高校家庭经济困难学生资助体系问题分析及对策研究

高校目前建立的多元化家庭经济困难学生资助体系,对家庭经济困难学生进行资助,但还存在一些不足。本文围绕以学生为本的核心思想,结合新形势新背景,通过分析高校家庭经济困难学生资助情况现状,指出家庭经济困难学生资助工作体系存在的问题,并提出一些建议,以期完善该体系。     

北美自由贸易区经济周期协动性的实证研究

自《北关自由贸易协议》签订并实施以来,美国、加拿大、墨西哥三国间的经贸联系日益密切。三国间经贸投资联系的加强必然会作用于三国宏观经济波动的传导,并改变北美自由贸易区内美、加、墨三国经济周期协同的特点。本文首先探讨了《北美自由贸易协议》对美国、加拿大、墨西哥三国间贸易与投资的积极效应,然后对三国在北美自由贸易区成立前后的经济周期协动性变化的特征事实进行了分析,最后考察并检验了《北美自由贸易协议》对三国间经济周期协动性的影响。     

A DYNAMIC ANALYSIS OF COOPERATIVE RESEARCH IN THE SEMICONDUCTOR INDUSTRY*

In this article I construct a dynamic oligopoly model of research joint ventures (RJVs) where firms, investing to improve product quality, fully share the rewards of research success. RJVs benefit firms by eliminating duplicative research efforts, but firms also give up the possibility of becoming a solo innovator. Consumers benefit from lower prices, but may have to wait longer for new products to arrive. I show that RJVs are welfare enhancing by quantitatively evaluating these trade‐offs with data from the semiconductor industry. I also analyze how changes in product market competition affect research cooperation.     

责任导向会促进年长员工知识分享吗？基于主动动机模型

全球劳动力老化的严峻形势下,年长员工能否主动分享知识经验,对充分开发年长人力资本、促进企业可持续发展具有重要意义。基于主动动机模型,本文从责任导向视角探讨了年长员工知识分享行为的促发机制和边界条件。通过线性回归和蒙特卡洛拔靴法对200份40岁以上在职员工三时点配对数据进行分析,结果表明：责任导向会通过提升年长员工的建设性责任知觉进而激发其知识分享;反年龄歧视氛围感知对这一作用过程具有权变影响。本文丰富了年长员工知识分享行为的前因研究,对企业如何积极应对职场老龄化与年长员工知识传承具有启示意义。     

东湖国家自主创新示范区“杠杆工程”建设研究

在分析东湖高新区自有的优势和问题、面临的机遇与挑战的基础上,依据"四三结构"模型细分了东湖国家自主创新示范区的定位与目标;运用"四三结构"模型的要素协同机理提出了东湖国家自主创新示范区建设的杠杆工程——重大专项工程、中小企业成长工程、"两化"融合工程;最后探讨了使"杠杆工程"付诸实施的关键措施。     

体面劳动问题研究的新进展与未来研究展望

全球化加剧了劳资关系的不平衡状态,强资本弱劳工的局面得以维护并日益加强,资方为追求利益最大化而忽视劳动者利益的事情屡屡发生。随着转型时期经济社会改革的深入推进,劳资关系问题也越来越引起人们的关注并成为社会的焦点问题之一,全面实现体面劳动成为各级政府的重要方针,企业、各类劳动组织以及劳动者都对实现体面劳动发出了强烈的呼声。金融危机后体面劳动研究有了新进展,未来体面劳动问题研究也大有可为。     

人们关注的是分配动机还是分配结果?——最后通牒实验视角下两种公平观的考察

本文通过设计一组最后通牒实验考察了分配动机的公平和分配结果的公平对人的行为决策的影响,并分别从浙江和北京两地获取了相关实验数据。采用角色随机分配的简化最后通牒实验,通过提议者不同可选分配方案向响应者发送的信号,考察对提议者的"动机是否公平"从而响应者是否有相应的不同拒绝率。实验结果表明,响应者对提议者"分配动机的公平"有显著不同的反应,说明基于动机的互惠偏好确实在人们的行为决策中扮演重要角色。同时本文通过一组修正型的最后通牒实验从分配结果公平的角度考察了其影响机制,发现分别在保证博弈实验中38%的被试拒绝行为,以及免惩罚博弈中89%的被试拒绝行为,不能被差异厌恶偏好理论进行解释。本文实验的结果在于说明分配动机的公平比分配结果的公平更会影响人们的决策行为,其暗含的政策含义即分配过程的公平比分配结果的公平更为重要。     

On Gravity,Specialization and Intra‐industry Trade

Contrary to the popular belief, specialization is not necessary for gravity equations. This paper shows that the simple gravity equation holds if and only if the market share of an exporting country is constant across all importing countries. Specialization is just one special case satisfying this condition. The constant‐share condition can hold in a variety of situations where multiple producers compete with a homogeneous good. Further, this paper shows that the ratio of bilateral trade to the product of partner incomes is increasing in the extent of specialization and in the intensity of intra‐industry trade. Since the relationship is not model‐specific, the correlations among these variables do not support any specific model.     

国有企业负债规模的量化研究

负债经营,已成为社会主义市场经济条件下的企业经营过程中的一个普遍现象。但负债有利（财务杠杆效应）也有弊（财务风险）,如何从定量方面去权衡二者,这正是本文的出发点。同时本文还对目前国有企业的负债现状、形成原因进行了考查,进而提出使国有企业走出债务过度困境的对策建议。     

The Relation Among Targets' R&D Activities, Acquirers' Returns, and In-Process R&D in the US

Abstract:  Using a sample of 129 mergers and acquisitions (M&As) in the US between publicly traded acquirers and targets in research and development (R&D) intensive industries over the period of 1994-2004 and a size- and industry-matched sample, we examine the relation among targets' R&D activities, the probability of acquirers' writing-off in-process R&D (IPRD), and acquirers' returns around the time of M&A announcements. We find that firms acquiring targets with higher R&D investments tend to write off some of the acquired R&D assets upon the completion of the M&As. We also find that the median cumulative abnormal return during the three days around M&A announcements for acquirers with subsequent IPRD write-offs is −2.73% while the return for acquirers without IPRD write-offs is −0.60%. This suggests that acquirers' stock returns around M&A announcements are much lower when investors expect acquirers to expense IPRD. The results are consistent with our conjecture that acquirers tend to write-off IPRD when they acquire overvalued targets. We also find that IPRD write-offs do not increase earnings or stock returns of acquirers after M&As, which is inconsistent with an earnings management hypothesis.
