We examine how initial public offering (IPO) valuation has changed over time by focusing on three time periods: 1986-1990, January 1997 to March 2000 (designated as the boom period), and April 2000 to December 2001 (designated as the crash period). Using a sample of 1,655 IPOs, we find that firms with more negative earnings have higher valuations than do firms with less negative earnings and firms with more positive earnings have higher valuations than firms with less positive earnings. Our results suggest that negative earnings are a proxy for growth opportunities for Internet firms and that such growth options are a significant component of IPO firm value.  相似文献

During the past decade, a number of interactive technologies, including the Internet, have fundamentally transformed how retailers compete in the marketplace. In a similar vein, emerging interactive technologies can be expected to significantly alter the retailing landscape through their impact on retailing strategy and operations. Furthermore, it is conceivable that certain emerging interactive technologies will be perceived by some retailers as enablers (tools to more effectively compete in the marketplace) and by other retailers as disruptors of the present ways of doing business. Interactive technologies can either be generic, a technology that is readily available from an information technology (IT) vendor and is widely adopted by retailers, or proprietary. An interactive technology that is proprietary can enable a firm to generate economic rents from the innovation for an extended duration of time. Investing in a generic interactive technology, however, may be perceived as a cost of doing business for a retailer, and not a potential source of sustainable competitive advantage. However, a retailer's complementary resource endowments may enable the retailer to more effectively leverage a generic technology relative to its competitors and thereby achieve a sustainable competitive advantage. In this paper, we review the related literature, develop a process model delineating the mechanisms by which an interactive technology can affect and necessitate changes in retailers' strategies and identify directions for future research.  相似文献

Several theoretical approaches have been put forth to predict and explain the effects of teleconferencing technologies. One approach is to examine the functions of nonverbal signals and to make predictions based on the fact that different teleconferencing technologies allow nonverbal communication to different extents. One of the functions of nonverbal signals is to allow the listener to provide feedback to the speaker in a communication. Prior research has shown that such feedback enhances listener comprehension. In this study, it was hypothesized that different teleconferencing technologies would allow different levels of feedback based on their ability to accommodate nonverbal signals, and this in turn would affect comprehension. An experimental study was conducted to compare comprehension, feedback, and satisfaction in telephone and computer conferencing. The study confirmed that comprehension and speaker satisfaction are related to feedback, but failed to show a relationship between listener satisfaction and feedback. No difference in comprehension, listener, or speaker satisfaction was observed across teleconferencing technologies. Role-related differences were observed between the speaker and the listener. It is suggested that the effects of teleconferencing technologies can be mapped systematically by examining each of the functions of nonverbal signals, one at a time.  相似文献

The member countries of the World Health Organization have endorsed its Global Strategy on Diet, Physical Activity, and Health. We assess the potential consumption impacts of these norms in the United States, France, and the United Kingdom using a mathematical programming approach. We find that adherence would involve large reductions in the consumption of fats and oils accompanying large rises in the consumption of fruits, vegetables, and cereal. Further, in the United Kingdom and the United States, but not France, sugar intakes would have to shrink considerably. Focusing on sub-populations within each country, we find that the least educated, not necessarily the poorest, would have to bear the highest burden of adjustment.  相似文献

The present study examined how ethical beliefs and external factors affecting ethical beliefs are related to age and gender of business professionals. The results indicated that business professionals in the younger age group exhibited a lower standard of ethical beliefs. In the younger age groups, the females demonstrated a higher level of ethical beliefs, while in the older age group, the results suggested that the males had a slightly higher level of ethical beliefs. With regards to the influence of external factors on ethical beliefs, the results yielded a significant interaction between age and gender. The younger age groups, males in particular, were more susceptible to external factors. People at home had the most influence on beliefs about ethics, while the individual's supervisor had the least impact. The results were discussed in terms of theories of moral development.  相似文献

In assessing the usefulness of the analysts’ stock picking advice, the extant literature has largely focused on the profitability of either their stock recommendations or target prices in isolation. In this paper, we examine the profitability of investment strategies that exploit the information analysts convey through revisions in both their stock recommendations and target prices. We find that these strategies significantly outperform the comparable strategies that make use of only one analyst output.  相似文献

The paper offers a possible explanation for the discrepancy between the observed increase in the number of diversified firms in the U.S. and the evidence from finance studies which at best offers only weak support for value creation in diversifying acquisitions. It is argued that the acquisition could be the culmination of a series of related strategic moves by the acquiring firm to enter a new industry, and therefore a significant fraction of the gains from synergy could have been anticipated by the capital market well ahead of the acquisition. Results from an event study of the stock market's reactions to the antecedents of the recent acquisition of Rolm Inc. by IBM lend support to this argument.  相似文献

This paper starts with a survey of the received theories of vertical integration. We then extend these theories by arguing that while uncertainty in general will make integration more effective, a particular type of uncertainty, the possibility of technological obsolescence, works the other way. After making this point at a conceptual level, we build a model to study how the frequency of technological change interacts with the intensity of competition to influence the optimal level of integration. The predictions of the model are then tested and very strongly supported by data from 93 industries.  相似文献

High tech firms can mitigate potential risks by diversifying their product–market portfolios. A key research question is how such diversification influences firm survival. A firm exits the market in two ways, specifically, dissolution and acquisition. Here, we model how the diversity of a new firm's product–market portfolio influences the times to both types of exits. Specifically, we allow for interaction effects of the competitive intensity of a firm's environment and the diversity of a firm's product–market portfolio with its patents and trademarks. Using a competing risk hazard model, we estimate the effects of various covariates on the time to exit for 1435 US high tech firms.We observed that a more diverse product–market portfolio, in conjunction with a larger number of patents, hastens the time to a firm's exit by dissolution (9% decrease in survival duration), while in conjunction with a larger number of trademarks, portfolio diversity delays the time to exit by dissolution (12% increase). A more competitive firm environment results in a greater effect on the portfolio's diversity in delaying its exit by dissolution (7% increase). On the other hand, a diverse product–market portfolio, combined with either a larger number of patents or trademarks, hastens the firm's exit by acquisition (19% and 11% decrease respectively).  相似文献
