基于双边视角的零售商运营研究

供应商的多样化和差异化,是零售平台的普遍特征。不同于源于供应商多样化的组间网络效应,源于差异化的供应商对顾客的边际组间网络效应是递减的,同时带来供应商间的负的竞争效应。研究发现,随差异化竞争的供应商数量增长,零售商对供应商的组间网络效应补贴下降,并向供应商收取源于差异化竞争的价格加成,限制差异化竞争的供应商数量。供应商间的差异化度越低,最优的差异化供应商数量越少。零售商在供应商多样化和差异化之间权衡选择的差异,形成零售商服务的差异化,有利于缓和零售商间的竞争。     

国际分散化投资与本土偏好行为——基于QDII对外投资基金的实证分析

本文运用2009年中国8家QDII基金境外组合的周收益历史数据,与基于全球29个股市指数的收益数据构建的国际投资分散化有效前沿进行比较,探讨QDII基金在境外投资过程中是否存在“本土偏好”。研究发现我国QDII基金与国际投资分散化有效边界都存在着不同程度的偏差,反映出较显著的本土偏好的投资行为。本土偏好减弱了国际分散化效果,降低了QDII基金的绩效。资本管制、交易成本和信息不对称是造成本土偏好的主要原因,因此放松资本管制,降低交易成本,降低信息获取成本,加快资本市场开放和合作能够使投资者更好地享受国际分散化投资带来的利益。

Can the Risks of the Kyoto Mechanisms be Reduced Through Portfolio Diversification? Evidence from the Swedish AIJ Program

Through Joint Implementationand the Clean Development Mechanism, reductionsof greenhouse gas emissions achieved abroad canbe credited to domestic firms. However, thetechnical, economic and political risksinvolved may prevent the private sector frominvesting in such projects. This paperdescribes three types of risks which emissionreduction projects are exposed to. Eleven pilotprojects carried out under the ActivitiesImplemented Jointly (AIJ) program and financedby Sweden are evaluated. Actual project costsare found to exceed projected costs in allcases. Annual emission reductions also deviatefrom their expected values and vary stronglyover time, supporting the hypothesis that suchprojects are risky business. The riskmanagement tool portfolio diversification isapplied to a sample of Swedish AIJ projects.The results indicate that diversification canreduce the risks of greenhouse gas mitigationprojects significantly. Thus, carbon funds area promising way of lowering the risks of theKyoto Mechanisms for private sector investors.     

地方财政压力与投资多样性——基于所得税分享改革的研究

利用企业所得税分享改革构建强度倍差模型,使用1997—2012年全国地级市数据,检验了地方财政压力对于投资多样性的影响及相关传导机制。结果表明,地方财政压力不利于投资多样性的提高;在财政压力下,地方容易形成偏向房地产行业的投资倾向。然而,不同地区地方财政压力对投资结构的影响存在异质性。经济发展水平较低的地区在财政压力下更容易降低投资多样性;而经济发展水平高的地区应对财政压力时,更倾向于通过多元化投资的方式做大税基、减轻财政压力。优化分税制结构、建立地方性税种能缓解地方财政压力,对于改变地方“房地产集中型”投资结构有一定的积极作用。

Capital Market Integration in the Middle East and North Africa

This paper studies capital market integration in Middle Eastern and North African (MENA) countries and its implications for international portfolio investment allocation. Starting with four cointegration methodologies, we significantly reject the hypothesis of a stable, long-run bivariate relationship between each of these markets and the European Monetary Union (EMU), the United States, and a regional benchmark. This indicates the existence of significant diversification opportunities for three categories of investors (EMU, world, and regional investors). A recursive analysis based on Barari (2004) suggests that recently, the MENA markets have started to move toward international financial integration. Investigating the effect of selected financial, economic, and political events on such a process, we extend the methodology and find that the markets react heterogeneously to the different categories of shocks. They should therefore not be treated as a bloc for global allocation purposes. Finally, after adjusting the integration levels by relative market capitalization, Israel and Turkey are the most promising markets in the region, followed by Egypt, Jordan, and Morocco. Tunisia and Lebanon seem to be lagging behind.     

央行数字人民币在“一带一路”区域化过程中的博弈分析

以央行数字人民币“一带一路”区域化为背景,构建中国与“一带一路”沿线国家、中国与沿线主要国际货币发行国的两两演化博弈模型,研究央行数字人民币在“一带一路”区域化进程中利益相关体的博弈过程及均衡结果,并通过情景模拟实验寻找博弈的最终演化均衡点。研究结果表明,尽管在短期内,央行数字人民币在“一带一路”区域化进程中会遭到来自沿线国家和沿线主要国际货币发行国的抵制,但是长期来看,央行数字人民币在”一带一路”区域化博弈中倾向于采取“推出”策略,且“一带一路”沿线国家倾向于采取“接受”策略,沿线主要国际货币发行国也倾向于采取“合作”策略,以此促进未来国际货币体系实现多元化发展。     

The international diversification-performance link in Spain: Does firm size really matter?

This study provides new insights into the link between international diversification and firm performance in a sample of large manufacturing firms and SMEs based in Spain for the 1994–2008 period. Specifically, the focus is on how the nature and shape of this relationship may vary over time with firm size. The results show the existence of a horizontal-S curve when the whole sample of firms is considered in the empirical analysis. However, major differences are found between SMEs and large firms, and even within the actual group of SMEs. Strong support is found in large firms for the existence of a horizontal-S curve. Within the group of SMEs, there are small firms with a linear and negative relationship, whereas medium-sized firms record a U-shaped form. These findings suggest that as the international diversification-performance link is size-dependent, future research should explicitly consider firm size in order to better understand the nature of this relationship.
