This study attempts to identify firm characteristics that explain the disparity between the information content of accounting earnings and stock prices. Granger's causality concept was employed to classify sample firms into four groups: price-leading firms, feedback-system firms, earnings-leading firms, and no-causation firms. The feedback-system firms were either combined with the no-causation firms or eliminated entirely to form three sample groups. The entire sample firms then were divided into two classes. The first is for estimation, and the second is for prediction. Results indicate that firm size, capital structure, R-square of regressing prices at time t against earnings at time t – 1, R-square of regressing earnings at time t against prices at time t – 1, and percentage of shares held by institutions are the significant explaining variables. The application of the coefficient estimates to the hold-out sample indicates that 76.2% of the firms can be correctly classified into the corresponding groups. These results were consistent with those from canonical discrimination and other multivariate statistical methods.  相似文献

This article studies the shareholder wealth effects associatedwith 875 new security issues in Japan from January 1, 1985,to May 31, 1991. The announcement of convertible debt issueshas a significant positive abnormal return of 1.05 percent.There is an abnormal return of 0.45 percent at the announcementof equity issues that is off-set by an abnormal return of 1.01percent on the issue day. Abnormal returns are negatively relatedto firm size, so that large Japanese firms have abnormal returnsless different from those of U.S. firms than small Japanesefirms. Our evidence is consistent with the view that Japanesemanagers decide to issue shares based on different considerationsthan American managers.  相似文献

模块化:系统结构与竞争优势   总被引:14,自引:0,他引:14  
从物理模块、处理模块到价值模块,联系媒介、标准和性质趋向抽象领域和独立自由;从大型电脑、个人电脑到互联网模块化,硬件模块之间关系通过软件实现模块化,使模块化结构更加开放。模块系统利益结构由规模经济、局部经济与范围经济的对立转向规模经济、差异经济与网络经济的兼容,超级模块化和数码化是其关键;市场竞争、产权保护和金融选择等模块化利益机制推动了企业经营目标、模块化动力和模块创新模式演变。模块化不但有来自模块设计、模块化设计、“行路图”设计和组织模块化设计等自身竞争优势,也有来自数码化、创新文化、科学商业化和政府政策等环境竞争优势。  相似文献

Innovation capital are typically expensed and/or unrecognized as assets under current generally accepted accounting principles. This results in accounting-related information asymmetry. This paper examines the association of innovation capital (as measured here by the proxies of R&D expenditures and granted patents) and initial public offerings (IPO) anomalies. These anomalies include initial IPO underpricing, duration of honeymoon (a distinct feature of the Taiwanese IPO environment), and long-term performance. The theoretical model underlying this research is a signaling model. The results indicate that more innovative firms are more likely to be underpriced, and have longer honeymoon periods than less innovative firms. Further, the more innovative firms have positive and growing long-term market-adjusted returns. This stands in contrast to the declining long-term stock performance of initial public offering firms that is evidenced in the literature. We conclude that pre-IPO research and development expenditures disclosed in the IPO prospectus, official monthly reports of newly developed patents released to the public, and the frequency of patent citations significantly signal both underpricing and future market performance of IPO firms in Taiwan.  相似文献

On July 13, 2006, the Min istry of Information Indus try of the People's Repub lic of China ("MII") issued a new notice concerning foreign-invested telecom and internet companies in China. MII's "Notice on Strengthening Regulation of Foreign Investment in and Operations of Value-Added Telecom Services" (the "MII Circular"), further clarifies the existing regulatory framework governing foreign investment in internet and other value-added telecommunications (" VATS ") businesses in China.  相似文献

The aim of this work is to examine the dimensions of satisfaction in manufacturer-distributor relationships as well as identifying the antecedents of both the economic and the non-economic dimensions of satisfaction. A literature review about satisfaction in marketing channels is followed by quantitative research into how this interchange process is perceived by food product distributors in their relationships with manufacturers. The results provide strong support for the impact of communication, trust and commitment on satisfaction, as well as the interrelationships among the economic and the non-economic dimensions of satisfaction. Theoretical and managerial implications are extracted from these findings.  相似文献

This paper first defines and then presents a model of “relationship equity” for business markets. It points out that the potential benefits of managing relationship equity have been largely ignored and that a general model and stream of relevant research questions could be useful to marketing and relationship practitioners. The model developed considers the special case of key account management as antecedent, two different types of moderator variables, relationship equity as a perception by the buyer, and switching behavior via adoption of new telecommunication services as a result of this perception. The model is used as a basis for developing a number of working propositions.  相似文献

Organizational norms as a set of embedded values and beliefs have long been recognized in literature to provide norms that bind individuals into collectivities. Drawing on resource dependence and relational marketing theories, the present study specifies five organizational norms: cooperative, cross-functional information sharing, intraorganizational knowledge sharing, participative culture and mutual trust for supporting cross-functional coordination in supply chain management (SCM). These organizational norms are examined in terms of the mediating role of cross-functional coordination for the relationship between organizational norms and supply chain performance. Analyses of data from a survey of high-tech firms in the U.K. substantiate that organizational norms impact on both supply chain responsiveness and firm performance through cross-functional coordination as a mediator. The implications of the positive effect of organizational norms on SCM performance are discussed for theory, practice and research.  相似文献

Among the growing literature on value creation in collaborative buyer-seller relationships, most researchers examine relationship value at a single point in time. In the present research, we explore whether different stages of the relationship life cycle moderate the relative importance of value-creating dimensions. To shed light on the dynamic nature of value in B2B relationships, we present the results of a survey among purchasing managers using a quasi-longitudinal research design. Our findings confirm the moderating role of the relationship life cycle in value creation. More precisely, our results indicate that a key supplier's potential for value creation in customer's operations increases in relative importance as relationships move through the life cycle. In turn, supplier's capabilities to create superior value at the level of the customer's sourcing process display a decreasing role over the life cycle of a business relationship. No significant link was found in the present study between value creation through a supplier's core offering and different stages of a buyer-seller relationship.  相似文献
