This paper examines the effect of product market uncertainty and government research and development (R&D) subsidies on firm-level R&D investment. Using a sample of German manufacturing firms, we find that product market uncertainty reduces R&D investment and government R&D subsidies increase R&D investment. Moreover, our results indicate that R&D subsidies mitigate the effect of product market uncertainty on R&D investment. These findings suggest that public policies aimed at increasing business R&D investment can achieve this objective by reducing the degree of uncertainty in the product market.   相似文献

Post-IPO Operating Performance, Venture Capital and the Bubble Years   总被引:1,自引:0,他引:1  
Abstract:  We analyse the post-issue operating performance of 316 venture-backed and 274 non-venture UK IPOs 1985–2003. The finding of a statistically significant five-year, operational decline exhibited over the full sample period is not robust. Rather it is driven by the dramatic underperformance during the 1998–2000 bubble years while IPOs perform normally in the remaining years. Cross-section regression results indicate support for venture capital certification in the non-bubble years but a significantly negative relationship between operating performance and venture capitalist board representation during the bubble years. The bubble year underperformance is explained by market timing and by low quality companies taking advantage of investor sentiment.  相似文献

Prior governmental research implies a positive relation between auditor specialization and audit quality, but the effect of specialization on audit fees is mixed. However, no single governmental study investigates the effect of auditor specialization on both audit quality and audit fees. Also, prior studies focus on either large- or small audit firms and often employ indirect proxies for audit quality. We study the effects of auditor specialization on perceived audit quality and audit fees. Our data represent both Big 5 and smaller audit firms and include three market-based measures of specialization. We survey 241 Florida local government finance directors and find that specialization is positively associated with perceived audit quality but not with audit fees. We also find that Big 5 auditors, often used as a proxy for higher audit quality in prior research, are not uniformly associated with increased perceived audit quality but consistently charge higher audit fees. Our results confirm a relation between measures of audit firm specialization and audit quality and raise questions regarding audit firm size and audit quality in the municipal sector. Our findings suggest that engaging specialized auditors may be good policy for many local governments.  相似文献

Using only the definition of returns, together with a transversality assumption, we demonstrate that given a dividend process, any one of three variables—expected return, return volatility, and the price–dividend ratio—completely determines the other two. By parameterizing only one of these processes, common empirical specifications place strong, and sometimes counter-factual, restrictions on the dynamics of the other variables. Our findings lend insight into the nature of the risk–return relation and the predictability of stock returns.  相似文献

abstract From a narrative perspective, organizations' identities are discursive (linguistic) constructs constituted by the multiple identity‐relevant narratives that their participants author about them, and which feature, for example, in documents, conversations and electronic media. By defining collective identities as the totality
of such narratives I draw attention to their complex, and often fragmented and heterogeneous nature. My approach contrasts with much of the theorizing in this field which has tended to homogenize collective identities by emphasizing what is common
or shared, failed to capture the interplay between different communities within organizations, and produced bland, undifferentiated empirical research. In particular, the theoretical framework that I outline focuses attention on the importance of reflexivity, voice, plurivocity, temporality, and fictionality to an understanding of collective identities as locales for competing hegemonic claims. In combination, these notions form a unique conceptual model for theorizing and researching collective identities. This said, a narrative approach also has its limitations, and is proposed as an additional, not exclusive, interpretive lens.  相似文献

The method used expert opinions (collected through interviews), scenario generation, and a simple econometric model. Some methodological innovations are reported; eg aids to assist experts in thinking ahead, and in how scenarios are generated and aggregated.  相似文献

This paper explores the use of scenario planning and the design of a knowledge‐based system in strategic decision making, in the context of the European airline industry. Several innovative strategies were derived, as well as other key recommendations based on sound strategic reasoning, and participants testified to the effectiveness of the approach in stretching their thinking. The requirement to draft strategies as expert system rules, with reasons, was useful in clarifying thinking and achieving group consensus. This methodology, therefore, aids effectiveness of the scenario planning process itself, while providing a dynamic, accessible means of storing the resulting strategic thinking.

This paper reassesses the domain of the business ethics curriculum and, drawing on recent shifts in the business environment, maps out some suggestions for extending the core ground of the discipline. It starts by assessing the key elements of the dominant English- language business ethics textbooks and identifying the domain as reflected by those publications as where the law ends and beyond the legal minimum. Based on this, the paper identifies potential gaps and new areas for the discipline by drawing on four main aspects. First, it argues that the domain of business ethics requires extensions dependent on the particular geographic region where the subject is taught. A second factor for broadening the scope is the impact of recent scandals, which arguably direct the focus of ethical inquiry towards the nature of the business systems in which individuals and corporations operate. Third, the impact of globalization and its result on growing corporate involvement in regulatory processes is discussed. Fourth and finally, business ethics reaches beyond the traditional constituencies of economic stakeholders as new actors from civil society enter the stage of ethical decision making in business. We conclude by suggesting that a reconsideration of the domain of business ethics, especially in Europe, is timely, but that to do so represents a major challenge to business ethics educators.  相似文献
