Are non‐audit services associated with firm value? Evidence from financial information system‐related services

The purchase of non‐audit services from incumbent auditors has generated considerable attention. Surprisingly, limited empirical evidence exists on the association of non‐audit services with firm value. Focusing on services related to financial information system (FIS), we find that the market value of equity is greater for firms that purchase FIS‐related services from their incumbent auditors relative to firms that do not. The levels of FIS fees are also positively related to firm value after controlling for total other fees, or total other non‐audit fees. Hence, despite the negative perception associated with non‐audit services, investors regard FIS‐related services as value‐adding activities.

衍生金融工具的演变对公司法股东至上原则的影响及修正

传统公司法以股东至上为基本原则,并以此为轴心进行系列制度安排.衍生金融工具的应用,使股票与债券等原生金融工具蕴涵的收益与风险要素得以重新打包组合,满足投资者个性化需求.但是附着原生金融工具上的法律的权利与义务却未能完全对应地转移,使得股权与债权的界线逐渐模糊,形成公司法对除股东以外的其他类型投资者保护的缺口.公司法应该对这些新型的交易关系进行确认,对股东至上原则进行修正,调整保护对象和范围,容纳更多的与公司发展攸关的利益主体的利益诉求.     

投资者法律保护、股权集中度与大股东行为

在不同的法系和国家中,对投资者的法律保护存在很大的差异。作为对投资者法律保护的替代,在投资者法律保护薄弱的国家,股权结构相对集中。为了保护投资者的利益,我国应该完善对投资者的法律保护,提高执法质量和会计质量,促进股权的适度集中,限制控制股东的掠夺行为。     

The law and ethics of big data analytics: A new role for international human rights in the search for global standards

The Economist recently declared that digital information has overtaken oil as the world’s most valuable commodity. Big data technology is inherently global and borderless, yet little international consensus exists over what standards should govern its use. One source of global standards benefitting from considerable international consensus might be used to fill the gap: international human rights law. This article considers the extent to which international human rights law operates as a legal or ethical constraint on global commercial use of big data technologies. By providing clear baseline standards that apply worldwide, human rights can help shape cultural norms—implemented as ethical practices and global policies and procedures—about what businesses should do with their information technologies. In this way, human rights could play a broad and important role in shaping business thinking about the proper handling of this increasingly valuable commodity in the modern global society.     

数据交易市场双边匹配模型与决策方法研究

针对平台视角下的数据交易供需双边匹配问题,基于双边匹配理论,提出了考虑模糊语言评价信息、区间数评价信息和0-1评价信息的混合型多属性匹配决策方法并定义了属性匹配满意度函数。以供需主体最大匹配满意度为目标,构建了数据交易供需双边匹配的多目标优化模型,并设计模型求解算法,将多目标化模型转化为单目标线性规划模型进行求解,以获取匹配结果。结果表明,通过对供需双方需求信息的详细分析,双边匹配结果能在最大程度上满足双方需求,同时,优化模型具有合理性及有效性。     

大数据环境特征对IT外包项目绩效的影响

对知识密集型的IT外包行业来说,大数据环境成为接包企业潜在的知识来源。然而,大数据环境是否真的促进IT接包项目绩效？如何从中获益？现有文献对这些问题缺乏研究。基于资源编排理论,探讨了大数据易得性和冗杂性对IT接包项目绩效的直接影响,检验了功能组合和专项突破两种软件开发策略的调节作用,提出6条假设,采用195个IT外包项目数据进行检验。研究发现,大数据易得性显著提高接包项目绩效,而大数据冗杂性显著降低项目绩效;功能组合策略增强而专项突破策略削弱了大数据易得性对项目绩效的促进作用;两种开发策略对大数据冗杂性与项目绩效关系的调节作用不显著。

Investor Attention and Earnings Management around the World

This study examines the determinants of earnings management in an international setting using the limited investor attention model of Hirshleifer and Teoh ( 2003 ). The model predicts that investor attention reduces earnings management. I use analyst following, institutional ownership, and Big N auditor choice to proxy for investor attention. I have four key findings. First, I document that financial analysts curb earnings management in U.S. firms but not in non‐U.S. firms. Second, I document that institutional block‐holdings curb earnings management across the world. Third, Big N auditors reduce earnings management in U.S. firms but not in non‐U.S. firms. Fourth, I document that corporate governance mechanisms reduce earnings management in U.S. firms but not in non‐U.S. firms.     

Little leisure in the Big Society

The Big Society is a government and governance project that brings into question the existing relationship between the state and the citizen in the UK. One aspect of that changing relationship is the way in which government is willing and able to govern the population’s discretionary or leisure time. The success of the Big Society is dependent on a reorientation of leisure time use towards civic or voluntary action. In this policy analysis, the Big Society concept is deconstructed to examine the importance of leisure as a key determinant in meeting policy objectives. Time-use evidence is reviewed to explore the difficult question of how much scope there is for a reorientation of time-use that will go some way to realising the ambitions of the Big Society. The invisibility of leisure as an operationalised policy concept is revealed as a factor that ultimately limits the success of the project. An argument for including leisure in the Big Society policy discourse and decision-making is presented.
