Corporate Stock and Bond Return Correlations and Dynamic Adjustments of Capital Structure

This paper analyses the effects of dynamic correlations between stock and bond returns issued by the same firm on the speed of adjustment towards target leverage. The results show that the estimated correlations are time varying, show persistence and differ among firms. Analysis of the potential explanatory variables reveals that the correlations decrease with negative expectations about future aggregate risks, but only for firms with a low default probability. In contrast, correlations are positively associated with specific risk measures, especially idiosyncratic stock risk and financial leverage. The positive relationship between the correlations and the leverage ratio suggests that target leverage can be achieved faster when the stock–bond correlation is high. Our results show that this is the case.     

Stock liquidity and managerial short-termism

We examine whether stock liquidity exacerbates or mitigates managerial short-termism. Utilizing earnings management as a proxy for managerial short-termism, we establish three major findings. First, firms with liquid stocks engage in less accrual-based and real earnings management. Second, the effect of stock liquidity on earnings management is amplified for firms with high levels of managerial pay-for-performance sensitivity. Third, the positive association between the intensity of earnings management and firm cost of capital is evident only for firms with low stock liquidity. Our findings are consistent with the threat of blockholder exit as the main governance channel through which stock liquidity discourages opportunistic earnings management and mitigates managerial short-termism.     

What is the major determinant of cross-border banking flows?

This study examines the major determinant of cross-border credit flows through global banks across 70 countries. Employing a Bayesian dynamic latent factor model, we decompose volatilities of banking flows into the contribution of a global common factor, regional common factor, and country-specific factor. The results indicate that the global and regional common factor explains about 40–50 percent of volatility in overall cross-border banking flows. In particular, the contribution of the global common factor increased in the 2000s. Simultaneously, main determinants are largely heterogeneous across countries: this implies that the desirable policy response to credit inflows may differ for each host country.     

中小软件外包人力资本投资风险与控制策略研究

人力资本投资在服务外包总投资中占了最大比重,对软件外包企业来说更是如此.人力资本投资比重的增加给企业带来更大收益的同时也增加了企业的投资风险.目前,我国中小规模软件外包企业员工流动率高达20％,是社会平均流动率的两倍,形势严峻.本文力图突破传统的共性分析层面,从中小软件外包特性分析出发,探讨其人力资本投资风险的形成过程,并分别基于交易成本理论和期权理论提出控制人力资本投资风险的再外包和分阶段投资策略,为我国中小软件外包企业缓解高人力资本流失率,控制人力资本投资风险提供理论依据.

论药品专利和公共健康问题——以人权和“价值平衡”理论为视角

WTO建立的TRIPS协议将包括药品在内的一切发明都纳入可以给予专利保护的范围，这使发展中国家在解决本国因艾滋病、结核病和疟疾等传染病引起的公共健康问题时，和发达国家相关药品的专利保护之间产生冲突。从当前全球的公共健康现状出发，运用人权和“价值平衡”理论对此分析，可以得出这样的结论：作为基本人权，发展中国家人民的生命健康权应该优于知识产权加以保护。
