Ample evidence suggests that day-of-the-week patterns exist in US and foreign equity returns. We extend the evidence on the day-of-the-week effect in equity returns by examining the return patterns of iShares for 17 countries and Standard and Poor's Depository Receipts (SPDRs) to establish whether previously observed predictabilities in equity returns are reflected in iShares' returns. We utilize a split sample to examine return patterns and develop trading rules using the initial subsample. We then test those trading rules out of sample. Empirical results reveal that iShares exhibit day-of-the-week return patterns that can be exploited by informed traders.  相似文献

The objective of this paper is to expand and update previous New Zealand — based surveys in order to compare and contrast risk management practices of firms in the small, foreign trade-dependent economy of New Zealand to those of firms in the considerably larger, more developed US, UK, and German markets. This survey examines patterns of usage, reasons and objectives for derivatives use, and reporting and control procedures and finds that the practice of hedging with derivative instruments among New Zealand firms appears to be evolving as global markets become more integrated. We find that the percentage of firms involved in hedging, both large and small, has grown since the last New Zealand surveys, and that New Zealand firms have many of the same reasons and objectives for using derivatives as firms in the much larger American and European economies. We also find that the focus on control and reporting derivatives transactions in New Zealand is similar to that of firms in the other countries and appears to have strengthened since previous surveys.  相似文献

A horseshoe is regarded as a lucky, perhaps even romantic, symbol of our industrial heritage. Why is it, then, that much of English literature, from Mandeville's ‘Grumbling Hive’ on, portrays business in a murky light? The paper begins with an analysis of this phenomenon and concludes that it is the institutionalisation and legitimisation of avarice and its consequential effects that gives rise to such a portrayal. A horseshoe has also been used as a convenient means of conceptualising an answer to the questions this conclusion raises: ‘Who should control the corporation and for what ends?’ (Mintzberg 1985) and discussing recent developments in corporate social responsibility. Drawing on research evidence the paper demonstrates how corporations are simultaneously under pressure from society and responding to its concerns. The paper concludes that these current developments can at best ameliorate the situation, and that what is necessary is to rediscover the notion of corporate virtue, instead of putting virtue at the service of vice.  相似文献

This paper presents tests of the screening hypothesis using data on adult males from the 1996 Australian Census of Population and Housing. These tests are based on comparisons of wage and salary earners and the self-employed, and public and private sector workers, as examples of screened and unscreened employments. The first test compares the mean levels of schooling, income and labour market experience in screened and unscreened sectors, while the second examines the returns to schooling and the goodness of fit of the earnings models for both wage and salary earning (separated into public and private sector employees) and self-employed groups. The results are equivocal, but suggest screening could be part of the earnings determination process in the Australian labour market.  相似文献

A small but growing body of literature searches for evidence of non-Keynesian effects of fiscal contractions. That is, some evidence exists that large fiscal contractions stimulate short-run economic activity. This article continues that research effort by systematically examining the effects (if any) of unusual fiscal events—either non-Keynesian results within a Keynesian model or Keynesian results within a neoclassical model—on short-run economic activity. The authors examine this issue within three separate models—a St. Louis equation, a Hall-type consumption equation, and a growth accounting equation. The empirical findings do not provide strong systematic support for the view that unusually large fiscal contractions/expansions reverse the effects of normal fiscal events. Moreover, the authors find only limited evidence that trigger points are empirically important.  相似文献

Local amenities play an important role in determining where we choose to live and our overall quality of life (QOL). In many cases, however, amenities do not have prices and will therefore be underprovided by the market. In this paper, we use individual and county level data for England and Wales to estimate implicit amenity prices and to calculate an index of QOL for each county. Among our findings is a large negative price on air pollution. The range in QOL across counties is estimated to be in excess of 2,000 pounds per year.  相似文献

The evaluation of the impact of changes in reward systems is a common recommendation in the personnel practitioner literature, but little has been written about how and to what extent practitioners themselves evaluate. This article therefore focuses on the activities of HR managers who have introduced new pay systems, not on academic studies of reward system change. Face‐to‐face interviews were conducted in 15 large, unionised organisations in England between 2000 and 2002. The study found that little formal evaluation of changes in pay and grading systems had been carried out and that managers expressed considerable scepticism about the evaluation process. They relied heavily on informal or anecdotal feedback, and appeared to have little psychological incentive to evaluate. The article suggests explanations for this lack of formal evaluation, drawing on the management decision‐making literature, and recommends how changes in reward systems should be evaluated.  相似文献

This study examines the determinants of high school graduation in Australia. It uses two main approaches to estimation. The first of these is a conventional probit model based on a range of family background and demographic variables. This approach is then extended through consideration of a random parameters probit model. The results show that schools matter to the chances of completing high school in Australia. However, the school effects seem to have more to do with the selection of more able students with superior socioeconomic backgrounds than with the independent creation of favourable school or classroom climates.  相似文献

Managing knowledge inventories is the central issue posed by the knowledge‐based view of the firm. Knowledge inventory management involves acquiring, retaining, deploying, idling, and abandoning technologies. Because of future opportunities to switch technologies over time, managing knowledge inventories requires valuing flexibility. Real option theory presents normative conceptual frameworks and pricing formulas for valuing flexibility. These formulas assume managers consider the full time horizon of technologies as well as all available substituting and complementary technologies. This study considers the implications of violations of these assumptions (i.e., temporal and spatial myopia) for managers' technology investment decisions. Specifying decision criteria under alternative forms of myopia reveals possible sources and patterns of technology management decision errors. This study highlights the cognitive sources of path dependencies and organizational rigidities. Copyright © 2002 John Wiley & Sons, Ltd.  相似文献
