中国债券市场信用利差的实证研究——基于含跳跃过程的单因子信用利差模型的估计

本文在CKLS单因子利率模型中加入跳跃过程,并对银行间固定利率AA级3年期企业债信用利差通过极大似然估计法进行了实证分析。结果表明,跳跃模型可以较好地拟合AA3品种企业债信用利差的运行过程,且该品种企业债信用利差存在均值回复特征,但不存在水平效应与波动聚类特征,信用利差过程的跳跃性不明显。

Sustainable product disposal: Consumer redistributing behaviors versus hoarding and throwing away

Business strategies involving sustainable product disposal have focused mostly on technical aspects but neglected to adequately incorporate the nature of consumers' behavior. The current study addresses this void. We study consumer product disposal behavior and subsequently offer insights to businesses on how to incorporate consumer input into their strategic decision making in the light of opportunities to mitigate environmental impacts. Consumers' redistributing of unwanted but still useful products to others by reselling, passing along, or donating, rather than hoarding or throwing away, contributes to product lifetime extension and waste management. We study factors influencing product redistribution and explore profile of consumers who engage in various disposal behaviors. Findings from two online surveys, on mobile phones and sunglasses, reveal that specific waste attitudes, that is, waste minimization and waste aversion, rather than general environmental concern, are key determinants of product redistribution choice. Product cost is positively related to reselling and giving behaviors. Furthermore, product quality and product self-image congruency significantly reduce the odds of throwing away. The method of product redistribution is also influenced by consumers' demographic characteristics including age, education level, and income. This paper advances extant literature on product disposal from the perspective of the consumer and provides input into development of business strategies that incorporate consumers' sustainable disposal behaviors. We also offer input to policy makers on how to curb or delay waste and pollution.     

“十四五”时期强化就业优先政策体系研究

就业优先政策是新时代坚持就业优先战略和积极就业政策的具体体现。就业优先政策体系是一整套的就业政策体系,手段多样,受益对象广泛。当前,就业优先政策存在政策安排与就业总目标不协调、三分割制约政策整体效能释放、金融政策凸显总量和结构矛盾、现有政策滞后于就业灵活趋势及失业保险政策运用不充分等问题。为最大程度释放政策体系效能,尽快完善政策体系,实现精准施策,重点施策,稳定施策,建议调整财政支出政策,优化就业支出结构,按照居住地确定就业优先政策扶持对象,完善就业财政补贴政策,畅通传导机制,强化金融政策促就业效能,加强政策对灵活就业的支持、规范和保障,改进失业保险补贴政策,扩大资金受益面。     

中国工业制成品出口竞争力的实证分析

实证分析表明,改革开放以来中国工业制成品的出口总量迅速扩张,出口结构和竞争力不断优化和提高,在世界制成品贸易中的地位逐步上升。一方面,工业制成品出口高速增长是中国工业化和对外开放进程加快、国内制造业技术进步和结构调整的结果;另一方面,工业制成品出口也带动了中国制造业国际分工地位和竞争力的提高,二者相互促进、共同发展。加入WTO后,中国对外开放力度加大,为全面提升制造业的国际竞争力、扩大制成品出口带来了新的契机。     

论UCP600的审单标准——兼评UCP600第14条

信用证的审单标准是一个在实际操作中很棘手的问题.关于信用证的审单标准与原则有不同的学说和主张,但严格相符原则是各国普遍采用的做法,它有利于信用证交易的确定性,提高信用证交易的效率,但也具有不可避免的缺点.新颁布的UCP600对审单标准作了一些调整,原来的严格相符原则有所放松,朝着实质相符原则迈进,这些变化势必影响贸易各方.     

合作社:从资本主义脱颖而出的生产模式

作为一种自治团体,合作社已有160余年的历史。在中国的社会主义建设和经济体制改革中,合作社始终并还将继续发挥无可替代的重要作用。然而,合作社在中国的发展还面临各种障碍的约束。重温马克思有关合作社的论述,可以使我们更加深刻地认识合作社这种生产形式的优越性,从而更加主动地在经济建设中运用这一生产形式。

Welfare effects of network neutrality in mobile Internet market

ABSTRACT

The network neutrality can enhance the profitability of content providers but reduce carrier platforms’ profits and consumer surplus. What is more, network neutrality can improve the total social welfare level when the external utility of mobile phone users to content providers is greater than that of content providers to those users. In addition, it is also found that both profitability of content providers and pricing power of carrier platforms for mobile phone users are directly proportional to the basic utility that carriers themselves can provide.     

登记机构不审核申请人的婚姻状况，依申请登记为申请人所有

在房地产登记和房地产登记行政案件应诉实践中,关于夫妻房产登记问题,有不少人认为,登记机构应审核申请人的婚姻状况,以确定房产共有与否。但在笔者看来,对于夫妻房产的登记,登记机构不审核申请人的婚姻状况,依申请登记为申请人所有,并且登记后再转让也不必征得未被登记为产权人的配偶（隐性共有人）的同意。
