This paper investigates whether the announcement and/or the implementation of the major changes in March 2003 to the German stock index landscape led to significant price and volume effects. We examine five stock subgroups that were either removed from their former indices or that were added to existing or newly constructed indices. Around the announcement date, stocks in these groups are subject to (cumulative) positive average abnormal marketadjusted returns, whereas the average trading volume tends to decrease. Around the actual change date, (cumulative) abnormal returns are mainly positive, while findings on abnormal transaction volumes are fairly heterogeneous. Our empirical results are not supported by any of the prevailing theoretical explanations of market reactions to index changes, but, as an important result, all findings depend crucially on the chosen benchmark model.The authors are grateful to two anonymous referees for insightful comments and suggestions and for helpful discussions with Stephan Schmidt-Tank. They would like to thank Fabian Zettler for his assistance in collecting the data. 相似文献

Industry convergence, defined as a 'blurring' of boundaries between industries, induced by converging value propositions, technologies and markets, appears to be a pervasive phenomenon leading to the emergence of inter-industry segments. A current example of convergence can be witnessed in the nutraceuticals and functional foods sector, emerging at the boundary between the food and pharmaceutical industries. Not only technologies blur, but there is also a convergence of demand structures: consumers try to satisfy different needs in one transaction. In this context, this paper explores how actors from different industry-specific resource backgrounds can engage in an innovative activity requiring new technological and marketing competences. Given that absorptive capacity is limited by existing competences, this paper asks how organizations with different R&D competences are able to seize opportunities for innovation emerging from convergence. Empirical findings based on primary data collected from 54 R&D projects of a nutraceutical cluster show that there are different approaches of front end decision making: while some firms follow existing processes for front end decision making, others leave existing paths and need partners to fill in gaps already identified at the front end of innovation. 相似文献

In this paper we empirically test the role of firm-specific financial characteristics as drivers of international investment and production. We hypothesize that financial strength generates advantages that can be exploited through cross-border investment activity. The hypothesis is tested in a series of binary-response models, using a sample of 1379 European non-financial firms’ international acquisitions. Controlling for traditional firm- and target-country-specific foreign direct investment (FDI) determinants, we find strong evidence that financial factors play a significant role in explaining cross-border investment. We conclude that without explicit consideration of the financial dimension, firms’ FDI decisions cannot be properly understood. 相似文献

In recent years the Turkish insurance market has exerted a strong appeal, especially for insurers seated in the EU, in view of its exponential growth rates and its dormant growth potential. EU insurers are, however, subject to more stringent insurance supervisory requirements when entering this insurance market, external to the EU, than when expending into other European insurance markets. 相似文献

This study examines whether foreign institutional investment influences firms’ dividend policies. Using data from all domestically listed nonfinancial firms in China during the period of 2003–2013, we find that foreign shareholding influences dividend decisions and vice versa.Furthermore, changes in dividend payments over time positively affect subsequent changes in foreign shareholding, but the opposite is not true. Our study indicates that foreign institutional investors do not change firms’ future dividend payments once they have made their investment choices in China. Moreover, they self-select into Chinese firms that pay high dividends. Our evidence suggests that in an institutional setting where foreign investors have tightly restricted access to local securities markets and a relatively high risk of expropriation by controlling shareholders exists, firms can use dividends to signal good investment opportunities to foreign investors. 相似文献

Information & communication technology and true real GDP: economic analysis and findings for selected countries 总被引:1,自引:1,他引:0
The expansion of information & communication technology (ICT) is continuing in OECD countries and the world economy – partly due to the ongoing fall of relative ICT prices. The continuing absolute fall of ICT prices and ICT capital prices, respectively, is not adequately considered in the standard analysis of ICT. In the study presented here the ICT investment-GDP ratio is calculated in real terms and it is shown that this ratio is higher (order of magnitude is about 2 percentage points) than the nominal investment-GDP ratio which is misleading the ICT sector, policy makers and society at large. Moreover, we take an innovative look at the digital time budget of private households in selected OECD countries. Assuming that 10 % represents the relevant share of the time budget the digital value-added of private households stands for an unrecorded digital value-added of 2–5 % of gross domestic product; with a share of 20 % of the household’s internet time budget devoted to value-added the hidden internet value-added in the US would be in the range of 4.7–10.4 %. Hence the overall understimation of the ICT sector’s contribution to GDP is considerable and therefore changes in official statistical analysis and the System of National Accounts are required. 相似文献

Responsible supply chain management (RSCM) can help protect a firm's corporate reputation by shielding it from negative media attention and consumer boycotts. RSCM can also enhance a firm's corporate reputation, which allows firms to secure business contracts and penetrate new market segments successfully. This study empirically examines: (i) the extent to which responsible supply chain management practices is driven by a desire to protect corporate reputation; and (ii) whether responsible supply chain management can enhance corporate reputation and thereby generate competitive advantage to the firm. We draw on primary and secondary datasets across seven firms, spanning the publishing, technology, beverage, tobacco, finance and home improvement sectors. We find compelling evidence to suggest that firms often engage in RSCM due to a desire to protect corporate reputation. Similarly, we find empirical evidence to suggest that responsible supply chain practices can enhance reputation and thereby create competitive benefits, although this link is not as profound as the relationship between RSCM and reputation protection and there are significant variations across industries. These findings have significant implications for marketing theory and, in particular, industrial marketers, who are increasingly expected to implement responsible supply chain practices. 相似文献

Due to the increasing importance of producing and consuming energy more sustainably, Energy Informatics (EI) has evolved into a thriving research area within the CS/IS community. The article attempts to characterize this young and dynamic field of research by describing current EI research topics and methods and provides an outlook of how the field might evolve in the future. It is shown that two general research questions have received the most attention so far and are likely to dominate the EI research agenda in the coming years: How to leverage information and communication technology (ICT) to (1) improve energy efficiency, and (2) to integrate decentralized renewable energy sources into the power grid. Selected EI streams are reviewed, highlighting how the respective research questions are broken down into specific research projects and how EI researchers have made contributions based on their individual academic background. 相似文献

Multifunctionality of agriculture: an inquiry into the complementarity between landscape preservation and food security 总被引:2,自引:0,他引:2
Brunstad Rolf Jens; Gaasland Ivar; Vardal Erling 《European Review of Agricultural Economics》2005,32(4):469-488
Without support, the levels of agricultural public goods suchas food security and landscape preservation would fall shortof demand in high-cost countries. However, as demonstrated byNorway as a case study, the current level of support is disproportionatefrom a public goods perspective, and the policy instrumentsare badly targeted at the public goods in question. Becauseagricultural land is a major component of both food securityand landscape preservation, giving rise to a high degree ofcost complementarity between the public goods, it would be moreefficient to support land-extensive production techniques thanproduction per se. 相似文献
