The emergence and market success of Linux in recent years has been impressive. The paper investigates the question of why some producers of a proprietary software support the development of open source software (OSS) while others refuse any support. As an analytical framework, a simple Launhardt–Hotelling model is used to show that the emerging price pressure on the former monopolists depends on the extent of the current heterogeneity between OSS and the proprietary software of the incumbents. The paper argues that the product heterogeneity can explain the differing real-world behavior of commercial software producers. 相似文献

This paper argues in favor of open regionalism and continent-based integration in Asia. These are the effective instruments of outward-oriented development. The enlargement of trading blocs into continent-based integration also serves as a countervailing power to stem the excesses of economic globalism. The case made in the paper shows the need for institutional changes for promoting economic development. Institutional changes along with open regionalism are essential to enhancing outward-oriented development in South Asia. Respectable progress has been made in these areas across the continents in general, and in Asia in particular (ASEAN, SAARC, APEC). Efforts on these initiatives must be redoubled as we start the 21st century. 相似文献

This paper shows that abnormal stock price returns around the date of open market repurchase announcements are four times higher in Germany than in the USA (12 ver. 3%). We hypothesize that this observation can be explained by national differences in repurchase regulations. Our empirical evidence indicates that German managers primarily buy back shares to signal an undervaluation of their firm. We demonstrate that the stringent repurchase process prescribed by German law attributes a higher credibility to undervaluation signals than do the lax US regulations, and thereby corroborates our hypothesis.Financial support from the E-Finance Lab, Frankfurt am Main, and from Freitag & Co., Frankfurt am Main, is gratefully acknowledged. We would like to thank two anonymous referees for their helpful comments 相似文献

This article reports on the economic implications to the USA and Western European economies after imposing protectionist trade policies on selected groups of imports till 2000. The effects of this policy are also presented for Japan and the non-oil-producing developing countries. Before discussing the results of the computations and the import restricting assumptions, a summary of the methodological framework, the World Input-Output Model, used in the computation is presented. 相似文献

This paper discusses how firms develop and use resources across a permeable project boundary and conceptualizes how a project can create value for a focal parent organization. Inspired by ideas on interaction and open innovation, we suggest a framework for analyzing the flow of resources based on the two dimensions; direction, whether the resource starts inside or outside the project, and mode, whether the resources cross the boundary once (uni-directionally) or twice (bi-directionally). The dimensions lead to four situations: Inside-out, Outside-in, Boomerang and Passing on. The framework is based on a single case study of an inter-organizational research project in plant biotechnology in a Swedish context. Through these four situations, the results show that a focal parent organization can create direct, indirect, relational potential and transactional potential value. The complex pattern of value creation in an open network context, raises the challenging question of how to capture the value created. 相似文献

在网络社会的背景下,伴随着网络通讯技术的发展,消费者的角色及行为发生了变迁,消费者具有了消费者和生产者的双重属性。"产消者"的兴起正在重塑着经济生产主体与生产方式、企业创新模式与组织模式,是社会经济结构的一种变革。文章将"产消者"模式分为用户生成内容和消费者承担价值链环节两种形式,分析了"产消者"兴起的动因和理论内涵,认为我国政府与企业需顺应与推动"产消者"的发展趋势,激励消费者参与到研发、生产和营销等价值链环节中,支持消费者参与和监督产品的生产与交易,实施基于"产消者"共同创造价值的管理创新。 相似文献

城市社会在对农民的开放与封闭之中徘徊。改革开放后城市社会对农民的开放已经使很多农民城市化。城市社会对农民的封闭已由政策性封闭转向经济性封闭。城市社会对农民的封闭增加了农民城市化的成本和社会风险。必须加强城市社会对农民的开放,逐步消除对农民的封闭政策,以推进农民的城市化。 相似文献

Order aggressiveness and order book dynamics 总被引:2,自引:0,他引:2
In this paper, we study the determinants of order aggressiveness and traders’ order submission strategy in an open limit order book market. Applying an order classification scheme, we model the most aggressive market orders, limit orders as well as cancellations on both sides of the market employing a six-dimensional autoregressive conditional intensity model. Using order book data from the Australian Stock Exchange, we find that market depth, the queued volume, the bid-ask spread, recent volatility, as well as recent changes in both the order flow and the price play an important role in explaining the determinants of order aggressiveness. Overall, our empirical results broadly confirm theoretical predictions on limit order book trading. However, we also find evidence for behavior that can be attributed to particular liquidity and volatility effects.

新贸易保护主义的特征演变及其理论依据 总被引:10,自引:1,他引:9
新贸易保护主义是特指二战以来西方发达国家的各种贸易保护理论及其政策措施。20世纪90年代以来,新贸易保护主义原有的特征产生了一些变化,表现为更多地寻求多边贸易体系下的合法性保护;对进口保护的重新重视;从非关税措施的明显性保护转向隐蔽性保护;从单纯贸易政策转向经济、竞争政策,这些演变背后存在众多的理论支持,研究这些演变及其理论依据具有重要的理论与现实意义。 相似文献
