中国家电市场营销渠道变革与家电制造企业的渠道关系选择

随着大型家电连锁零售业态的迅速成长,中国家电市场营销渠道正处于冲突多发、重组加剧的演变阶段.处于变革环境中的家电制造企业如何调整自己的渠道关系,取决于外部环境的不确定性、中间商对下游渠道创造增加值的能力和制造商的可替代性三个变量的不同组合.本文基于上述变量,在Kim&Frazier对渠道关系类型研究的基础上,构建了我国家电市场的渠道关系模型,据此阐述不同品牌影响力的家电制造企业在不同层级市场的渠道关系选择.     

做市商制度对我国新三板市场的影响

场外交易市场建设初期,做市商制度在各国家及地区得到普遍应用。随着市场规模的扩大,交易制度逐步演变为混合性做市商制度。2014年我国新三板市场引入做市商制度,通过对市场整体以及协议转让、做市转让两类股票样本进行比较,文章认为在政策推动、市场主体积极参与等因素作用下,新三板市场整体规模、流动性均得到快速提高,做市商制度在流动性改善、价值发现等方面具有重要作用,挂牌公司具有较强的差异性对分层管理提出了现实需求。提高流动性仍然是新三板市场的重要任务之一,文章认为需要从制度、需求、供给、监管四个方面进行采取积极措施。     

Bad news does not always travel fast: evidence from Chapter 11 bankruptcy filings

This paper examines the stock price performances of 275 non‐financial, non‐utility U.S. industrial firms that continue trading on the main exchanges after filing for Chapter 11 bankruptcy between 1 October 1979 and 17 October 2005. This paper identifies a negative and statistically significant post‐bankruptcy drift that lasts for at least 6 months. This finding adds to the literature showing that the market is unable to process bad public news events in a timely manner. Further analysis suggests that the theoretical model proposed by Hong and Stein (1999) can be used to help explain this market‐pricing anomaly.     

人寿保险行业市场结构及影响因素研究

准入退出壁垒、市场集中度、规模经济和范围经济以及产品差异化等是影响人寿保险业市场结构的主要因素。中国保险市场准入、退出的行政性政策壁垒较高,市场集中度较高,属于寡占 III 型市场结构;寿险业保费规模、保险密度、保险深度、保险资产总额占 GDP 的比重、保险资产总额占整个金融资产的比重较低;寿险产品同质化现象较严重。鉴此,应降低市场进入壁垒,建立市场退出机制,达到优化市场结构,提高资源配置效率目的。     

极端死亡率债券的运行机制与定价模型

极端死亡率债券是票息或面值与极端死亡概率相关的债券,能够将寿险公司所面临的极端死亡率风险转移到资本市场。本文阐述了极端死亡率债券的市场发展,包括发行规模、触发机制、债券期限、债券分层、债券评级等,分析了以 Tartan 债券为代表的本金赔付累积型极端死亡率债券的运行机制,并给出了考虑极端死亡率风险的跳跃性特征下的本金赔付累积型极端死亡率债券 Wang 转换定价的解析式。     

A comparison of buy‐side and sell‐side analysts

There is very little research on the topic of buy-side analyst performance, and that which does exist yields mixed results. We use a large sample from both the buy-side and the sell-side and report several new results. First, while the contemporaneous returns to portfolios based on sell-side recommendations are positive, the returns for buy-side analysts, proxied by changes in institutional holdings, are negative. Second, the buy-side analysts' underperformance is accentuated when they trade against sell-side analysts' recommendations. Third, abnormal returns positively relate to both the portfolio size and the portfolio turnover of buy-side analysts' institutions, suggesting that large institutions employ superior analysts and that superior analysts frequently change their recommendations. Abnormal returns are also positively related to buy-side portfolios with stocks that have higher analyst coverage, greater institutional holding, and lower earnings forecast dispersion. Fourth, there is substantial persistence in buy-side performance, but even the top decile performs poorly. These findings suggest that sell-side analysts still outperform buy-side analysts despite the severe conflicts of interest documented in the literature.     

Position limit for the CSI 300 stock index futures market

The aim of this study was to find the optimal position limit for the Chinese stock index (CSI) 300 futures market. A low position limit helps to prevent price manipulations in the spot market, and thus keeps the magnitude of instantaneous price changes within the tolerance range of policymakers. However, setting a position limit that is too low may also have negative effects on market quality. We propose an artificial limit order market with heterogeneous interacting agents to examine the impact of different levels of position limits on market quality, measured as liquidity, return volatility, efficiency of information dissemination, and trading welfare. The simulation model is based on realistic trading mechanisms, investor structure, and order submission behavior observed in the CSI 300 futures market.Our results show that on the basis of the liquidity status in September 2010, raising the position limit from 100 to 300 could significantly improve market quality and at the same time keep the maximum absolute price change per 5 s below the 2% tolerance level. However, the improvement becomes only marginal if the position limit is further increased beyond 300. Therefore, we believe that raising the position limit to a moderate level can enhance the functionality of the CSI 300 futures market, which should benefit the development of the Chinese financial system.     

要素市场扭曲、区域差异与R&D投入

本文利用要素市场扭曲指数及中国高技术产业1997～2009年省际面板数据,考察了要素市场扭曲对R&D投入的影响及区域差异。结果表明,要素市场扭曲对R&D资本投入和R&D人力投入有着不同的影响,抑制了R&D资本投入增长,促进了R&D人力投入;而且其对两者的影响都存在着显著的区域差异。在此基础上,运用门槛检验方法对这种区域差异的影响因素进行了探讨,研究发现,在区域经济发展水平、人力资本水平、财政收入、产权结构和对外开放程度等因素的不同门槛值区间,要素市场扭曲对高技术产业R&D投入的影响程度和方向都存在着明显的差异。
