参股保险业与企业流动性风险管理:基于货币政策变更背景

现阶段宏观经济政策不断变更给企业经营带来诸多不确定性,从而增加了流动性风险,而通过参股保险公司所建立的产融结合平台能使企业降低制度调整的风险成本。我们对此进行了实证分析,以2006年～2010年上市公司季度数据为样本,利用倾向概率配对模型控制样本内生性问题后实证检验发现:参股保险公司的上市公司日常现金持有水平和调整水平较未参股公司低,且在面对从紧货币政策时,这种流动性风险管理的提升效果更加突出。结论显示,上市公司与保险公司建立产融结合平台具有财务协同效应,部分抵消了货币政策变更不确定性的冲击。这一研究对于企业产融结合实践策略部署有着重要的现实意义,对保险行业引导产融结合趋势也有较强的实践参考价值。     

我国股票市场是否存在资产被迫拍卖——基于开放式股票型基金的研究

对于资产被迫拍卖行为的研究具有重要意义,因为它为我们提供了一个新的视角探讨流动性约束对股票价格变动的影响。本文基于Coval和Stafford(2007)的研究方法对我国股票市场中资产被迫拍卖行为的存在性进行了研究,结果表明在我国股票市场中存在着资产被迫拍卖行为,但其具体表现特征与Coval和Stafford(2007)的研究结论存在着一定的差异,而导致该差异出现的原因与我国开放式基金市场中存在着赎回困惑现象有关。     

结构性通货膨胀的一个基本理论分析框架——基于状态空间时变参数模型的实证

以实体经济的部门瓶颈制约模型、货币视角的资产市场均衡模型为基础构建了一个结构性通货膨胀理论分析框架,并利用状态空间时变参数模型计量方法进行了实证检验。结果显示,农业部门瓶颈制约明显,产品供给弹性低,当需求短期内增加,农业劳动力、农产品价格上涨的结构性通货膨胀特征明显;同时,当货币流动性出现过剩,充足的流动性会将结构性通货膨胀推向更高水平,国内货币流动性、外汇储备则起到推波助澜的作用。     

流动性、合理流动水平与宏观管理的现实情境

在宏观调控层面判断流动性是否合理的标准,主要取决于流动性是否能保证通货膨胀维系在合理水平,并以此促进经济增长。由于经济发展的阶段不同,发达国家与发展中国家实际通胀率以及可容忍的通胀率可能都存在差异。流动性的波动较大,甚至受心理预期、投机等多种因素影响,往往难以预测。从近年来的现实来看,我国的流动性管理和宏观调控具有鲜明的中国特色,其调控思路与我国的现实国情基本相符。我国逐步试错的渐进性宏观调控方法具有较强的现实科学性和中国式哲学的逻辑性,甚至在传统货币政策理论方面,也作出了创新性的贡献。     

股票分拆与并股对市场流动性的影响 --来自于香港股票市场的证据

股票分拆与并股这类事件一直迷惑着学者和实际工作者.本文利用香港股票市场的数据,研究分拆与并股对股票的市场流动性的影响.而且还研究了这类事件对股票在市场中的交易活动性的影响,以便将交易活动性与市场流动性联系起来,通过交易活动性的变化来解释造成流动性变化的根本原因.结果表明股票在分拆后流动性增强,而且是由小额交易的活跃引起的;股票在并股后流动性减弱,是由小额交易与大额交易的不活跃共同造成的.     

开市前议价期流动性形成的理论分析

股市开市前议价期存在于世界一些主要证券交易所。投资者可以在这段时间内自由地、无成本地提交、修改或者撤销不受限制的交易指令。在信息不对称和流动性提供者参与市场必须支付成本的假设下,我们构建一个简单模型,考察了存在和术存在开市前议价期两种市场机制下的流动性形成情况。定义了这个模型的均衡解,证明了开市前议价期提高了市场流动性和社会福利。     

基于中国股市微观结构的流动性与执行成本分析

运用市场微观结构理论来分析中国股市的交易制度、流动性和执行成本后发现:(1)在佣金和交易税相等的条件下,B股的知情交易者执行成本普遍大于A股,导致B股的流动性小于A股,买卖价差显著大于A股,表明投资者对B股交易要求较高的风险报酬;(2)一旦控制住执行成本中普通交易者对知情交易者所要求的风险补偿,A、B股买卖价差的区别就消失了。因此,证券管理部门应在B股市场引入做市商制度并在微观结构理论的指导下,加强交易监管系统,从而提高B股的流动性并降低其执行成本。     

European quanto option pricing in presence of liquidity risk

In this paper, we study the pricing problems of the European quanto options in which the underlying foreign asset is in imperfectly liquid markets. First, we assume that the dynamics of the underlying foreign asset price are affected by market liquidity and propose a liquidity-adjusted quanto model. This allows for the effects of market liquidity on European quanto option pricing. And then we derive the analytical pricing formulas for four different types of European quanto options. Finally, we empirically investigate the pricing performance of our proposed model with a European quanto construction involving the SSE 50 ETF, as the underlying asset, and the CNY/HKD exchange rate. Empirical results demonstrate that the pricing accuracy of the proposed model is markedly superior to that of the Black-Scholes quanto model. In other words, allowing for liquidity risk in the framework of European quanto option pricing can make markedly improvements in fitting the real market data. Particularly, the improvement rate is high for medium-term and out-of-the-money options. Moreover, these results are robust for different liquidity measures.     

Bank profitability in the Eurasian Economic Union: Do funding liquidity and systemic importance matter?

The post-crisis regulatory architecture targets greater banking stability by imposing additional capital and liquidity requirements. Profit persistence, however, remains an important factor for attaining this goal. Using annual data for 2008–2017, this study analyzes the relationship between funding stability, systemic importance, and the profitability of banks in the three founding states of the Eurasian Economic Union (EAEU): Russia, Kazakhstan, and Belarus. The results show a strong degree of stability in net interest margin (NIM) and a lack of persistence in return on assets (ROA). Compliance with the minimum level of the Net Stable Funding Ratio (NSFR) reduces both the funding liquidity risk and the NIM of EAEU banks. Moreover, systemically important banks in the region historically operate at a lower interest spread and less prudent NSFR, which implies a potentially greater adverse effect on their NIM. Bank-specific variables have various impacts depending on the measure of profitability. The results also highlight that greater market concentration protects the NIM and negatively impacts the ROA of EAEU banks. Finally, Western sanctions have a destabilizing effect on the NIM of EAEU banks, but not on systemically important banks.     

The market quality of commodity futures markets

To study the market quality of commodity futures markets, we construct a commodity futures market quality index from the perspective of liquidity, efficiency, and volatility. Based on the market quality index, the Chinese commodity futures market operates steadily. The metal futures market is more efficient and stable than the market for agricultural futures. The Chinese commodity futures market is less liquid and more volatile than the U.S. market. We examine the determinants of market quality and find that macroeconomic variables and futures market contracts are significantly related to the market quality of Chinese commodity futures.
