We examine the impact of initial public offerings (IPOs) on rival firms and find that the valuation effects are insignificant. This insignificant reaction can be explained by offsetting information and competitive effects. Significant positive information effects are associated with IPOs in regulated industries and the first IPO in an industry following a period of dormancy. Significant negative competitive effects are associated with larger IPOs in competitive industries, those in relatively risky industries, those in high‐performing industries, and those in the technology sector. IPO firms that use the proceeds for debt repayment appear to represent a more significant competitive threat to rival firms relative to IPO firms that use their proceeds for other purposes. 相似文献

Transition patterns from school to work differ considerably across OECD countries. Some countries exhibit high youth unemployment rates, which can be considered an indicator of the difficulty facing young people trying to integrate into the labour market. At the same time, education is a time‐consuming process, and enrolment and dropout decisions depend on expected duration of studies as well as on job prospects with and without completed degrees. One way to model entry into the labour market is by means of job‐search models, where the job arrival hazard is a key parameter in capturing the ease or difficulty in finding a job. Standard models of job search and education assume that skills can be upgraded instantaneously (and mostly in the form of on‐the‐job training) at a fixed cost. This paper models education as a time‐consuming process, a concept which we call time‐to‐educate, during which an individual faces the trade‐off between continuing education and taking up a job. 相似文献

An Erratum for this article has been published in Journal of Applied Econometrics 18(2) 2003, 249 Previous empirical work on corporate growth rates using cross‐section or short‐panel econometric techniques suggests that growth rates are random but that some degree of mean reversion exists. This means that size differences between firms are transitory. Another, more natural way to explore the long‐run distribution of firm sizes is to examine data on the growth of particular firms over long periods of time. Using a sample of 147 UK firms observed continually for more than 30 years, our conclusions are that growth rates are highly variable over time and that differences in growth rates between firms do not persist for very long. Further, firms show no tendency to converge to either a common size or to a pattern of stable size differences over time. These results are compared and contrasted with standard approaches that suggest that firms reach and maintain stable positions in a skewed size distribution.

The general design for the real-time electricity market presented in this paper optimizes and prices both real and reactive
power simultaneously in an AC setting, where all assets—generation, load and transmission—are allowed to bid and are financially
settled at the locational price times energy consumed or produced. The result is that transmission lines are compensated for
both capacity and admittance, providing incentives for efficient operation of transmission-related assets such as FACTS devices,
if price-taking behavior is assumed. Losses are incorporated into the design and become an operating cost for transmission.
The market design is shown to be revenue neutral and, under some assumptions, nonconfiscatory.

Practitioners and regulators are concerned that when auditors perceive management's attitude or character as indicative of low fraud risk, they are not sufficiently sensitive to high levels of incentive or opportunity risks in their overall fraud‐risk assessments. In this study, we examine whether a fraud‐triangle decomposition of fraud‐risk assessments (that is, separately assessing attitude, opportunity, and incentive risks prior to assessing overall fraud risk) increases auditors' sensitivity to opportunity and incentive cues when perceptions of management's attitude suggest low fraud risk. In an experiment with 52 practicing audit managers, we find that auditors who decompose fraud‐risk assessments are more sensitive to opportunity and incentive cues when making their overall assessments than auditors who simply make an overall fraud‐risk assessment. However, this increased sensitivity to opportunity and incentive cues appears to happen only when those cues suggest low fraud risk. When opportunity and incentive cues suggest high fraud risk, auditors are equally sensitive to those cues whether they use a decomposition or a holistic approach. We discuss and examine potential explanations for this finding. 相似文献

Many studies examine firm private knowledge, but purport to be generalizable to the totality of firm knowledge, both public and private. This study demonstrates that public and private firm knowledge are empirically separable constructs that have significant and yet different influences on innovative outcomes. The example of product development effectiveness within this study shows that both public and private knowledge are significantly related to product development quality; however, public knowledge is negatively related to quality lapses while private knowledge is positively related to quality lapses.

An Internet presence is a critical early component in the process of building towards a fully operational and unified e‐commerce strategy. E‐commerce has significantly impacted logistics/supply chain strategies and the development and implementation of a website have become key issues for many firms within the transportation industry. This study provides an overview of website content within the motor carrier industry. Content analysis was used to assess the site design, informational content, and the interactive content of 152 motor carrier websites, and to compare the features offered on the Top 100 motor carrier firm websites with those offered on the sites of smaller carrier firms. 相似文献

This paper challenges the common view that mature industries are always ripe for global strategies. Based on data from the European Domestic Appliance industry, this paper shows how changing economic conditions can diminish the value of global strategies. Critical in these shifts were simultaneous rises in demand for variety (that eroded the benefits of scale and continental market share) and decreases in manufacturing scale (that permitted new supply options), which reduced the extent of the strategic market to national dimensions. They added complexity that decreased the profitability of the global players and increased that of national strategies. The fluctuating fortunes of leading firms are shown to have been caused primarily by choices of strategy, not by national factor costs. 相似文献

In this comment we identify the key features of the Frantz and Walker (1997) game theoretic model that drive the non-disclosure equilibrium result in their paper. We argue that, although technically correct, their model fails to capture certain aspects of real-world wage bargaining that will be important in determining optimal disclosure strategies in practice. However, Frantz and Walker's paper illustrates the potential of analytical techniques to contribute to the employee disclosure debate. 相似文献
