为什么国有企业越来越垄断?

近年来,我国的国有企业在产业政策的保护下表现出越来越垄断的趋势。本文运用共同代理模型解释了这种政策倾向的形成原因。代表各个产业部门的利益集团围绕政府的政策展开博弈,政策的形成是政府对各个产业利益集团进行平衡的结果。但是,政府对国有部门的重视程度超过非国有部门。随着国有企业逐渐从许多产业退出,余下的国有部门越来越缺乏其他利益集团的制约,政府因而就倾向于保护这些国有部门的垄断利益。     

流动人口社会救助问题研究

数量众多的流动人口享受不到应有的基本社会保障状况在构建和谐社会的大背景下显得尤为触目惊心.建立流动人口社会救助管理制度具有深远的现实意义.现行流动人口社会救助管理制度是对历史的进步,但存在一定的局限性,应该进一步改革与完善流动人口社会救助管理制度.     

转型时期弱势群体的社会救助

在社会保障制度的建立和发展过程中,社会救助最早建立.但是,现代的社会救助与早期的社会救助有本质上的区别.转型时期弱势群体的社会救助,是建立在一定的法规之上,具有社会性、制度性和强制性的社会保障制度.

Pricing vulnerable options with correlated jump-diffusion processes depending on various states of the economy

In this paper, we use a Markov-modulated regime switching approach to model various states of the economy, and study the pricing of vulnerable European options when the dynamics of the underlying asset value and the asset value of the counterparty follow two correlated jump-diffusion processes under regime switching. The correlation is modelled by both the diffusion parts and the pure jump parts which describe the uncertainty of the value of the risky assets. We develop a method to determine an equivalent martingale measure and a parsimonious representation of the risk-neutral density is provided. Based on this, we derive an analytical pricing formula for vulnerable options via two-dimensional Laplace transforms, and implement the formula through numerical Laplace inversion.     

“四机制工作法”在大学生弱势群体中的运用研究

大学生弱势群体在高校是一种客观存在的社会现象,潜伏着种种危机,是高校和谐校园构建面临的重大课题。本文在大学生弱势群体综述的基础上,提出了＂四机制工作法＂,并将其运用到大学生弱势群体的教育引导中,探讨了＂四机制工作法＂在运用过程中应把握的原则,使其在促进大学生弱势群体成长成才和全面推进和谐校园构建方面具有现实意义。     

弱势群体公共文化服务体系建设研究——基于残疾人公共文化消费状况的调查

满足广大弱势群体的公共文化需求是时下加强和创新社会管理的核心要义之一。文章在对东、中、西部三个城市的残疾人公共文化消费进行调查分析的基础之上,揭示了当前弱势群体在文化权利上面临的困境。研究表明,既有的公共文化服务体系还没有惠及广大弱势群体,当前弱势群体的公共文化消费水平十分低下。其中,个体地位结构因素、区域经济发展水平、社会政策倾斜性配置水平以及无障碍环境是制约残疾人这类弱势群体公共文化消费水平的显著因素。文章认为,要确保弱势群体的文化权利,政府必须加大公共文化服务资源向弱势群体倾斜性配置,构建专业化、社会化的服务供给模式,坚持服务为本的逻辑,构建弱势群体的参与机制,并试点向弱势群体发放文化消费补贴。     

中国农民工的依法维权

通过从五个方面详细论述了农民工群体作为"漂移的社会"的特征,提出农民工的"依法维权"解释模式及其维权特点,认为造成农民工弱势地位不仅有制度方面的原因,也有非法侵害;农民工对"法定权益"的维护会向对"基本权利"的争取方向发展。当前,政府进行制度改革,增强农民工维权能力、切实保障农民工的基本权益是必要的。     

美国金融危机与金融监管改革——基于新政治经济学的视角

金融监管的新政治经济学强调，作为一国政治制度行为主体的利益集团和政党在政策选择上具有十分重要的作用。本文分析了美国金融利益集团与左右翼政党的政策偏好对美国金融监管失灵与金融监管改革的影响。     

BEHAVIOR IN GROUP CONTESTS: A REVIEW OF EXPERIMENTAL RESEARCH

Group contests are ubiquitous. Some examples include warfare between countries, competition between political parties, team‐incentives within firms, and rent‐seeking. In order to succeed, members of the same group have incentives to cooperate with each other by expending effort. However, since effort is costly, each member also has an incentive to abstain from expending any effort and instead free ride on the efforts of other members. Contest theory predicts that the intensity of competition between groups and the amount of free riding within groups depend on the group size, sharing rule, group impact function, contest success function, and heterogeneity of players. We review experimental studies testing these theoretical predictions. Most studies find significant over‐expenditure of effort relative to the theory and significant heterogeneity of behavior within and between groups. Also, most studies find support for the comparative statics predictions of the theory (with the exception of the “group size paradox”). Finally, studies show that there are effective mechanisms that can promote within‐group cooperation and conflict resolution mechanisms that can de‐escalate and potentially eliminate between‐group conflict.
