Reading the stars: Determining human capital's value in the hiring process

Star employees are highly sought after by competitors and thus more likely to move from one company to another. However, not all the factors related to stardom are as mobile as the stars themselves. We argue that while simply possessing star status leads to increased movement, differences in the attributions of human capital and value appropriation will also influence a star's movement to competing firms. To test this, we analyzed the careers of 695 security analysts over a 10‐year period. We found that while stars are more likely to move to competing firms than nonstars, the difference in movement between stars and nonstars decreases as the status of their current firm and their tenure increases.     

An empirical study on credit card loan delinquency

Following the Basel II convention, consumer credit default is commonly defined as delinquency beyond a period of 90 days. In this study, rather than considering default as a binary variable, we dissect delinquency states further to investigate default behavior in greater detail. As such, we define three states—no delinquency, delinquency and serious delinquency—and estimate the probabilities of the transitions between states using extensive panel data from Korea, covering a wide range of behavioral information. Our findings have several economic implications. First, the factors that affect delinquency risk can differ from those that affect the transition from delinquency to serious delinquency. Second, the recent increase in the number of seriously delinquent accounts can be attributed to changes in the borrower age distribution. Third, macroeconomic conditions, especially differences in gross domestic product and consumption growth, have led to the recent increase in delinquent accounts. Fourth, the debt-to-income (DTI) ratio has a profound effect on transitions between delinquency states and thus affects both recovery and delinquency. Furthermore, this result is robust to controls for demographic and macroeconomic factors.     

创业韧性的驱动因素及其对创业行为选择的影响——一个基于QCA方法的研究

创业韧性作为创业者克服困境,自我恢复与成长的能力,可以帮助创业者或企业家在逆境中实现自我超越,促进创业成功.然而目前来说创业韧性的研究仍处于起步阶段,学者们重视韧性对创业活动的促进作用,而较少关注创业韧性的驱动因素.本文通过定性比较分析的方法(QCA)探索失败情境下不同因素的组态对创业韧性的影响后发现:①并不存在单一的核心条件会促使创业韧性的形成;②驱动创业韧性的形成分为四条路径,并就四条路径对结果进行讨论;③低创业失败恐惧与高创业经历在经济成本与社会成本缺失下对创业韧性的形成具有重要影响,并推动创业者继续展开创业活动,而不会一蹶不振,退出创业.     

技术创新网络分裂断层、知识权力与创新独占性——知识势差的调节作用

创新独占性可表征创新合作群体对于自身知识、技术创新成果的利用和分享程度，决定着创新合作群体能够在多大程度上从创新成果中获利。创新独占性具有外部排他性和内部互补性的显著特征，有必要从技术创新网络视角出发，审视创新子群间相互关系对创新独占性的影响机理。以参与合作研发的高新技术企业群体为研究对象，构建技术创新网络分裂断层对创新独占性影响路径的概念模型。结果显示：技术创新网络分裂断层对创新独占性产生正向影响，知识权力在技术创新网络分裂断层与创新独占性之间发挥中介作用，技术创新网络分裂断层对创新独占性的影响受知识势差的负向调节。

环境规制工具对环境友好型技术创新的区域性影响——以氢燃料电池技术为例

为了明确不同类型环境规制工具是否以及如何影响环境友好型技术创新，从而为环境规制政策制定提供有力依据，以氢燃料电池技术为例，基于中国2004—2017年省际面板数据，采用Sys GMM法进行实证检验，在此基础上，利用SPSS软件进一步将全国样本分为环境友好型技术创新高水平地区、中等水平地区以及低水平地区，检验环境规制工具影响环境友好型技术创新的区域性差异。结果显示，3种环境规制工具对环境友好型技术创新呈现出显著正向影响，且在环境友好型技术创新高水平地区，市场激励型和公众参与型环境规制工具的正向促进效应显著，但命令控制型环境规制工具并未对环境友好型技术创新形成有效激励；在环境友好型技术创新中等水平地区，市场激励型环境规制工具对环境友好型技术创新的负向影响显著，其余两种规制工具的激励效应不显著；在环境友好型技术创新低水平地区，仅有命令控制型环境规制工具显著影响环境友好型技术创新且表现为负向作用。     

采用锁频环和锁相环联合捕获的载波跟踪

针对传统锁频环-锁相环跟踪算法中环路状态转换过渡中出现频率阶跃的问题，提出了一种采用锁频环和锁相环联合捕获的方式替代单一锁频环进行捕获的改进算法，同时对环路状态转换的门限进行了推导。仿真结果表明，改进的算法在转换过程中更加平稳，环路性能得到了优化。在信噪比为-10 dB且存在加加速度时跟踪环路在转换时没有出现频率阶跃，达到了设计目的。     

Interdependence of ASEAN-5 Stock Markets from the US and Japan

Abstract

During the 12 years since 1992 when people started to use the dollar as a currency in Cambodia, the share of the dollar has reached more than 70% of the total currency. This dollarization phenomenon has resulted in large seigniorage losses for the Cambodian government. The costs are estimated up to US$682 million at the end of 2004 with an additional US$61 million lost annually. Furthermore, there are many other kinds of costs caused by the side effects of seigniorage loss. Without siegiorage, some monetary, fiscal and foreign trade policies are no longer available. Worsening the distortion of income distribution is another side effect. These are major costs of dollarization over the direct seigniorage loss. The benefits of dollarization include stabilizing price levels and lowering the risk of national default during a foreign currency crisis. It is not difficult to conclude that the costs of dollarization outweigh the benefits.

There are two de-dollarization methods. One is a policy that prohibits people from using the dollar as a currency by law. The other is the policy that widens the difference of the costs and the benefits of using dollars, also by law. Either method is applicable but it seems reasonable that the method of prohibition by direct law would be more effective and efficient than the other method, since 84% of the total population exclusively uses the riel in Cambodia.

It is totally dependent on the decision of the Cambodian government whether or not a de-dollarization policy is adopted. The results of the decision, for good or ill, will rest finally with the people of Cambodia.     

基于三阶段DEA模型的我国国有控股银行效率研究

本文以我国国有控股银行为样本,以2006年-2010年的年度数据为依据,选取利息支出、营业费用和贷款损失准备为投入变量,净利润为产出变量,并以GDP增长率、实际利率及存贷利差为环境变量,基于三阶段DEA模型分析法,研究了我国国有控股银行效率。结论表明,股份制改革给国有控股银行带来了规模效应,市场竞争度的提高增强了国有控股银行的经营效率,2006年以后国有控股银行的效率值显著提升。
