Strength in numbers or guilt by association? Intragroup effects of female chief executive announcements

We predict that the media reports on female CEOs as a coherent group, whereas male CEOs are treated as individuals by the media. We also suggest that the resulting investors' perceptions of group entitativity of female‐led firms may not only influence the succession event–performance relationship at the focal firm, but may also have a significant effect on the value of other female‐led companies. Results of a text analysis and an event study of appointments of female CEOs to Fortune 1000 firms provide support for these predictions. Copyright © 2013 John Wiley & Sons, Ltd.     

ATE行业增效求生存

如今,运营重点集中在减少成本和增强快速响应能力上自从2001年,自动测试设备(ATE)市场增长相当缓慢甚至陷于停滞,然而,ATE制造商Advantest(爱德万)、Agilent(安捷伦)、Credence(科利登)和 Teradyne(泰瑞达)为了争夺市场份     

资本设备销售完成今年预期值

随着全球各地涌现出40多家新代工厂,分别处于在建、添加新设备或者扩大生产规模的状态,加之电子行业目前正由200mm转向300mm晶圆生产,资本设备的定购额目前已经达到许多分析家当初所预计的2006年全年的产量。事实上,国际半导体设备与材料公会(SEMI)在其最新一期网络季报中,对2006年资本设备市场增长的预测比原来翻了一番还多(原始预计增长率为9%,而现在已提升到20%)。明年这一市场的增长很可能不会像最初所预计的那样强劲,但     

Supply Dynamics in the U.S. Hog Industry

A variety of methods and empirical techniques are now available for estimating dynamic economic relationships. Unfortunately, most dynamic modeling procedures rely heavily on the sample data for specification. This is due to a lack of a priori information useful for determining the appropriate lag structure. However, there is frequently a rich source of information that can be used to define lag structures in agricultural supply models. This information is related to the biological and physiological processes characterizing agricultural production. In this paper, a quarterly econometric model of supply response in the U.S. hog industry is specified and estimated. This model incorporates relevant biological features of hog production directly into the specification. The structural integrity of the model is evaluated by examining post-sample predictive ability and mean-path elasticities. The results indicate performance that is consistent with observed behavior in the U.S. hog industry. Nous disposons aujourd'hui de toute une gamme de méthodes et de techniques empiriques pour ?estimation des rapports économiques dynamiques. Malheureusement, la plupart des méthodes de modélisation dynamique dépendent étroitement, pour leurs spécifications, sur des données échantillonnées. Ceci découle ?un manque ?informations a priori utiles pour la détermination de la structure de retard appropriée. Toutefois, on dispose fréquemment ?une riche source ?informations qui peuvent servir à définir les structures de retard dans les modèles de ?offre en agriculture. Cette information est liée aux processus biologiques et physiologiques caractérisant la production agricole. Dans le présent document, nous procédons à la spécification et à ?estimation ?un modèle économétrique trimestriel du comportement de ?offre dans le secteur américain du pore. Ce modèle incorpore directement dans la spécification les caractéristiques biologiques pertinentes de la production porcine. Nous évaluons ?intégrité structurale du modèle en examinant ?aptitude prédictive post-échantillonnage et les valeurs moyennes ?élasticité. Nos résultats laissent conclure à une performance qui vient corroborer le comportement observé dans le secteur américain du porc.     

Homeownership and mixed-asset portfolio allocations

Homeownership represents both a consumption and an investment decision for individuals. Considering the investment benefits of the home, we estimate the total returns and risk associated with the investment in single-family homes. Then, using a mean–variance utility function, we consider the impact of homeownership and mortgage loan financing on the optimal asset allocation decisions of individuals and contrast this with advice that does not include the home as part of the portfolio. While optimal portfolio weights are dependant upon both the degree of risk aversion of the individual investor and the relative importance of the home in the overall net worth picture, we show that, in general, the higher the home-to-net worth ratio, the higher the optimal portfolio allocation to stock. For most investors, including the home in the optimization decision leads to higher allocations to risky stock than suggested by traditional advice that ignores the home.     

In search of E. I. DuPont de Nemours & Company: the perils of archival research

The purpose of this paper is to describe the pitfalls of archival research into the bookkeeping records of a specific firm, E. I. DuPont de Nemours & Co., and how it may lead to misinterpretation and misdirection. Traditionally, the bookkeeping records of an individual or organization have provided a great deal of information to researchers who use the records for many different research projects. Such research is costly, however. The researcher is concerned with the analytical techniques of the historian, or even the detective; the time-consuming, methodical routine of familiarization with the records; and the analysis and interpretation of the significance of the techniques and trends evident in the data base. The sources for this traditional archival research project were many, varied, and often contradictory. For the record books of the DuPont Company, an early 19th century gunpowder manufactory, the process of understanding, interpreting, and validating the record keeping led to a number of misleading, confusing, and time-consuming issues which had to be resolved. These issues may have implications for other accounting historians since the need to search for the 'story' behind a particular research project will in all likelihood be encountered in the course of other research. Researchers must understand that they are able to rely on secondary sources, when they exist, only as long as they remain circumspect when depending on the secondary interpretation of primary sources, and that even the primary sources themselves may lead the researcher astray.
