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.     

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

Pricing Bonds and Bond Options with Default Risk

The pricing of bonds and bond options with default risk is analysed in the general equilibrium model of Cox, Ingersoll, and Ross (1985). This model is extended by means of an additional parameter in order to deal with financial and credit risk simultaneously. The estimation of such a parameter, which can be considered as the market equivalent of an agencies' bond rating, allows to extract from current quotes the market perceptions of firm's credit risk. The general pricing model for defaultable zero-coupon bond is first derived in a simple discrete-time setting and then in continuous-time. The availability of an integrated model allows for the pricing of default-free options written on defaultable bonds and of vulnerable options written either on default-free bonds or defaultable bonds. A comparison between our results and those given by Jarrow and Turnbull (1995) is also presented.     

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.     

The impact of liquidity on inflation-linked bonds: A hypothetical indexed bonds approach

Sovereigns mainly issue inflation-linked bonds (ILB) in order to save money. More than 15 years’ experience with this financial instrument in the United States has led to the conclusion that these bonds are characterized by low liquidity issues. Recently, various papers have started to analyze the impact of liquidity on ILB yields. This paper develops a new strategy for estimating the liquidity premium based on Campbell and Shiller's (1996) hypothetical ILB yields. We find significant effects of ILB-specific liquidity measures for the United States, the United Kingdom and Canada. Based on these findings, we derive the liquidity premium in ILB yields, liquidity-adjusted estimates for the break-even inflation rate and the inflation risk premium. In the United States, for instance, the average of the liquidity premium is 0.56%-points, and the average liquidity-adjusted break-even inflation rate and inflation risk premium amount to 2.67%-points and 0.22%-points, respectively.

大陆高职院校毕业生赴台湾高校专升本探析

通过对2013年大陆高职院校毕业生赴台专升本实施情况的研究，分析大陆高职院校毕业生赴台专升本不理想的原因，如赴台专升本项目对报考生源资格的限制条件较为严格、赴台专升本项目的公布时间偏晚、台湾院校招生科系介绍及收费标准公布偏迟、在台湾高校学习的经济成本远大于大陆高校、台湾高校学历相比海外高校并不占优势、赴台专升本的学习成效存在不确定性等，提出要进一步放宽对赴台专升本项目的限制、完善赴台专升本项目信息内容并及时全面地向社会公开、通过各种形式减轻学生赴台专升本的经济压力、在教师和学生层面提升对台湾高校实力的认可度、利用台资企业对台湾高校学历的认可度为赴台专升本学生打开就业的大门等对策。
