUTS II and III levels

The role of tourism is of vital economic importance, particularly for small countries with a privileged geographical location and favourable weather conditions. This paper examines the importance of tourism as a conditioning factor for higher regional growth in Portugal by employing the conditional convergence hypothesis of Barro and Sala-i-Martin, associated with the endogenous growth theory. The panel data estimation approach provides evidence of the positive impact of tourism (through the accommodation capacity) on the growth in per-capita income among the Portuguese regions, increasing the rate of convergence. Therefore, tourism can be considered as an alternative source for stimulating higher regional growth in Portugal, if the supply characteristics of this sector are improved.     

Research notes and communications strategic planning as competitive advantage

Since 1970, over forty empirical studies have examined the performance consequences of formal strategic planning. This line of research has drawn heavy criticism from reviewers on methodological grounds, and has produced confusing, apparently contradictory results. This article reevaluates the planning-performance relationship from a resource perspective, arguing that strategic planning does not satisfy the criteria for sustainable competitive advantage– although it may produce economic value, it is easily imitated and may be substitutable. The article suggests that previous studies produced inconsistent results because they did not account for the dissemination of strategic planning over time, or for industry differences in strategic planning factor markets. An empirical test in two industries finds that formal strategic planning and financial performance are unrelated in a ‘planning equilibrium’ industry, but positively related in an industry with strategic planning factor market imperfections.

Average Monotonic Cooperative Games

A subclass of monotonic transferable utility (T.U.) games is studied: average monotonic games. These games are totally balanced. We prove that the core coincides with both the bargaining set à la Davis and Maschler and the bargaining set à la Mas-Colell. To obtain this result a technique based on reduced games is used.

Does an Industry Effect Exist for Initial Public Offerings?

We examine the impact of initial public offerings (IPOs) on rival firms and find that the valuation effects are insignificant. This insignificant reaction can be explained by offsetting information and competitive effects. Significant positive information effects are associated with IPOs in regulated industries and the first IPO in an industry following a period of dormancy. Significant negative competitive effects are associated with larger IPOs in competitive industries, those in relatively risky industries, those in high‐performing industries, and those in the technology sector. IPO firms that use the proceeds for debt repayment appear to represent a more significant competitive threat to rival firms relative to IPO firms that use their proceeds for other purposes.     

Does success diminish competitive responsiveness? Reconciling conflicting perspectives

Previous research provides conflicting evidence of the association between the past performance of a business and its competitive responsiveness, with researchers observing both positive and negative relationships. To clarify this issue, the authors test a model using survey data from the retailing industry. The model delineates direct and indirect mediated paths through ability to respond, motivation to respond, and awareness of competitors’ actions to show how past performance can have both positive and negative influence on competitive responsiveness. However, the overall impact of past performance of an organization on its competitive responsiveness is positive. The implications of these findings for research, practice, and theory are discussed.
