Relationship between oil,stock prices and exchange rates: A vine copula based GARCH method

In this paper, we apply a vine copula approach to investigate the dynamic relationship between energy, stock and currency markets. Dependence modeling using vine copulas offers a greater flexibility and permits the modeling of complex dependency patterns for high-dimensional distributions. Using a sample of more than 10 years of daily return observations of the WTI crude oil, the Dow Jones Industrial average stock index and the trade weighted US dollar index returns, we find evidence of a significant and symmetric relationship between these variables. Considering different sample periods show that the dynamic of the relationship between returns is not constant over time. Our results indicate also that the dependence structure is highly affected by the financial crisis and Great Recession, over 2007–2009. Finally, there is evidence to suggest that the application of the vine copula model improves the accuracy of VaR estimates, compared to traditional approaches.

Emerging Market Multinationals: Coopetition for Global Growth

Since the dramatic geopolitical shift toward liberalization in the last century, emerging‐market multinational enterprises (EMNEs) have become major players in global markets and continue to account for an increasing share of global foreign direct investment (FDI) flows. Given this trend, the questions of how and why EMNEs pursue FDI deserve greater attention. This article builds on recent work that uses resource dependence theory (RDT) to explain EMNE internationalization strategies. We propose that EMNEs, while often resource deficient relative to their developed‐market competitors and, therefore, more dependent on others in the external environment, are uniquely positioned to overcome these deficiencies over time through simultaneous cooperation and competition—coopetition—with their global rivals and host‐ and home‐country governments. These propositions contribute to the EMNE internationalization literature by more fully incorporating RDT into current theories of internationalization, highlighting the importance of managing dependencies over time to maximize global growth. © 2015 Wiley Periodicals, Inc.     

分整阶数半参数估计的有限样本性质研究

随着对经济和金融时间序列长记忆性的研究,分整阶数估计已成为当前理论研究的焦点问题。以对数周期图回归和局部Whittle方法为代表的半参数分整阶数估计方法在实践中得到广泛应用,但对这两类半参数估计方法的有限样本性质的比较则鲜有涉及,影响了在实践中对估计方法的选择。利用蒙特卡洛模拟方法,在不同数据产生的过程下,这两种半参数估计方法有限样本性质的研究结果表明：在ARFIMA(0, d, 0)过程下,LW类估计量具有较好的小样本性质;在平稳ARFIMA(1, d, 0)过程下,本文建议的QGPH估计量的有限样本性质要优于其他对数周期图估计量;在非平稳过程下,MGPH的偏差最小。     

治理理论视阈下交通运输社会管制制度分析

改革开放以来,我国交通运输业取得了令人瞩目的成就,但与此同时,交通安全、环境污染等问题也日益突出。在交通运输行业我们的社会管制制度存在着错位、越位和缺位等问题,为此本文运用了新制度经济学的制度变迁理论和公共治理理论对我国交通运输社会管制制度进行了分析探讨,认为传统的交通运输行业政府管理模式具有强大的惯性作用,决定了我国交通运输社会管制的制度变迁表现出比较明显的“路径依赖”性,正处于制度从均衡状态——不均衡状态——均衡状态中的不均衡状态即锁定状态,要实现交通运输社会管制制度的创新,我们必须要改革交通运输行业政府管理模式,由交通运输行业政府单极治理模式向社会、公众和政府的交通运输多元治理模式转变。     

中国A、B、H股间市场一体化进程研究——基于SKEWED-T-GJR-COPULA方法的实证检验

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。     

新疆棉花产业可持续发展的困境——以家庭为单位的经济学研究

棉花种植业在新疆区域经济发展中居于重要地位。日益突出的棉花种植、采收中的污染问题,水资源短缺与病虫害问题,棉花生产成本的上升、棉花收购价格风险的存在,以及棉花种植中形成的路径依赖,使新疆棉花生产的可持续发展面临严峻挑战。本文通过对2002年以来农户家庭棉花种植成本与收益变动趋势的分析,提出应加大棉花生产补贴力度,保证国家棉花生产安全;以生态农业生产促进新疆棉花产业的可持续发展。     

Criteria for the Stochastic Ordering of Random Sums,with Actuarial Applications

It is shown that vectors ( S M 1 , … , S Mn ) and ( S' M'1 , …, S' M'n ) of random sums of positive random variables are stochastically ordered by upper orthant dependence, lower orthant dependence, concordance or by the supermodular ordering whenever their corresponding random numbers of terms ( M 1 , … , M n ) and ( M' 1 , … , M' n ) are themselves ordered in this fashion. Actuarial applications of these results are given to different dependence structures for the collective risk model with several classes of business.     

The Capitalization of Public Services and Amenities into Land Prices — Empirical Evidence from German Communities

Applying the hedonic approach to land prices, this article investigates the capitalization of public services and pure amenities in a cross section of German communities. Possible spillover effects from neighboring municipalities are explicitly included in the analysis and prove to be of considerable importance. Estimates of the impacts of local attributes on land prices are obtained taking into account the spatial structure among unobserved variables. The results confirm that differences in land prices are largely attributable to local conditions and policies. This implies a significant degree of mobility as well as high estimation of local attributes on the part of German households.     

Perceptual difference of dependence and its impact on conflict in marketing channels in China: An empirical study with two-sided data

Although many firms have adopted the relational exchange or relationship marketing philosophy for developing long-term inter-firm relationships in marketing channels, the issues pertaining to channel conflict still deserve further investigation. The purpose of this paper is to examine the possible impact of perceptual difference of dependence between members in channel dyads on perceived channel conflict. By analyzing paired data collected from both sides of supplier-retailer dyads in China, we test two hypotheses about perceptual difference of dependence and its impact on conflict. We found that there was considerable perceptual difference of dependence between both sides of the dyads, and that the perceptual difference of dependence asymmetry between the two was positively associated with channel conflict perceived by the supplier side. Both researchers and practitioners should be aware of such differences when confronted with channel conflict issues, especially in international channel settings.
