Do Managers of U.S. Defined Benefit Pension Plan Sponsors Use Regulatory Freedom Strategically?

We use historical particularities of pension funding law to investigate whether managers of U.S. corporate defined benefit pension plan sponsors strategically use regulatory freedom to lower the reported value of pension liabilities, and hence required cash contributions. For some years, pension plans were required to estimate two liabilities—one with mandated discount rates and mortality assumptions, and another where these could be chosen freely. Using a sample of 11,963 plans, we find that the regulated liability exceeds the unregulated measure by 10% and the difference further increases for underfunded pension plans. Underfunded plans tend to assume substantially higher discount rates and lower life expectancy. The effect persists both in the cross‐section of plans and over time and it serves to reduce cash contributions. We further show that plan sponsor managers use the freed‐up cash for corporate investment and that credit risk is unlikely to explain the finding.

产业异质性、税收激励与自主创新

以2007-2016年中国战略性新兴产业A股上市公司数据为研究样本,从企业研发投入和专利产出两个维度,考察税收优惠政策与企业技术创新之间的关系。结果发现：①税收优惠政策对于企业自主创新具有激励作用,有效促进了企业研发投入和专利产出;②基于企业所属产业异质性视角发现,税收优惠政策对于八大战略性新兴产业企业的创新作用存在显著差异：对于新一代信息技术、高端装备制造业、节能环保等产业研发投入和专利产出具有激励作用,但对新能源产业的创新投入、生物产业和新能源汽车产业的专利产出具有抑制作用。研究结论在一定程度上解释了现有研究关于税收优惠政策“激励效应”和“抑制效应”的争议,也对完善中国创新税收激励制度具有借鉴意义。     

交互效应视角下政府补助、内部资源与创新绩效关系研究

以我国战略性新兴产业上市企业为研究对象,构建包含政府补助、内部资源和企业创新绩效的创新系统。建立PVAR模型,通过脉冲响应和方差分解等方法分析系统要素间的动态交互作用。研究结果表明：在企业创新系统内,创新资源促进企业创新绩效提升的效果最显著,政府补助次之,政治资源最弱;进一步探究发现,创新绩效能够实现对内部资源的积极反馈,该反馈作用是快速响应的。此外,企业资源和创新绩效冲击对政府补助的影响程度很小,本期政府补助主要受到自身波动的影响。     

海洋空间利用年度计划内涵研究与制度框架构建

海洋空间利用年度计划是自然资源部基于其国土空间用途管制职责提出的海洋空间资源管理新思路。基于当前海洋资源管理面临问题、生态文明体制改革要求以及空间资源计划管理经验,研究并提出海洋空间利用计划的内涵;并在此基础上,提出了海洋空间利用年度计划的构建原则、目标和制度体系。通过以上研究,拟为海洋空间利用年度计划制度的建立和实施提供技术支撑和决策支持。     

QM在SAP R/3系统中的运行原理

SAP公司,在中国企业管理界来说绝对不会陌生,SAP可以说是ERP的代名词。SAP公司的R/3系统凭借其自身系统的完美性、极高的成功率,令无数企业爱不释手,但其不匪的身价却又使企业有可望而不可求之感。SAPR/3系统是由SD模块、FI模块、CO模块等组成的企业资源管理系统,且每一个模块都在系统中发挥极其重要的作用。     

Judgment aggregation in search for the truth

We analyze the problem of aggregating judgments over multiple issues from the perspective of whether aggregate judgments manage to efficiently use all voters' private information. While new in judgment aggregation theory, this perspective is familiar in a different body of literature about voting between two alternatives where voters' disagreements stem from conflicts of information rather than of interest. Combining the two bodies of literature, we consider a simple judgment aggregation problem and model the private information underlying voters' judgments. Assuming that voters share a preference for true collective judgments, we analyze the resulting strategic incentives and determine which voting rules efficiently use all private information. We find that in certain, but not all cases a quota rule should be used, which decides on each issue according to whether the proportion of ‘yes’ votes exceeds a particular quota.     

The questions we ask: Opportunities and challenges for using big data analytics to strategically manage human capital resources

Big data analytics have transformed research in many fields, including the business areas of marketing, accounting and finance, and supply chain management. Yet, the discussion surrounding big data analytics in human resource management has primarily focused on job candidate screenings. In this article, we consider how significant strategic human capital questions can be addressed with big data analytics, enabling HR to enhance overall firm performance. We also examine how new data sources that help assess workforce performance in real time can assist in the identification and development of the knowledge stars that contribute to firm performance disproportionately as well as help reinforce firm capabilities. But in order for big data analytics to be successful in the HR field, regulatory and ethical challenges must also be addressed; these include privacy concerns and, in Europe, the General Data Protection Regulation (GDPR). We conclude by discussing how big data analytics can facilitate strategic change within HR and the organization as a whole.     

互联网能力与知识能力交互效应对知识创造绩效的传导机制:一个被中介的调节效应模型

整合资源基础观、知识基础观和动态能力理论，探讨互联网背景下互联网能力、知识能力两种企业内部因素交互作用对知识创造绩效的影响过程，尤其关注了具有前瞻性与反应性特征的战略柔性在这一过程中的重要作用，从而构建了一个被中介的调节效应模型。基于我国399家企业调研数据发现，互联网能力、知识能力均对战略柔性有显著正向影响；互联网能力与知识能力的交互作用通过战略柔性的中介机制促进企业知识创造绩效提升，即存在被中介的调节效应。在理论上，丰富了资源基础观和知识基础观在组织竞争优势构建方面的前因研究，在实践上，为处于互联网背景下的企业有效提升知识创造绩效提供了实践参考。
