This paper demonstrates the utilization of wavelet-based tools for the analysis and prediction of financial time series exhibiting strong long-range dependence (LRD). Commonly emerging markets' stock returns are characterized by LRD. Therefore, we track the LRD evolvement for the return series of six Southeast European stock indices through the application of a wavelet-based semi-parametric method. We further engage the á trous wavelet transform in order to extract deeper knowledge on the returns term structure and utilize it for prediction purposes. In particular, a multiscale autoregressive (MAR) model is fitted and its out-of-sample forecast performance is benchmarked to that of ARMA. Additionally, a data-driven MAR feature selection procedure is outlined. We find that the wavelet-based method captures adequately LRD dynamics both in calm as well as in turmoil periods detecting the presence of transitional changes. At the same time, the MAR model handles with the complicated autocorrelation structure implied by the LRD in a parsimonious way achieving better performance.  相似文献

The rationale for the growth of nonprofit management education in the United States has recently been charted by O'Neill (2005). Ten years previously, the United States and the United Kingdom were at similar levels of development. By 2006 the parallel lines had been broken. Why has nonprofit management education expanded in the United States while provision of graduate education for the voluntary sector in the United Kingdom has stood still? This article explores the factors that have prevented parallel growth in education provision. It argues that the university as an institution, both in terms of its nature and its power structures, is one of those factors. It presents the story of the closing of the world's first voluntary sector course at the London School of Economics and concludes with reflection on the likely future of voluntary sector management education provision in the United Kingdom.  相似文献
