In this paper, using daily data for six major international stock market indexes and a modified EGARCH specification, the links between stock market returns, volatility and trading volume are investigated in a new nonlinear conditional variance framework with multiple regimes and volume effects. Volatility forecast comparisons, using the Harvey-Newbold test for multiple forecasts encompassing, seem to demonstrate that the MSV-EGARCH complex threshold structure is able to correctly fit GARCH-type dynamics of the series under study and dominates competing standard asymmetric models in several of the considered stock indexes.

There is a growing interest in understanding consumer ethical actions in relation to their dealings with firms. This paper examines whether there are differences between Northern and Southern European Union (EU) consumers' perceptions of ethical consumer behaviour using Muncy and Vitell's (1992) Consumer Ethics Scale (CES). The study samples 962 university students across four Northern EU countries (Germany, Denmark, Scotland, The Netherlands) and four Southern EU countries (Portugal, Spain, Italy, Greece). Some differences are identified between the two samples, which might question the ability of organisations to consider the EU as one homogeneous market.  相似文献

While financial globalization does not lack theoretical economic merit, the more far-reaching practical consequences of this phenomenon are often not fully appreciated from the vantage point of North America or the European Union. In particular, globalization can make it more difficult for emerging economies to achieve macroeconomic stabilization. This is especially true if the countries in question have chosen the vehicle of pegged exchange rates as an important element of domestic anti-inflation policy. The chief macroeconomic difficulties for emerging economies in a world of volatile capital flows can include a loss of monetary control, a real appreciation of the domestic currency, and a worsening of economic fundamentals leading to damaging currency crises. This paper concentrates on the recent experience of Brazil as illustrative of the abject plight faced by many developing countries attempting to secure economic stabilization against the background of the present globalized international economy.This paper has benefitted from discussion with participants of the Forty-Sixth International Atlantic Economic Conference, Boston, MA, October 8–11, 1998.  相似文献

This study examines the relationship between student perceptions of different types of educator power and different modes of student complaining behaviour in the case of university education. A large sample of marketing students in the business school responded to the study from a state university in Northeastern United States. Factor analysis and canonical correlation analysis are used to explore the relationships between five bases of power perceptions (referent, expert, reward, legitimate, and punishment) and four modes of complaining behaviour (voice, negative word of mouth, third party, and exit). The results indicate that students engage in different modes of complaining as they perceive different types of educator power. The predominant complaining mode is found to be voice under referent or expert power, third party under legitimate power, and exit under reward or punishment power. Our findings offer important implications for student satisfaction, retention, and completion rates in higher education.  相似文献

Supervisory advice is generally given to tax professionals in public accounting firms before they commence tax planning tasks. The objectives of giving advice are to achieve effectiveness and efficiency in tax planning, as well as for training tax professionals. An experiment with 54 tax professionals, from accounting firms across Canada, was conducted to determine the effects of supervisory advice on effectiveness and efficiency in performing tax planning tasks of different complexity. Advice results in lower effectiveness in lower‐complexity tasks, as evidenced by more technically inadequate tax plans, signs of confusion and overdetermined solutions (i.e., unnecessary information in the tax plans). In higher‐complexity cases, the results suggest a limited improvement in effectiveness, as evidenced by more technically adequate plans, but at a cost of limiting insightful judgment. On the other hand, advice results in limited gains in efficiency for both the lower and higher‐complexity tasks. This study extends the advice and tax literatures by investigating the role of advice in the performance of tax planning tasks of different complexity, which has not been examined in other research. This study also contributes to tax practice, as public accounting firms should consider the limited gains in efficiency with the decrease in effectiveness for lower‐complexity tasks and the potential to limit insightful judgment for higher complexity tasks. The results of this study suggest that firms face trade‐offs in achieving efficiency, effectiveness and the training objective.  相似文献

The importance of communication for the successful development of new projects, particularly within the R&D laboratory setting, has been well documented. Yet researchers have seldom examined the relationship between patterns of communication and cross-functional cooperation in the development and management of new programs. In this article Mary Beth and Jeffrey Pinto report on the results of a research study that assessed the relationship of two aspects of project team communication (formal versus informal modes and reason for communication) with the level of cross-functional cooperation actually achieved within a hospital project team charged with developing a new program. A total of 262 team members were surveyed from 72 hospital project teams. The results demonstrated that high cooperation teams differed from low cooperation teams both in terms of their increased use of informal methods for communication as well as their reasons for communicating. Finally, cross-functional cooperation was found to be a strong predictor of certain project outcomes.  相似文献

The effect of time-compressed persuasive communications on listener attitudes was investigated. Previous research has indicated that faster speech rates enhance the perception of a message with no loss in comprehension. However, many of these studies suffer from methodological problems that make their conclusions tentative. The present study is an attempt to clarify the effects of time compression on commercial messages. Eighty subjects listened to one of two commercial messages at one of four speeds: 150, 175, 200, or 225 words per minute (WPM). Subjects later rated the message on several dependent measures using nine attitude rating scales and one behavioral intention measure. Results show support for the moderate speeds of 175 and 200 WPM being the preferred rate of speed on most of the dependent measures. The results suggest that many of the beneficial effects of faster speech rates previously shown may be artifacts of methodological controls.  相似文献

This paper presents estimators of distributional impacts of interventions when selection to the program is based on observable characteristics. Distributional impacts are calculated as differences in inequality measures of the marginal distributions of potential outcomes of receiving and not receiving the treatment. The estimation procedure involves a first non‐parametric estimation of the propensity score. In the second step weighted versions of inequality measures are computed using weights based on the estimated propensity score. Consistency, semi‐parametric efficiency and validity of inference based on the percentile bootstrap are shown for the estimators. Results from Monte Carlo exercises show its good performance in small samples. Copyright © 2015 John Wiley & Sons, Ltd.  相似文献
