Odd lot trading and earnings announcements

This study investigates odd lot trading, both trades and orders, around quarterly earnings announcements to determine whether odd lot traders are informed regarding the information contained in earnings announcements. We find pre-announcement odd lot order imbalances are not positively correlated with post-announcement returns and odd lot traders do not earn excess returns. Portfolios long stocks highly bought by odd lot traders in the pre-announcement period and short stocks highly sold by odd lot traders do not outperform the market. We conclude that odd lot traders are not in possession of earnings announcement information prior to its release to the public.     

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     

Secondary markets with changing preferences

If consumer valuations change over time, then secondary‐market frictions may raise monopoly profits and cause durability to be distorted away from the cost‐minimizing level. A monopolist who favors such frictions overinvests in durability, but planned obsolescence instead may be preferred when market frictions exist but a monopolist wishes they did not. Evidence from the book market is presented.     

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.     

Rent Paying Ability and Racial Settlement Patterns

A bstract . Based on the belief that the major remaining hurdle to integration is economic , the proposition has frequently been advanced that if minority households could afford decent housing outside their current communities , many would move from their ghettoes into society at large. Evidence from two housing allowance demonstration projects and the recently completed Experimental Housing Allowance Program raises doubts as to the validity of this contention. While recipients of housing allowances frequently moved to better neighborhoods , only rarely were they able to break free of traditional settlement patterns . Findings suggest that while it may be necessary to increase the rent paying abilities of low-income minority households as a precondition of integration, that segregation is not likely to be eliminated until the social, psychological, and remaining legal issues associated with it are addressed as well.     

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.
