商业银行流动性危机传染机理研究

银行危机传染往往给一个国家或地区的经济带来巨大的损失.不完全的银行间拆借市场中隐含了更大的银行危机传染的可能性;银行间的长期资产越多,银行间拆借的短期利率和银行间存款的长期利率越高,银行间拆借市场就越稳定,在遭受流动性冲击时,这一市场发生银行危机传染的可能性就越小.适量的银行存款对传染效应具有阻碍作用.为防范系统性风险,中国商业银行应逐步建立完备的银行间存款市场,减少政府干预,让市场约束力来强化商业银行的风险管理意识.     

Liquidity Provision of Limit Order Trading in the Futures Market Under Bull and Bear Markets

Abstract:  This study investigates how limit orders affect liquidity in a purely order-driven futures market. Additionally, the possible asymmetric relationship between market depth and transitory volatility in bull and bear markets and the effect of institutional trading on liquidity provision behavior are examined as well. The empirical results demonstrate that subsequent market depth increases as transient volatility increases in bull markets. Market depth exhibits significantly positive relationship to subsequent transient volatility in bull markets. Additionally, although trading volume positively influences transient volatility in bull markets, no such relationship exists in bear markets. Liquidity provision decreases when institutional trading activity intensifies during bear markets. Thus, liquidity provision for limit orders differs between bull and bear markets.

虚拟经济的本质及影响实体经济的机理

虚拟经济的本质是一种价值权利的转移,它脱离了实体经济的具体生产过程,利用人们心理预期变化所造成的短期市场价格波动来赚取价差收益.在虚拟经济交易过程中,价值权利所代表的实物资本的物量和用途并未发生变化,也没有创造出新增价值,而只是实现了交易各方的货币收入再分配.虚拟经济对实体经济产生影响的关键性因素是虚拟经济的市场流动性,只有保持虚拟经济的适度流动性,才能真正起到改善实体经济融资环境、优化资源配置和产业结构的功能.实现虚拟经济和实体经济的稳定协调发展.     

Consumption and Portfolio Selection with Labor Income: A Continuous Time Approach

This paper studies the consumption and portfolio selection problem of an agent who is liquidity constrained and has uninsurable income risk. The paper investigates how the optimal consumption and asset allocation policies deviate from the case where the financial market is perfect, i.e., the case where there are no liquidity constraints and uninsurable income risk. In particular, the paper shows that, for a given level of financial wealth and labor income, optimal consumption is smaller and the optimal level of risk taking is lower in the case where the agent is liquidity constrained and has uninsurable income risk than in the case where the financial market is perfect. The paper also discusses how the agent assesses the value of lifetime labor income and relates this evaluation to optimal consumption and asset allocation policies.

MODELING LIQUIDITY EFFECTS IN DISCRETE TIME

We study optimal portfolio choices for an agent with the aim of maximizing utility from terminal wealth within a market with liquidity costs. Under some mild conditions, we show the existence of optimal portfolios and that the marginal utility of the optimal terminal wealth serves as a change of measure to turn the marginal price process of the optimal strategy into a martingale. Finally, we illustrate our results numerically in a Cox–Ross–Rubinstein binomial model with liquidity costs and find the reservation ask prices for simple European put options.     

Liquidity provision and optimal bank regulation

We extend the set of regulatory instruments for banks' liquidity provision by adding a policy instrument for controlling the fraction of perfectly-liquid accounts. We demonstrate how this instrument induces self-selection on behalf of depositors who are differentiated according to their probability of facing a liquidity shock. This self-selection leads to a market segmentation, which can break the bundling of deposits with liquidity risk and, thereby, enhance welfare. The optimal regulatory policy is explicitly characterized as a function of banks' investment return, and of depositors' gain from early withdrawals to fund a realized investment opportunity.     

产品市场竞争、流动性与公司投资

本文基于产品市场竞争的视角,探讨了公司流动性对投资的影响。使用中国A股上市公司1999~2012年的面板数据,通过联立方程组和三阶段最小二乘法进行实证检验,本文研究发现,当公司相对于行业竞争对手持有更多的流动性时,公司下一期的投资相对于行业竞争对手增加得也更多,同时相比于低掠夺风险行业,流动性对投资的正向作用在高掠夺风险行业中表现得更为明显。本文的研究表明,公司流动性具有战略价值。持有一定流动性的储备有助于公司在产品市场竞争中更好地抓住投资机会,从而获得竞争优势。
