伯南克货币政策主张及其影响-分析与预期 总被引:2,自引:0,他引:2
Lu Xiaoming 《国际金融研究》2006,(3)

日本结束量化宽松货币政策的影响分析 总被引:4,自引:0,他引:4
2006年3月9日,日本银行宣布终止实行了5年之久的“量化宽松”政策。朝最终升息跨出了第一步,原因是日本经济从2005年起出现了比较明显的好转,如果再继续实行超宽松的货币政策有可能引发通胀。日本央行这次顶住了政府压力做出改变货币政策的决定, 凸现其独立性进一步提高。在目前状况下日本货币政策的改变对日本经济和全球经济都具有积极影响,对资金流动和金融市场的影响更大,尤其是将提高日本金融市场的吸引力。 相似文献

房地产投资项目融资风险的灰色模糊评判研究 总被引:6,自引:0,他引:6
房地产投资项目的融资风险问题具有灰色性(信息不完全)和模糊(概念不明确)性。考虑到灰色性和模糊性的影响,采用适用性更广的灰色模糊多级综合评判理论,对房地产投资项目融资风险的多级指标体系进行综合评判,可以有效地、全面地和系统地评价房地产投资项目融资风险的大小,为项目融资项目决策提供准确依据。 相似文献

Infrastructures of surveillance—everyday, taken-for-granted, institutionalized and technically mediated practices which identify, observe, and analyze individual actions—permeate society. These infrastructures mediate the production of social knowledge and action toward individuals. This article examines the genesis of one such infrastructure, namely the coordinated practices of identifying and locating mobile phone users during emergency (9-1-1) calls. Implementing this infrastructure has entailed creating and coordinating systems to locate wireless phones, to deliver the emergency calls to the appropriate service agency, and to deliver appropriate services to the emergency event. This implementation has occurred within historically specific regulatory, political, cultural, technological, and economic contexts and has specific implications for general surveillance practice. Focusing primarily on the state of Texas, this article examines the development of systems which store and deliver individuals’ geographic location. It argues that, despite privacy laws tightly restricting the use of information generated in the 9-1-1 process, and despite the special purpose to which the 9-1-1 system is dedicated, the wireless 9-1-1 initiative has created the infrastructure for a general purpose locational surveillance infrastructure capable both of surveilling broad patterns of activities and of responding to particular individuals. Moreover, the infrastructure is more available to police agencies and to well-established and well-funded corporate entities than to grass roots organizations. This trend is driven by the need to coordinate a national emergency response system within a fractured telecommunication industry, by the desire of marketers to understand and address their customers’ habits of mobility, and by an increasing willingness of police agencies to include widespread surveillance under the rubric of “emergency services.” Policy responses such as greater ability to opt out of the surveillance system, public oversight of emergency operations, and greater public access to the infrastructure itself might mitigate the most harmful potential social effects of this infrastructure, while distributing its benefits in a more democratic and egalitarian way. 相似文献

国家明确以税收优惠的形式鼓励和引导企业和个人参加企业年金计划,并于2014年实施了个税递延政策。基于指标模型构建和数据模拟,本文对我国企业年金在个税递延政策实施前后的保障水平进行了比较,通过参数敏感性分析考察了投资收益、工资增长、退休年龄和缴费比例等因素的影响。研究发现,实施个税递延政策后企业职工的养老保障水平在较大程度上低于政策实施前,但不同性别、不同收入水平和不同缴费比例的企业职工保障水平降低的程度有所差异。收入水平和缴费比例越高的男性职工,个税递延政策实施后保障水平降低的幅度越高,但对女性职工而言,这种影响要弱一些。进一步,可以通过增加投资收益、延迟退休年龄和提升缴费比例等方法来提高企业职工的养老保障水平,这与目前正在进行的一系列改革方向也一致。 相似文献

At the beginning of the 21st century, the Netherlands and Flanders introduced a risk-based approach to flood risk management (FRM), labelled as multi-layer (water) safety. In contrast to a flood defence approach, risk-based management stresses the need to manage both the consequences and probability of a flood. The concept has developed differently in the two countries, as we conclude from a discursive-institutionalist research perspective. The Netherlands is characterised by a high institutionalization of the traditional flood defence discourse and a more closed policy arrangement, whereas in Flanders, the flood defence discourse is less institutionalized and the arrangement is more open. In both countries we see an opening of the arrangement preceding the establishment of multi-layer (water) safety, but at the same time, actors stress different aspects of the concept in order to increase its compatibility with the existing policy arrangement. In the Netherlands, the focus is on probability management, in Flanders on consequence management. In the Netherlands, multi-layer (water) safety as a concept could be established because it stabilises the system in the short-term by reinforcing the importance of flood defence, whereas in Flanders, policymakers were receptive to the concept because it supports a shift of responsibility towards actors outside traditional water management. 相似文献

This paper studies the income fluctuation problem without imposing bounds on utility, assets, income or consumption. We prove that the Coleman operator is a contraction mapping over the natural class of candidate consumption policies when endowed with a metric that evaluates consumption differences in terms of marginal utility. We show that this metric is complete, and that the fixed point of the operator coincides with the unique optimal policy. As a consequence, even in this unbounded setting, policy function iteration always converges to the optimal policy at a geometric rate. 相似文献

Public investment decision-making processes involve multiple and interrelated sectoral and regional policy objectives and budget constraints. This paper presents a dynamic spatio-economic model that considers multi-sectoral investment interdependencies using data at the prefecture level in Greece. The expenditure allocation dynamics of most types of regional public investment are found to be competitive with each other. This outcome is attributed to the lack of policy coordination, technological and budget constraints, geographical factors, and equity and political considerations. The investment interrelationships may have a significant effect on future state funding needs and the strategic assessment of infrastructure development at the country level. 相似文献

货币政策支持实体经济高质量发展的关键在于疏通货币政策传导机制,引导流动性进入重点领域和薄弱环节,因此货币资金的配置效率至关重要。本文基于交互效应面板分位数回归,测度货币政策对实体企业流动性的异质性效应。研究发现:在样本期内,实体经济流动性配置陷入了资金越充裕的企业越易于获得融资,越易于获得融资的企业资金越充裕的窘境。这种流动性配置的“马太效应”具体表现为,货币政策对尾部企业的支持力度不及头部企业的一半;虚拟经济对尾部企业的“分流效应”高达头部企业的3倍,从而强化了流动性配置的失衡。因此,当前密集出台的一系列普惠政策有助于提升流动性配置效率,进一步完善调控模式的关键在于健全现代化金融体系,增强货币政策的靶向性和针对性。 相似文献
