I show the ratio of the short‐term moving average to the long‐term moving average (moving average ratio, MAR) has significant predictive power for future returns. The MAR combined with nearness to the 52‐week high explains most of the intermediate‐term momentum profits. This suggests that an anchoring bias, in which investors use moving averages or the 52‐week high as reference points for estimating fundamental values, is the primary source of momentum effects. Momentum caused by the anchoring bias do not disappear in the long‐run even when there are return reversals, confirming that intermediate‐term momentum and long‐term reversals are separate phenomena.  相似文献

This paper evaluates prospective technology areas, development strategies, and various innovation resources in China's pharmaceutical sector through the use of a hierarchical decision model. The results indicate that although domestic SMEs are the major preferred innovation alternative, it is followed closely by foreign MNCs. The sensitivity analysis indicates that the effectiveness of policy decisions are influenced by certain high technology areas. Recombinant therapeutic proteins, recombinant vaccines, and monoclonal antibody technologies are identified as the major areas that will influence the priority of innovation resources. The research crafts a research framework to formulate innovation strategies in dealing with the uncertainties of technology development and policy decisions in the biopharmaceutical industry.  相似文献

Although the direct effects of work–family enrichment on satisfaction are well-documented, previous theoretical predictions and empirical findings of the relationship have been inconsistent. Drawing on social cognitive theory, the current research examined how work–family enrichment contributes to job and family satisfaction by exploring the mediating mechanisms of self-efficacy and work–life balance. This study also empirically validated a new self-efficacy measure using the work–life interface nomological network. A heterogeneous sample of Australian employees (N = 234) from four different organisations responded to two waves of data collection separated by a 12-month interval. Using structural equation modelling, the results of the statistical analysis provided preliminary support for the hypothesised chain mediation model and the newly developed five-item self-efficacy to regulate work and life scale. Specifically, work-to-family enrichment and family-to-work enrichment were positively related to self-efficacy, which in turn had a positive effect on work–life balance. Similarly, work–life balance had a positive impact on job and family satisfaction. Evidence of these relationships over time was demonstrated, thereby emphasising the importance of person–cognitive resources (e.g. self-efficacy) in influencing life outcomes. Validation of the self-efficacy scale also demonstrated robust psychometric properties and criterion validity. Implications of these results were subsequently discussed.  相似文献

Most traditional approaches to capital expenditure analysis have been partially successful in explicitly accounting for risk. A utilitarian model for risk treatment is described in this paper. Specifically, we address two major aspects of the utilitarian approach: (1) the mathematical legitimacy of the underlying utility function with respect to its domain of economic significance and (2) the way “Expectancy-Variance” and “Expectancy-Semivariance” compare as risk/return trade-off criteria. In particular, we have shown how commonly used quadratic utility functions present some theoretical and practical inconveniences from an economic standpoint. Then, a hybrid utility function is introduced as a more legitimate and often more realistic model where semi-variance, rather than variance, is used as a measure of the investment riskiness.  相似文献

The CAPP model (Maloney, 1966; Aaker & Myers, 1987) was used to evaluate the anti-smoking advertising campaign in Hong Kong. The findings indicated that the campaign has different communication effects on smokers and non-smokers. Though more smokers can comprehend the message correctly, a smaller number of them have formed a negative attitude towards smoking as compared to non-smokers. Based on the attitudinal differences of the two groups, implications with respect to advertising appeals can be drawn. This study also suggests that the government's campaign should seek to establish a negative attitude towards smoking by smokers.  相似文献

以焦化汽油作为参比对象,采用静态和动态两种评价方法,对催化裂解装置主分馏塔一级冷后汽油在加氢脱硫过程中的结焦性进行了评价。从静态挂片结焦增重、动态反应前后动态测试管出口油样温差、烯烃减少幅度等方面的情况来看,催化裂解装置主分馏塔一级冷后汽油的结焦倾向小于焦化汽油。  相似文献

Influential or frequently cited business ethics research does not appear in a vacuum; our study reveals its predominant sources and contributors by discipline. By examining citations from articles published in three top business ethics journals (Journal of Business Ethics, Business Ethics Quarterly and Business Ethics: A European Review) over the period 2004–2008, we document that the preponderance of influential business ethics research comes primarily from the management faculty. In addition, management journals and management books are the predominant sources for influential business ethics research. Further, among the management fields, organizational behavior and organizational structure predominate leadership and strategy as the major subject areas for influential business ethics research, suggesting that this influential body of research is focused on a micro rather than on a macro context. These empirical results lend credence to the perception that there is a silo effect in influential business ethics research and suggest that business ethics research in a micro context might have permeated to the teaching of business ethics.  相似文献

We introduce a new class of numerical schemes for discretizing processes driven by Brownian motions. These allow the rapid computation of sensitivities of discontinuous integrals using pathwise methods even when the underlying densities postdiscretization are singular. The two new methods presented in this paper allow Greeks for financial products with trigger features to be computed in the LIBOR market model with similar speed to that obtained by using the adjoint method for continuous pay‐offs. The methods are generic with the main constraint being that the discontinuities at each step must be determined by a one‐dimensional function: the proxy constraint. They are also generic with the sole interaction between the integrand and the scheme being the specification of this constraint.  相似文献

The purpose of this study is to examine the perceptions of Hong Kong (HK) legal practitioners on how the major attributes of knowledge, continuous education, and qualification among directors in HK relate to their board of directors' corporate governance effectiveness. The results revealed that the respondents perceived directors' attributes in HK to be not good enough for discharging their legal obligations to their companies. The results also suggested that a company was more effectively governed if its directors were more qualified for their jobs and more familiar with company law and/or corporate governance.  相似文献

This paper analyses gender wage differentials and the role of occupational segregation in Hong Kong. It is found that the female–male earnings ratio increased substantially from 0.710 in 1981 to 0.839 in 1996. A decomposition which takes into account occupational differences shows that the gender pay gap is mostly within occupations and most of the intra‐occupation wage gap is unexplained. The gender pay differential due to occupational differences is small; in fact, the overall occupational segregation favours females in Hong Kong.  相似文献
