Delegation and polarization of platforms in political competition

Summary. We consider a model of political competition among two ideological parties who are uncertain about the distribution of voters. The distinguishing feature of the model is that parties can delegate electoral decisions to candidates by nomination. It is shown that if the credible platform commitments of the candidates is feasible, then at least one of the parties nominates in equilibrium to a candidate who has an ideology that is more radical than the delegating party's ideology. In a variety of circumstances, this, in turn, yields a polarization of equilibrium policy choices of the candidates. It is thus argued formally here that strategic nomination of the candidates may well be one of the major reasons behind the well documented observation that the platforms associated with the political parties in two-party democracies are often surprisingly polarized.

Self-enforcing international environmental agreements with a stock pollutant

In this paper the stability of an International Environmental Agreement (IEA) among N identical countries that emit a pollutant are studied using a two-stage game. In the first stage each country decides noncooperatively whether or not to join an IEA, and in the second stage signatories jointly against nonsignatories determine their emissions in a dynamic setting defined in continuous time. A numerical simulation shows that a bilateral coalition is the unique self-enforcing IEA independently of the gains coming from cooperation and the kind of strategies played by the agents (open-loop or feedback strategies). We have also studied the effects of a minimum participation clause finding that for this case a self-enforcing IEA just consists of the number of countries established in the clause.JEL Classification: C73, D62, Q28 Corresponding author : Santiago J.

北京市下岗职工的再就业分析

该文利用独自收集到的有关北京市下岗职工的样本数据,分析了影响下岗职工失业持续时间的原因,探讨了影响下岗职工再就业前后收入变化的原因.通过分析得出以下主要结论:第一,下岗政策虽然在一定程度上促进了劳动力市场的形成,但随着下岗职工失业持续时间的延长,下岗政策已成为阻碍劳动力市场化的因素,同时也妨碍了市场经济体制下社会失业保障体制的建立和完善.第二,为了使更多的有在传统体制下工作经历的下岗职工,尤其是大量从事过企业管理工作的下岗职工尽快地实现再就业,不仅需要对他们进行各种技能的培训,而且更需要对他们进行如何适应新的经济环境的再教育.第三,"下岗"不仅是中国经济体制转型过程中的一个特殊时期的政策,实际上也是结构性失业在中国特有经济体制中表现出来的一种特有的现象.对于这种由于产业结构变化带来的失业问题,政府有必要制定更多的积极性的失业政策.     

西方融资担保理论综述

西方融资担保理论经过20多年的迅速发展，已经成为微观金融领域最活跃、最成功的重要分支之一。但国内对这一理论仍比较陌生，有价值的研究还很少。但随着中国利率市场化改革步伐的加快及利率竞争的日益加剧，担保作为最重要的非利率因素，势必将成为金融机构之间竞争的另一重要要素。为此，本文围绕担保的经济功能和意义，从公司治理、债务契约和宏观经济等视角系统介绍了融资担保理论的主要进展情况，最后对这一理论的前沿问题及在中国的借鉴与应用进行了简要评述。

中国通货膨胀的福利成本研究

通货膨胀一直以来都是衡量一国宏观经济运行是否稳定和健康的重要指标。本文对国内外关于通货膨胀福利成本的研究发展进行了较为完整的综述,并在此基础之上运用消费者剩余方法和新古典宏观经济学一般均衡模型对中国通货膨胀的福利成本进行了计算和比较。实证结果说明,在中国高通货膨胀会带来较高的福利损失,因此将通胀率保持在较低的水平对提高中国的经济福利水平是有利的。     

风险承担、风险缓冲与管理理念——关于信托公司风险管理的思考

由于信托制度的独特设计,信托公司或直接或间接均要承担信托财产损失风险,从近期来看,信托公司应构建以资本金为核心的风险缓冲机制。从长期来看,引入业绩评价基准,进行相对业绩评价是信托公司风险缓冲的必然选择。信托公司在风险管理时应树立两个理念,一是要将风险管理列为企业管理活动的核心,二是要认识到风险管理是一项长期性的工作,不能寄希望“毕其功于一役”。

我国上市公司关联交易的动因及监管

上市公司关联交易呈持续上升的态势。关联交易的发生有其客观基础和必然性，它为上市公司规避税负、转移利润、取得公司控制权、形成市场垄断、分散或承担投资风险等提供了合法的途径，但关联交易有可能损害非关联股东和债权人的利益，进一步对证券市场构成严重危害。应加强对上市公司关联交易的监管：在政策导向上，控制并不断减少由于历史和体制原因而形成的大量不合理的关联关系和交易行为，抓住源头，综合治理；针对关联交易中出现的新问题，适时调整和完善相关法规及监管方式和手段，对上市公司的关联交易行为进行更加具体和有效的规范。
