Return generating processes of long-term bonds and measurement of risk: Theory and empirical tests

Using a continuous-time framework, Kazemi (1992) shows that changes in prices of long-term bonds could be perfectly correlated with changes in the representative investor's marginal utility of wealth. Therefore, the equilibrium expected excess return on any security would be proportional to its covariance with changes in prices of long-term bonds. The present paper first extends the above result to a discrete time framework and shows that there are significant differences between the continuous time and discrete time versions of the model. Second, we test an empirical implication of this result; the evidence supports the theoretical model.

Which Factors Affect Bond Underwriting Fees? The Role of Banking Relationships

The question of which factors are relevant in determining bond underwriting fees is empirically investigated by analysing 2,202 bond issues completed by European firms during the 1993 – 2003 period. Four major results emerge from the analysis. First, the introduction of the single currency in 1999 has generated an increase in competition among banks, and, as a result, a reduction in underwriting fees. Second, a strong relationship with the issuer's main bank reduces the level of underwriting fees. Third, new issuers are charged with lower underwriter fees relative to firms that have completed issues without building any strong relationship with a bank. Fourth, higher reputation banks charge lower underwriting fees. The implications of these findings are also discussed.     

关于发展我国市政债券及市场的几点思考

我国＂十二五＂期间将积极稳妥推进城镇化,提升城镇发展质量和水平。在资金来源渠道有限的情况下,我们可以借鉴美国发行市政债券促进地方城市基础建设的经验和做法,改变我国城镇基础建设设施落后,投入不足的现状,按照市场经济的要求,逐步建立市场化、多渠道、多层次的资金筹措新体制。通过发行市政债券将更多的社会资金引入公共部门,推动我国城镇化进程。     

Insider employee stock option trading and stock prices

The question of which factors determine corporate bonds pricing is investigated by analysing the spreads of eurobonds issued by major G-10 companies during the 1991–2001 period. Three main results emerge from the analysis. First, bond ratings appear as the most important determinant of yield spreads, with investors’ reliance on rating agencies judgments increasing over time. Second, the primary market efficiency and the expected secondary market liquidity are not relevant explanatory factors of spreads cross-sectional variability. Finally, rating agencies adopt a different, ‘through the cycle’, evaluation criteria of default risk with respect to the forward looking one adopted by bond investors.     

Wealth effects of convertible-bond and warrant-bond offerings: a meta-analysis

The literature on wealth effects associated with the announcements of convertible-bond and warrant-bond offerings is reviewed. The findings of 35 event studies, which include 84 sub-samples and 6310 announcements, are analysed using meta-analysis. We find a mean cumulative abnormal return of?1.14% for convertibles compared with?0.02% for warrant bonds, the significant difference confirming a relative advantage for warrant bonds. Abnormal returns for hybrid securities issued in the USA are significantly more negative than those issued in other countries. In addition, issuing hybrid securities to refund debt does not seem to be favoured by investors. Finally, several factors identified as important by theory or in prior research are not significant within our cross-study models, suggesting that more evidence is needed to confirm whether they are robust.     

Emerging Bond Market Volatility and Country Spreads

Using JPMorgan's emerging market bond index, this paper analyzes how increases in country credit spreads can persist in emerging bond markets. The results of T-GARCH regressions show that, during financial crisis periods, emerging countries' credit spreads may increase persistently as a result of interaction between changes in spreads and volatilities, making emerging bond markets more turbulent. The results suggest that emerging countries should endeavor to develop a stabilization mechanism by enhancing information efficiency in bond markets. In particular, because Asian countries have experienced persistent, overreactive volatility, this paper implies that Asian countries should work together more closely during financial crisis periods.     

并购重组需要发挥并购基金和高收益债券等债券产品的作用

CONVERTIBLE BOND PRICING MODELS

Convertible bonds are an important segment of the corporate bond market, with worldwide outstandings approaching US$235 billion. Simple pricing models value a convertible bond as being equivalent to a straight bond with an embedded option that enables the bond holder to convert to a specific amount of common stock. The straight bond is subject to both interest rate and credit risk, whereas the option to convert is dependent on the underlying stock price, which exposes the convertible bond holder to equity risk. The complexity of these features means that convertible bonds tend to be treated casually in major derivatives and corporate finance textbooks. This paper presents a survey of the theoretical and empirical aspects of convertible bond pricing. The limitations of these studies are highlighted to identify those areas of research that may improve the valuation process and facilitate the application of these securities for corporate financing.
