This study examines the influence of day-of-the-week patterns in security returns on long-run IPO underperformance. Comparisons are made between the IPOs in Ritter's [20] database, and a constructed set of matching firms based on SIC code and size, using NYSE, AMEX, and NASDAQ securities. It is found that virtually all of the IPO underperformance occurs on Mondays and Tuesdays and that the degree of underperformance significantly differs from other days. Thus, a common explanation may exist for the general day-of-the-week pattern in security returns and IPO long-run underperformance.  相似文献

This report looks at evaluation studies of a number of cooperative academic-industrfy research programmes in Europe, and suggests that indirect economic benefits should be taken into account as well as motives and goals of participating firms.  相似文献

A conceptual framework of anonymity in Group Support Systems   总被引:2,自引:2,他引:0  
As the development and use of automated systems for collaborative work grows, the need for a better understanding of these systems becomes more important. Our focus is on one type of system, a Group Support System (GSS) and, in particular, on one important aspect of a GSS—anonymity. A conceptual framework for the study of anonymity in a GSS is presented, which describes the general classes of variables and their relationships. These variables include the factors that influence anonymity in a GSS, types of anonymity, and the effects of anonymity on a message sender, receiver, group process, and outcome. Each of these variables is discussed with working propositions presented for important group process and outcome measures. The objectives of this article are to highlight the importance and complexity of anonymity, to act as a guide for empirical investigations of anonymity, and to influence future GSS development and use.  相似文献

Our paper provides a brief review and summary of issues and advances in the use of latent structure and other finite mixture models in the analysis of choice data. Focus is directed to three primary areas: (1) estimation and computational issues, (2) specification and interpretation issues, and (3) future research issues. We comment on what latent structure models have promised, what has been, to date, delivered, and what we should look forward to in the future.  相似文献

This paper explores the relationship between organizational context and the interpretation of strategic issues by examining the hypothesis that CEOs' interpretations of foreign investment in the USA are influenced by the organizational context in which they are embedded. Three aspects of organizational context - the global business experience of the firm; the firm's level of organizational inertia (as represented by firm age and size); and the resources available for responding - are examined as predictors of CEOs' perceptions of foreign investment as a threat or an opportunity. Analysis of data from 320 organizations, controlled by industry, shows that global business experience, firm size, and perceived capability are significant predictors of the perception of threat and opportunity. the discussion addresses the implications of these findings for future research on issue interpretation and organizational context.  相似文献

In this paper we offer a method for deciding how to aggregate a set of elementary industries. The method is then applied to the problem of estimating a wage equation that allows for industry-specific effects. Our method explicitly formalizes the trade-off between goodness-of-fit and parsimony implicit in an aggregation problem. By varying the parameter of the assumed loss function, one obtains a whole sequence of aggregation levels. Further, the resulting sequence is consistent; that is, groupings formed at one level of aggregation will never be undone when one aggregates further.  相似文献

Recent studies suggest the apparent delay in the stock-price response to earnings announcements (i.e., post-earnings announcement drift) is caused by investors who underestimate the autocorrelation of seasonally-differenced earnings (persistence). I present results that suggest: (1) a firm's future persistence is predictable on the basis of its past persistence; (2) the immediate stock-price response to earnings is positively related to historical persistence; (3) post-earnings-announcement drift is independent of historical persistence; and (4) consistent with (2) and (3), the difference between a firm's current observed persistence and that implied in stock prices is independent of its historical persistence. These results extend prior research by demonstrating that investors are aware not only that seasonally-differenced earnings are autocorrelated, but that investors recognize firm-specific differences in the magnitude of the autocorrelation.  相似文献

Hybrid governance forms that seek to meld the virtues of both market control and traditional hierarchical control are alluring. Comparatively little research, outside of the M-form literature, has examined internal hybrids - hierarchical forms infused with elements of market control. This paper contends that common change initiatives, such as TQM, re-engineering, autonomous work teams, and group-based rewards, are appropriately viewed as attempts to craft internal hybrids by selectively infusing elements of market control within hierarchy. However, these change initiatives are often implemented in isolation and, as a consequence, violate patterns of complementarity that sustain traditional hierarchy or support the stable infusion of market control.The paper argues that these violations of complementarity often spiral hierarchies toward fundamental transformation. The clear trajectory of these transformations is to quite radically disaggregated organizations structured around teams. The paper presents both theory and evidence supporting the existence of complementarities among these common change initiatives.  相似文献

The dominant form of equity pay in the U.S. will change dramatically when accounting rules are changed (most likely in 2005) to require companies to charge the cost of their stock option plans on their income statements. Many companies are already switching from stock options to other forms of equity pay, especially restricted stock. The most notable switcher was Microsoft, the world's largest user of stock option pay. In July 2003, partnering with J.P. Morgan, Microsoft created a onetime transferable stock option (TSO) program that allowed holders of underwater Microsoft options to sell their options to J.P. Morgan in return for restricted shares.
But the most important consequence of this transaction may not be a widespread shift by corporate America to restricted shares, but rather the creation of a more costeffective kind of stock option. By clearing the potentially messy hurdles involving taxes, accounting, SEC rules, and "transaction mechanics," Microsoft has opened the door for TSOs to be considered as an ongoing equitypay instrument, perhaps replacing standard stock options (which are not transferable). TSOs share the key advantages of restricted stock in terms of providing robust retention and ownership incentives and higher valuecost efficiency, while maintaining the key "leverage" advantage of options. In so doing, they create significant upside (and downside) while largely avoiding the "pay for pulse" problem of restricted stock. They also introduce the discipline of competitive pricing by third-party bidders. The bid prices of investment banks create nearly all of the information required for accurate estimates of option cost, which should foster greater board accountability and improved corporate governance.  相似文献
