The effect of external supply knowledge acquisition,development activities and organizational status on the supply performance of SMEs

Given the increasingly strategic role of external resources, acquiring knowledge about current suppliers and the broader supply market is an important and demanding task for the purchasing and supply management (PSM) function of a firm. Performance-improvement-oriented application of external supply knowledge present further challenges for the function. To examine this, we draw on the knowledge-based view and develop a hypothesized model in which supply knowledge acquisition drives PSM exploration and exploitation orientations which in turn mediate the organizational status of PSM function in terms of supply performance. We test the model on an SME-focused and survey-based dataset, using structural equation modelling. Our results indicate that an exploitative orientation is associated with knowledge gained from the supply base, whereas an explorative orientation is predominantly associated with supply market knowledge and less with supply base knowledge, suggesting natural pairings. The findings also show how an exploitative development orientation mediates the positive association of the PSM function's organizational status with supply performance. Driven by supply base knowledge, a status-empowered exploitative PSM orientation may suppress supply market based explorative orientation in resource-scarce SMEs, thus appearing to serve as the sole path to supply performance. Our research contributes by pointing out the significance of the knowledge-resource, and the knowledge-based view, in understanding performance in PSM.

Are We Better Off if Our Politicians Have More Information?

The model of public policy studied in this paper has heterogeneous citizens/voters and two public goods: one (roads) chosen directly by an elected policy‐maker, and the other (pollution) stochastically dependent on the amount of roads. Both a one‐country and a two‐country version of the model are analyzed; the latter displays externalities across the countries which create incentives for free riding and strategic delegation. The welfare effects of providing the policy‐maker with information about the relationship between roads and pollution are investigated, and it is shown that more information hurts some—sometimes even all—citizens. In particular, the opportunity not to create an institution for information gathering can serve as a commitment device for a country, although with the unfortunate effect of making the overall outcome even worse. Implications for the welfare effects of “informational lobbying” are also discussed.     

Monopoly, competition and information acquisition

An incumbent monopolist is uncertain about its linear demand, but can acquire public information at a cost. We determine how an entry threat affects the firm's information acquisition. If returns to scale are constant and the state-contingent demands become more dispersed as output increases, then entry reduces information acquisition. If, however, either the incumbent or entrant has increasing returns; or if the state-contingent demands are nonlinear or fail increasing dispersion, then entry can increase information. Finally, entry can hurt consumers. Although entry always increases output, it can decrease information. Consumers sometimes prefer a better informed monopoly to a duopoly.     

中国企业海外并购的特点及成因分析

进入21世纪后，我国企业掀起了海外并购的浪潮，在这次并购浪潮中表现出并购总额持续上升、单宗交易额不断增大、并购行业向多方面扩展、并购主体多元化等新的特点。这次并购浪潮形成的原因主要有：我国经济实力的增长、我国企业对战略性资源的渴求、人民币的持续升值、外汇储备的快速增长、国家政策的转变、全球产业结构的调整等。

制约上市公司并购的外部因素及对策

随着我国证券市场的建立,上市公司并购出现快速发展的趋势,但同时存在着制约其发展的一些外部因素。本文建议,应建立健全相关并购法规,减少政府干预,完善证券市场机制及拓宽并购融资渠道,加强与规范中介机构在并购中所起的作用,以推动上市公司并购的健康发展。     

并购行业模式对企业价值创造的影响

以1998～2004年A股非金融类上市公司发起的并购重组事件为样本，通过实证考察并购行业模式与收购企业价值之间的因果关系，证实我国上市公司实行行业相关性并购较无关性并购对收购企业具有更强的价值创造效应。同时，将对应于企业价值指标、有关并购价值创造的经济学假设分解成五类财务因素指标，通过比较不同并购模式下收购方指标变动特征的异同，揭示出规模经营、交易内部化和市场势力是影响收购企业价值的主导因素。
