Oil price shocks and volatility spillovers in the Nigerian sovereign bond market

This paper investigates volatility spillover in the Nigerian sovereign bond market arising from oil price shocks, using Vector Autoregressive Moving Average ‐ Asymmetric Generalized Autoregressive Conditional Heteroscedasticity (VARMA‐AGARCH) model. The paper covers the period March 22, 2011 to April 14, 2016 and makes use of the daily data of the Nigerian Sovereign Bond, Brent oil and West Texas Intermediate (WTI), respectively. We endogenously and sequentially detect structural break points using the test of Bai and Perron (2003) framework. In order to accurately estimate the model, we modify it by incorporating the break points into the VARMA‐AGARCH model, a process which if ignored would lead to model misspecification. The results obtained demonstrate a significant cross‐market volatility transmission between oil and sovereign bond market with ample sensitivity to structural breaks. The study also computes optimum weight portfolio and hedge ratio both with and without structural breaks and results equally indicate sensitivity to structural breaks.     

The timeliness of performance information in determining executive compensation

We study whether boards of directors concentrate on performance near compensation decision times rather than providing consistent incentives for chief executive officers (CEO) throughout the fiscal year. We show empirically that managers can profit by moving sales revenue among fiscal quarters. Though this may suggest that boards use short-term trends when determining rewards, we find evidence consistent with boards tying pay to recent sales growth so as to use the best information about future performance. We also find that the timing of profits throughout the year does not affect CEO pay, which may suggest that smoothing firm income is important to CEOs.     

The capital market implications of the frequency of interim financial reporting: an international analysis

This study examines empirically the extent to which the frequency of interim financial reporting affects stock price volatility over the course of the fiscal year in four countries with different interim reporting regimes: the United States and Canada with quarterly reporting, and Great Britain and Australia with semi-annual interim reporting. It is hypothesized that, in the tradeoff between timeliness and predictive value of the interim reports, semi-annual interim reporting will lead to lesser price volatility after accounting for other potential influences. These expectations are supported in the results found. Moreover, additional tests conducted on American ADRs of British and Australian companies show that those firms have higher volatility than comparable purely domestic firms on their home stock exchanges.

东亚货币一体化的国际风险分担机制分析——基于第二代最优货币区理论的拓展

在经济全球化的背景下,区域货币一体化对于区域内各国的经济发展有着重要意义。当前的国际金融危机使东亚地区货币合作又重新进入人们的视野,关于东亚货币一体化的可行性分析也进入了一个崭新的阶段。此时,我们更需要从抵御风险,实现共同发展的角度来探讨东亚货币一体化。中国作为东亚区域内有影响力的大国,应对此问题有深入思考。本文对最优货币区理论进行了有益的拓展,建立了基于微观基础的国际风险分担机制模型,并运用动态优化的方法严格证明了货币一体化所形成的国际风险分担机制使成员方达到消费保险的目的,这为进一步推动东亚货币一体化的建设提供了新的理论依据。

技术独董、经济政策不确定性与企业创新产出

创新产出是企业创新能力的直观体现,也是企业价值创造的源泉。以2008—2017年披露了专利授权信息的中国A股上市公司为样本,研究了独立董事技术专长对企业创新产出的影响。结果显示：（1）技术独立董事显著地促进了企业创新产出,且这种促进作用受到经济政策不确定性的负向调节;（2）技术独立董事是通过提高企业的创新投入来促进企业的创新产出的;（3）技术独立董事兼职席位与企业创新产出呈倒U型关系。根据上述研究结论,企业应当增加技术独立董事的引入并适当限制技术独立董事在其他企业兼职的行为,以充分发挥技术独立董事的创新驱动效应,提高企业创新产出。     

基于DFSR模型房地产税收政策对房价影响研究——以上海市为例

以上海市为研究区域,构建包含驱动力、状态、响应指标的DFSR模型来分析房地产税收政策对房价响应的评价体系,其中利用主成份分析法确定驱动力指标综合得分,再根据量化的各项指标,明确房地产税收政策在房价影响中的地位。研究结果表明,房地产税收政策的调整呈明显的周期性变化,在政策调控力度强的情况下,政策对房价的影响是非常明显的。同时房地产税收政策调控具有时滞性,政策的调控力度与房价的变化并不完全同步。最后提出相应的改革措施,为优化房地产税收政策提供建议与参考。
