Overconfidence and tax avoidance: The role of CEO and CFO interaction

We investigate how overconfident CEOs and CFOs may interact to influence firms’ tax avoidance. We adopt an equity measure to capture overconfident CEOs and CFOs and utilize multiple measures to identify companies’ tax-avoidance activities. We document that CFOs, as CEOs’ business partners, play an important role in facilitating and executing overconfident CEOs’ decisions in regard to tax avoidance. Specifically, we find that companies are more likely to engage in tax-avoidance activities when they have both overconfident CEOs and overconfident CFOs, compared with companies that have other combinations of CEO/CFO overconfidence (e.g., an overconfident CEO with a non-overconfident CFO), which is consistent with the False Consensus Effect Theory. Our study helps investors, regulators, and policymakers understand companies’ decision-making processes with regard to tax avoidance.     

股价信息含量与投资-股价敏感性——基于融资融券的准自然实验

本文利用2006-2015年间的数据研究了融资融券对投资-股价敏感性的影响。利用融资融券作为股价信息含量的一个外生冲击变量,本文研究发现,我国A股市场确实存在反馈效应,融资融券政策的实施增强了标的公司投资-股价敏感性,这个结论在采用倾向得分模型(PSM)配对后依然成立,说明融资融券使股价融入了更多有利于管理层投资决策的信息。其次,融资融券对投资-股价敏感性的影响在机构投资者比例高、流动性高、处于新兴行业的这类管理层反馈效应更强的股票组中更显著。参照以往研究考虑了融资约束对反馈效应的调节作用,同样发现融资融券对投资-股价敏感性的影响在国有企业和规模较大的企业组中更显著。最后,融资融券交易规模越大,投资对股价的敏感性越强。     

Progressive stress accelerated life tests under finite mixture models

In this paper, progressive stress accelerated life tests are considered when the lifetime of a product under use condition follows a finite mixture of distributions. The experiment is performed when each of the components in the mixture follows a general class of distributions which includes, among others, the Weibull, compound Weibull, power function, Gompertz and compound Gompertz distributions. It is assumed that the scale parameter of each component satisfies the inverse power low, the progressive stress is directly proportional to time and the cumulative exposure model for the effect of changing stress holds. Based on type-I censoring, the maximum likelihood estimates (MLEs) of the parameters under consideration are obtained. A special attention is paid to a mixture of two Rayleigh components. Simulation results are carried out to study the precision of the MLEs and to obtain confidence intervals for the parameters involved.     

具有网络效应的产品的价格竞争分析

具有网络效应的产品是指消费者在消费这种产品时所获得的效用会随着购买这种产品的其他消费者数量的增加而不断增加的产品。本文通过建立一个有两个厂商的离散动态决策模型，研究在分散决策的市场经济中生产具有网络效应的产品的厂商的价格决策对产品市场占有率的影响，价格决策影响产品市场占有率的动态演化的过程，以及市场均衡的务件和特征，包括产品不占有市场、占有部分市场以及上有今都市场的价格条件。     

反垄断法域外适用依据分析

反垄断法的域外适用包括多种情形,其依据也各不相同.其中由美国首先在司法中确立的“效果原则”对该类适用问题产生了重要影响,一方面对于保护本国的市场环境,效果原则确实具有积极的作用,但其引发的国家间主权和经济利益的冲突也使得该原则的适用受到了限制.对此,各国都采取了很多变通措施,并通过国际合作来缓解这些冲突,这对于我国的相关立法也具有启示作用.     

边疆民族地区经济增长与就业关系比较研究

通过建立GDP就业模型揭示经济增长与就业的内在关系。要增加就业降低失业率，必须保持快速和稳定的经济增长和提高GDP就业弹性。比较分析边疆少数民族地区和东部发达地区的GDP就业弹性，发现由于东部发达地区经济更依赖于资本和技术进步，其GDP就业弹性、GDP对就业的“指数效应”比边疆少数民族地区的小。同时随着边疆少数民族地区经济的资本有机构成逐渐提高和进一步的资本深化，GDP就业弹性也在逐渐下降。东部发达地区GDP对就业的“乘数效应”比边疆民族地区的大，说明了东部发达地区依然是吸收就业和农村剩余劳动力的主要地区，并提出增加就业的对策建议。     

公开市场业务与货币政策有效性——1997后中国货币政策传导梗阻的症结探析

1997年后我国一直实施“积极的”货币政策 ,但货币政策在传导过程中出现了梗阻 ,所起的作用远不尽如人意。公开市场业务是中央银行最重要的一个间接货币政策工具 ,作为公开市场业务主体的国债市场是央行公开市场操作的基本依托。我国国债市场在规模、流动性等方面发展滞后 ,仍是一个不成熟、不发达的市场 ,这使我国货币政策传导产生梗阻 ,严重抑制了货币政策效应的发挥     

Central Bank's interventions and the Fisher hypothesis: a threshold cointegration investigation

The long-run relationship between nominal interest rates and inflation is examined, allowing for structural breaks and asymmetric mean reversion. From a Threshold AutoRegressive (TAR) test applied to the residuals of the cointegration relationship (while allowing for both a break in the mean of the long-run equation and a smooth regime-transition), there is strong evidence for non-linear mean reversion properties for the real interest rates of the US Treasury Bill market. This suggests asymmetric changes to inflation shocks in the Central Bank's reaction function. The existence of different regimes is consistent with some interpretations of the monetary policies run by the Fed, such as credibility and opportunism.     

对外直接投资的贸易效应研究--基于中国经验的实证分析

对外直接投资与出口贸易之间的关系一直是相关理论和实证研究的争论主题。运用引力模型,对中国FD I的贸易效应进行实证分析表明:中国对东道国的直接投资促进中国对东道国的出口,但对从东道国的进口却具有替代效应。因此,大力促进中国对外直接投资,是促进中国的对外出口、绕开东道国贸易壁垒的重要途径。     

略论产业集群技术标准与集聚的正负效应之相关性

产业集群是现代产业发展过程中形成的一种具有典型特征的，介于企业和行业之间的产业组织形态。产业集聚的巨大正效应是产业集群形成和发展的重要原因。同时，产业集聚也会产生负效应，这些负效应可能导致产业集群发展缓慢，甚至衰退和消亡。找到正确有效的途径强化产业集聚的正效应，预防和消除产业集聚的负效应，是保持产业集群健康、持续发展的关键。技术标准对产业和企业的命运起着越来越重要的作用，技术标准与产业集群发展、运行秩序规范、负效应的防范与消除等方面都有着紧密的相关性，是促进产业集群发展的有效工具和手段。
