This paper shows that liquidity is an important source of priced risk in China. Using A-share stocks in Shanghai and Shenzhen Exchange over the period 2007–2017, we examine the influence of liquidity on stock returns. A new liquidity measure that captures multiple dimensions of liquidity is proposed. Fama-Macbeth cross-sectional regression shows that the expected return is negatively correlated with liquidity. Based on Fama and French (1993), we propose a five-factor pricing model by incorporating reversal factor and liquidity factor. Time-series regressions show that the liquidity factor makes significantly marginal contributions to explaining excess stock returns. The liquidity factor based on the proposed measure works better than alternative liquidity measures such as turnover, Amihud illiquidity measure and the measure in Liu (2006). 相似文献

Risk-averse investors may dislike decrease of liquidity rather than increase of liquidity, and thus there can be asymmetric preference in variation of liquidity. In addition, investors are likely to avoid extreme illiquidity. This paper examines whether the skewness of an individual firm’s liquidity capturing asymmetric distribution of liquidity and extreme illiquidity is priced in the US stock market. Using the skewness of the daily price impact, we find that it is positively priced, and this positive relation is significant up to eight months after controlling for other effects. Moreover, we find our results remain significant with the skewness of alternative liquidity measures, i.e., dollar-volume, and turnover. 相似文献

This paper provides a default-risky bond valuation model, which assumes that the issuer’s credit quality, modelled by the
intensity of default, is driven by a continuous-time Markov chain. The model accounts for default and liquidity risk as well
as incomplete information. A full-information semimartingale representation of a liquid defaultable bond price, which separates
three different types of risks—default, interest-rate and credit-quality, is obtained. The illiquidity is modelled as exogenously
specified stochastic reduction in the price of the bond, which adds more risks for the investors. A model of a market with
partially informed investors, belonging to specific investor classes and having access to discrete information sets about
credit quality, was specified. Valuations of defaultable bonds in this market were provided as well as price impacts of the
new information releases.

This paper focuses on the development of the interbank market risk premium in the Czech Republic during the global financial crisis. We explain the significant departure of interbank interest rates from the key monetary policy rate by a combination of different factors, including liquidity risk, counterparty risk, foreign influence, interbank relations, and strategic behavior. The results suggest a relevant role of market factors and some importance of counterparty risk. 相似文献

为了改善我国保障房建设中融资渠道缺乏的情况,结合当前我国国情,可以在保障房建设中引入PPP模式。而成功引入PPP模式的关键之一取决于整个项目的风险分担是否合理。PPP项目较长的项目周期蕴含着巨大的风险。可以通过分析PPP模式在保障房建设中可能产生的风险,提出可行的风险分担方案,对PPP模式在我国保障房建设中的广泛应用提供一定的理论依据。 相似文献

Bundling and Unbundling in Public–Private Partnerships: Implications for Risk Sharing in Urban Transport Projects 
下载免费PDF全文
下载免费PDF全文 Public–private partnership (PPP) projects may be organized in a variety of ways, depending on the level of integration of the so‐called Special Purpose Vehicle. Based on the analyses of four major PPP light rail projects in Spain, this article outlines two fundamentally different models of organizing the Special Purpose Vehicle in PPP projects; moreover, the article examines the central principles of these two different models of organizing the private sector Special Purpose Vehicle and their implications for risk sharing and project management in large‐scale infrastructure PPP projects. 相似文献

经济正飞速发展的中国,PPP项目不断增多,而PPP工程复杂、投资大、周期长,PPP项目中政府一般通过招标的方式选择合作伙伴,所以PPP模式下的招标举足轻重,其中的风险问题决定着项目的好坏与成败。基于此,文章就PPP项目招标阶段风险进行分类,并且用函数对风险等级进行划分,明确风险分配规则,整理分析了有效的风险控制措施,最后进行工程实例剖析得出相关结论,希望可以为PPP项目的招标提供一个有效的借鉴和参考。 相似文献

During the 2007–2009 financial crisis, US subprime mortgage risk exposures led to severe liquidity problems in several other foreign markets. Such risk contagion was caused by enormous changes in interest rates. Although risk contagion has been investigated by several literatures, the magnitude of propagated interest rate risk around global financial markets remains unexplored. Therefore, this study quantifies the degree to which the increased credit risk within the US financial system propagated to the European markets’ liquidity risks. Specifically, using a conditional value-at-risk (CoVaR) model, we quantitatively measure interest rate risk of a European country, by looking at the upside risk in distribution of changes in interest rate. And such propagation risk measure considers additional value-at-risk conditional on the interest rate movements in the US. The results show significantly positive differences between European country's value-at-risk conditional on the US financial markets being in a normal or distressed state. This propagating effect increased from 2007, and was particularly pronounced in the 2008–2009. In addition, the interest rate risk contagion is especially severe for some countries in the Euro regions with greater sovereign debt problems. Hence our result foretells the deterioration of the European sovereign debt crisis which started to unfold in 2010. Our work supplements the literature by successfully quantifying the magnitude of additional interest rate risk conditional on risk exposure from external sectors. 相似文献

关于债务期限结构影响因素之研究——来自沪深股市上市公司的经验证据 总被引：2，自引：0，他引：2
本文对2001至2006年度沪深股市中的575家上市公司债务期限的影响因素进行了研究。结果表明：影响上市公司债务期限的因素主要有流动性风险的一次方、流动性风险的二次方、资产期限、企业规模、财务杠杆、增长期权和边际税率;上市公司的债务融资决策考虑到了其自身的财务风险状况,因而尽管上市公司的债务期限偏短,但却是其理性思索的结果;偏短的债务期限导致上市公司存在着固定资产投资不足的倾向,因此当前应积极发展长期债务市场,努力降低上市公司进行长期债务融资的成本,从而诱使其借入更多的长期债务,以便有更多的长期资金用于其长期资产的投资,最终切实提高其盈利能力的可持续性。 相似文献

We reveal pitfalls in the hedging of insurance contracts with a minimum return guarantee on the underlying investment, e.g. an external mutual fund. We analyze basis risk entailed by hedging the guarantee with a dynamic portfolio of proxy assets for the funds. We also take account of liquidity risk which arises since the insurer may need to advance funds for performing the hedge. Based on a least-squares Monte Carlo simulation, we study the economic implications of basis and liquidity risks. We demonstrate that both risks may be surprisingly high and show how the design of the contract and the hedging strategy may help to alleviate them. 相似文献

Abstract This paper examines national environmental factors responsible for achieving global competitiveness in the pharmaceutical industry. The effect of national economic and regulatory environments on pharmaceutical market and industry structure is empirically tested using a sample consisting of both industrialized and developing countries. GNP was found to be a significant variable affecting market size, industry focus, and industry concentration. Price regulation had a significant negative effect on market demand for pharmaceuticals whereas approval time for new drugs was found to have no significant effect. Results provide important implications for public policy and global strategy. 相似文献

本文认为,债务期限结构错配是我国许多高速扩张企业出现流动性财务危机的主要原因之一,但在现有商业银行信贷期限结构错配和企业债券市场不发达的金融背景约束下,我国企业很难通过增加长期债务的方式来改变债务期限与资产期限错配的问题,唯有通过降低财务杠杆的方法来降低流动性风险。在现有金融市场条件下,企业现实的选择是债务期限结构错配和低财务杠杆,不能采用高财务杠杆方式来实现企业的高速增长,否则很容易陷入财务困境。 相似文献
