How can investors build a better portfolio in small open economies? Evidence from Asia’s Four Little Dragons

This study investigates the role of hedging and portfolio design among stocks, exchange rates, and gold in small open economies (SOEs) from 4 January 2000 to 31 March 2020. We adopt the trivariate dynamic conditional correlation-fractionally integrated asymmetric power ARCH model and unconditional quantile regression model, and our findings show that the hedging role of the U.S. dollar (USD) and gold against stocks differs under regular and extreme market conditions. The USD can act as a powerful hedge asset for stocks in regular market periods. Moreover, during the global financial crisis and COVID-19 outbreak, the safe-haven effect of gold becomes stronger for almost all stocks, whereas the USD can serve as a strong safe haven against stock markets of Korea, Taiwan, and Singapore when stock returns are extremely low. In terms of portfolio designing, we find that adding the USD and gold to portfolios improves their hedging effectiveness, and the optimally weighted stock-USD-gold portfolio is the best portfolio strategy, irrespective of referring to return or risk.     

Local fiscal multipliers and spillover effects: Evidence from Philippine regions

Fiscal policy in developed countries has been a rich topic since the Great Recession. However, research has remained limited for developing countries despite their similar use of fiscal policy and concerns about the efficiency of public spending. To help address this research gap, this paper provides a case study of multiplier effects of local government spending in regions in the Philippines as well as spillover effects of local government spending across regions. An instrumental variable based on the country’s intergovernmental transfer system is used to identify regional public spending in panel regressions. The local fiscal multiplier is estimated to be above one, where a 1-peso rise in spending by local government units in a region corresponds to a 1.2-peso rise in regional output. Multiplier effects are highest for capital expenditures and appear to be primarily driven by the services sector. Spillover effects are comparatively large, at around 1.8–2.0, highlighting the important role of domestic trade when stimulating regional economic activity.     

质量屋中相关关系确定的灰关联方法及应用

提出了一种基于灰色关联分析来研究质量屋中顾客需求与工程特性相关关系的方法。运用广义灰色关联分析中的绝对灰色关联分析进一步讨论,通过专家、顾客、厂商综合的打分方法来获得初始的顾客需求以及工程特性的重要度矩阵,然后通过相关的计算来得到绝对灰色关联度,最终得到需求-特性绝对灰色关联矩阵。再通过得到的矩阵进行优势分析,从而确定工程特性重要度的排序以及"瓶颈技术"。最后通过一个具体的实例来说明该方法的运用。     

房价,地方政府与经济人行为逻辑

房价持续快速上涨的原因是多方面的,地方政府的行为值得认真分析,本文认为借助经济人假设能很好地分析地方政府表现出的房价助推行为是为了自身利益的最大化,因此对中央政府的宏观调控不会认真对待.解决这一问题,也应该重视经济人行为逻辑,进行体制改革.     

Using methods of Multi-Criteria Decision Making to provide decision support concerning local bioenergy projects

The public sector plays an important role in the German “Energiewende”. Besides energy management in municipal properties the local government can also support the switch to renewable energy sources through a change in energy supply structures within in their region. Methods of Multi-Criteria Decision Making (MCDM) from Operations Research are helpful regarding that challenge, as they are able to assess the sustainability of local energy concepts, since they not only offer stakeholders the opportunity to participate, but also consider multiple conflicting criteria. In that way, the acceptance of local energy projects and the participation of stakeholders in the decision process are supported. The case study presented in this paper illustrates the results of a MCDM process employed to identify a sustainable bioenergy concept in a rural village in Lower Saxony, Germany. Our analysis revealed not only the opportunities and challenges associated with executing an MCDM process to support the realization of local bioenergy projects, but also discusses potential limitations of the methods.     

基于熵权与改进的TOPSIS法的蔬菜供应商评估研究

蔬菜供应链的基础上,借助于熵权与相关系数矩阵的TOPSIS法相结合的供应商评价模型。首先构建供应商的评价指标体系,然后采用熵权法得到各指标的权重,再结合实例验证该模型的可行性。结果表明该模型能够更客观地对蔬菜供应商的选择进行有效评估。     

论分权背景下的中国垂直管理体制——概况、评价及其完善建议

垂直管理是我国上下级管理体制中的一个重要现象。作为中央对地方、上级对下级进行调控的重要手段,这个现象在中国有不断被强化的趋势。文章认为,为规范垂直管理工作,一要合理划分上下级权限,调动两个积极性。二要设置合理的垂直管理体系,加强对垂直部门的管理。三要转变政府职能,实施科学的干部考评体系。四要推行扁平化治理,扩大下级、基层政府的自主权。     

商业银行网点布局实证研究——以衡水市为例

网点作为商业银行为客户提供金融服务的主要渠道,其布局合理性不仅关系到商业银行经营业绩和竞争力,也关系到社会服务功能的完善。目前,商业银行网点布局随意性和随机性较强,科学的规划和决策不足,资源的浪费和资源配置效率的低下现象突出。实证分析衡水市商业银行网点布局的各种因素,利用数理模型对商业银行网点选址进行分析和优化,以此提高网点布局的科学性与合理性。     

以应对金融危机的视角看我国城市化进程中地方财政困境的化解

全球性金融危机使我国经济遭到严重打击,也给我国带来了巨大的就业压力。笔者以为,当前形势下扩大就业的根本出路在于加快我国的城市化进程,而这一目标的实现又离不开地方财政的支持,然而94分税制后我国地方财政困境已是不争的事实,当前的经济形势又进一步加剧了地方财政的危机,因此,研究如何化解地方财政困境问题已成当务之急。
