Creating competitive advantage: Linking perspectives of organization learning,innovation behavior and intellectual capital

Drawing on learning theories and the intellectual capital (IC) theory, organizational learning research has discussed the benefits of searching for market opportunities and maintaining a competitive advantage in dynamic environments. To explain organizational performance and survival, the previous literature has focused mainly on what organizations do, but it has failed to address how and what they should do. This study argues that if hotel management is open-minded about exploratory and exploitative learning, it can open the door to capturing opportunity and competitive advantage through increased innovation behavior and human capital accumulation. Further, IC theory has also confirmed that social capital and relational capital will strengthen the relationship between innovation behavior and human capital. This study analyzes data from 595 hotel managers and finds strong support for the proposed hypotheses.     

Semiparametric diffusion estimation and application to a stock market index

The analysis of diffusion processes in financial models is crucially dependent on the form of the drift and diffusion coefficient functions. A new model for a stock market index process is proposed in which the index is decomposed into an average growth process and an ergodic diffusion. The ergodic diffusion part of the model is not directly observable. A methodology is developed for estimating and testing the coefficient functions of this unobserved diffusion process. The estimation is based on the observations of the index process and uses semiparametric and non-parametric techniques. The testing is performed via the wild bootstrap resampling technique. The method is illustrated on S&P 500 index data.     

工程造价司法鉴定专家证人制度浅析

随着科技、经济的不断发展,诉讼案件越来越多样化、复杂化,经常涉及一些专业的问题,给法官的审判带来种种困难.尤其是建设工程案件,工程造价的鉴定尤为复杂,鉴定机构和鉴定人员的专业水平参差不齐,这让法官审判更是难上加难.最高人民法院于2019年对《最高人民法院关于民事诉讼证据的若干规定》进行了修正,对专家证人做了明确的规定与...     

高校教育成本构成探析

随着教育事业的持续发展,高等教育的成本管理顺应需要发展起来,逐步成为高等学校财务管理的一项重要内容。明确辨析高等教育构成及内涵性质是进行高校教育成本核算、成本控制的前提和基础,具有十分重要的研究价值。在这种要求之下,本文分析了高等教育成本的内涵,教育成本的构成要素、内容及性质、介绍了中外高等教育成本的研究现状,总结出了高校教育成本的三种构成模式。     

风险传染的信息识别——基于网络借贷市场的实证

基于清华大学金融科技研究院互联网金融研究中心网络借贷平台数据库与网贷之家相关平台统计数据,通过构建Logit模型与Cox比例风险回归模型来研究2015年12月e租宝事件和2018年6月备案延期后的“爆雷”现象,本文着重考察投资者是否具备根据信息披露程度识别问题平台和正常平台的能力。本文发现,第一,信息披露程度是影响平台风险的重要因素:信息披露程度越高的平台,其运营时间越长,出现问题的可能性越低。第二,信息披露程度越高的平台对抗风险的能力越强。风险传染期内,信息披露程度较高的平台,其成交量受市场负面情绪的影响较小。上述两点表明,总体而言,投资者重视平台披露的信息,并具备一定的信息识别能力。最后本研究也发现,上述两次风险事件期出现的问题平台是市场出清所需,它们和正常运营平台存在较大差异,尚无证据表明大量正常平台被拖累成问题平台。     

诉讼效率的经济学分析

诉讼效率应当使全部的诉讼资源在司法机关之间和诉讼参与人之间得到均衡分配。诉讼效率的物质表现是诉讼资源的配置状况。高昂的诉讼机会成本经常使人们不选择诉讼而选择其他手段;诉讼效率成本是诉讼效率物质体现的种种消费,其收益是定纷止争的结果及定纷止争本身对整个社会秩序带来的效益。探求诉讼效率最佳状态可以转化为解决诉讼边际成本与边际收益如何处在相等点上的问题。     

The identification of fiscal and monetary policy in a structural VAR

Good economic management depends on understanding shocks from monetary policy, fiscal policy and other sources affecting the economy and their subsequent interactions. This paper presents a new methodology to disentangle such shocks in a structural VAR framework. The method combines identification via sign restrictions, cointegration and traditional exclusion restrictions within a system which explicitly models stationary and non-stationary variables and accounts for both permanent and temporary shocks. The usefulness of the approach is demonstrated on a small open economy where policy makers are actively considering the interaction between monetary and fiscal policies.
