Recent evidence suggests shifts (structural breaks) in the volatility of returns causes non‐normality by significantly increasing kurtosis. In this paper, we endogenously detect significant shifts in the volatility of oil prices and incorporate this information to estimate Value‐at‐Risk (VaR) to accurately forecast large declines in oil prices. Our out‐of‐sample performance results indicate that the model, which incorporates both time varying volatility (without making any distributional assumptions) and shifts in volatility, produces more accurate VaR forecasts than several benchmark methods. We make a timely contribution as the recent more frequent occurrences of unexpected large oil price declines has gained significant attention because of its substantial impact on the financial markets and the global economy.  相似文献

Rapid population ageing increases interest in economic flows across ages and intergenerational transfers in general. This article uses the National Transfer Accounts methodology to measure consumption and production at each age, and how the difference between consumption and production is financed through (private and public) transfers and the interaction with assets, i.e. ‘asset-based reallocations’. During working ages, people earn more than they consume and with the surplus they finance the deficit of the young and old generations who consume more than they produce. Such a pattern of economic dependency is universal across countries and across time, but huge differences exist in the ages at which individuals produce more than they consume and vice versa. Moreover, the importance of private and public transfers and asset-based reallocations varies across countries and times. In the last three decades, life expectancy at birth in Slovenia increased by 9.3 years, while the age span in which production exceeds consumption narrowed rather than increased. Child dependents are predominantly financed by private transfers, whereas the elderly mainly rely on public transfers. Young and old individuals increasingly rely on public transfers. Together with rapid population ageing, this is likely to jeopardise the public finance system in the future.  相似文献

This paper critically examines the ‘asset transfer’ of leisure services from the public to the voluntary sector. Asset transfer might be theorised as ‘austerity localism’, in which volunteers are obliged to fill the gaps left by retreating public provision, or as ‘progressive localism’, which represents new opportunities through the localism and Big Society agendas to develop more locally responsive, cooperative and mutualist visions. In this way, asset transfer might overcome the limitations of the United Kingdom policies in which ‘Big Government’ is replaced by civic society. Drawing on qualitative interviews with key personnel (volunteers, managers and local authority officers) at 12 leisure facilities, a grounded assessment of the nuanced balance between ‘austerity localism’ and ‘progressive localism’ is provided, including three observations. First, the main impetus for transfer was cuts in local authority budgets which stimulated the emergence of local groups of volunteers. Secondly, the transfers themselves required interaction between local government and the volunteer groups; however, the nature of the relationship and support given varied and support was limited by austerity measures. Thirdly, volunteers do not automatically fill a gap left by the state: without support transfer viability relies on the financial and social capital among volunteer groups, and this is unevenly distributed. These findings suggest that the capacity for a ‘progressive localism’ to emerge through asset transfer is limited. However, where transfer has occurred, there are some progressive benefits of volunteer empowerment and a more flexible service.  相似文献

当市场环境不好以及不确定性增加时,基金进行安全投资转移。企业积极履行社会责任所形成的声誉资本具有“类保险”作用,在面临负面事件或不确定性环境冲击时能够防止股价大幅下跌和市值损失;基金是否会在市场环境不好时将投资组合转向社会责任绩效更高的股票进行安全投资转移呢?使用2010—2017年开放式基金样本,实证检验了企业社会责任、市场环境与安全投资转移之间的关系。研究发现,在市场环境表现不佳时,基金避险需求增加,倾向将投资组合更多地转向社会责任绩效高的股票进行安全投资转移;进一步研究发现基金和基金经理特征影响基金的安全投资转移行为,净资金流入较少、历史业绩差、经理选股能力差的基金根据企业社会责任进行安全投资转移的程度大。研究还发现,基金的安全投资转移行为对基金业绩和基金收益波动产生了积极影响。  相似文献

研究目的:分析非住宅建设用地使用权续期活动的规则与性质,提出完善续期规则的建议。研究方法:规范分析法,比较分析法。研究结果:非住宅建设用地使用权的续期规则存在疏漏,使续期申请的起止期间难以清晰界定,以私法视角理解续期活动也不妥当。研究结论:续期是申请人取得重新设立的建设用地使用权的过程,因此要求在续期过程中必须清晰界定续期权利的设立与灭失期间,保证续期或救济得以顺利进行。续期也是获得行政特别许可的结果,应当采用协议出让方式予以确认。  相似文献

While there is a prevailing rich body of studies on the role of university knowledge transfer office (KTO) in the commercialization process as part of the Third Mission, research on its role in community engagement activities is relatively neglected, even as funding agencies and policy makers conceive these as instrumental to sustaining social and economic development. This article focuses on the role of university KTO in supporting, facilitating or undertaking Third Mission community engagement activities. Drawing on data from the annual Higher Education Business and Community Interaction survey for the years 2007–2012, this paper empirically explores the relationship between a range of Third Mission activities by university KTO and performance of three key business-community services – provision of consultancy, provision of continuous professional development courses (CPD), and leasing of facilities and equipment (FE). It emerges that the routines of developing strategic plan and creating spin-off are positively associated with all types of community knowledge transfer (CKT) activities. Further, the routines of establishing partnerships with local and regional bodies, and licensing are positively related to CPD and FE, respectively. The article is concluded with implications for theory, practice, policy, and suggestions for future research.  相似文献

The conventional argument that the introduction of transfer of development rights (TDR) shifts the power of land use regulation from the state to the market is increasingly under challenge. In China, the state's grip on land is reinforced through TDR, in which the state is both regulator and player. This state-dominated form of TDR affects China in three ways. First, competing aspirations of different scales of government complicate how TDR is implemented. Although the central state promotes TDR to maintain a national balance of arable land, some local states instrumentalize it to expand their landed basis of accumulation. Secondly, TDR tends to benefit the state but not its people. It may increase the fiscal income of the sending government and lessen the land shortage of the receiving government, but sometimes at the expense of the interests of land users without land ownership. Thirdly, given the state's deep involvement in TDR programs, the key for China's TDR to protect arable land lies not so much in clear property rights or a fully fledged market as in effective checks and balances regarding the state's powers over TDR. These three observations attest to the embeddedness of TDR in the local political economy.  相似文献

在"一带一路"倡议下,人民币国际化的原油计价面临着重大机遇:中国与"一带一路"沿线能源出口国利益互补、亚洲缺少原油定价中心、全球出现"去美元化"的趋势以及人民币国际化具备强有力支撑等条件,但同时也面临着资本管制与原油期货市场流动性的冲突、较低开放度的中国金融市场无法为人民币提供畅通的回流路径以及"新特里芬难题"等挑战。借鉴相关发展经验,应积极推进人民币原油期货市场建设、推进金融市场开放构建人民币环流、扩大与"一带一路"沿线国家(地区)的贸易往来、借助基础设施建设强化人民币计价功能等,努力实现人民币国际化的原油计价。  相似文献

Acknowledging the sharp growth of Chinese state‐affiliated multinationals and their strategic asset‐seeking investments abroad, this study investigates the effects of headquarters' home‐country political ties on the multinational‐wide benefits gained from subsidiary knowledge transfer in Chinese multinationals. It also looks at how these effects are mediated by organizational distance and social integration between headquarters and subsidiary. Based on a survey of 177 subsidiaries of 99 Chinese multinationals, we find that headquarters' political ties trigger organizational distance and hinder social integration between headquarters and foreign subsidiaries and these, in turn, hamper the potential benefits that Chinese multinationals derive from subsidiary knowledge transfer. This study identifies new challenges related to political ties and light‐touch integration in gaining benefits from subsidiary knowledge transfer.  相似文献
