美国第二轮量化宽松政策实效分析

本文对美国第二轮量化宽松政策实效进行分析,认为总体上该政策取得了一定的成效,表现在一些部门投资扩大,耐用消费品支出增加,股市出现价格指数上升趋势。但是,房地产市场复苏缓慢,建筑投资依然低迷;工薪收入增额下降和较高失业率的存在,以及对未来经济前景的信心不足,使得个人消费支出难以迅速扩大。此外,该政策推动了国家债务规模进一步扩大,政府信用等级下降,投资者风险增大,这些因素反过来进一步使得投资者信心不足,就业岗位创造艰难,GDP增长疲软。该政策虽使金融市场流动性增加,但促进投资、刺激消费的两大目标并未充分实现。

循环赛理想轮次编排算法研究

以往循环赛轮次编排方法可以分为两类：一类是每次轮转一个位置;另一类是每次轮转多个位置。到目前为止,还没有一种轮次编排方法能够同时满足各队每两场比赛理想间隔场次和有秩序交替＂先后＂等多种需求。此外,各项目也没有统一的循环赛轮次编排方法。通过研究,借鉴棋类积分编排方法,我们提出了＂先后分配算法＂。利用这种算法可以完善循环赛轮次编排方法,使循环赛轮次编排能够同时满足多种需求,并实现各项目统一的循环赛轮次编排方法。虽然该算法目前还没有在计算机编排软件上得到运用,但可以为研究人员提供参考。

YB65条盒包装机吸纸轮负压控制改进

针对YB65型硬条包装机负压控制阀及凸轮装置安装在机身内部容易出现管路渗油、条盒纸吸取故障较多、维修保养费时费力的现象,通过对YB65型硬条包装机负压控制阀及凸轮装置进行重新设计,将原负压控制阀改为电磁阀,将原凸轮装置改造成可调凸轮并安装在机身外部,达到调整凸轮相位方便快捷,极大降低维修调整的时间,并能有效解决硬条包装机负压管路渗油问题。     

New Powers and the Distribution of Preferences in Global Trade Governance: From Deadlock and Drift to Fragmentation

ABSTRACT

Existing theories make divergent predictions about the impact of new powers on the global political economy. Some argue that a more even distribution of power will erode international cooperation, while others argue that cooperation can continue with the help of international institutions to overcome collective action problems. We argue that this debate overlooks a critical determinant of the shape of power transitions: the distribution of preferences amongst the major powers. It is primarily in the context of divergent preferences that power transitions are likely to give rise to conflict. Moreover, even where preferences diverge, the gains of cooperation provide a strong incentive to continue to pursue goals through multilateralism. This situation leads to forms of institutional change unanticipated by established theories. These include deadlock in expansive multilateral fora, institutional drift as old rules cannot keep up with the changing political and economic context, and fragmentation as countries seek minilateral solutions that reduce preference diversity. We develop this preference-based, institutional argument by examining the distribution of preferences and institutional change at the World Trade Organization (WTO) and its Doha Round, where the power transition is relatively advanced.     

The Domestic Sources of Multilateral Trade Negotiations: Explaining Brazil's Negotiating Position in the Doha Round

This article investigates the effects of a transfer between two countries participating in a customs union. This analysis yields very paradoxical results which differ from the conclusions obtained by the traditional literature which has been developed in a two-country framework or in a multilateral world but with universal free trade. The compensation scheme adopted by the authorities of the customs union may create an overall terms of trade deterioration and induce an impoverishment for both member countries. Thus, transfers may not be an adequate instrument to redistribute the gains of economic integration between the members of a free trade association.

《关贸总协定》第24条的再解读--规则、案例和展望

《关贸总协定》第24条所规定的区域贸易安排是世贸组织框架下最惠国待遇的例外。区域贸易安排一方面有贸易促进的积极作用,另一方面又因其集团间歧视的特征,一旦被滥用,就会侵蚀世贸组织的非歧视原则,背离关贸总协定/世贸组织实现全球贸易自由化和一体化的目标。《关贸总协定》第24条、乌拉圭回合的《谅解》以及土耳其案的专家组、上诉机构的论述都显示了世贸组织对区域贸易安排越来越多的关注,但现有的制度仍有一些不足,文章从对规则的分析入手,从区域贸易安排与世贸组织的关系定位、争端解决机制、区域贸易协定审查委员会的审查等方面对世贸组织框架下区域贸易安排的完善提出若干建议。
