当前我国城镇廉租房制度创新模式探索

城镇廉租房制度是最经济、最公平、最能满足城市低收入家庭住房需求的制度,但其建设的现状和进展并不令人乐观,主要体现在政府职能仍然缺位、资金来源渠道狭窄、保障对象衔接错位等方面。文章在借鉴发达国家廉租房制度建设经验和教训的基础上,提出了未来我国城镇廉租房制度建设的“实施廉租房供应方案无缝化链接、赋予廉租房保障措施法律化依据、创新廉租房保障资金多元化渠道”等创新方案,这些方案将对构建我国未来城镇廉租房制度模式具有重要参考意义和价值。     

关系型融资是解决中小企业融资难的有效途径

为避免信息不对称带来的道德风险和逆向选择,商业银行实行信贷配给,中小企业难以从银行获得贷款。关系型融资的出现,使银行能完全掌握中小企业的内部信息,获得长期租金收入。关系型融资能减少代理成本,降低交易费用,救助陷入财务困境的企业。关系型融资是中小企业和银行“双赢”的融资模式。关系型融资要求中小企业的治理结构创新、商业银行制度创新、中小企业信用体系创新。

中国艺术品贸易发展现状及对策研究

改革开放以来,中国艺术品市场作为一个较大的文化艺术和经济体系愈渐壮大,已经占据全球艺术品三大市场之一的地位.同为全球艺术品三大市场成员的美国与英国的艺术品的市场体系已相当成熟,然而中国的艺术品市场体系并不完善,贸易市场仍存在一些不合理的现象.中国艺术品贸易规模存在下降趋势,国际贸易份额较低,虽然艺术金融及其产业规模在不断上升,但是与英美相比,金融化程度较低,且在国际艺术品市场中的贸易竞争力不足.此外,中国艺术品市场存在诚信不足、评估鉴定体系不合理、专业人才缺失且进口关税较高等问题.中国艺术品要想继续发展强大,需从艺术品市场观念、艺术品市场环境以及中国化市场道路等方面做出改变及提升.     

对中国农村金融制度变迁的制约因素与基本特征的思考

农村金融制度的变迁主要受初始条件、经济体制、发展战略及利益集团的要求等因素的制约,其基本特征表现为:因为金融抑制的存在,农村金融制度变迁是一种非农村经济主体需求导向性的机制演进,由政府主导自上而下强制性供给;自上而下的强制性农村金融制度变迁与自下而上的诱致性农村经济制度变迁路径相背离;农村规范的外生金融与不规范的内生金融的冲突贯穿于整个农村金融制度变迁的全过程。考察农村金融制度的变迁过程,得出:农村金融制度变迁滞后于农村经济制度的变迁;农村金融制度结构与农村经济制度结构不对称;农村金融与农村经济的制度变迁存在相互制约的关系。     

Agglomeration spillovers and wage and housing cost gradients across the urban hierarchy

The tyranny of distance in terms of its effect on median earnings and housing costs is examined for rural and urban U.S. counties. First, we develop a series of distance metrics for an area's remoteness from multiple tiers of the urban hierarchy. Second, we consider geographical access of buyers and sellers through market potential measures typical of those used in empirical studies of the New Economic Geography. We estimate penalties of about 5 to 9% for median earnings and 12 to 17% for housing costs for area remoteness from the combined tiers of the urban hierarchy. Differences in market potential also influence factor prices, but these effects generally are smaller than those produced by urban hierarchy distances. Thus, it appears that empirical tests of New Economic Geography models need to consider sources of agglomeration spillovers beyond aggregate market potential.     

经济下行压力加大对农业投入的影响研究

由于经济下行压力不断加大,我国农业投入面临增长乏力的境况.我国财政农业存在支出不足、农业信贷资金投放不足、农户投入不足等问题,为此应采取强化财政对农业的投入、鼓励金融机构增加农业信贷投入、激励农户自愿加大农业投入等措施,确保我国农业投入持续稳定增长.     

一种改进的扩展窗喷泉码不等差错保护编码算法

针对传统不等差错保护（Unequal Error Protection,UEP）算法在加性高斯白噪声信道中存在误码平台的问题,提出了一种改进的扩展窗喷泉码（Expanding Window Fountain,EWF）编码算法。通过为不同重要等级数据加窗的方式,使得重要等级较高的信息节点能够以更高的概率连接至更多的校验节点。在编码过程中分开记录不同窗内信息节点的度数值,并优化校验节点选取信息节点的方式,使得度数值相对较小的信息节点始终能被优先选取,从而提高了每个窗内信息节点的平均度数值,为各重要等级的数据提供了额外的增益。仿真结果表明,改进的EWF算法可将不同等级数据的误码平台降低1~2个数量级,且数据的等级越高,保护性能越强。     

Certified public accountants: Ethical perception skills and attitudes on ethics education

This study investigated the proficiency of CPAs in recognizing and evaluating ethical and unethical situations. In addition, CPAs provided attitudes on ethics education. Respondents were asked to evaluate the ethical acceptability of CPA behavior as presented in six vignettes involving a variety of ethical dilemmas from questions of conflict of interest to questions of personal honor. The results tend to signify that CPAs can, to a degree, distinguish ethical and unethical behaviors. It appears that ethical behaviors and very specific unethical behaviors were more easily identified by practitioners. This may reveal uncertainty and apprehension as to exactly what constitutes unethical behavior since, in many circumstances, this resolution is made on a case-specific basis rather that via a universal rule. In addition, it is interesting to note that CPAs tend to picture themselves as more ethically-oriented than their peers.With respect to ethics education, the CPAs indicated that instruction in ethical concepts and literacy was important and should definitely be embodied in the accounting curriculum as well as at all educational levels. However, the CPAs were remarkably uncertain and ambivalent as to the qualifications of university faculty to provide this instruction and guidance.Suzanne Pinac Ward, CPA, is an Associate Professor of Accounting at the University of Southwestern Louisiana in Lafayette, LA 70504.

沪深300指数的ARCH效应

股价指数的收益率序列具有时变波动性、厚尾特征、波动性群集等特点,传统的计量分析无法刻画这些特点。通过对即将推出的股指期货的标的指数-沪深300指数的收益率序列进行AR-CH效应分析．采用ARCH模型及其扩展形式对沪深300指数的波动性进行实证分析,结果表明沪深300指数的收益率序列是有偏的,并具有尖峰厚尾的特点。同时也具有波动的群集性和不对称性的特点。
