管理层权力制衡强度、债务约束与企业创新投资

企业创新是国家经济可持续增长的关键，受到管理层意愿的影响，因而需要对内部经营者的权力进行制衡。以2010-2018年我国A股上市公司为研究样本，实证检验管理层权力制衡强度对企业创新投资的影响，以及不同债务约束情境下高商业信用配置、高负债水平的调节效应，此外，还考察了产权性质的差异化影响。研究表明，管理层权力制衡强度越大，企业创新投资水平越高；高商业信用强化了该促进作用，而高负债水平弱化了该促进作用。进一步研究发现，管理层权力制衡强度与企业创新投资的关系在民企中更显著；国企能够更好地获得和运用商业信用，使其高商业信用对该关系的强化效应更显著；民企具有更强的债务约束，其高负债水平对该关系的弱化效应更明显。     

Merit versus maleness: How strategic positioning can mitigate external gender bias

Despite the proactive efforts of many firms to combat gender bias within their organizations, societal prejudices still disadvantage women leaders and the firms who employ them. This external gender bias shapes outside stakeholder evaluations of women leaders’ efforts in various ways, and firms need strategies to cope with this external gender bias. We examine the conditions that might alleviate this burden of external bias and what women leaders and top executives can do to leverage these conditions—from a strategic positioning perspective—that will effectively allow female leaders to differentiate their work. To do this, we synthesize and build upon evidence that the external gender bias against women leaders diminishes when they lead in areas that are unconventional rather than mainstream. We then propose a two-step process based on (1) identifying the likely threat of external gender bias, which is stronger in some industry contexts than others, and (2) leveraging unconventionality to circumvent male prototypical comparisons, thereby reducing the hazards of external gender bias.     

INTERNATIONAL RESERVE MANAGEMENT: A DRIFT‐SWITCHING REFLECTED JUMP‐DIFFUSION MODEL

We study the cost of shocks, that is, jump risk, with respect to reserve management when the reserve process is formulated as a drift‐switching jump diffusion with a reflecting barrier at 0. Inspired by the Brownian drift switching model, our model results in a more realistic dynamic behavior of international reserves than the buffer stock model. The new model can capture both the jump behavior in reserve dynamics and the leptokurtic feature of the increment distribution which has a higher peak and two asymmetric heavier tails than the normal distribution. Through the selection of an initial distribution that reflects certain steady state behaviors, the reserve process becomes a regenerative process. This selection enables us to derive a closed‐form expression for the total expected discounted cost of managing reserves, thus helping us to numerically find management strategies that minimize costs. The numerical results show that shocks at the reserve level have a significant effect on reserve management strategies and that model misspecification can result in nonnegligible additional costs.

The approach to transforming the traditional agricultural economy: a research on the multiple paths of poverty alleviation and transformation in rural China

Transforming a traditional agricultural economy into a modern economy is one of the main themes in economic development. Through theoretical and empirical analysis, this paper finds out that the key to transformation is to raise the economic value of people, to improve human capital investment and to match the stocks of physical and human capital. China’s rural economy is on the edge of economic take-off, and different zones may pursue different paths for transformation. The source of rural poverty is not the scarcity of income or consumption, but the deficiency of education, social security, medical care and economic opportunity, which we define as “capability poverty”. __________ Translated from The Journal of World Economy (世界经济), 2005,(2) (in Chinese)     

巩固和拓展党的执政资源

对于一个执政党来说,其执政资源丰厚与否,不仅关系到它能否履行好执政使命,而且还关系到它的执政地位是否稳固。在新的历史条件下,为了加强党的执政能力建设,巩固党的执政地位,我们就要从群众资源、经济资源、权力资源、理论资源和组织资源等各方面不断开拓党的执政资源。
