Corporate Governance and Corporate Bond Liquidity

Using a unique dataset of corporate bond trading information and corporate governance evaluation scores, this study examines the determinants of corporate bond market liquidity in Korea. In particular, this study explores whether corporate governance performance of a company influences liquidity of bonds issued by the company. The paper reports three important findings. First, the issue size and age of bond are important determinants of bond liquidity. Second, liquidity of corporate bonds is influenced by changes in macroeconomic conditions. Third, and most importantly, better corporate governance increases liquidity of corporate bonds. This result suggests that corporate governance is an important determinant of bond liquidity, as it lowers transaction costs by improving transparency and reducing asymmetry of information. This paper contributes to the literature by providing new evidence that corporate governance performance is an important determinant of liquidity in corporate bond markets.

An Inquiry into the Feasibility of a Catastrophe Risk Bond Market

Catastrophe risk bond is the product of financial integration and financial innovation, which have been attached great importance by both academic circle and business circle since it was invented. After describing the theories of demand and supply for catastrophic risk bond, the paper continues to test these theories with models, and then makes a conclusion that the demand of investors for catastrophic risk bond is increasing, but the reinsurance companies have not collected the expected benefits by issuing such kind of bonds.     

信用评级高估与融资的所有制歧视——基于中国公司债的数据

为了分析发债主体所有制性质对公司债发行定价影响的作用机理,从信用评级高估的假设出发,将所有制性质的定价作用区分为直接效应和间接效应,基于贝叶斯法则得出两个推断：评级高估会导致发债主体所有制性质对公司债发行定价的直接效应;高信用等级公司债发行定价会受到发债主体所有制性质的直接影响,低信用等级公司债则不然。通过对2007—2013年沪深两市公开发行的公司债进行实证分析,推断得到了验证。这些分析有利于剖析民营企业融资歧视的形成机制。     

抓住机遇,开拓进取,努力开创内蒙古高校科技工作的新局面

近年来,内蒙古高校科技工作取得了显著成效:综合科技实力持续提高;教学与科研二元化发展模式基本确立;学科结构不断优化;培养出一批本土学科带头人;有效整合了创新资源。同时也面临着如下问题:高校科技工作与自治区经济社会重大需求不相适应;科技创新动力不足;科技投入力度不够;创新平台综合利用和集约化程度差;政策支撑环节仍然薄弱。因此,要努力抓好一项规划;提升两个能力;实施三大行动;在科技计划中突出六大重点,实现高效科技工作新局面。     

中国公司债券交易量与价格波动的关系

使用中国沪深证券交易所的公司债数据,检验了债券交易量与价格波动的线性关系和非线性尾部相关性,分析了债券流动性水平对量价关系的影响,研究了债券量价关系的时变特征。结果表明:中国公司债市场中债券交易量与价格波动之间存在显著的线性关系;债券流动性水平对量价关系有显著影响,债券流动性水平越高(低),则量价关系越弱(强);债券交易量与价格波动存在非对称的下尾相关性;债券量价关系具有时变性,市场低风险时期量价关系较弱,市场高风险时期量价关系较强。     

矿物微粉对水泥基混合料抗压强度的影响

为了了解矿物微粉对混凝土性能的影响,利用可压缩堆积模型(CPM)计算了不同体系胶凝材料的堆积密实度,研究了矿物微粉级配及其相对掺量对低水胶比水泥基混合料抗压强度的影响。结果表明,胶凝材料的堆积密实度与水泥基混合料的抗压强度有很强的对应关系;当堆积密实度相差不大而化学效应相差较大时,化学效应越大,抗压强度越大。

Exploring the dynamic spillover of cryptocurrency environmental attention across the commodities,green bonds,and environment-related stocks

We analyze the dynamic spillover impact of cryptocurrency environmental attention (ICEA) on three asset classes: commodities, green bonds (GBs), and environment-related stocks. Our wavelet-based analysis suggests that ICEA is sharply escalated after the first quarter of 2021. During this period of intense attention, only the soybean commodity and Solactive GB tend to move positively and negatively with ICEA, respectively. Accordingly, the clean energy, sustainability, and Environmental, Social, and Governance (ESG) stock indices are positively associated with ICEA during 2018–2019 at the medium frequency bands. In most periods and frequency domains, most commodities, GBs, and environment-related stocks are not strongly linked to ICEA. Moreover, Diebold and Yilmaz’s (2014) spillover estimations signify no strong spillover effect of ICEA on the asset classes considered in this study. These findings are further corroborated by the wavelet-based Granger causality analysis. Moreover, our quantile regression (QR) estimations suggest that most assets are adversely influenced by ICEA, depending on the market conditions. Our research conveys some novel and vital policy ramifications to both investors and policymakers.
