债权人权利保护法律颁布的市场反应——基于法和金融理论的研究

法律对银行债权人权利的保护可以通过书面法律的制定及完善得以实现。那么,债权人权利保护法律的颁布和修订是否会引起市场投资者的反应?文章运用事件法考察了《物权法》、新《公司法》和新《企业破产法》的颁布和修订对我国上市银行股价的影响。研究结果表明,三部法律公布事件对上市银行的股价均有显著的冲击效应,这说明债权人权利保护法律的颁布和修订引起了市场投资者强烈的反应;进一步地我们发现,不同法律事件下不同银行的股价所受影响各异,这可能源于上市银行的终极控制人以及三部法律关于债权人保护条款的侧重点和法律规定的强度不同。     

Abnormal returns before acquisition announcements: evidence from Europe

Acquisition announcements influence the stock price of target firms, providing an opportunity for insiders to obtain significant abnormal returns. We study the presence of positive abnormal returns before the announcement date, in target firms, quoted in Euronext markets (Belgium, France, The Netherlands and Portugal) from 2001 to 2007. We investigate whether the pre-announcement run-up of prices can be explained by rumours in the media and the percentage of capital previously owned by the bidding firm, among other factors. We examine cumulative abnormal returns in an event window of 60 days prior the acquisition announcement, with the event date adjusted for the previous disclosure of news about the acquisition, in the media. We compute a run-up index, and find that there are abnormal positive returns before the announcement date, confirming previous studies. We find that a significant part of the run-up is explained by: (i) market anticipation triggered by legitimate sources of information, namely, rumours in the media about the possibility of an acquisition bid and (ii) the percentage of capital previously owned in the target firm, by the bidding firm.     

The effects of multilateral trading systems on risk and return in equity markets

The event study methodology of Brown and Warner (1985) is adopted and augmented to evaluate the effect of the launch of multilateral trading systems on risk and return in equity markets. The methodology is supplemented with various techniques, such as the nonparametric ranking test and kernel regression, to find out if announcements about the introduction of Chi-X Australia generated abnormal returns (ARs). Asset pricing models are fitted with interaction variables, while GARCH, threshold ARCH (TARCH), exponential GARCH (EGARCH) and power-ARCH (PARCH) are used to determine changes in systematic risk. We find evidence in favour of Fisher’s separation theorem and detect a new market anomaly, which we call the ‘Fisher market anomaly’. Our results show that Chi-X system testings affect ARs. Consistent with the adaptive expectations theory, we confirm that the first announcement about the launch of Chi-X affected systematic risk the most. In addition, we identify industry and firm effects in risk analysis.     

Firm Organization,Technology And Performance: An Empirical Study ∗

The purpose of the study is to characterize different styles of work organization in French firms and their current changes and to link them to the use of specific technologies and to firms performance. The data which are used arc of two kinds: a labor force survey (1 470 blue collar) and a business survey (7 089 firms). We show that two main variables create differences among firms' organization devices: the intensity of communication within the workshop and the level of autonomy of workers (facing technological and hierarchical constraints). The use of advanced technologies and the skill of the labor force are positively linked to both organizational variables. Therefore. ‘Communicating organization’ and organizational innovation seem to aim at creating conditions for individual and collective learning on new technologies. They also enhance the ability of the firm to adapt to changing market conditions through technological innovation and inventory reduction, These views are supported by econometric estimation.     

The framing of product ideas in the making: a case study of the development of an energy saving pump

Research regarding work with ideas in industrial settings has predominantly treated ideas as rather stable ‘black boxes’. This article contributes a new understanding of idea work and seeks to expand our understanding of how a product concept is constituted and synthesised through socio-material interaction of organisational members and engagement in idea work. The article contributes a case study of the development process behind the energy-saving Alpha Pro circulator launched by the Danish pump manufacturer Grundfos. Based on an analysis of how organisational players engage in the controversial and shifting understandings of what seems to constitute a successful product, the article offers a new perspective on navigating the players’ ideas in the political processes of innovation. It suggests that navigation of technological frames can offer a new perspective to make explicit the implicated actors’ world views, including what they perceive as relevant problems and related strategies for solving them.     

From peripheral to core: a case study of a 3D printing firm on business ecosystems reconstruction

ABSTRACT

The rapid development of emerging digital technologies is giving peripheral firm, which is participant in secondary and complementary positions in a business ecosystem, unprecedented opportunities to shape its own ecosystem. Prior ecosystem studies mainly focus on the perspective of core firm, while few taking the perspective of peripheral firms. Using the case of a leading 3D printing firm in China, this study adopts resource orchestration as theoretical lens and investigates how a peripheral firm developed its business ecosystem and became a core firm in its own digital ecosystem. Specifically, this study identifies three stages of ecosystem development and the detailed processes and mechanisms, respectively. It contributes to the literature by exploring the ecosystem dynamics from an understudied perspective and identifying the processes and mechanisms of peripheral firms developing its ecosystem towards digital ecosystem. It also sheds lights for peripheral firms in existing business ecosystems in their business strategy development.

Caste,Kinship, and Life Course: Rethinking Women's Work and Agency in Rural South India

This paper reexamines the linkages between women's work, agency, and well-being based on a household survey and in-depth interviews conducted in rural Tamil Nadu in 2009 and questions the prioritization of workforce participation as a path to gender equality. It emphasizes the need to unpack the nature of work performed by and available to women and its social valuation, as well as women's agency, particularly its implications for decision making around financial and nonfinancial household resources in contexts of socioeconomic change. The effects of work participation on agency are mediated by factors like age and stage in the life cycle, reproductive success, and social location – especially of caste – from which women enter the workforce.     

Information technology developments of logistics service providers in Hungary

The objective of this research is to examine the role of sector-specific information technology (IT) developments and their significance in terms of the revenue and earnings before tax of Logistics Service Providers (LSPs), as well as the impact of these developments on the flexibility and integration of LSPs. A survey questionnaire was conducted with 284 LSPs participants. The data provided by the 51 responding enterprises provided a representative sample for the analysis of the sample population and the drawing of general and relevant conclusions related to basic population. It can be concluded that their revenue, earnings before tax and degree of integration into the supply chain depend on the sector-specific IT developments carried out by the given enterprise. IT investments will remain important in the future and the introduction and leveraging the best technologies may yield competitive advantages and higher financial rewards for LSPs.
