基于双基准与多风险制度下的中国外汇储备币种结构配置研究 总被引:4,自引:0,他引:4
内容借鉴Markowitz基本均值方差模型的思想,本文运用基于双投资基准和多风险制度的投资组合模型对我国外汇储备币种结构配置进行了实证研究。本文首先从中国实际出发确定了两个投资基准和三种风险制度,进而在此基础上实证研究了在不同投资基准、不同风险制度和不同风险厌恶度情况下的我国外汇储备币种结构。最后,本文提出在不同风险制度转换过程中所对应的我国外汇储备各币种所占比重的调整方向。 相似文献

本文关注经济环境与调控政策等共同冲击对区域房价的影响,强调重大事件与我国房地产市场变动的内在关系;试图从同期相关视角出发,构建区域房价的共同因子模型,并利用2002第一季度至2012第四季度省际面板数据进行实证分析。结果表明:(1)区域房价受经济环境与调控政策两个因子影响;(2)相对于其它经济事件,次贷危机对我国各地区房价的影响最大,相对于其它时期的房价调控政策,2003年-2008年的调控政策更为有效;(3)各地区对共同冲击的反映是异质的。从而,政府在制订房价调控政策时应充分考虑市场反应,以促进房地产市场的协调平稳发展。 相似文献

In this paper, we examine the stock market integration process amongst 17 Economic and Monetary Union (EMU) countries from January 2002 to June 2013 over a normal period as well as for the Global Financial Crisis (GFC) and Eurozone Debt Crisis (EDC) periods. We classify the economies in three groups (A, B and C) based on their GDP to examine whether the economic size influences financial integration. Seven indicators are used for the purpose, namely, beta convergence, sigma convergence, variance ratio, asymmetric DCC, dynamic cointegration, market synchronisation measure and common components approach. The results suggest that large-sized EMU economies (termed as Group A) exhibit strong stock market integration. Moderate integration is observed for middle-sized EMU economies with old membership (termed as Group B). Small-sized economies (termed as Group C) economies seemed to be least integrated within the EMU stock market system. The findings further suggest presence of contagion effects as one moves from normal to crisis periods, which are specifically stronger for more integrated economies of Group A. We recommend institutional, regulatory and other policy reforms for Group B and especially Group C to achieve higher level of integration. 相似文献

This paper aims to examine the interaction between firm's new product preannouncement (NPP) strategies and consumers' regulatory foci on their WOM intention and the underlying mechanisms. In three experiments, we find that (1) the promotion-focused (prevention-focused) consumers have higher WOM intentions for vague (specific) NPP; (2) curiosity (outcome expectancy) mediates the effects of the NPP strategies on WOM intention for promotion-focused (prevention-focused) consumers; and (3) brand familiarity plays a moderating role, such that the interaction effect between NPP strategy and regulatory focus on consumers' WOM intention holds for a low-familiarity brand only. Our research contributes to a better understanding of NPP strategies and provides actionable strategic support for firms to conduct NPP. 相似文献

金融资管业务往往通过民事合同的安排来达到降低交易成本、规避金融监管的目的。为了防范金融风险,金融监管机构通过《资管新规》等一系列监管政策加强对金融市场的"穿透式"监管。金融商事审判机关在制定法没有明确规定的情况下,如何针对违反监管政策的金融交易合同做出公允的裁判是亟须解决的问题。本文分析了合同法第53条3、4、5款的适用空间为何,以及金融商事审判如何在现行法的框架内防范实现风险防范的目的。 相似文献

Increases in government spending trigger substitution effects—both inter- and intra-temporal—and a wealth effect. The ultimate impacts on the economy hinge on current and expected monetary and fiscal policy behavior. Studies that impose active monetary policy and passive fiscal policy typically find that government consumption crowds out private consumption: higher future taxes create a strong negative wealth effect, while the active monetary response increases the real interest rate. This paper estimates Markov-switching policy rules for the United States and finds that monetary and fiscal policies fluctuate between active and passive behavior. When the estimated joint policy process is imposed on a conventional new Keynesian model, government spending generates positive consumption multipliers in some policy regimes and in simulated data in which all policy regimes are realized. The paper reports the model's predictions of the macroeconomic impacts of the American Recovery and Reinvestment Act's implied path for government spending under alternative monetary–fiscal policy combinations. 相似文献

The greening of organizational transportation fleets, especially trucks and automobiles, has gained increasing attention by companies in a variety of industrial sectors. The reasons for this concern and attention are due to regulatory and competitive pressures, but also increasing costs of fossil-fuels. Surprisingly the amount of research and modeling for fleet management overall has been rather limited, with the focus on managing green vehicle investments virtually non-existent. In this study we develop a two-stage game theoretic model that helps evaluate, from both policy and organizational perspectives, the implications of greening of transportation fleets. Various parameters are evaluated including factors such as innovations in green vehicle technology, levels of service differences, cost of fuel, adjusting tax policy, regulatory compliance requirements, and adaptation costs. This evaluation provides practical insights into actions that could be considered by regulators and organizations to encourage environmental investments. 相似文献

调节聚焦作为个体实现目标的动机调节系统,对个体创新行为具有重要作用,是组织行为学领域关注的热点。基于调节聚焦等相关理论,从二维视角深入考察个体调节聚焦对其双元创新的过程机理与边界机制。对527名国防科技研发人员进行问卷调研分析,结果发现:①促进聚焦和防御聚焦均正向预测双元创新及其平衡性与互补性,促进聚焦的预测作用更强;②探索式失败学习和利用式失败学习同时中介上述关系;③正向组织差错管理氛围正向调节促进聚焦与双元创新及其互补性的关系,负向组织差错管理氛围正向调节防御聚焦与双元创新及其互补性的关系。 相似文献

在中国现行的城市规划体系框架中,各层次规划的主要作用都是为了控制和引导城市合理、有序地发展.在城市规划领域里,可以分配的最重要的社会资源是城市土地的开发权以及在城市土地使用关系上建立起来的各种城市空间关系,这使得控制性详细规划成为实施规划管理的核心内容和直接依据.文章对控制性详细规划编制中的"现状调查"、"区域分析"、"指标确定"以及控规中的城市设计等问题进行了一定的探讨,并引入实例,以期对当前控制性详细规划体制的进一步完善起到一定的促进作用. 相似文献

This paper presents tests for the null hypothesis of no regime switching in Hamilton’s (Econometrica 57:357–384, 1989) regime
switching model. The test procedures exploit similarities between regime switching models, autoregressions with measurement
errors, and finite mixture models. The proposed tests are computationally simple and, contrary to likelihood based tests,
have a standard distribution under the null. When the methodology is applied to US GDP growth rates, no strong evidence of
regime switching is found.
