This paper examines the behavior of the risk premium component of currency forward rates. Analyzing forward rates of one, two and three-month maturity, we find that the power of forward rate as a predictor of future spot rate decreases with the length of contract maturity. Further, we find that the proportion of the variance of the forward premium which is due to the variation of the risk premium is larger than the proportion due to the expected spot rate change for all currencies except for the Canadian dollar. This proportion also increases with the length of maturity.  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

While univariate nonparametric estimation methods have been developed for estimating returns in mean-downside risk portfolio optimization, the problem of handling possible cross-correlations in a vector of asset returns has not been addressed in portfolio selection. We present a novel multivariate nonparametric portfolio optimization procedure using kernel-based estimators of the conditional mean and the conditional median. The method accounts for the covariance structure information from the full set of returns. We also provide two computational algorithms to implement the estimators. Via the analysis of 24 French stock market returns, we evaluate the in-sample and out-of-sample performance of both portfolio selection algorithms against optimal portfolios selected by classical and univariate nonparametric methods for three highly different time periods and different levels of expected return. By allowing for cross-correlations among returns, our results suggest that the proposed multivariate nonparametric method is a useful extension of standard univariate nonparametric portfolio selection approaches.  相似文献

In this study the authors make efforts to survey the impact of foreign direct investment and trade on the economic growth of five East Asian countries, China, Korea, Malaysia, Philippines and Thailand. Using an augmented production function (APF) growth model, the authors apply panel data Method and data span is from1980 to 2006. The required data are extracted from World Development Indicator 2008. The result shows that a co-integration relationship between growth and its determinants in the APF model is supported. Firstly, the study shows that with the increasing the inflow of foreign direct investment, positive impact on growth in Thailand, Korea and China is proved. However, this impact is negative in Philippine and Malaysia. Also the impact of trade on economic growth has the same result with FDI impact in sign. Further, the impact of labor force on growth is not significant in these countries and the effect of gross fixed capital on growth is positive and has a very high impact on selected countries.  相似文献

The present research proposes a new generalisation of the logistic model aiming at technology diffusion forecasting. Regarding criticisms and failures reported in the literature to apply logistic function for long-term forecasting, in our work we focused on short-term accuracy of forecast. To formulate the model, based on mathematical approximation, at first the differential equation governing the diffusion process is found and then by solving the derived differential equation, the forecast function is obtained. In all steps, mathematical tools from numerical analysis are used. We compared the New Generalized Logistic Model with eight of the most renowned models in the literature. The model led to more accurate fits and forecasts than those obtained from other models we applied for comparison.  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

Using a panel of 69 countries during 1981 and 2005, we investigate the role of institutions in determining foreign direct investment (FDI). We find that institutions are a robust predictor of FDI and that the most significant institutional aspects are linked to propriety rights. Using a novel data set, we also study the impact of institutions on FDI at the sectoral level. We find that institutions do not have a significant impact on FDI in the primary sector but that institutional quality matters for FDI in manufacturing, and particularly in services.  相似文献

This paper examines the risk/return relations in eleven Asian Pacific stock markets and explores if the 1997 Asian financial crisis significantly influenced market behavior in the region. We use a plain vanilla time-series regression approach as well as various GARCH models. Although results significantly vary across model specifications, the overall evidence from GARCH models supports a significantly positive risk/return relation in several markets but only prior to the Asian financial crisis. These results accord with Glosten et al. (1993) and Harvey (2001) and suggest that the relative risk aversion is sensitive to both model specifications and structural breaks.  相似文献
