Bond pricing when the short-term interest rate follows a threshold process

This paper derives analytical solutions for arbitrage-free bond yields when the short-term interest rate follows an autoregressive process with the intercept switching endogenously. This process from the SETAR family is especially suited to capture the near-unit-root behaviour typically observed in the evolution of short-term interest rates. The derived yield functions, mapping the one-month rate into n-period yields, exhibit a convex/concave shape to the left and right of the threshold value, respectively, a pattern which is also found in US bond yield data. The longer the time to maturity, the more distinct the nonlinearity of the yield function becomes.     

A mean/variance approach to long-term fixed-income portfolio allocation

Abstract

Long-term investments in bonds offer known returns, but with risks corresponding to defaults of the underwriters. The excess return for a risky bond is measured by the spread between the expected yield and the risk-free rate. Similarly, the risk can be expressed in the form of a default spread, measuring the difference between the yield when no default occurs and the expected yield. For zero-coupon bonds and for actual market data, the default spread is proportional to the probability of default per year. The analysis of market data shows that the yield spread scales as the square root of the default spread. This relation expresses the risk premium over the risk-free rate that the bond market offers, similarly to the risk premium for equities. With these measures for risk and return, an optimal bond allocation scheme can be built following a mean/variance utility function. Straightforward computations allow us to obtain the optimal portfolio, depending on a pre-set risk-aversion level. As for equities, the optimal portfolio is a linear combination of one risk-free bond and a risky portfolio. Using the scaling law for the default spread allows us to obtain simple expressions for the value, yield and risk of the optimal portfolio.     

广西非金融企业债券融资现状及发展建议

广西非金融企业债券融资工具偏少,发行规模小,债券融资占比低,发展缓慢。究其原因是多方面的,有企业发行主体本身的内部因素,也有国家宏观政策环境和广西债券发行环境等方面的外部因素,文章在分析了影响广西非金融企业债券融资的主要相关因素的基础上提出了相应的发展建议。     

我国债券型开放式基金申赎行为的实证研究

债券型基金和偏股型基金的投资对象有所不同,在其申赎行为的影响因素上也自然有所不同。文章对影响我国债券型基金申购和赎回的主要因素进行了实证研究,结果表明在我国债券型基金的投资者中存在着"处置效应",也即是投资者倾向于赎回高收益率基金而持有低收益率基金,但并不存在收益率越高、净赎回越多的"赎回困惑"现象。另外,市场利率对债券型基金的申购和赎回也有重要影响。     

债务结构优化与企业创新——基于企业债券融资视角的研究

本文在我国保持宏观杠杆率基本稳定及实施创新驱动发展战略的现实背景下,从债券融资的视角,探讨债务结构优化对企业创新的影响。研究发现,债券融资与企业创新之间显著正相关,表明债券融资优化企业债务结构、提升企业创新能力的积极作用占据主导地位。进一步研究表明:(1)债券融资能够通过降低整体债务融资成本并延长整体债务期限促进企业创新;(2)债券融资对于银行贷款存在溢出效应,即企业通过债券融资,还能降低银行贷款利率、延长银行贷款期限,进而促进企业创新;(3)产品市场竞争和代理问题会在一定程度上削弱债券融资对企业创新的促进作用;(4)不同类型的债券对企业创新能力的作用存在异质性,债券发行的便利性是其影响企业创新的一个重要因素。     

Bond pricing in a hidden Markov model of the short rate

Abstract. We consider a diffusion type model for the short rate, where the drift and diffusion parameters are modulated by an underlying Markov process. The underlying Markov process is assumed to have a stochastic differential driven by Wiener processes and a marked point process. The model for the short rate thus falls within the category of hidden Markov models.     

Margin trading,short selling,and bond yield spread

Using a quasi-natural experiment, this study examines the effects of margin trading and short selling on bond yield spread in China. It finds that both margin trading and short selling can reduce bond yield spread. Additionally, it finds that margin trading lowers firms’ debt ratios and increases their credit ratings, which explains the reduced spread. In other words, margin trading can impact investors’ decisions by revealing positive information about a firm. Another finding is that short selling lowers the bond yield spread by decreasing earnings management, suggesting that short selling has an impact on investors’ decisions through its effect on corporate governance. Our results suggest that margin trading transmits positive information and short selling impacts firms’ policies. These results provide support for future regulations of margin trading and short selling.     

Locational effects and the cost of corporate bonds: the role of information

The public yield spreads of bonds vary widely between Chinese provinces/municipalities, with the average for the highest province double that of the lowest one. Although we find that these patterns are mainly attributable to economic and legal conditions, locational effects like geographic distance and public firm credit ratings also appear to be contributory. We show that these effects are induced by different regional informational environments and are robust to controlling for potential endogenous location choices.     

政府债券、宏观效应与政策调节--基于规模和流动性双重视角的DSGE效应分析

本文基于政府债券规模和流动性的双重视角,构建动态随机一般均衡模型,通过理论分析和数值模拟,研究二者对实体经济发展和金融风险变量的影响。研究显示:政府债券规模的增加促进了投资,刺激了产出和劳动供给,但过度扩张对实体经济也带来"挤占投资"和物价上升、消费下降等负面效应,同时通过债券作为金融资产的特性向金融部门蔓延并形成金融风险集聚;政府债券流动性增强一定程度上刺激了投资,促进了物价稳定,但也存在"挤占消费"和引起经济波动等负面效应;而政府债券流动性的提升有利于缓释金融风险,对实体经济长期可持续发展有益,但流动性过高也会带来系统性金融风险集聚。本文从促进政府债券一级市场和二级市场协同发展、总量和结构合理匹配、政府债券与实体经济有机契合、政府债券流动性管理与金融供给侧密切衔接等方面提出政策建议。     

State ownership and the cost of debt: Evidence from corporate bond issuances in China

Corporate credit risk can be reduced through implicit government guarantees. State-owned enterprises (SOEs) in China provide a distinctive setting to investigate government roles in corporate debt financing. We find that non-SOEs’ corporate bond issuance costs are significantly higher than those of SOEs. We also observe relatively lower bond issuance costs for firms controlled by the central government (CSOEs) than those controlled by local governments (LSOEs). In addition, we demonstrate that compared with SOEs, non-SOEs’ financial constraints are mitigated to a larger extent after the bond issuances. Overall, we show that state ownership plays an important role in determining corporate bond issuance costs.
