高凝油自动计量技术

沈阳油田是我国最大的高凝油生产基地,原油的凝固点在45～67℃之间。目前主要采用分离器玻璃管计量油井产量,其缺点是流程复杂,工作效率低,工人劳动强度大。随着沈阳油田的高凝油生产进入了高含水时期,原油伴生气急剧减少,采用玻璃管计量十分困难。针对高凝油生产的特点,该油田研究应用了低油气比的油井计量方式—高凝油自动计量技术,能够优化和简化目前的油井计量工艺,对油井产量进行高效、准确、及时的计量。

论法律不完备性与政府介入期货市场

在期货市场上，法律不完备性问题表现得较为突出，法律对于侵害行为的阻吓作用非常有限、期货市场法律的不完备性，主要取决于期货市场的特点和性质。政府采取相关的监管方式管理期货市场非常必要，监管的介入需要满足标准化和损害（外部性）足够高的条件。政府管理期货市场立法和法院执法的作用不可或缺，但更主要的是采用监管的方式。     

New Labour and Community Protests: the Case of the Govanhill Swimming Pool Campaign, Glasgow

Taking the case study of a community based protest against the closure of a swimming pool in Glasgow, this paper seeks to raise important critical questions about some of the key ideas informing New Labour's urban policy agenda: social capital and active community. It argues that normative notions of active citizenship seriously conflict with bottom-up community protests, highlighting in the process issues of power and inequality. Against claims that New Labour is promoting government through community, here we claim that in the context of this community protest, there was government against community.     

战后日本经济发展中积极财政政策的研究

战后，在实现经济恢复和高速发展过程中，日本政府高度重视财政政策的宏观调控作用，在运用财政政策调节经济方面开辟了一条符合本国国情、突出本国特点的路子．对日本战后积极财政政策进行分析和评价，对我国经济发展具有重要的参考借鉴意义。     

积极财政政策转型与经济增长

近两年来,有关积极财政政策是否应该淡出问题讨论非常激烈。从积极财政实施的时间来看,该政策已经由短期政策转变为中期政策。通过分析当前经济中存在的一些危机现象,认为积极财政政策在一些方面的作用已经减弱。同时,由于积极财政政策在我国实施时间较长,受其它因素的抑制和依赖,又决定该政策此时不宜淡出。因此,为适应经济发展的需要,积极财政政策应该而且必须转型,即转型为稳健的积极财政政策。     

Operations of a Pension Fund after the Asian Crisis: The Thai Experience*

During and after the Asian crisis, institutional investors and pension funds in Asian financial markets have been confronted with a number of difficulties effecting their performance and the way they carry out their role within the national pension system. We analyze these problems by comparing the actual investment policy of an institutional investor with an optimal investment strategy derived from the insights of modern portfolio theory. We also analyze whether the organizational set‐up of a pension fund allows it to adequately perform its role within the pension system. As an example, we examine the operations of the Thai Government Pension Fund (GPF). We find that allowing international investments and reducing restrictions on equity investments while lowering the implicit requirements for investments in government debt would allow the GPF to further diversify its investment risk and to increase its risk‐adjusted return. We also show that some changes in the governance structure of the GPF would lower the occurrence of conflicts of interest for the management and increase the efficiency of the GPF operations.     

基于产出冲击的国际储备需求的跨期均衡分析——真实经济的视角

与现有研究相比,文章从真实经济的角度构造了一个简单的基于代表行为人的跨期均衡模型,探讨基于产出冲击和消费平滑的主动性储备需求的决定。研究表明:主动性储备需求与产出冲击发生的概率、产出冲击大小、代表行为人的相对风险厌恶系数以及代表行为人的主观贴现率呈正向关系,与经济增长速度呈反向关系,而与储备资产的相对价格呈现出非线性的关系。通过数值模拟发现,我国主动性储备约占2007年GDP的6%(相当于我国2007年底国际储备的12%),说明我国近年来增加的国际储备存在较大的被动持有部分,目前的国际储备持有额已经从一定程度上脱离了实体经济的基本需求。因此,除紧缩的货币政策外,我国政府还需要进一步运用汇率政策、贸易政策以及其他干预政策直接降低被动国际储备额。     

Wolf in Sheep's Clothing: The Active Investment Strategies behind Index Performance

This paper argues that the commonly used market indices imply forms of active investment management in disguise. The selection and rebalancing rules make these indices highly exclusive and dynamic regarding their underlying components and significantly bias their performance. Any passive investment tracking these indices turns into an active strategy characterised by market timing and state‐dependent performance. Evidence is provided that exclusive indices outperform (underperform) more inclusive peer indices in upward (downward) markets. The constitution and maintenance rules of exclusive indices correspond to a set of active trading and investment rules similar to momentum strategies.
