A bootstrap test for jumps in financial economics

An i.i.d. bootstrap is applied for the ratio test of Barndorff-Nielsen and Shephard (2006) for jumps in jump diffusion processes. Asymptotic validity is established for the bootstrap test both under the null of no jump and under the alternative of jumps. Finite sample simulation shows that the bootstrap test has more stable size than the ratio test of Barndorff-Nielsen and Shephard (2006).     

Applying agent-based modeling to the evolution of eco-industrial systems

Agent-based modeling is simply a modeling technique for describing complex adaptive systems in a form that can be solved by computers. In this paper, agent-based modeling is applied to eco-industrial systems to gain new insights into their behavior. The factory in the eco-industrial systems is taken as an agent, and the objects, attributes and behaviors are determined. Some important interaction mechanisms between agents are also designed. Besides, the sustainability evolution is also studied through emergy theory. More importantly, a new concept, the Internal-flow emergy, is used to indicate the evolution direction of an eco-industrial system. Finally, a hypothetical eco-industrial park utilizing natural gas and halite as the main raw material inputs is adopted as a case study to illustrate the effectiveness of the agent-based modeling.     

高管薪酬激励、董事会治理与并购绩效

本文选取2012-2016年间实施并购重组上市公司为研究样本,考察了高管薪酬激励、董事会治理对并购绩效的影响,并进一步探讨了董事会治理对高管薪酬激励与并购绩效关系的调节效应。研究表明,高管薪酬激励对并购绩效为显著负向影响,董事会规模、独立董事占比与并购绩效都存在显著负相关关系,但是随着董事会规模的扩大,独立董事占比增加,董事会规模、独立董事占比都能减弱高管薪酬激励对并购绩效负向作用,存在显著的调节作用。在此研究结论基础上,提出建立长效高管激励机制、优化董事会结构,提升董事会工作效率、保持适度的股权集中程度等建议。

多孔结构建筑材料力学性能的有限元分析

多孔材料是一种新兴的材料,制备较易,成本较低。相对于一般连续介质材料而言,多孔材料具有比强度高、比表面积高、相对密度低、重量轻、隔音、隔热等优点。它最大的特点是具有排列规则、大小可调的孔道结构,在建筑材料中也有很多的应用。因此,对非均匀孔洞与均匀孔洞建筑材料力学性能的研究是很重要的课题。论文通过建立非均匀孔洞和均匀孔洞的有限元模型,对比分析两种模型的受力性能,更好地进行多孔建筑材料的推广和使用。
