The relaxation of security laws and regulations in emerging markets in the Middle East and North Africa (MENA) provides abundant opportunities for foreign investors. These markets exhibit high-expected returns and substantial volatility. In this paper, we investigate the lead/lag relationship between the MENA countries and regions. We find no market causality or spillover from one country to another in the North Africa region. Our results for the Levant region reveal that there are linkages between stock markets in this region. The results for the Gulf Cooperation Council (GCC) region show that there is more interaction and linkage in the GCC region than in the North Africa and Levant regions. An unexpected result is that UAE's stock market leads all the markets in this region. Finally, we investigate linkages among the three regions. We find that GCC influences the other two regions.  相似文献

We examine the role of index futures trading in spot market volatility. We use the exponential generalized autoregressive conditional heteroskedasticity (EGARCH) approach to measure volatility, analyze causality and feedback relations between volatilities in the spot and futures markets, and test various hypotheses in the context of a multivariate model that incorporates other macrostate variables. Our empirical results suggest index futures trading may not be blamed for the observed volatility in the spot market. Rather, we find stronger and more consistent support for the alternative posture that volatility in the futures market is an outgrowth of a turbulent cash market. We use the regret (cognitive dissonance) theory to explain our results.  相似文献

The study examines the relative ability of various models to forecast daily stock index futures volatility. The forecasting models that are employed range from naïve models to the relatively complex ARCH-class models. It is found that among linear models of stock index futures volatility, the autoregressive model ranks first using the RMSE and MAPE criteria. We also examine three nonlinear models. These models are GARCH-M, EGARCH, and ESTAR. We find that nonlinear GARCH models dominate linear models utilizing the RMSE and the MAPE error statistics and EGARCH appears to be the best model for forecasting stock index futures price volatility.  相似文献

The role of production technology for sustainable economic growth and resource management in the multispecies renewable resources industries is a neglected issue, particularly in complex tropical ecosystems. Given the still rudimentary understanding of biological interactions among species, even in most temperate ecosystems, the importance of under-standing the technological and economic interactions is heightened for sustainable economic growth and public regulation. This paper evaluates these interactions for the multiproduct gill net fisheries of Peninsular Malaysia. Standard price and quantity controls may have little promise. Gear regulations, a policy of constant escapement, and managing the entire mix of species as a single stock for economic rather than biomass yield appear the most promising management tools given the limited regulatory options.  相似文献

It is recognized that public health intervention targeted toward changing lifestyle behaviors to reduce overweight status is a considerable challenge. It is important that individuals recognize their overweight status as a health risk in order for an effective change in lifestyle behaviors to occur, and growing evidence suggests that actual weight and perception of weight status often do not match, especially among adolescents. In this article, we explore the extent to which exposure to heavier peers and parents affects misperception of their own weight status by adolescents. Using data from a nationally representative sample of adolescents, we estimated instrumental variable models with school‐level fixed effects to account for bidirectionality of peer influence and environmental confounders. Our results indicate that individuals who live in an environment that exposes them to overweight/obese parents and heavier peers tend to misperceive their weight status and think of themselves to be of lower weight than they actually are. Our analysis also revealed differential effects by gender and type of peers.  相似文献

Despite the rapid growth of Internet banking (IB), customers in developing countries still hesitate to adopt this technology and its use in the Middle East remains low. This study aims to identify and examine the factors that predict behavioural intention and adoption of IB in Jordan. Four factors – hedonic motivation, habit, self-efficacy and trust – are proposed in a conceptual model. Data was collected by means of a survey with bank customers in Jordan. Structural equation modelling (SEM) was used to analyse the data. The results strongly supported the conceptual model. Further, hedonic motivation, habit, self-efficacy and trust were all confirmed to have a significant influence on behavioural intention. Trust was found to be strongly predicted by both hedonic motivation and self-efficacy. This study provides both academics and practitioners with an insight into the factors that can be used to encourage customer adoption of IB specifically in a Middle East context.  相似文献

ABSTRACT

Music participation is a way of life for many cultures and is an activity that is often passed on generationally. It can become especially important as a leisure activity for maintenance of self- and national identity for people who have migrated to countries of contrasting cultures, such as Australia. This article describes exploratory, qualitative research into the ways in which participatory music-making within communities from immigrant backgrounds in Brisbane, Australia may influence aspects of participants’ wellbeing. The sample for this research included three broadly-defined cultural groups living in the region: people of Baltic origin; people from Latin American and Caribbean backgrounds; and ‘newly arrived’ immigrants and refugees. Interviews with individuals have been analysed to explore the ways in which this involvement might affect mental, social, and emotional wellbeing. Our qualitative analyses demonstrated that beyond these aspects, factors of subjective wellbeing, both hedonic and eudaimonic, were apparent. This article aims to provoke discussions on the divergent ways in which immigrant communities utilise music-making practices to foster different types of wellbeing and the importance of maintaining diversity through cultural practices.  相似文献

Since the United Nations’ establishment of the Millennium Development Goals (MDGs) in 2000 the world has observed an increasing trend in foreign aid provided by more affluent countries to developing nations. This paper examined whether foreign aid (total foreign aid and health sector aid) has been effective in improving the health of citizens in recipient nations since establishment of the MDGs. Five facets of population health were examined: infant mortality, life expectancy, the annual death rate, and immunizations against measles and diphtheria. Using a panel data set covering 90 developing countries, observed annually over 2001–2015, fixed-effects multivariate regressions with alternative specifications were estimated for each of these measures. The findings reveal that foreign aid has had little to no effect on population health since 2000. We found some evidence that foreign aid has improved life expectancy in developing countries, however, the effect is very small. In light of these findings, continued monitoring of the relationship between foreign aid and health outcomes would be both valuable and prudent.

This case study of tanneries in Kasur presents an account of industrial transformation of an agrarian society in a developing country, Pakistan, with its effects, efforts to rehabilitate and the difficulties faced in abatement of pollution. The research attempts to respond to the question of the social and economic cost of achieving pollution abatement in Kasur and develop a viable model. The research methods adopted include reviews of secondary data, personal interview and sample survey of tanneries in the study area. The results reveal how people have grappled with the problem of pollution abatement from the tanneries in Kasur and in creating decisive awareness at the local, national and international levels. The transformation of the city from a commercial centre to a semi-industrial tanning centre has led to a loss of 30% cultivable area due to contamination. It is reported that crop yield has dropped by 50% over the past 10 years. The total loss of agricultural income is estimated to be $450 thousand US per annum. The environmental impact of tanneries is highly pronounced in the urban areas around the leather tanning industrial units. Strong protest by the affected population has to some extent forced industrialists to rehabilitate the environment. NGO and the Government are also contributing to this effort. The case study of Kasur presents an example of the community's efforts to mobilize its local, financial and political resources to overcome the environmental hazards, with the associated problems and dilemmas.  相似文献
