Using a time-varying GJR copula approach, we determine the conditional dependence of the GCC stock indices on oil price between 2007 and 2016. We show how to improve the forecasting accuracy of the co-movement of energy and stock prices in an equally weighted portfolio. Contrary to prior findings, we demonstrate that due to the different co-movements across the GCC stock indices, portfolios of oil assets and several GCC stocks are less likely to be affected by systemic risk. The different co-movements across several stock indices over time provide different entry and exit points for stock investors. This approach is in line with the ‘buy low/sell high’ adage. 相似文献

A new approach to valuing ecosystem goods and services (EGS) is described which incorporates components of the economic theory of value, the theory of valuation (USappraisal), a multi-model multiple criteria analysis (MCA) of ecosystem attributes, and a Delphi panel of experts to assign weights to the attributes. The total value of ecosystem goods and services in the various tenure categories in the Wet Tropics World Heritage Area (WTWHA) in Australia was found to be in the range AUD$188 to $211 million year−1, or AUD$210 to 236 ha−1 year−1 across tenures, as at 30 June 2002. Application of the weightings assigned by the Delphi panelists and assessment of the ecological integrity of the various tenure categories resulted in values being derived for individual ecosystem services in the World Heritage Area. Biodiversity and refugia were the two attributes ranked most highly at AUD$18.6 to $20.9 million year−1 and AUD$16.6 to $18.2 million year−1, respectively. 相似文献

文章主要研究养老基金最低收益保证制度及其框架下的资产配置问题.利用鞅方法创新性地给出了最优资产配置策略,随后分析了最低收益保证制度对最优资产配置的影响.结果表明,外部机构的利润分享比例越大,保证额度越高,养老基金投资风险资产的比例越高,但随着时间的推移,其风险投资将逐步降低.最后,文章利用所得结论为我国设立最低收益保证制度提供了建议:即我国应设立相对额度的最低收益保证制度;应由政府部门或非盈利机构提供这种最低收益保证,且不宜采取利润分享原则;保证额度应适度,过高会导致养老基金的投资风险过高,而过低则达不到稳定退休者收入的效果. 相似文献

Green net national product was thought to be one way of measuring sustainable income. However, David Pearce understood that
a better measure of sustainable development was to look at what a generation is leaving in form of capital assets to later
generations. In this article, his arguments and insights are highlighted against recent theoretical advances. 相似文献

Prices and Regional Variation in Welfare 总被引:1,自引:0,他引:1
Daniel T. Slesnick 《Journal of urban economics》2002,51(3):446
One would expect regional differences in prices to influence conclusions concerning levels and distributions of well-being. Although there is anecdotal evidence of significant price dispersion across regions, there is no governmental source of data that measures differences in price levels. In this paper I integrate estimates of regional prices with expenditure data from the Consumer Expenditure Surveys to assess the influence of price differences on living standards in the United States. While prices have little effect on inequality, estimates of poverty and the standard of living change substantially with the inclusion of regional price variation. 相似文献

资产证券化是金融创新浪潮中崛起的一种主流融资技术。它使贷款成了具有流动性的证券,盘活企业的存量资产,并优化其财务比率。然而,也相应地引发了一系列的会计问题。主要集中在转让方式或出售方式的会计确认、定价计量、会计报表合并及报表披露。 相似文献

Previous studies of UK house prices, developed from the demand and supply ofhousing or from the asset market approach have been poor in terms of robustness and ex-post forecasting ability. The UK housing market has suffered a number of structural changes, particularly since the early 1980s with substantial house price increases, financial market deregulation and the removal of mortgage market constraints through competition. Consequently, models which assume that the underlying data-generating process is stable and apply constant parameter techniques tend to suffer in terms of parameter instability. This article uses the Time Varying Coefficient (TVC) methodology where the underlying data-generating process in the UK housing market is treated as unstable. The estimation results of the TVC regression of UK house prices is compared with those obtained from three alternative constant parameter regressions. Comparisons of forecasting performance suggest the TVC regression out-performs forecasts from an Error Correction Mechanism (ECM), Vector Autoregressive (VAR) and an Autoregressive Time Series regression. 相似文献

根据美林证券的投资时钟理论,结合我国宏观经济的月度指标,将我国宏观经济状态划分为四个阶段,同时将全国社会保障基金的投资细分为10个类别的风格资产,基于经济周期视角对这10类风格资产的收益率状况进行分析,结果表明:在复苏阶段,股票资产的收益率最高,并且不同风格股票在收益率方面的差异不大,表现出齐涨的态势;在过热阶段,不同风格股票在收益率方面表现出较大的差异,小盘股的收益率表现最好,尤其是小盘成长股的收益率最高;在滞胀阶段,最安全的资产应该是现金资产,倘若考虑到通货膨胀率的因素,其实际收益率甚至为负;在衰退阶段,债券类资产的表现最好。同时,基于不同策略的资产配置方案的累计收益率比较结果表明:不同经济周期下的资产配置方案可以显著提高资产组合收益率。 相似文献
