Financial leverage and market volatility with diverse beliefs

We study a general equilibrium model of asset trading with financial leverage, where the investors can engage in speculative trading with diverse beliefs about the asset??s fundamental value. We show that an increase in the leverage ratio causes the stock price to rise in the current period through a ??leverage effect??, and will result in more borrowing and more stock purchase that pumps the stock price higher in the subsequent period, known as the ??pyramiding effect??. There can also be a ??depyramiding effect?? when the price falls because lenders issue margin calls and force stock sales, contributing to further stock price plummeting. Price changes from depyramiding effect, however, may not take effect when margin calls are not triggered. We demonstrate that, under certain conditions, decreasing leverage ratios leads to lower stock price volatility, measured by the variation of prices caused by an exogenous shock, when the shock is unanticipated. The influences of dispersion of beliefs and available investment funds on the relation between financial leverage and market volatility are also examined. When the shock is anticipated, we demonstrate that reducing leverage ratios may not lower stock price volatility, which poses an important challenge to future studies on this issue.     

全要素生产率、人民币汇率与中国贸易收支——基于跨期最优选择理论的实证研究

文章首先以跨期最优分析框架为基础建立以中国贸易收支为研究对象的理论模型,然后基于中国1999-2009年省际面板数据,运用面板FMOLS估计方法,从全国和地区两个层面对中国全要素生产率、人民币实际汇率与中国贸易收支的关系展开实证分析。研究表明,中国贸易部门内资企业和外资企业的全要素生产率提升均对中国实际贸易余额增长产生了正面影响,其中东部地区的促进作用最为强劲;中国非贸易部门全要素生产率与其实际贸易余额负相关,其中东部和中部地区非贸易部门全要素生产率提升会显著减少该地区的实际贸易差额;人民币实际有效汇率提升对中国实际贸易收支具有显著的负面影响,并按照东部、中部和西部地区依次加重。根据上述分析结果,文章提出了调节中国贸易收支的相关政策建议。     

逆向选择视角下电子商务市场与传统市场间关系研究

电子商务的出现和快速成长反映出它对信息环境具有支配性的优点,这本身就意味着电子商务市场可能成为传统市场的替代。然而,逆向选择问题明显限制了这种替代效应程度。文章基于经典逆向选择模型,通过所构造的双市场(传统市场与电子商务市场)逆向选择模型,证明伴随着质量不确定性而诱发的逆向选择问题,在电子市场和传统市场之间会产生市场的不均衡,从而导致渠道冲突。文章试图揭示传统市场和电子商务市场并存的学理根源,得出两市场间市场细分的条件,对两市场间的渠道冲突提出新的解释,并据此提出了逆向选择下企业营销的策略建议。     

不确定环境下的物流服务供应链风险分析

在对物流服务供应链风险进行定义和深入分析物流服务供应链不确定环境的基础上,通过构建物流服务供应链的风险分类模型,理清其联盟生命周期各阶段的风险类型,并提出相应的风险防范策略;针对不确定环境中尤为突出的分包商组合风险问题,设计一种分包商绩效与风险矩阵,利用权变理论进行了合理的剖析,从而对物流服务供应链风险有了一个全面而系统的认识,为有效防范该风险奠定基础。     

Evaluating green supply chain management among Chinese manufacturers from the ecological modernization perspective

Green supply chain management (GSCM) has become an emergent ecological modernization tool amongst Chinese manufacturers to balance environmental performance with productivity and business performance gains. Ecological modernization at the society level is influenced by restructuring policies and regulations. Some of these policies and regulations in China are focusing on enhancing energy savings and pollution reduction (ESPR). Based on a survey of 376 responses, we investigate whether different Chinese manufacturer clusters varying in their extent of implementing GSCM exist from this ecological modernization perspective. We also examine if Chinese manufacturers’ awareness of domestic and international environmental ESPR-oriented compliance is related to GSCM implementation and whether a mediating effect of regulatory pressure plays a significant role. The results highlight the varying pace of Chinese manufacturers to ecologically modernize with GSCM practices and the significance of regulatory pressure to diffuse the practices adoption by Chinese manufacturing industry. Implications of this research go beyond the manufacturers investigated in this study where similar occurrence of these relationships may exist in other regions.

当代传媒业绩效考评弊端与对策研究

中国传媒业绩效考评缺乏政策评价体系,绩效考评机制滞后,还存在重"量"轻"质"、重"奖励"轻"发展"等不良倾向。要清除诸多弊病,首要的是制订符合传媒市场需要的科学的评价标准,在此基础上完善绩效考评体系,注意绩效考评体系内外的联系,以"能力"为本位;变职称工资管理为绩效工资管理实行年终绩效考核,推行末位淘汰制等。     

地产低迷与货币超发的市场性政策矛盾

中国房地产行业近些年来的高位运行,与在分税制背景下地方政府对土地财政的依赖以及政府与房地产商的利益合谋有关,即地方政府依靠土地开发和土地转让获得预算外的财政收入,同时也使地方政府GDP政绩大幅增长。目前的楼市惨淡还只是对这几年房价涨幅的回落调整,一些开发商的随行就市心态使作为资源调配的价格策略变得愈加谨慎。值得注意的是,中国的房地产市场与世界宏观经济形势之间并没有必然的联系。
