Rent, risk, and replication: Preference adaptation in winner-take-all markets

We study the evolution of an economy where agents who are heterogeneous with respect to risk attitudes can either earn a certain income or enter a risky rent-seeking contest. We assume that agents behave rationally given their preferences, but that the population distribution of preferences evolves over time in response to material payoffs. We show that, in particular, initial distributions with full support converge to stationary states where all types are still present. Although rents are perfectly dissipated in material terms at a steady state, efficiency is greater than if everybody had been risk neutral, since risk lovers specialize in rent seeking.     

Decomposition of Fraud‐Risk Assessments and Auditors' Sensitivity to Fraud Cues*

Practitioners and regulators are concerned that when auditors perceive management's attitude or character as indicative of low fraud risk, they are not sufficiently sensitive to high levels of incentive or opportunity risks in their overall fraud‐risk assessments. In this study, we examine whether a fraud‐triangle decomposition of fraud‐risk assessments (that is, separately assessing attitude, opportunity, and incentive risks prior to assessing overall fraud risk) increases auditors' sensitivity to opportunity and incentive cues when perceptions of management's attitude suggest low fraud risk. In an experiment with 52 practicing audit managers, we find that auditors who decompose fraud‐risk assessments are more sensitive to opportunity and incentive cues when making their overall assessments than auditors who simply make an overall fraud‐risk assessment. However, this increased sensitivity to opportunity and incentive cues appears to happen only when those cues suggest low fraud risk. When opportunity and incentive cues suggest high fraud risk, auditors are equally sensitive to those cues whether they use a decomposition or a holistic approach. We discuss and examine potential explanations for this finding.     

试析新闻发言人制度在中国升温原因及实践的基本准则

新闻发言人制度有其历史溯源与理论渊源,它在信息传播过程中在一定程度上具有对信息筛选、过滤的“守门人”品质。该制度在中国大陆重新升温主要因为：一、满足公众知情权的需要;二、应对海量信息、匡正视听的需要;三、SARS等突发事件的催化。客观真实、迅速及时、切中热点是新闻发言人制度在实践中必须遵循的基本准则。     

金融投资理论：一种基于动物精神和宏观对冲的框架

2008年全球金融危机后,金融投资理论在重新理解和抽象真实世界的基础上,对主流估值模型、投资者行为和全球宏观对冲等几个重要方面进行了深刻反思。总的来看,微观层面的进展,一是进一步认识到把投资者情绪引入传统基本面估值模型中的意义;二是利用动物精神理论发展了对投资者认知规律、决策过程和群体行为的研究。宏观层面的进展表现为提出了储蓄者和非储蓄者模型以及＂新常态＂和国际货币新体系的观念。

Abstract：

After global financial crisis in 2008,on the basis of reunderstanding the real world and putting it in abstract terms,financial investment theory has thoroughly rethought its keyaspects including mainstream valuation models,investor behavior and global macro hedging,etc. In summary,one of the developments in the micro perspective is the further realization ofthe significance of integrating investor sentiment into traditional fundamental valuation models,and another development lies in the research on investor perception,decision process and herd behavior based on the theory of animal spirits. Development in the macro perspective resides in the introduction of the model of saves and dissavers,as well as the ideas of new normal and new international monetary system.     

基于超高频数据的日内风险价值度量研究

随着金融市场的快速发展,传统的以日为单位的风险价值（VaR）已无法满足金融风险管理的需求,计算持有期小于1天的日内风险价值（Intraday VaR）显得愈加重要。文中对日内风险价值测度的方法进行了梳理、细化和改进,对测度中细节给予更加充分的考虑,最后结合我国股市特点对日内风险价值测度进行了实证研究。     

Data-driven business and data privacy: Challenges and measures for product-based companies

To leverage the opportunities provided by the Internet of Things (IoT), product-based companies are exploring new data-driven business opportunities. They may miss these same opportunities, however, owing to data-privacy challenges. These challenges start with the customers of product-based companies, extend to the wider business ecosystem, and continue with the companies themselves. This article identifies 12 data-privacy challenges and introduces 12 measures to address them. These include intuitive recommendations, such as enabling cross-product consent collection, as well as less intuitive measures, such as fostering a can-do attitude in legal units, closing the gap between legal and business initiatives, or implementing a clear process for well-reasoned risk-taking. The following four principles were found to support companies in implementing these measures: (1) letting privacy and data-driven business go hand in hand, (2) putting customers first and turning their privacy preferences into opportunities, (3) aligning risk-management activities with the process of digital service development, and (4) using technology to professionalize legal processes.     

Asymmetric risk perception and firm financing in the institutional envelope

This study investigates how asymmetric risk preferences and national institutions co-determine how firms are financed across countries. We include prospect theory into the discussion of uncertainty avoidance and the institutional envelope in IB, and argue that country-specific bias in the evaluation of downside risks and upside potentials explain variation in how otherwise similar firms raise funds. Exploiting a unique dataset on risk preferences, we show that risk perception in general, and asymmetric risk preferences as predicted by prospect theory in particular, affect corporate capital structure. We also show that the national institutional envelope constrains these effects and discuss implications for international business research beyond capital structure. We test our predictions on a panel of 10,355 firm-year observations.
