The patterns of daily returns in over-the-counter (OTC) stocks are examined to determine if a holiday effect exists in the OTC market. For the sample period of 1973–1989, test results provide evidence of unusually high returns on pre-holiday trading days and unusually low returns on post-holiday trading days in the OTC market. Additional analyses indicate that other documented calendar anomalies do not cause the pre-holiday effect, but the day-of-the-week effect apparently drives the post-holiday effect.  相似文献

Agriculture's importance in the process of economic growth highlights the role of sustained advances in farm production practices by improving the quantity and quality of farm products. In this context, investment in improved agricultural technology continues to be an important avenue of assistance to the developing countries. However, the increased resource pressures facing both aid donors and recipients have emphasised the need for the prior assessment of the potential benefits of aid projects to assist effective aid planning and management. Here, the main requirements are to establish viable project goals for translation into effective programmes, to predict the likely project impacts, and to evaluate the potential benefits and costs of adopting the project's outcomes. An ex ante assessment of assistance in controlling a major livestock disease in Indonesia's eastern islands is described in this paper. The annual net benefits from controlling this disease ranged between $A0.45 and $A2.5 million according to the mortality rate reduction achieved. The benefits were shared between beef producers and consumers according to the market elasticity conditions assumed.  相似文献

Several studies estimate the demand for watching English professional football (soccer) as highly inelastic, a puzzling result given that clubs appear to possess a degree of monopoly power. We discuss weaknesses in earlier studies and offer an alternative method of assessing elasticity based on travel costs of spectators living different distances from the grounds. We find that elasticity varies across the 20 senior clubs for which data were available but in almost every case demand is more elastic than reported in the existing literature and pricing policy appears therefore to be more orientated towards profit maximisation than previously thought.  相似文献

The authors show that an increase in international borrowing increases specialization and unemployment in a small open economy that is subject to terms‐of‐trade risks. The economy has a production advantage in the export sector. However, the size of the export sector is limited by the available funds. To insure workers against income fluctuations arising from terms‐of‐trade risks, firms in the export sector offer workers a stable wage rate with the possibility of unemployment. An increase in international borrowing increases specialization in the export sector, which leads to higher unemployment when the terms‐of‐trade shock is bad. A state‐contingent price subsidy can reduce unemployment without inefficiently reducing specialization. The results are robust to the introduction of risk‐averse firms.  相似文献

This article is written in the context of current British interest in management training and development, in which an emphasis on competency is viewed critically, as technically oriented, with little attention paid to ethics and moral values. It is suggested that a concern for ethics in management development can be expressed in terms of four requisite management attributes or qualities: theoretical knowledge and understanding; affective qualities; personal and interpersonal skills; and self-knowledge. Following Kohlberg's work on moral development, the cultivation of these attributes is viewed as a life-span process involving three broadly defined forms of management development practice, each appropriate to different circumstances and stages in a learner's career. It is concluded that the conventional teaching of theory, learning from experience and counselling/mentoring, are equally important in the contribution which management development can make to the resolution of ethical dilemmas in business practice.Patrick Maclagan is a lecturer in organisational behaviour and managerial ethics at the School of Management, University of Hull, U.K., where he is also on the Steering Committee of the Social Values Research Centre, His current research concerns the relationship between management development and ethics in organisations.  相似文献

We provide a convenient econometric framework for the analysis of nonlinear dependence in financial applications. We introduce models with constrained nonparametric dependence, which specify the conditional distribution or the copula in terms of a one-dimensional functional parameter. Our approach is intermediate between standard parametric specifications (which are in general too restrictive) and the fully unrestricted approach (which suffers from the curse of dimensionality). We introduce a nonparametric estimator defined by minimizing a chi-square distance between the constrained densities in the family and an unconstrained kernel estimator of the density. We derive the nonparametric efficiency bound for linear forms and show that the minimum chi-square estimator is nonparametrically efficient for linear forms.  相似文献

This article provides a series of reflections on the practice of carrying out processual research on organisational change. At a broad level, some of the main tasks associated with conducting company case studies are described and the benefits of this approach for dealing with complex change data are outlined. At a more specific level, the article addresses three main areas tied to the actual “doing” of processual research. First, the notion of tacit knowledge and “getting your hands dirty” by engaging in ongoing in-depth fieldwork. Second, the design and implementation of a longitudinal case study research programme. Third, the advantages and concerns of combining a range of different data collecting techniques in carrying out processual studies. Overall, the main intention is to provide some useful reflections and practical insights, as well as providing something of the flavour of carrying out this type of research.  相似文献
