面向道德风险的易逝品供应链声誉演化研究

易逝品供应链协调问题常见于单期报童问题背景,而实际中供应链成员之间更常见的是多期合作与博弈关系。鉴于此,本论文将易逝品供应链协调问题的研究背景拓展至多期合作情形,在单边道德风险框架下研究制造商声誉的形成与演化过程,发现了易逝品供应链中制造商声誉的演化机制。最后对结论进行了数值分析和验证,并分析了各主要参数的结论的影响。     

C2C电子社区成员信誉值的计算模型研究

信任问题是关系C2C社区发展的主要因素之一.通过交易后相互评分,计算C2C社区成员信誉值并为潜在交易提供指导是建立社区信任的一种方法.通过在Sporas模型的基础上增加交易量、交易次数等变量和引入惩罚因子,提出了一种改进的C2C社区成员信誉值计算模型(E-Sporas),并针对信誉诋毁、信誉共谋这2类恶意行为设计仿真实验,检验模型的应用效果,从而为建立在线信誉系统提供一定的借鉴作用.     

控制性股东侵占行为及其负外部性研究

如何保护投资者利益免受侵害和提高资本市场效率是在转型经济背景下中国公司治理、产权制度以及金融市场改革过程中亟待解决的关键问题之一.然而,控制性股东主导的公司治理中,相对于控制性股东监督效应而言,控制性股东侵占效应是占优均衡.控制权私人收益的排他性使得侵占行为同时具有很强的负外部性.解决问题的关键在于通过动态配置决策权来建立有效的制衡机制优化公司治理机制以实现利益相关者间的互惠相容.     

管理层权力、内部控制质量与盈余管理

文章对管理层权力、内部控制质量和两类盈余间关系进行检验.研究发现:内部控制质量与两类盈余显著负相关;结构权力对内部控制质量与应计盈余具有负向调节作用,总经理两职兼任会削弱内部控制对应计盈余的抑制作用;专家权力对内部控制质量与应计盈余之间具有正向调节作用,随着总经理任职时间延长,会增强内部控制质量对应计盈余的抑制作用;声誉权力会正向调节内控质量与应计盈余之间关系.     

客户公司产权性质、审计师声誉和会计稳健性

本文利用我国A股上市公司2008-2013年的数据,实证检验了审计师声誉对会计稳健性的影响,以及不同产权性质下审计师声誉对会计稳健性影响程度的差异.研究发现,总体上审计师声誉会显著提高公司的会计稳健性水平,区分产权性质后发现,国有企业会计稳健性相对于非国有企业较高,非国有公司聘请高声誉审计师对会计稳健性有正向影响,而国有公司聘请高声誉审计师对会计稳健性不明显,非国有公司聘请高声誉审计师对会计稳健性的效应较国有公司差异并不显著.文章的结论为进一步完善公司治理和审计师声誉建设提供了一定的实证数据.     

Media reputation in initial public offerings: A study of financial news coverage in Hong Kong

This study investigated media reputation in initial public offerings (IPOs) by proposing eight attributes of substantive media reputation from environmental and product-resource perspectives. A content analysis on financial news coverage (2281 newspaper articles from 2004 to 2010) in Hong Kong was conducted to examine how print media reported financial and nonfinancial information on 38 IPO firms in the sectors of financial, properties and construction, and consumer goods. Results from partial least squares analysis showed that, although substantive media reputation and recency of news coverage together only explained a small proportion of changes in IPO share price, substantive media reputation has a significant positive effect on changes in IPO share price. Apart from the significant positive effect from the presentation tone of environmental attributes, the tone of social attributes had a significant negative effect on substantive media reputation. With the increasing concern on measuring media reputation attributes in financial news coverage across different contexts, this study contributes to the applicability of environmental and product-resource attributes in the specific context of IPOs.     

Reputation in Rupture: Broken Alliances and Relational Politics in the Roosevelt-Taft Split

Under what circumstances do close allies sacrifice their unity? By what process do bonds break? Although it might be argued that political ruptures are determined by incommensurable ideas (policies, philosophies) or by contentious personalities (temperament, character), we argue that neither explanation is sociologically sufficient. Extending the theories of interpersonal ruptures of Diane Vaughan and Robert Emerson to political domains, we take a relational approach to politics by emphasizing the centrality of the availability of reputational information, networks of supporters, and public displays of antagonism in response to affronts within systems of institutional power. Our approach to public ruptures draws on a detailed case study: the broken alliance between presidents Theodore Roosevelt and William Howard Taft, a dramatic instance of changing master-protégé relationship. The transition from close interpersonal alliance to public distaste typically involves four stages that expand a relational breach to an irreparable rupture: (1) personal grievance, (2) substantive disagreement, (3) public awareness, and (4) network activity. While every detailed case has limits, we note comparable instances and contend that this model applies broadly to broken partnerships in politics or other public domains.     

Effects of data breaches from user-generated content: A corporate reputation analysis

A threat for a growing number of firms in various industries is the occurrence of different breaches of sensitive corporate data. These critical events represent vulnerability for firms' corporate reputations, whose multiple dimensions are affected by customers negative perceptions in various ways. Further, in the Industry 4.0 era, the redundancy of scandals on social media can exacerbate negative effects. This paper reports an investigation into the effects of data breaches on corporate reputation dimensions. In this context, the study conducted latent Dirichlet allocation analysis on social media user-generated content (UGC) for a sample of 35 firms in nine industries that suffered a data breach incident between 2013 and 2016. Incidents have been categorized into three categories: “intentional and internal,” “unintentional and internal,” and “intentional and external” data breaches. The aim of the study was to discover how reputational dimensions changed after these critical events and to identify the differences among the types of data breaches.Results reveal that after critical events, more reputational dimensions appear to be relevant. While before critical events, users typically discuss the “perceived quality” of a firm's offer, after all three types of data breaches, users also pay attention to “customer orientation” and “corporate performance” dimensions. Another key reputation dimension, especially after intentional and internal data breaches, is the “firm as employer,” particularly in the context of a lack of investment in training regarding these events.These findings provide key insights for academics and practitioners to understand large-scale data breaches effects and reputational drawbacks after such incidents.     

Organizational Reputation and the Securities and Exchange Commission's Failed Regulatory Revolution

When do regulatory innovations fail? I provide a novel organizations‐based answer to this question by developing an institutional‐reputational approach to regulatory politics. Regulators cannot hope to monitor the vast majority of market activities, so they must rely on the regulated to condition their behavior on the regulator's reputation: beliefs and expectations concerning the regulator's goals and capabilities. Regulators thus pursue daily activities while being mindful of how these activities will shape their reputation and thus their ability to achieve future goals. However, even long‐standing reputations are rendered fragile when rival actors use the organization's reputation to cross‐purposes. Thus, while reputation represents a major source of power, reputation also proves fragile when organizations face conflicting reputational demands. The fragility of reputations provides a novel explanation of an understudied phenomenon: failed regulatory revolutions. I develop this theory through the analysis of innovative Securities and Exchange Commission activity in disclosure law following the Watergate investigation.
