Approximation of the Bivariate Renewal Function

Recently, Kambo and his co-researchers (2012) proposed a method of approximation for evaluating the one-dimensional renewal function based on the first three moments. Their method is simple and elegant, which gives exact values for well-known distributions. In this article, we propose an analogous method for the evaluation of bivariate renewal function based on the first two moments of the variables and their joint moment. The proposed method yields exact results for certain widely used bivariate distributions like bivariate exponential distribution, bivariate Weibull distributions, and bivariate Pareto distributions. An illustrative example in the form of a two-dimensional warranty problem is considered and comparisons of our method are made with the results of other models.     

美国对外贸易政策的历史考察

自北美独立战争结束以来,美国的对外贸易政策大致经历了五个阶段.其中保护主义始终贯穿于美国的对外贸易政策之中.虽然自由贸易有时偶占上风,但这种所谓的自由贸易是有条件的、相对的,是美国打着"互惠、公平、非歧视"的幌子,欲抢占别国市场.为了实现大资产阶级利益的最大化,美国总是将贸易保护政策奉为圭臬,这一政策才是无条件的、绝对的.     

自由心证的解构与建构

自由心证制度是对法定证据制度的否定,相对于法定证据制度而言,它能够充分调动裁判者司法认识的主动性和增加司法认识过程的能动性,有利于案件事实的发现与司法正义的实现,本文从我国借鉴自由心证制度的概念及其原理开始论述,尝试对自由心证进行全新的建构。     

恩格斯对“自由人联合体”思想形成的独特贡献

“自由人联合体”思想是《共产党宣言》中的重要思想。恩格斯对这一思想的形成有着独特性的贡献。依据经典文本,恩格斯的独特性贡献主要体现在如下四方面:从社会秩序出发揭示资产阶级社会的无序性事实,阐明构建“自由人联合体”之必要性;从利益出发论证共产主义社会所应遵循的共同利益原则,阐明“自由人联合体”之优越性;从人性与自由关系出发阐述资产阶级社会中人性丧失的状况,阐明“自由人联合体”之价值性;从社会实践出发提出消灭资本主义私有制、推翻资产阶级统治、实现共产主义的革命道路,阐明“自由人联合体”之革命性。     

品牌资产及其测量中的概念解析

品牌资产(品牌权益)是近年来营销领域中研究的热点问题,然而对于其基本概念的曲解却阻碍了对这个重要问题的进一步研究。本文针对品牌资产涉及的几个概念(品牌资产、品牌权益、品牌价值)及其相互关系加以解释,并将主要的品牌资产的测量方法进行分类,目的是澄清人们对于品牌资产基本概念的模糊认识,为进一步深入研究指明方向。     

品牌延伸:资产价值转移与理论模型创建

本文通过对品牌延伸(Brand Extension)的研究综述和实证研究,提出决定品牌延伸的三大因子,并在此基础上构成品牌资产价值(Brand Asset Value),进而研究其在品牌延伸过程中的价值转移,从而构成了评估品牌延伸成败的标准,最终将各种因子和评估标准进行整合,提出了品牌延伸的理论模型。     

Power and dependence perspectives on outsourcing decisions

Since the 1980s outsourcing has been a major topic in both economic and management literature. Economic literature tends to focus on the transaction cost perspective. In management literature the core competence approach prevails. An emerging alternative view on outsourcing is the power and dependence perspective. Aspects of power and dependence become visible in four case studies involving the maintenance of capital assets. In each instance both the buyer and supplier sides of the dyad are examined. The paper concludes with managerial implications and research opportunities.

世界各地的华侨华人经济联系建构了世界华商网络 ,并以此融入世界体系 ,形成了整个“中华经济圈” ;而包括粤港澳台闽桂琼在内的“华南经济圈”则构筑了“中华经济圈”的圆心 ,并维系其经济增长 (“圆周半径”)的动态平衡。“华南经济圈”由闽台经济区、珠江三角洲经济区、环北部湾沿岸经济区和环南中国海经济区所构成 ,它参与中国———东盟自由贸易区的优势主要在于地缘经济优势、特区经济优势和会展经济优势     

No‐Bubble Condition: Model‐Free Tests in Housing Markets

We test for the existence of housing bubbles associated with a failure of the transversality condition that requires the present value of payments occurring infinitely far in the future to be zero. The most prominent such bubble is the classic rational bubble. We study housing markets in the United Kingdom and Singapore, where residential property ownership takes the form of either leaseholds or freeholds. Leaseholds are finite‐maturity, pre‐paid, and tradeable ownership contracts with maturities often exceeding 700 years. Freeholds are infinite‐maturity ownership contracts. The price difference between leaseholds with extremely‐long maturities and freeholds reflects the present value of a claim to the freehold after leasehold expiry, and is thus a direct empirical measure of the transversality condition. We estimate this price difference, and find no evidence of failures of the transversality condition in housing markets in the U.K. and Singapore, even during periods when a sizable bubble was regularly thought to be present.     

中韩FTA背景下工业制成品产业内贸易发展探析

中韩FTA作为中国目前为止签订的贸易额最大、涉及范围最广的贸易协定,其正式签署使得两国之间的经济贸易有了新的发展,在促进两国战略合作伙伴关系的同时,更有助于中国参与全球的经济融合。在中韩两国贸易近几年的发展中,产业内贸易所占比例不断增长,工业制成品占两国双边贸易额的比重也在不断增加。因此,在中韩FTA背景下研究两国工业制成品产业内贸易将会对中国的经济起到极大的促进作用,同时为两国的协调发展打下基础。
