竞争力、市场微观结构与证券交易所变革 总被引:1,自引:0,他引:1
纽约证券交易所和纳斯达克实施的重大并购行动标志着全球证券交易所新一轮并购浪潮的兴起,证券交易所之间的竞争再度趋于白热化.交易所之间的竞争已演变为市场微观结构的竞争.本文对纽约证券交易所和纳斯达克的交易成本进行了比较,无论是上市成本还是交易成本,新兴的纳斯达克都比传统的纽约证交所更胜一筹.因而本文认为有效降低交易成本应是提高交易所核心竞争力的关键所在,而改进交易机制、拓展产品服务以及调整组织架构,可以作为降低交易成本、提高交易所竞争力的具体竞争策略. 相似文献

Asymmetric Network Interconnection 总被引:1,自引:0,他引:1
We develop a model of competition between interconnected networks,that allows for carriers to differ in size. Under two-partpricing, we show that because of asymmetry the larger network willalways prefer a reciprocal interconnection charge be set at cost.For sufficiently large asymmetry the smaller network will have thesame preference. Under the assumptions of our model a particularly simple regulation is optimal – if carriers cannot agree on the terms of interconnection, the larger carrier is entitled to select the access price which is then applied reciprocally. 相似文献

项目总控的应用及其信息处理规划 总被引:1,自引:0,他引:1
随着国内大型建设项目的增多,大型建设项目的实施遇到诸多问题,其原因主要是业主对项目的控制能力不强,从而导致大型建设项目不能实现其质量、进度、投资等预期目标,甚至会导致整个项目的失败,项目总控模式的应用很大程度地解决了这一问题,另外,由于信息处理是项目总控的主要工作,因此,本也讨论了项目总控模式下的信息处理规划。 相似文献

Joint value creation through partnering and networking is a topic of current interest. This paper proposes that the dimensions of the supplier's value creation in a supplier-customer relationship could be classified according to efficiency, effectiveness and network functions. These functions are interrelated, but they are conceptually distinct. The value creation process could be described as a spectrum ranging from core value, to added value, to future value. The value-producing potential of a supplier can be assessed reasonably well only in the case of the core value, where there is sufficient benchmarking information in the form of existing alternative offerings and solutions. A priori evaluation of the costs and benefits of added value and, especially, future value projects is problematic, because the realisation of the value is dependent on the development of multiple partners, technologies and industries. In these cases, we suggest that a customer could use a supplier's capability profile as an indicator of how suitable that particular supplier is for specific value creation projects. A framework connecting specific capabilities to different types of value production is suggested, and its managerial implications are discussed. 相似文献

Strategizing in industrial networks 总被引:1,自引:0,他引:1
Lars-Erik Gadde Author Vitae Author Vitae Håkan Håkansson Author Vitae 《Industrial Marketing Management》2003,32(5):357-364
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. 相似文献

Estimates of central bank intervention losses or profits vary widely; some estimates find substantial losses, others profits. In most cases, estimated profits are not risk-adjusted, and risk adjustment can have large effects. Furthermore, profit estimates involve variables integrated of order one, and because of this test-statistics may have nonstandard distributions; few studies take this into account. Estimates of risk-adjusted profits for the US Fed and the Swedish Riksbank, with allowances for possible nonstandard distributions, suggest that neither made losses and might have made significant profits. 相似文献

In this article, the traditional price change hedge ratio estimation method is extended by applying the theory of cointegration in the case of cross-hedging of spot exchange risk of the Belgian franc (BF), the Italian lira (IL), and the Dutch guilder (NG) with U.S. Dollar Index futures contracts. Previous studies ignore the last period's equilibrium error and short-run deviations. The findings of this study indicate that the hedge ratio estimated by the error correction method is superior to that obtained from the traditional method, as evidenced by the likelihood ratio test and out-of-sample forecasts. Hedgers will be able to control the risk of their portfolios more effectively at a lower cost. 相似文献

金融工程具有对风险的规避和放大效应。金融工程的发展不仅需要强大的技术手段支持,更需要政府从制度层面进行合理配置。本文分析了金融工程在经济运行中的负面作用,根据当前我国利率、汇率市场化改革的宏观环境,并结合当前国外金融制度建设的基本特征和我国基本国情,提出了我国金融工程发展的制度框架。其中,近期制度建设构想为:加强法规制度建设,优化金融环境,严防金融欺诈;加强监管机构管理,确保其独立性和公平性;加强二级市场管理建设。远期制度建设构想为:进一步强化对产品发行人、合作投资计划、市场中介机构和行业自律等方面的制度约束。 相似文献

任何汇率制度都只是实现经济目标的手段而不是目的,我们在各个时期选择的汇率制度应该是对我国经济发展最有利的制度。在现有的国际货币体系下,如果资本项目尚未开放,则理性的选择应该是固定汇率制度;如果资本项目已完全开放,则实行浮动汇率制是有效而保险的。对于中国这样一个资本账户部分开放的国家,现阶段重新回到真正意义上的有管理的浮动汇率制是必要的,也是可行的。 相似文献
