伴随着国际资金的频繁流动,东亚金融市场成为国际证券投资的主要地区。东亚各国和地区为了使其股票市场健康稳定发展,采取了一系列措施增强其区域内股票市场的一体化程度。本文通过Johansen协整,方差分解等方法,分析了当前东亚股票市场的股票指数与两大国际股票市场(美国和日本)股票指数的趋同性,以此为基础讨论东亚股票市场的全球一体化程度与区域一体化程度。本文研究发现,东亚股票市场的一体化程度不高,但其全球化程度高于其区域化程度。 相似文献

本文通过构建动态Copula方法,以相依性作为股市间一体化整合指标,考察了1994年至2009年A、B、H股间的一体化进程,发现A股间的一体化基本达到完全整合,两B股间也达到了很高的水平,这两组市场的整合主要在1995年到1997年完成的。A股与B股间一体化程度也较高,其中亚洲金融危机和2001年2月B股改革推动了两市场的整合。而A、B股与H股间的一体化程度相对较低,它们间的整合开始较晚但仍在进行,其中股权分置改革和QDII的实施具有较大的推动作用。另外,中国金融市场如汇率、银行等的改革可能也提高了A、B股与H股的整合速度。 相似文献

We propose two characteristics of beliefs and study their role in shaping the set of rationalizable strategy profiles in games with incomplete information. The first characteristic, type-sensitivity, is related to how informative a player thinks his type is. The second characteristic, optimism, is related to how “favorable” a player expects the outcome of the game to be. The paper has two main results: the first result provides an upper bound on the size of the set of rationalizable strategy profiles; the second gives a lower bound on the change of location of this set. These bounds are explicit expressions that involve type-sensitivity, optimism, and payoff characteristics. Our results generalize and clarify the well-known uniqueness result of global games (Carlsson and van Damme, 1993). They also imply new uniqueness results and allow us to study rationalizability in new environments. We provide applications to supermodular mechanism design (Mathevet, 2010b) and information processing errors. 相似文献

Abstract With the growth of e-commerce has come the need for businesses to provide protection of personal, private data collected from internet users and consumers. The United States has favored a policy of industry self-regulation, while the European Union (EU) has responded to its consumer demands for privacy protection regulations and enforcement. Faced with the critical need for a middle ground, the US has proposed “Safe Harbor Privacy Principles” as a means of compromise with the EU. This article explores the market context of the Safe Harbor Principles, the European reaction, and the probable impact on businesses. 相似文献

This paper reviews 726 academic research studies covering logistics and supply chain management (L'SCM) applications within a global context. Articles are analyzed according to their publication year and outlet, common themes, and countries or regions investigated. The sample was drawn from the ABI/INFORM Global database, which includes almost 1,800 journal titles. The review offers a starting point for researchers, graduate students, faculty members or practitioners examining international L'SCM applications. The article also draws attention to the wide array of global L'SCM studies conducted, their settings and viewpoints. Additionally, this paper highlights some of the most interesting works and draws attention to lesser‐researched countries and regions of the world. The overview also provides an introduction for practitioners and managers to what academic research has covered in the area of global L'SCM. Practitioners can use this review as a starting point for the identification of relevant and useful references for their particular task. 相似文献

The objective of this paper is to develop conditions for global multivariate comparative risk aversion in the presence of uninsurable, or background, risks, and thus generalize Kihlstrom and Mirman [1974] and Karni [1979,1989]. We analyze von Neumann-Morgenstern (VNM) utility functionsas well as smooth preference functionals which are nonlinear in distribution but locally linear in probabilities. In each case we provide an economic application which illustrates how our theorems can be used. We analyze a risk sharing, a portfolio choice, and a labor supply problem for VNM utility functions, and the optimal allocation of effort to risky technologies in the presence of a random supply (or quality) of a public good for nonlinear preference functionals. We consider thecase where the random variables are mean-independent as well as the case where they are independent. In the labor supply application for VNM utility functions, we show that if the two risks are independent, the comparative statics effect of greater risk aversion on labor supply in the presence of a background non-wage income risk is determined by a monotonic relationship between labor supply and the wage rate under certainty. That is, we extend the applicability of the Diamond-Stiglitz [1974]-Kihlstrom-Mirman [1974]single-crossing property to the case where an independent background risk is present. 相似文献

We consider the multistage hybrid flowshop scheduling problem, in which each stage consists of parallel identical machines. The problem is to determine a schedule that minimizes the makespan for a given set of jobs over a finite planning horizon. Since this problem class is NP-hard in the strong sense, there seems to be no escape from appealing to heuristic procedures to achieve near-optimal solutions to real life problems. First, a series of new global lower bounds to be used to estimate the minimum makespan are derived. Then, two new metaheuristic algorithms first sequence and then allocate jobs to machines based on a particular partition of the shop. The optimization procedure is based on simulated annealing and the variable-depth search. Computational experiments show the efficiency of the proposed procedures. 相似文献

Global apparel production and sweatshop labour: can raising retail prices finance living wages? 总被引:1,自引:0,他引:1
This paper provides some empirical evidence on issues raisedby the global anti-sweatshop movement. We first consider therelationship between wage and employment growth, finding noconsistent trade-off between them. We then measure the shareof labour costs in the production of garments in the US andMexico. We find that the retail price increases necessary toabsorb the costs of raising wages substantially are small, wellwithin the range of price increases that polls suggest US consumersare willing to pay. We close by considering some implicationsof these results. 相似文献
